    FIMER inverters have semi-conductor fast acting fuses on AC & DC side to protect inverter from SC and AC breaker to trip and isolate inverter during fault conditions.

    For projects on a 5 MW scale, central inverters are more suitable due to their robustness and reliability. String inverters are often more volatile, with many models in the current market not lasting more than three years.

    For projects on a 5 MW scale, central inverters are more suitable due to their robustness and reliability. String inverters are often more volatile, with many models in the current market not lasting more than three years. Since 2018, FIMER has been supplying the PVS980 series central inverters, which have proven to be reliable over time. The long-term availability of string inverters, especially for up to 25 years, is a significant concern.

    Additionally, compliance with CEA (Central Electricity Authority) regulations is challenging with string inverters. FIMER central inverters, such as the PVS980 series, are designed to meet local grid requirements and comply with CEA regulations, making them a more reliable choice for large-scale solar projects.

How to calculate the number of solar panels required for an inverter?

    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.

    Majority of Indian solar firms offer a 25-year warranty on their products. If regular maintenance is done, the product life increases considerably. Within the system, inverter warranty might be 5-8 years, and the installer itself would provide a separate 5 year maintainance and running commitment. Other than the module and inverters, the other systems can be expected to last the full 25 year period with regular checks.

    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.

    Micro inverters aid in ensuring optimal power generation from each panel in a solar project. It ensures better performnce as it can help in reducing the obstacles of partial shading. This also helps in reducing the burden of installing a central inverter and the space needed for it.

    Inverters are very important part of the solar system. Rooftop solar systems produce DC electricity. Inverters convert this DC energy into AC energy. There are multiple solar inverters in the market. Some of the manufactrers include-Sungrow, GoodWe, Solis, Deye, Luminous and Microtek.

    M R Gundurao
    Product Manager- Solar & BESS, FIMER | Answer on July 30, 2024 at 10:03 am

    A hybrid solar inverter is a piece of equipment that is created by combining a solar inverter and a battery inverter into a single unit. This allows the hybrid solar inverter to intelligently handle power coming from your solar panels, solar batteries, and the utility grid all at the same time.
