    It is not the number of solar panels but the total power (in Kwp) that the solar panels can produce. Usually your inverter should align with the expected maximum power the solar modules can produce. So normally if you have a 3 kW of rooftop solar, you will need a 3 kw of solar inverter.

    1. Solar Inverter Battery

    Your inverter’s endurance depends significantly on its battery. Hence, choosing the right battery matters. Your battery’s capacity is defined as the maximum number of hours for which a battery can power all devices. Accordingly, you should assess your energy needs and the average time for which you will require the solar inverter and make an informed decision that helps you optimize the use of solar power.

    2. Safety Certification

    This one is another essential consideration. You must check the solar inverter for its level of safety. It is crucial to choose a solar inverter certified for its safety by an independent testing authority before you purchase and use it for your solar venture.

    3. Inverter’s VA Rating Range

    Check the inverter’s VA rating or VA capacity to determine the solar inverter’s output. The VA rating depends on your consumption of power. Higher power consumption refers to a higher requirement of the inverter’s VA rating.

    4. Peak Power Considerations

    Solar inverters are usually expected to supply two types of power – peak and typical power. Now, what are peak and typical power?
    Peak power is the optimal power a solar inverter can supply for a trivial duration, which could be between a few seconds to around ten to twelve minutes. Some appliances require higher power while starting up than they do to operate under normal circumstances after being powered.

    On the other hand, typical power is the usual power that the inverter supplies consistently
    after the device receives its power to begin and stabilize.

    5. Inverter Brand

    It is another critical factor to consider. While it is a no-brainer to choose the most popular and the best solar inverter brand, what matters is whether the brand you select enables you to reap optimal returns. Accordingly, you should choose solar inverter brands that offer the features, efficiency, and proposition that allow you to achieve the energy self-dependence you’ve always endeavored for.

    1. Decreased Energy Production:

    One of the most noticeable signs of detecting a faulty solar inverter is a decrease in energy production. If you’ve observed a significant drop in the amount of energy your system is generating, it could indicate an issue with the inverter.

    2. Error Messages:

    Modern solar inverters are equipped with diagnostic features that display error messages in case of malfunctions. Keep an eye out for any error messages.

    3.Frequent Tripping:

    Is your circuit breaker frequently tripping? While it could be due to various factors, a malfunctioning solar inverter is one potential cause that shouldn’t be overlooked.

    Solar inverters are safe to use as it included all main protection systems inbuilt like overcurrent, overvoltage protections. Proper grounding and safe installation standards should be ensured while installation.

    • Keep the Inverter cool by ensuring the fan, ventilation system, or other cooling technology is up to speed and working correctly.

    • Keep the air intake filter clean to ensure there is no clogging, preventing the free flow of air and preventing moisture from building up internally.

    • Check for Error Codes or changes in the inverter lights; these could be signs that something is amiss and needs attention.

    • Use Solar Monitoring Technology whenever available from your solar equipment supply company. Whether they are apps or alert systems of any kind, they can help monitor performance and spot issues before they escalate.

    First, make sure that the power supply to the inverter is turned on. This means checking whether or not the breaker is tripped or if the power cord has become disconnected. If these do not seem to be the problem, proceed to reset inverter.

    • Reset the solar inverter by turning it off and then back on again. Be sure to wait for a few minutes before trying to turn the inverter back on, as this will give it time to power down completely.

    • If your solar inverter is still not working after following these steps, you should contact a professional for help. A qualified technician will be able to diagnose and fix the problem quickly.

    Check inverter display for any failure. Recent events may be viewed for better resolution.
