Arrays of photovoltaic (PV) modules, mounted on metallic structures, always create stray capacitances between active conductors and ground. Thus, leakage currents flowing in these ground capacitances are formed. If the number of PV modules array is high, these.
If the continuous residual current exceeds the following limits, the inverter should be disconnected and send a fault signal within 0. 3s: For the inverter with a rated output less than or equal to 30KVA, 300mA.
The inverter output current is approximately 9. If that same 1000-watt load is supplied at 230 volts with the same power factor, the current falls because the voltage is higher.
This means your solar panel is generating voltage (open circuit), but the circuit is incomplete and therefore cannot generate current. This could be due to a loose or broken wire, a faulty inverter or charge controller, a poor connection, or an internal problem with the panel.
