OK, I recently completed installation on my Victron MultiPlus-II 12/3000/120-50 120/240V Charger/Inverter along with a SmartShunt 500A and 200AH of 12 LiPO batteries and Cerbo GX in my RV. I have not gotten a chance to install the PV system yet. Everything works great, but I am trying to tweak my settings. What I am noticing is that when I am in Bulk and Absorption, my batteries charge to 100% SOC. Once it goes to float, the parasitic drain of the 12v system (approx 23w) slowly drains the battery SOC down.. I haven't see how low, but I was wondering is this normal? Shouldn't the charger keep the battery at 100%? Is it possible I didn't correctly configure my SOC? If so what is the typical conditions to zero out the SOC? Is this maybe how the system protects the longevity of the batteries? Sorry for the rookie questions, just in all my research I haven't seen anything about this. I just want my system to be charged to 100% when in use so that if we loose or need power I'm not starting at 80% SOC. Any suggestion would be appreciated.
