2.4 Wiring inverter in parallel

SE inverters can be connected in parallel when more power is requested. In the parallel configuration, each inverter shall connect to its own
PV array. It is not recommended to connect one PV array to more than one inverter. This may cause the inverter to work abnormally. Fig. 2.4.1.
and 2.4.2. show.
