It’s time to inform the reality about RV photo voltaic and lithium batteries. Not that they aren’t nice to have. It’s simply that too many RVers have been talked into getting photo voltaic/lithium packages by unreasonable claims by RV salespeople who simply don’t perceive the boundaries of the expertise.

Let me be very clear: We’ve been utilizing RV photo voltaic and lithium batteries since 2015. Jen and I like RV photo voltaic and lithium batteries. We wouldn’t have an RV with no strong system and, certainly, we simply did a serious improve of the RV photo voltaic package deal and lithium battery financial institution on our Keystone Arcadie fifth wheel.

However the secret’s having sufficient RV photo voltaic and lithium to do what the salespeople promise.

This week, we speak to 2 consultants as we discover the capabilities of our new system and find out about battery draw and what’s cheap and never cheap to anticipate from it.

The first thing people thinking about RV solar and lithium need to know is that you need to know if that the more you have, the more you can do with it in terms of off-the-grid camping.

A 200-watt RV solar package with a single lithium 100 amp hour battery isn’t going to make the huge difference you often hear from RV salespeople.

And the 1,000 watt inverter systems that come with most RVs to convert that energy that solar puts in the batteries is woefully inadequate if you want to run things like a microwave, a hair dryer or an air conditioner.

When we bought our Arcadia this spring, we bought a package that had 600 watts of RV solar and 200 amp hours of lithium, with a 3,000-watt inverter.

That’s a very respectable system. It will even fire up one of our air conditioners equipped with a safe start to minimize the huge power bite the compressor takes when the AC unit starts out. Fully charged, it will run that air conditioner for two hours or so, depending on how hot it is outside and the humidity it needs to remove from the coach.

But we wanted more. Our upgraded system has four 300-watt Keystone Solarflex panels providing a total of 1,200 watts of energy that charge two Dragonfly Energy Gamechanger 3.0 lithium batteries that each have a capacity of 270 amp hours. That’s a total of 540 amp hours. Dragonfly is the parent company of Battleborn Batteries.

For us, this is the sweet spot for our boondocking and off the grid camping. The system will let us run the AC for about six hours. Maybe a bit longer if we don’t try to turn our RV into an ice cooler.

In separate interviews, the two discuss all the ins and outs of RV solar and lithium, including;

  • The limits of solar panels when the sun isn’t shining.
  • Why solar should be wired in series instead of parallel.
  • The importance of knowing how much power various RV appliances draw
  • How to monitor power usage.
  • The expense of solar and lithium packages (think thousands of dollars, not hundreds)

But the bottom line is before making your solar and lithium choices, educate yourself.
