High in the southern french Alps, my house is powered by 2kWp on the roof, 30kWh OPZS lead batts and a 3kVA generator all manages by a full Victron system. The last 3 months the sun has been scarce and erratic but I kept my Multiplus 24/5000/230 running to keep a fridge and a congelator running as it is good to have something under your teeth after a 2 hours climbing in the snow. Max watts 150 when both run, but as the room temperature is about -4°C it should be for very short periods with a daily load under 1 kWh/day .
Q1: But on VRM, the voltage stays very low: Yesterday afternoon 24.77 for a 100% SOC and this morning 24.41V for SOC=99.3. These values are not consistent and I fear my settings are wrong though set as required (Ah at C20 for BMV). Or my bats are completely out of order.
When I manage to get there, probably April, I shall test my settings and SOC with electrolite density, but I may have to switch to LiFePo bats a little later.
Q2: Another idea: I tried to have some information about REDOX batteries which could store enough to regulate my power the whole year round (100kWh should do). No answer yet.
Q3: A third idea: I may have to change my panels so I look for wood looking things which could easily cover the whole roof, all spare place being filled with somme look alike materiel or wood. Any idea?
The last two questions are a bit far away from sea-faring devices, But our community is universal isn'tit?
