I might stretch my brain and see whether the Arduino route might be more appropriate. I either need to stick with low powered circuitry operating at either 24 or 48 volts or obtain some very technical advice and circuitry practices before I attempt to look at higher powered bridge circuits for bigger inverters. I then purchased a kit from AliExpress featuring the identical components and this also would not work and destroyed several drive pcb's. The driver chips, IR2110 & 2113 are designed for high voltage applications but something is clearly not good with the EGS002 circuitry as I cannot trace any faults that could cause such major failures. I have tried to produce a high voltage bridge circuit with a 360v DC rail but have destroyed several EGS002 modules and a few output devices. I have incorporated a very small isolation transformer in my feedback circuit to ensure none of the output is seen on the pcb so everything is isolated between the low voltage battery side and the high voltage AC sections. For low voltage work, these modules are very good and operate well. This is essentially for emergency lighting applications where LED lamps are being used. ![]() I have used quite a few EGS002 pcb's for inverter projects where the DC voltage is from 2 x 12v batteries and my purpose designed pcb incorporates changeover circuitry and a small constant current constant voltage charger for sealed lead acid batteries.
