Our new solar/inverter power system

Some expressed interest in our system on another thread. Here it is.


Not a great roof shot but here is a progress shot. You can walk the entire roof for cleaning and maintenance.



Combiner box with circuit breakers for each series connected panels. Panels are 200w arranged in 3 in series 4 groups. approximately 100v @24v.




The batteries are installed under the stairs on a sliding tray. I relocated the basement wall to add space for the equipment and additional storage. (see picture below)





BMS unit for battery.





Pretty much complete. The blue tape is that stock basement wall line. You can see how much wasted space existed behind the stock basement wall to hide the waste pipe.



We have a couple weeks now on the road and everything has been great. The 4000 watt inverter will run everything we need including 2 big loads like air conditioner and microwave or water heater at the same time. The solar has been generating 10-16kwh per day mainly limited by the solar charger tapering off as the battery is full often. I could easily increase this by 30% with tilting panels. Not needing more power though as we try and avoid hot weather and the need to run the a/c a lot.

Cheers :)

    I hope you’ll provide some more information on your setup as I’m interested. I’m guessing 12x 40 cell 200W panels for 2400w. Is the battery bank 24V and there is a 24 to 12V converter?


    Yes, (12) x 200 watt panels. Link

    The battery bank is (24) CALB 3.2v @100Ah cells configured 3p/8s for a 24v battery @ 300Ah with a Daly 200AH @24v BMS.

    There are (2) Victron Orion 24 to 12v converters in parallel to handle the house circuits, electric jacks, slides etc..

  • work2much, “Color me impressed” A beautiful set-up! memtb
  • What a clean, good looking installation! This reproves the theory of RV solar.
