Solar inverters comparison. Types of Solar 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.

    • Customer Service. When you buy PV solar inverters, you should receive a proper consultation or even guidance from experts. In case of any inquiries, the seller or manufacturer itself should address them;
    • Warranty. Ensure your inverter has a good warranty to rely on. At least 10 years should be there. Otherwise, you will simply come across huge expenses on repairs and maintenance;
    • Extra perks. Modern inverters come with extra features. For instance, there should be convenient panel-level optimization;
    • Solar inverters price. Agree that a price greatly dictates your choice. So, ensure it is neither exorbitant nor cheap. Find a golden mean.

    Best Commercial Solar Inverters in 2023

    If you seek commercial solar inverters, you can find the below examples a good fit.

    Check the Durability of the Inverters

    Purchasing a solar inverter should be a long-term investment. It is, therefore, crucial to consider performance and lifespan under adverse weather conditions.

    Australian weather can be particularly harsh in the summer months so an ability to handle high temperatures is usually a top priority. Yet, you should also be aware of any potential issues arising from interactions with the cold or rain.

    Usually, high temperatures raise the solar power system’s voltage, and low temperatures decrease its voltage. Once the voltage exceeds the maximum specification, it can cause irreversible damage to the solar inverter.
