3360 Watt Solar Generator Build - BIG Portable Power

Updated: Aug 5, 2021

So, living through hurricanes can be quite uncomfortable not only during the storm, but after as well if power is lost. I decided to build my own Solar Generator (see my YouTube video) https://youtu.be/C_j97qyvzDU because I couldn't find one available on the retail market that could provide the capacity I needed to run a 5000BTU window air conditioner overnight. When dealing with everything associated with the aftermath of a big storm, solid rest (not sweating and sticking to your sheets) is invaluable!


The first step was to purchase battery cells and build my own 12v 280Ah LifePo4 battery so I had enough power to run the AC (or an entire living room full of electronics) for a full day or night. Then I properly sized all of the components in my design for safety/functionality, bought a big roll-around tool box, bought all of the components and got to work. The outcome was beyond my expectations.


Once fully charged (via solar panels or AC charger), I can run my AC all night keeping one room in my home cool so everyone can escape the heat for a while. I can run an entire living room (65" LED TV, Cable Modem, Wireless Router, X-Box, Laptop(s), and of course a fan) for 12+ hours. Party! I can boil water with a portable electric kettle to cook or sanitize for drinking. I can cook using a pressure cooker, rice cooker, etc. If I were in a cold climate, I could run a small electric heater for comfort.


The bottom line is that this generator was relatively easy to build (if you are in any way handy), provides a ton of power and functionality, and is about the third of the cost of a retail unit of comparable capacity. If you are interested in building one, watch my YouTube video https://youtu.be/C_j97qyvzDU and give it a shot! I promise you won't be sorry!
