We like the warranty. Haven't put the batteries into use yet, so we can't report on their performance.

A much needed battery bank addition

With my other 2 batteries of this type, I have high hopes that this will put me over the top to cover my off grid electrical needs.

Best Portable System Built for Cheap & Robust Reliability!

The system was exactly what I was looking for. I built this portable 5 thousand watt system with the intention of using it off the grid in case I had to use any battery powered tools or power saw in an Emergency! This fit my budget and my hazardous type work environment which was in the woods and dessert especially during wet seasons and extreme cold winters. This is my second system. The first system is still humming along. I even dropped it in a 15ft ravine and it still powered up with a huge dent in it. Talk about reliability! EG4 quality is Damm incredible!

Great battery

After much research this battery had a great rating and was very affordable. After purchasing 6 of them and using them for several months I am very pleased. They have worked well and I couldn’t be happier.

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Shop Solar team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Shop Solar.

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Shop Solar on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!
