    First Draft: New RV Power System Diagram

    Hello there. I'm upgrading to a larger full time class-c RV from my little Starcraft TT, and so it's time to build a new, bigger solar power system. This is my first initial draft of what I have in mind. Still need to measure length of all the wire runs to determine wire gauges. But in the mean...

    What is normal behavior for an inverter charger?

    I have the Renogy 2000Watt Inverter Charger and it's my first time using an inverter charger. I'm confused by its behavior, but maybe this is normal: When I plug into shore power, my batteries are charged to 100% by the inverter charger, but then after reaching 100% charge, the inverter charger...

    New setup: How do I know SOC of batteries?

    Hey there. I just hooked up a new system with two 170ah lifepo4 batteries (12v) with the Victron SmartShunt. The SmartShunt wants me to tell it the state of charge of the two batteries. How do I determine the SOC? Is it really just a matter of looking at the battery voltage the smartshunt...

    Wiring Diagram: How did I do?

    Hi! I bought my first camper and intend to do some off the grid camping with it. Other than working on my car, I knew very little about electrical systems before this. I've been doing a bunch of research and wanted to see how far it got me in terms of planning out my own system. Today I took a...

    PWM Controller Recommendation for Mismatched Panel System?

    Hello! I am outfitting a tiny camper with solar panels, a 170 Ah 12v lithium battery, and a 2000w inverter charger so I can live/work off the grid for a while. Due to space constraints and the presence of other equipment on the roof, I'm attempting to maximize power generation by using a...
