Hello.
I’ve been operating an off-grid system in Spain for three months and have a small problem.
First, my system configuration:
5 kW PV divided into four strings, each with an MPPT 150/35, Multiplus 2 48/5000, Cerbo GX, and 4 Pylontech US3000.
GO-e Gemini EV charging station for single- and three-phase charging.
Charging only with single-phase 230V.
Now comes the problem: The EV is a 2023 Renault Zoe. It’s already known that the Zoe is a “charging Zicke” Charging isn’t working, presumably because of a grounding problem. The grounding isn’t great because the house is built on rock. Is there a special setting on the Multiplus, or perhaps another trick (running the ground wire to the vehicle)? I tested it with the charger (accessory) on a regular mains power supply, and the vehicle charges without any problems.
