As we have been simply getting began, we had a fundamental RV battery setup. As a result of AGM and Lithium batteries have been so costly once we set out in early 2018, we settled on two commonplace deep-cycle flooded lead-acid batteries. 

We had 200 watts of photo voltaic panels and a 600-watt inverter tied into the RV home electrical system.

However we relied on a easy show display screen on our inverter to gauge our battery’s voltage. Whereas this can be a respectable, primitive type of maintaining monitor of battery voltage, it didn’t present us with an correct studying of our battery’s capability, particularly since we’d later discover out that we had wired our inverter incorrectly!

Then we met somebody who utterly revolutionized the way in which we checked out battery energy and the significance of getting a accurately put in RV battery monitor to report an correct studying of our battery’s capability at any given time limit.

Since that day, we’ve develop into energy junkies in that we all the time put our electrical system first, our water system second and all the pieces else third in our RV.
