Was this a do it yourself design or kit or pro install?
That’s an older picture when I just had 300ah. I’ve since taken over the smaller cabinet next to it for two more. In the cloudy PNW, 300ah wasn’t quite enough as we use a lot of power with induction cooktop, tea kettle, TV, hair driers, etc. There’s 500w of solar on the roof and another 100w on a portable panel I can move around.
Yes, the blue box in the outside storage compartment is the Victron hybrid inverter/converter/charger. I took out the converter and transfer switch that came with the trailer so the Victron does all of the power management and talks with the Victron Solar controller and battery monitor.
Because of the Victron, I set it up so the rest of the trailer just thinks it’s plugged into shore power. That means all the outlets are live all the time. You just have to keep the overall load under the 3000w the Victron can supply.
I did this myself (I’m an electrical engineer). AMSolar has kits and superb support for those interested. I, however, pieced this install together myself from various sources to save a few bucks.
To answer the question of too much weight on one side, I haven’t noticed any problems. Lithium batteries are about half the weight of lead acid or AGM, about 31 lbs each. They are only about 18” off the centerline of the trailer so that helps. Lithium also means you can mount them inside (no outgassing) and at any orientation, something I couldn’t do with lead acid.
