Kinda similar set-up here.....1600W of solar and 840Ah of Lithium batteries. I used the Lion Energy and love them, 30% lighter than BB and also a smaller footprint which allowed me to get 8 with room for 2 more in the same space that would only accommodate 7 BBs. If I was doing this again knowing what I know I might do the DIY cells but since the batteries were going at the foot of the bed I decided to go with a drop-in with integrated BMS.
Until yesterday I was running a Victron 150/100 with the panels, that was pretty much maxing out the Solar controller and we still had the 2001 Xantrex Fredom 458 (MSW) inverter. This actually worked pretty good even with a residential refrigerator and built-in wine cooler but..............it wasn't good enough
Over the last few days we converted the battery bank to 24V (See Picture) which meant adding 24-12V conversion, I wanted to have real time visibility to everything n the system so we decided to go with Victron gear. The first thing we needed was 2 24-12V converter to handle the large 12V load potential with the leveling and slide-out system, and also added (2) 12-24V DC-DC converter chargers to handle alternator charging while on the road.
For power we used (2) Victron 24/3000 multiples inverter chargers configured for split phase operation which gives us the ability to run a 240V device in the future (Mini-split AC unit)
and added a 240 breaker in a subpanel and ran wire to future location of condenser unit.
Everything is wired through 2 Victron Lynx bus bar/fuse systems for protection and efficiency.
The results are nothing short of amazing.....today I was running one of the rooftop AC units AND the hot water heater at the same time no issues
The screenshot was with the AC unit running with the water heater off.
I'm sure something like this will be your next step and thought I'd share....good luck with your next steps.
