Hello together, so I bought this Hehn 580 WoMo and I still have a solar cell (50W) with loader controller. I had already installed the solar cell on my old WoMo Ford Transit Bj.82, but had to separate the system from the battery before the start by means of a switch. Does anyone have experience in how to connect the system so that no electricity is drawn from the solar installation when starting.? Greeting from the Bergstrasse nughatt
