Solar Generator – Final Version and Final Design Updates

The finished large solar generator featured in our DIY How To Build a Solar Generator series. If you are getting ready to follow our video tutorial and build your own solar generator, make sure you watch this video first so you know about the design updates!

In the video below we go over the solar generator features, solar panel kit specs, and our DIY battery bank expansion units. In addition, we show how to upgrade / improve several aspects of the original design including a higher power AC power inverter (3,000 watt continuous, 6,000 watt peak), fully waterproof external switches, mounting improvements, and a better way to store accessories inside the solar generator main case.

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.

How To Build A Solar Generator (3,000 Watt) – Part 1

Note: The original design of this solar generator used a 2,000 watt inverter. This has been upgraded to the new 3,000 watt model in the latest version and several other improvements. Before you build the solar generator following our plans, be sure to watch the new intro and updates video below so you are aware of the changes!

Introduction

I started looking into some of the biggest portable solar generator units on the market, because the idea of a completely silent generator that can run large power loads while never needing gasoline is a really cool concept. Whether you want to run a portable table saw, or go tailgating  / camping where the noise of a standard generator would just be irritating, we will show you step-by-step how to build a weatherproof indoor/ outdoor solar generator!

Solar Generator Build – Quick Links

Part 1 – Component Overview – (current step)
Part 2 – Component Testing

Part 3 – Mounting Internal & External Components
Part 4 – Wiring the Solar Generator
Part 5 – Plexiglass Cover & Design Updates
Part 6 – Solar Panel & Battery Bank Expansion

After seeing what was available, I found myself wanting to design my own solar generator for a number of reasons. For one it will be a lot cheaper, second, I can add several features I wanted to add that were not built in to the manufactured units. Finally, because it will be a really fun project!

By building your own, you will learn all about small off-grid solar setups, and also be able to fix the individual components if you ever have problems with it down the road. You can also easily modify the plans to build a permanent style off grid solar power setup for a cabin or camper.
