I live in France.
In my van, I have three solar panels (330W each), a Victron 200Ah Lifepo4, a Victron MPPT 150/100.
I have been relying only in solar to charge the Lifepo4. But I have never known a real winter.
This week, I am considering how to install my Phoenix inverter 12/375 and a Victron IP22 charger 30A.
Do I need to ground the inverter to the van chassis or to the minus of the Lifepo4? Actually, do I really need to ground the inverter as it will remain inside the van?
Regarding the Victron IP22 charger, this afternoon I have mounted a male CEE17 plug under the chassis of the vehicle and passed a cable from it inside the van. I will only connect the IP22 charger to this cable. Do I need to install a 30mA residual current device or breaker with overcurrent protection or another protective device for the IP22? Do I need to ground the vehicle chassis to the earth each time I want to use the IP22 charger?
