    Inverters

    Most homes are wired for AC electricity, but most solar panels and small wind turbines produce DC electricity. Solar inverters convert direct current (DC) electricity into alternating current (AC) electricity. Because of this, unless your solar system runs DC only, an inverter is usually a central component in both off-grid and grid-tie solar systems. Each type of system requires a different type of inverter:

    • Off-grid inverters where a charge controller sends DC power to a battery bank, then an inverter converts the DC to AC for the home.
    • Grid-tie inverters with no battery bank, DC power goes straight to the inverter, and then to the home as AC. Excess AC power is sent backwards through a special two-way net meter, and out to the power grid for others to use. Your meter runs forward or backwards depending on if you are buying or selling power at the time.
    • Hybrid inverters connects to both a battery bank and the utility grid, letting you draw or send power from both.
    • Battery based inverters are best for small projects or when the grid is not available at your location.
    • Grid tie string inverters are best when you don’t have a lot of shading.
    • Micro inverters are best when you have shade on some of the roof or multiple roof orientations.
    • Hybrid inverters are best you want solar and batteries and be connected to the grid.
    • Mobile inverters are best when you’re on the go, in the RV or on the boat.

    Designed for one or multiple inverter applications, Mini Magnum Panel (MMP) enclosures make it easy for you to mount all of the major components required for a solar power system. Magnum Panel enclosures feature convenient front panel operation, and when used with the optional Magnum Router, the MMP will allow you to easily set up, monitor, and operate up to four Magnum MS-PAE inverter/chargers together.

    Sizing an Off-Grid Solar Inverter

    Choosing the right off grid inverter for your off-grid solar system depends on accurately calculating your electrical loads and usage patterns. The size of the inverter you need is based on your ‘peak load’ requirements. all the AC loads that could be turned on simultaneously.

    For example, if you will be using the 1500 watt microwave, while also running 100 watts of lighting and running a refrigerator that will draw 500 watts of power, you will need an inverter that can handle at least 2100 watts (1500 100 500). Once you have identified a minimum wattage, you will select a style that has the same nominal voltage as your battery bank (12, 24, or 48 VDC).

Watch and learn more about this 12 volt variety!

    Sizing a Grid-Tie Solar Inverter

    Grid-tie inverters connect directly to the utility grid and do not require batteries. A battery-less system is much less complex (and less costly) than a system with batteries. The main drawback is that a grid-tie solar system without batteries cannot supply power to the home in the event of a power outage. For the safety of the people working on the utility lines, grid-tie inverters will shut down until power has been restored. If frequent power outages are not an issue, then a utility grid-tie system can be an excellent, cost effective option.

    To qualify for most state rebate programs, you must be connected to the utility grid. We recommend you visit dsireusa.org/ for the most up to date list of solar and renewable energy incentives in your local area.

    Sizing a grid-tie inverter can be a bit more complex than sizing one intended to be used with batteries. Each inverter manufacturer offers a string sizing tool that will display the acceptable configurations for your PV array, based on the quantity and wattage of your solar panels. These string sizing tools also account for variations due to high and low temperature extremes.

    Can A Hybrid Solar Inverter Work Without Batteries

    When you first have a solar system installed for your home or business, the first thing you will need is an inverter. An inverter is a device that converts DC power to AC power.

    The electricity grid and most appliances run on AC power while solar panels produce DC power which can be stored in solar batteries.

    As home energy storage system has gained in popularity, a new type of advanced inverter has been developed known as a hybrid inverter.

    Different Types of Inverters

    The three main types of inverters include solar, hybrid, and off-grid inverters which are powerful battery chargers. There are two main types of solar installations, on-grid, and off-grid:

    These are the most common and generally the most affordable type of solar systems available that use a simple inverter to convert DC power from the solar panels into AC power that can be directly fed to the grid for use in your home.

    These systems are more complicated as they involve a combination of solar panels and battery storage.

    With these types of installations, multiple inverters are required that include a solar inverter and a sophisticated battery charger to manage the grid connection as well as charging and discharging of batteries, also known as multi-mode inverters.

    These advanced interactive inverters are able to integrate solar and battery technology into an all-in-one hybrid inverter.

    Solar Inverters

    There are two types of solar inverters – string and micro-inverters.

    All over the world string solar inverters are the most common type used due to the simple installation and low cost involved. They come in single-phase and three-phase versions.

    Most residential homes in Australia and the US use single-phase power while in Europe 3-phase power is used. Factories and businesses also use three-phase power.

    These are very small inverters that attach to the back of a solar panel and can only convert power from one or two panels from DC to AC.

    Hybrid and Battery Inverters

    A hybrid inverter combines a solar inverter with a battery inverter into one unit. This is a very economical way to enable load shifting or self-use of energy.

    It allows off-peak or solar energy to be stored in a battery for later use during peak times. However, these all-in-one inverters are not able to function during a power outage such as a black-out.

    They also have limited monitoring capabilities and functionality.

    If you need a hybrid inverter capable of powering the entire home during a power outage then you will need back-up power from an interactive inverter or UPS (Uninterruptible Power Supply).

    Solar Panel Installation Without Battery Power As A Backup System

    A hybrid solar inverter can work without batteries. This type of system is attached to solar panels and to the power grid which supplies power from both.

    The energy produced by the solar panels is directed to the house for use and they do not need to produce all the electricity to run an entire household as shortfalls can be made up from the power grid.

    Advantages of installing solar power without battery backup include:

    • Savings on electricity bills
    • Less costly to install
    • environmentally friendly
    • Fewer components to maintain

    However, a major disadvantage is that it will not provide power during a black-out or power outage. An installation with battery backup includes batteries that allow electricity to be stored for later use.

    Different battery banks vary in size and are charged by both the solar panels and the power grid. The advantage is that the lights stay on even during a power outage.

    However, it is more costly to install and there are more components to maintain.

    If you live in an area where there is a constant, reliable power grid, a solar power installation system without battery backup will be ideal as it will save you money.

    Can I Use Solar Panels Without Battery Storage?

    With all the buzz about energy storage, you might be wondering if a solar battery bank is an essential for home solar systems. Can you even use solar panels on your home without battery storage?

    The short answer is, yes you can. Although there are advantages to having a solar battery backup in certain situations, it’s not essential for everyone.

    In this article, we’ll explore some scenarios in which having battery storage with solar panels is beneficial, and some in which sticking with simple rooftop solar panels could be the way to go.

    How to Use Solar Panels Directly Without Battery

    If battery storage isn’t in the cards for now, don’t worry! You can still use your solar panels to power your home without battery storage. In fact, a majority of home solar systems aren’t connected to battery storage.

    Here’s how it works:

    Early morning and evening are times with lower solar production, but higher energy needs. You’re waking up and getting ready for the day, or making dinner and doing homework with the kids. That’s when you’ll need a lot of power, but also when solar panel production is just getting momentum or tapering off.

    During these times (and especially at night) solar owners without battery storage draw power from the grid, which acts as a giant energy backup system.

    But during the day your solar panels are likely providing more than enough energy to power your home. The excess energy is sent into the grid to power your local community.

    Simply put, when the sun’s shining, you use your own solar power and send excess power to the grid; when it’s not, you draw from the grid.

    This kind of setup is called a grid-tied system. You essentially use the local utility grid as a battery to “store energy” without needing a solar battery bank in your home.

    If you have your own battery storage, you likely won’t transfer much energy to or from the grid. You store your own energy and pull from that, and the grid serves as a backup to the backup.

    Net energy metering

    If you live in a state with net energy metering, you earn credit for sending your excess energy to the grid. At the end of the year, those credits are used to offset the cost of the energy you pulled from the grid. With just a recent energy bill, solar.com can generate multiple quotes for solar systems that offset 100% of your electricity use.

    That means instead of paying for grid energy, you’re only paying for your solar equipment. And once you’re equipment is paid off, you’re paying nothing for electricity!

    Do I Need Battery For My Solar System?

    It many cases, battery storage is a “nice to have” with solar panels for home use. However, there are a growing number of scenarios where having a solar battery bank is beneficial, if not completely necessary.

    Scenario #1: You experience frequent or prolonged power outages

    First, if you live in an area with one or more of the following, battery backup is a good idea.

    A home battery bank is especially crucial if you have essential systems — like medical equipment or an electric well pump — that you need to power when the grid is down. In fact, the Self-Generation Incentive Program (SGIP) in California offers rebates up to 100% of the cost of battery storage for Californians in these circumstances.

    Florida is another state where frequent and prolonged power outages make solar and battery beneficial.

    Scenario #2: You have a unfavorable net metering policy

    In addition to backup power, battery storage can also be a means to greater energy cost savings. Energy utilities in many states are working to remove or replace net metering policies. In California, for example, the proposed NEM 3.0 policy would reduce the value of solar exports by around 75%.

    Currently, California solar owners are earning around 30 cents per kWh for the excess energy they put on the grid. Under NEM 3.0, they would earn closer to 8 cents per kWh, in which case it makes more financial sense to have a battery bank to store and use your own solar electricity.

    There are also states and utilities with no net metering policies at all. In these areas, it makes more sense to store and use your own energy instead of putting it back on the grid.

    Scenario #3: Your utility has Time of Use rates

    In some places, the price of grid electricity fluctuates throughout the day based on demand. This is known as time of use rates, or TOU.

    Typically, electricity is most expensive in evening when people are home cooking, watching TV, and running heat or AC. Unfortunately, solar production isn’t great in the evening, and solar owners end up pulling from the grid.

    With battery storage, you can not only avoid peak pricing, you can take advantage of it by using — or even exporting — cheap solar electricity generated and stored during the day. This is especially beneficial if you have large electrical loads such as electric heat, air conditioning, or an electric vehicle.

    Scenario #4: You want to be energy independent

    If you live in a remote, isolated area without a central utility grid, you will need a battery storage device to capture your solar generation for later use. This is essential if you want to have the lights on at night when your system isn’t generating.

    Even if you are within reach of a utility grid, many people prefer to generate and store their own clean electricity. Most utilities rely on fossil fuels to generate electricity. By pairing solar and battery storage, you reduce the demand for dirty energy.

    Fortunately, the Inflation Reduction Act expanded the tax credit to 30% of the gross cost for battery storage. Learn more about the Residential Clean Energy Credit for battery storage here.

    Is It Okay to Use Solar Panels Without Battery Storage?

    Absolutely! In fact, most home solar systems are currently operating without battery storage.

    If you’re fine with drawing from the grid and not particularly worried about power outages, you might not need a battery.

    However, there are benefits to having battery storage for your solar panels. In addition to backup power, battery storage is becoming more beneficial as net metering policies change and more utilities adopt time of use rates. It’s also a means of achieving energy independence and ditching fossil fuels altogether.

    Frequently Asked Questions

    Can I use solar panels and inverters without battery?

    Yes, if you are connected to an electrical grid, you can use solar panels and inverters without battery storage. However, it’s important to note that grid-tied solar systems are usually shutoff during power outages to prevent the backflow of electricity from harming utility workers.

    A few inverter manufacturers, namely Enphase and SMA, have products that allow you to directly power essential loads during blackouts even without battery storage. This is called “islanding” your solar system.

    How does solar work without batteries?

    Without battery storage, solar systems typically to use the utility grid as a battery. Solar energy is first used to directly power your home and the excess energy is pushed onto the local grid to power neighboring systems. When the solar system is underproducing, the home draws electricity from the local grid.

    Through net metering, homeowners earn credit for the excess energy to offset the energy they pull from the grid. This allows solar owners to essentially replace their electricity bill with lower payments on their solar system.

    How to store solar energy without batteries?

    In most residential settings, excess solar energy is “stored” on the local utility grid. And by “stored,” we mean used to power your neighbor’s house.

    So, if you produce more solar electricity than your home needs, the excess sent onto the grid and used to power neighboring systems. This not only reduces demand from the central utility, it reduces wear on the grid because as the electrical current travels less distance.

    For commerical applications, there are a number of ways to store solar energy without batteries. According to the EPA, these include:

    • Pumped hydroelectric
    • Compressed air
    • Flywheels
    • Thermal energy storage

    Potential energy comes in many forms — not just rechargeable batteries!

    Hybrid inverters are at the heart of any simple, cost-effective solar battery storage system and store excess solar energy to increase self-consumption and provide backup power. These inverters work much like solar inverters but have an integrated battery charger and connection in one simple unit. For the system to know when to charge or discharge the battery, hybrid inverters require an external energy meter (CT) to measure the electricity consumption, along with software that can be programmed to determine the most efficient use of your available solar or battery energy.

    Hybrid inverters are a simple and economical way to add battery storage, but they do have some limitations compared to dedicated off-grid battery inverters, the main being limited surge or peak power output in the event of a blackout. Also, some hybrid inverters do not have backup power capability, or the backup power is limited, so only small or essential loads like lighting and basic power circuits can be backed up in the event of a blackout. For a detailed guide to selecting and sizing a hybrid inverter, off-grid inverter or energy storage system, see our Technical guide to designing hybrid and off-grid solar systems.

    hybrid inverter Comparison Chart 2023

    Description of hybrid solar inverter features:

    • DC coupled HV. Only compatible with High Voltage (HV) battery systems such as LG RESUH or BYD HV.
    • Operating MPPT voltage range. Most manufacturers specify the full operating MPPT voltage range, while others provide the optimal MPPT voltage range for maximum power and efficiency. Outside the optimal voltage range, the inverter will still generate power but at a reduced capacity. Refer to manufacturers’ datasheets for full details.
    • Surge Power. The maximum surge power rating and duration depends on the load type (resistive or inductive) and ambient temperature. Higher temperatures above 40degC will generally result in a reduced surge power rating.
    • DC Optimisers = Panel-mounted optimisers provide individual panel power optimisation and monitoring.

    Note, battery storage can be added to an existing solar installation using an AC-coupled hybrid inverter such as the Sunny Boy Storage from SMA. Another option to retrofit batteries to an existing system is using an AC battery system such as the Tesla Powerwall or Sonnen ECO.
