I had ordered most of my System from Signature Solar, all went well until the Shipping. It was a Complete Disaster. So when I wanted to increase my Battery Pack I went with Shop Solar. Everything went Perfect, especially the Shipping, it was even better than I had asked for. Wish I'd went Shop Solar from the beginning..
I have 2 - EG4 6000W inverters along with 3 - 5.1KW EG4 batteries and 12 - 400W solar panels. I purchased this as a kit from SSK. The kit came with ALMOST everything I needed. I purchased one panel, then added a second panel a few months later. I suggested that, when providing the inverter that a USB to Serial adapter be included for firmware updates. The second panel I ordered came with the adapter. They actually listened to my suggestion and implemented it. Can't ask for much more than that.
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…
