I'm operating a 4,8kW Peak PV System with a Huawai Inverter. Recently I've added MultiPlus-II 48/3000/35-32 GX with a 175ah Battery. A Victron Energy Meter ET340 measures the residual load and provides the information to the victron.
I'm operating the MP 2 with ESS to charge the surplus of the PV system into my battery or to level my grid demand to zero to the extend it is possible. When I'm charging my electric vehicle with 6 kW, I'm utilizing the PV system and MP 2 at the maximum possible power supply.
At this load level the MP 2 is quite unreliable. For a short period it works as expected until the voltage and current drops until discharging starts again (see Video)
Charging is not effected and works as expected at the same rate.
