    Heliso-485MCP 5KW off grid high temperature and out current "0" (out kw "0") problems
    Hello there 11 pieces of FB38N20D mosfet (the block close to the fan side) located at the input ends of the Heliso-485MCP 5KW off grid inverter battery is overheating. Since the inverter protection temperature is 90 degrees, the inverter output cuts when it exceeds 90 degrees. No malfunction was encountered in the rompanent measurements. Previously, 3 mosfets of IRFP4668, which were in the MPPT section, were faulty and were replaced. After this fault, the current is constantly showing "0" at the inverter output. therefore, the output power appears as "0".
