In this video, I go over in detail all the components and wiring of my complete boondocking power system including solar panels, controller, batteries, charge converter, inverter and all the fuses and switches.
Hopefully, this will be of help to folks who are trying to understand my complete system. Up until now, it’s been a series of install posts and videos which can lead to confusion of how everything works together. Especially since I have upgraded and changed things as I’ve expanded the off-grid systems.
Disclaimer: Working with electricity can be dangerous. Performing the modifications detailed in this video may void your warranty. The following is for educational and entertainment purposes only and should not be taken as instructional. If you decide to do the same modifications I’ve done then research and beware of the risks involved. I accept no liability. You have been warned! – Ray
