Solar Generator – Battery Bank & Solar Panel Expansion

This is an update to our DIY How To series on How to Build a Large Solar Generator.   In this follow up post, I will show you how we can use the quick connects designed into our solar generator to expand both the solar charging capacity, as well as the battery bank for increased run times.

A lot of the feedback was asking how to expand the solar generator to an even bigger capacity system. When I designed the base unit, I wanted it to be very easily expandable using quick connects. There are two areas where we can easily do that with our system:

DIY Solar Generator – Plexiglass Cover and Improvements

In this update to our DIY Solar Generator how-to series, I am going to show you how to build an acrylic Plexiglass cover for the inside of the solar generator, so that we can store things like jumper cables inside the case without worry about shorting out or damaging any of our wiring connections. I will also show you some updates and improvements that I have made since the original videos, including a way to automatically disconnect the solar charger from the battery when the solar panels are unplugged. This will keep the solar charger from slowly running down the battery while in storage, without having to remember to turn on or off a disconnect switch. I will also show you a better solution I have found for the solar cable wire including heavier gauge cable, for less cost, and a built in cord wrap.

How To Build a Large Solar Generator – Part 2 – Component Testing

This is part two in our series of posts on how to build your own large (2,000 Watt, 4,000W Peak) solar generator.

Testing the Components of Your Solar Generator

Before we start mounting all the various electronic components into the Pelican case for our solar Generator, it is a good idea to make sure everything is working correctly.  We definitely would not want to discover we have a defective invertor only after mounting it and wiring everything else up around it.
