This is our first time this year off grid with our new lithium set up so far i am impressed, we have 4 x 200 A/H victron batteries with all the assorted BMS and various relays for Solar and /Alternators,. 4 x 200 watt solar panels on the coachroof and 4x 100 watts on the wheelhouse roof, the latter were already there from the previous install, , all monitored and networked with a colour control.
We are quite heavy users with 2 freezers ,fridge, computers running virtually all the time , large screen tv etc, all the gadgets and last night it went down to 89 percent read at 06:00 and by 07:00 back up to 100 percent purely on solar , early days but i believe the investment will pay off.
We replaced our Rolls lead acids as they were 11 years old having given good service were losing charge quite dramatically. and having to run the generator for a few hours daily.
