Battery work for RV solar and inverter systems

Solar panels and inverters are only as good as the batteries behind them.

Roof solar only helps if the batteries and charge controller are set up for it.

Florida gets a lot of sun, and plenty of RV owners add solar panels and an inverter to run more off the batteries. The battery bank is the center of that system. When the bank is undersized, wired poorly or set up with the wrong charge settings, the whole system disappoints.

What we do

  • Battery bank replacement and upgrades, often from lead-acid to lithium, sized to how much you actually use.
  • Charge controller settings. Matching the solar controller's profile to the battery type. A controller set for flooded batteries can overcharge AGM or undercharge lithium.
  • Inverter and inverter-charger battery connections. Correct cable size, short runs, proper fusing and tight lugs. Inverters draw a lot of current, and loose or undersized cables get hot.
  • Battery monitors. A shunt-based monitor tells you real state of charge, which voltage alone can't.

What we don't do

We are a battery company. We don't do roof penetrations or install new solar panels. If your panels or roof wiring need work, we will tell you, and you can bring in a solar installer. We will make sure the battery side is ready for it.

Questions we get about this

Can my solar keep up with a residential fridge?

It depends on panel wattage, sun hours, shading, the fridge and the battery bank. We can help you estimate it, but it is very setup-specific.

Do I need lithium for solar?

No, but lithium charges efficiently and you can use more of its capacity, which makes the most of limited solar.

Dead batteries at the campsite? Stuck on the shoulder?

Tell us where the RV is, anywhere in Florida. We bring the battery and install it there.
