Solar Regulators. Voltech solar controller

    What are Solar Regulators / Solar Charge Controllers?

    Solar electric power systems are essentially very simple. You have a device which converts sunlight into electrical energy (a photovoltaic panel or ‘solar panel’) and this is used to charge up a battery. The battery allows you to collect energy when the sun is shining and store it until needed.

    This simple picture is complicated by the limitations of the battery. If you leave the photovoltaic panel connected to a battery, the battery will slowly charge up. If you are putting in more energy than you are taking out, then the battery will eventually become fully charged. If this continues, the battery will become overcharged and be damaged by corrosion of it’s plates and loss of electrolyte. To avoid this, some sort of charge regulator / solar regulator is used to stop the charging when the battery is full.

    Some charge controllers / solar regulators have additional features, such as a low voltage disconnect (LVD), a separate circuit which powers down the load when the batteries become overly discharged (some battery chemistries are such that over-discharge can ruin the battery).Some charge controllers may also monitor battery temperature to prevent overheating. Some charge controller systems also display data, transmit data to remote displays, and data logging to track electric flow over time.

    Pulse width modulation (PWM) and maximum power point tracker (MPPT) technologies are more electronically sophisticated, adjusting charging rates depending on the battery’s level, to allow charging closer to its maximum capacity.

    PWM vs MPPT

    The MPPT (Maximum Power Point Tracking) vs PWM (Pulse width Modulation) question is not always straight forward as it very much depends on the conditions under which charging is taking place.

    Under SPECIFIC conditions, an MPPT can have more efficiency % gains than a PWM regulator can. However when charging a 12v battery from a 12v solar panel, these gains are not present so an MPPT regulator in this scenario is unnecessary.

    MPPT is good if you need to run cables from an array over a long distance as it allows you to string the panels together in series to make higher voltage panel strings (therefore lower power loss due to cable resistance, because of lower currents).

    Other than that, MPPT is useful if you don’t want to (or can’t) match the panel specifications to the battery (e.g. on a motorhome you may want to use some uncommon, high output panels since the roof space is limited).

    Be aware that the % gains claimed for MPPT (other than the above couple of examples) are not likely to be ‘real world’ (e.g. How many hours during the day do your panels work at 25°C or less ?!). The hotter the panels become –the maximum power point voltage decreases and gets close to a typical battery voltage, therefore wiping out most (if not all) the gain an MPPT unit will give.

    The other issues with MPPT (particularly for boats at sea) is that it’s not always easy to bypass the regulator should a fault occur (e.g. due to lightning) since the panels and battery are not matched (e.g. high voltage panels and lower voltage battery). With a series regulated system (like the Plasmatronics regulators), the system can be kept running by connecting the panels directly to the battery and manually regulating.

    The Plasmatronics charge controllers are the industry standard, field proven way to take control of your battery based renewable energy system. With tens of thousands of units in service, in a huge variety of applications, the Plasmatronics Regulators has a well-earned reputation for versatility and reliability. The four stage charging algorithm incorporating true Pulse Width Modulated (PWM) constant voltage control gives you complete control over the whole charging cycle. All charging voltages and times are adjustable over generously wide ranges. This allows you to customise the charging regime to suit just about any custom requirements which you, your customer, or your battery manufacturer may have. Of course, in most cases you can choose from one of our four default programs, which cover most types of batteries and systems extremely well. Plasmatronics PL series controllers have plenty of other tricks up their sleeves as well. They can control generators, night lights, back-up battery charging, many timer applications, and heaps more.

    Plasmatronics PL20, PL40 PL80 Solar Controllers

    The PL series of charge controllers give you the freedom to operate your solar electric system the way you want to.

    They offer complete control over the charge cycle, plus an unprecedented amount of useful information about current and past performance.

    PL regulators help to protect the system with a built in low battery disconnect switch. In addition, the versatile event controller can switch power on or off according to criteria set by the user. This allows the PL to do extra tasks such as switching a light on at night or keeping a water tank full by operating a pump when needed.

    The user can select either Pulse Width Modulation or slow speed switching. Regulation can be done in both series and shunt modes. Other features include backup generator control and charging a second battery.

    The PL Series is designed for Caravan / Motor-home / Camping systems, as well as Commercial and industrial stand alone applications.

    Informative:

    A comprehensive LCD display gives battery voltage, charge current, Ah in and out, load current, battery temperature (with optional sensor) and more. System performance data is available for the last 30 days. The controller remembers what happened, even if the user might not.

    Well Connected:

    With the optional PLI interface and PLCOM software, the user can access all the functions from a remote computer. All data can be read, and all settings adjusted.

    Versatile:

    Because it can handle 12, 24, 32, 36, and 48V systems, and be set to deal with any battery requirements, you can use it in almost any battery charging job. It may be the only regulator you will ever need to stock. (Higher voltages available on special order).

    Features:

    NOTE: Due to high current in-rush on start up, Inverters are to be wired to the battery bank and not directly to the Load Terminal. Doing so could damage Regulator and void warranty.

    Plasmatronics Dingo 2020N Solar Controller

    The Dingo2020N is the next generation charge controller from Plasmatronics. It inherits many of the best features of the PL series of controllers. But, thanks to Plasmatronics extensive industry experience and a wealth of customer feedback, the Dingo2020N is in a class of its own.

    The Dingo Series controllers were designed to be used in Caravan / Camping / Marine applications as well as Stand Alone Commercial and Industrial ones. However, the main applications its designed for is vehicle systems, such as Campervan, Motor-home, Caravan, Cars, Trucks and boats. As Its easier to understand for people used to working on vehicle systems, due to the Negative grounding

    The Dingo series of solar controllers is exceptionally versatile. They give the user unparalleled capability to adjust the function of the controller and to monitor the performance of the energy system. To cater for non technical users, the Dingo has four preset programs which can be used without needing to understand the details of its operation. For those with a good understanding of solar regulation, there is another program, which allows all the settings to be adjusted if required. Once the program has been selected, it is possible to disable any further adjustment. This prevents unauthorised adjustment of settings. Although the Dingo is primarily a device to control the charging of batteries from solar electric (photovoltaic) panels, it can also be used with other energy sources such as wind, micro hydro and fuel driven generators. The Dingo supports a variety of regulation methods. It supports slow speed switching and fixed frequency pulse width modulation (PWM) control in series and shunt modes. Low battery voltage load disconnection is provided, as are an alarm, facility to control the charging of a second battery bank and control for a back up generator. The event controller can be used to control lights, pumping, waste energy use and other timer functions. A temperature sensor can be added to correct the regulation voltages for battery temperature. There is an input for measuring external voltages. A serial interface is provided for accessories including extra switch blocks, remote current sensors and communication with a computer/ modem. Using an external current shunt attached to a remote current sensor (DSA) allows the controller to see other current flows in the system. The Dingo can control larger systems by adding external switch blocks attached to the serial bus. The DUSB, D232 or DNET interfaces allows remote monitoring and adjustment. Custom settings can be stored on a computer and uploaded into the controller. Data from the controller can be downloaded into the computer and displayed easily.

    What’s the same:

    • Reliable, easy to understand, one button interface and proven, easy to learn menu structure.
    • Symmetrical charge and load currents, both 20A.
    • Industry standard four stage charging regime.
    • 12,24,32,36 and 48V selectable. Only one controller to stock.
    • Unbeatable high temperature performance. Full charge and full load current, without interruption to operation, in a 50oC ambient. All day, every day.
    • Fast, reliable, affordable, Plasmatronics Service, long after the long warranty has expired.

    What’s new? Nearly everything else! Without any exaggeration, much too much to list here. Highlights include:

    • Negative Ground: This makes it much easier to use in vehicles and easier to understand for people used to working with vehicle systems. The Dingo works well everywhere, but shines in campervan’s, motor homes, caravans, cars, trucks and boats.
    • New Communications Bus: This rugged new bus uses the MODBUS protocol (industrial automation standard proven in noisy environments). Aside from accessories you would expect for a PL descendant like shunt adaptors and data interface units, it is also compatible with Modular System Components. This gives unprecedented flexibility in system design.
    • Data Storage: 512 days worth of data can be stored. That’s 16 Months worth of Charge and Load Ah, Battery voltage range, and daily State of Charge. Data for 99 days is accessible via the display so if you don’t have a computer, you’re not locked out.
    • Enhanced one button interface: Now includes Reverse gear for when you want to go backwards and Fast Forward for when you need to set a very large number (e.g. a large battery Ah capacity.)
    • LED backlighting: Makes the display readable in any light conditions.
    • Hidden Wiring: All the wires are covered. Wiring to the unit can be kept out of sight inside the wall or behind the mounting panel. This makes for a clean installation. The user gets the access they want without making their living space into a distribution board. Especially valuable in mobile applications.
    • terminals: A terminal for every wire. Wiring is simpler and quicker. External electrical commoning points or bus bars are not needed and it is easy to understand where the wires should go.
    • Generator Terminals: Voltage free contacts, as required by many generator start systems, are now included in the basic controller.
    • Accessories: The Accessories available so far include shunt adaptors (DSA) and two different data adaptors (DUSB and D232).
    • The DSA reads external charge or load currents: You can use up to 4 per system.
    • The DUSB provides a USB interface to a computer: This allows the user to download all the data from the controller and change settings if required.
    • The D232 provides an RS232 interface (DTE): Designed for remote computer access via a modem.

    Victron Energy SmartSolar MPPT 100V 20A 12/24/36/48V Solar Controller With Bluetooth

    A solar charger gathers energy from your solar panels, and stores it in your batteries. Using the latest, fastest technology, SmartSolar maximises this energy-harvest, driving it intelligently to achieve full charge in the shortest possible time. SmartSolar maintains battery health, extending its life.

    solar, regulators, voltech, controller

    The SmartSolar charge controller will even recharge a severely depleted battery. It can operate with a battery voltage as low as 0 Volts, provided the cells are not permanently sulphated or otherwise damaged.

    MPPT: Ultra Fast Maximum Power Point Tracking

    By constantly monitoring the voltage and current output of your solar (PV) panels, MPPT technology ensures that every drop of available power is rinsed out of your panels, and harvested for storage. The advantage of this is most noticeable when the sky is partially clouded, and light intensity is constantly changing.

    Remote Monitoring and Control

    Remotely control and monitor the extensive features of your SmartSolar MPPT charger with built-in Bluetooth by pairing it with your smartphone or other device via VictronConnect. If your installation is connected to the internet with a GX device, the Victron Remote Management Portal (VRM) provides access to the full power of your MPPT, anytime, anywhere; both VictronConnect and VRM are free to use.

    Load output

    The intelligent Load output function prevents damage caused by running batteries ‘flat’. You can configure the voltage at which SmartSolar disconnects a load – thereby preventing excessive drain on your batteries. And here’s the clever bit: SmartSolar will attempt a 100% recharge every day. If it can’t – during periods of poor weather – it raises the disconnect voltage, daily, until it achieves success. We call this feature BatteryLife because it maintains the health, and extends the life of your battery.

    What are the Solar Battery Charging Stages?

    Home » FAQ » What are the Solar Battery Charging Stages?

    Solar charge controllers put batteries through 4 charging stages:

    What are the 4 Solar Battery Charging Stages?

    Bulk Charging Voltage

    For lead-acid batteries, the initial bulk charging stage delivers the maximum allowable current into the solar battery to bring it up to a state of charge of approximately 80 to 90%. During bulk charging for solar, the battery’s voltage increases to about 14.5 volts for a nominal 12-volt battery.

    Absorption Charging

    When Bulk Charging is complete and the battery is about 80% to 90% charged, absorption charging is applied. During Absorption Charging, constant-voltage regulation is applied but the current is reduced as the solar batteries approach a full state of charge. This prevents heating and excessive battery gassing. At the end of Absorption Charging, the battery is typically at a 98% state of charge or greater.

    Float Charging

    Float charging, sometimes referred to as “trickle” charging occurs after Absorption Charging when the battery has about 98% state of charge. Then, the charging current is reduced further so the battery voltage drops down to the Float voltage.

    The Float charge of a battery keeps the battery at maximum capacity throughout the day.

    Equalization Charging

    For flooded open vent batteries, an Equalization charge is applied once every 2 to 4 weeks to maintain consistent specific gravities among individual battery cells. The more deeply a battery is discharged on a daily basis, the more often equalization charging is required. Solar Charge Controller Equalization is for flooded, not for sealed, GEL, or valve-regulated batteries which can be damaged by equalization.

    Figure 3: Multi-Stage Battery Charging Diagram

    Although lead-acid batteries are the most common type of battery regulated by solar charge controllers, lithium batteries are starting to gain traction. Morningstar launched an Energy Storage Partner program that involves working with many lithium iron phosphate battery manufacturers to maintain the highest state of charge for their batteries and to help maximize battery life.

    The integration guides you can download provide custom solar charge controller voltage and time settings for absorption and float charging, and other information that you will need to charge your batteries safely and to increase their longevity. In addition to lead-acid and lithium, Morningstar solar charge controllers can also charge nickel, aqueous hybrid ion, and flow or redox flow batteries.
