I have a question in regards to the setup of my solar panels (12V, 600W) and the Victron 150/70 MPPT charger on my RV. The MPPTs manual does NOT recommend for a 12 V electrical system a parallel panel setup that leads in my case to a MPP voltage of 18V. In the RV world it is widely recommended to set up the panels in parallel to avoid the negative impact of shading. Is Victron’s recommendation entirely based on the power losses/ or need for high cross sections in the wiring ? Or is there an additional performance loss due to a higher inefficiency of the MPPT. I could imagine that due to the smaller gradient between PV voltage and Supply voltage the MPP algorithm is less effective in finding the optimum.
