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 Battery rack is awesome.

I purchased this rack to replace my regular 19 inch rack. This is much more heavy duty. It looks much better also.

Easy to Install some improvements needed

These inverters are all in one you can do up to 8,000 Watts 500 VOC which means you could easily run 20 400 watt solar panels from one inverter! The downside on the PV input power from the solar panels is a tiny set screw that holds the wires in. Rebranded inverters come with a simple Plug and Play setup there are many versions from the same manufacturer. Names like Rich solar, SunPower and Sungold Power to name a few this is the most inexpensive rebranded name of them all so it's the best one minus the connectors as I mentioned above. Also it would be nice if there was a built-in software user bypass other than the battery bypass. So if you're running these in a series you could simply bypass the voltage output so that the other inverters can run independently if you have a problem or it quits working, unfortunately this is not the case. These were sold to me as off-grid so you have to consider there's going to be dust more than a normal neighborhood . This brings me to the inverter filters hold on each side at the top for the intake air flow. The filters are a cheap sponge like plastic material you can wash them out and let them dry I find myself cleaning them weekly. Dust still gets inside of the machines this is huge as you don't want dust in the electronics. The app for this inverter is offered under two different names. Even after talking to customer support they came back to the same conclusion the app is garbage. It lets you know the basics like what is charging and…
