    String inverters are electrical devices that convert the direct current (DC) generated by solar panels into alternating current (AC). They are usually installed in a string formation where multiple solar panels are connected in series to form a single circuit. They differ from central inverters in terms of capacity as central inverters are designed to handle large amounts of power at a fixed frequency.

    The PM-KUSUM (Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan) scheme is a government initiative to promote solar energy in rural areas. Under Component-A, farmers in Assam can lease their land to set up small solar power plants (up to 2 MW) near 33/11 kV substations. This allows farmers to earn extra income from their land while contributing to clean energy production. The 357 MW project by Assam Power Distribution Company Limited (APDCL) aims to make this opportunity accessible to farmers across the state.

    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.

    Pradhan Mantri Kisan Urja Suraksha Evam Utthaan Mahabhiyan Yojana is a scheme to subsidize farmers to install solar irrigation pumps for cultivation. Each farmer will receive a 60% subsidy to set up tube wells and pump sets.They will also get 30% of the total cost as a loan from the Government. the scheme is administered through relevant state government bodies in each state.
    there are three main components in PMKUSUM. Component A, or Groud Mounted Solar plants that will be grid connected, and built on land provided by Farmers.

    Component B or off grid solar irrigation pumps.

    Component C or grid connected solar irrigation pumps.

    Overheating, Surges & Spikes

    One common reason for solar inverter failure is overheating due to lack of proper maintenance. Solar inverters are often installed in outdoor environments where they are exposed to sunlight and high temperatures. Over time, this exposure can cause the internal components of the inverter to overheat, leading to performance degradation and eventual failure. Inadequate ventilation or improper installation can exacerbate this issue, underscoring the importance of proper system design and maintenance.

    Another factor contributing to solar inverter failure is electrical surges or spikes. These can occur due to lightning strikes, grid voltage fluctuations, or switching events within the electrical system. While inverters are equipped with surge protection mechanisms, they are not immune to damage from high-voltage transients. Investing in additional surge protection devices and implementing proper grounding practices can help mitigate the risk of damage from electrical surges.

    Components & Firmware

    Component degradation and manufacturing defects are also potential causes of solar inverter failure. Over time, the internal components of inverters, such as capacitors and semiconductors, can degrade due to exposure to heat, moisture, and electrical stress. Regular monitoring and proactive maintenance can help identify early signs of component degradation, allowing for timely repairs or replacements.

    Furthermore, software and firmware issues can affect the performance and reliability of solar inverters. Firmware bugs, compatibility issues with other system components, and software glitches can all lead to malfunctions or operational errors. Keeping inverters up-to-date with the latest firmware releases and working with reputable manufacturers can help minimize the risk of software-related failures.
