As far as I can tell, it is not an inverter generator. By the battery dead, I mean it is below the voltage that the renogy inverter will use the battery. The battery is good, as it charged from the solar panels. I am using the 120v from the generator, into the ac input of the renogy (yes, it...

One other thing that probably is not relqvent, the battery is lithium

I have a very simple setup for my off-grid camper setup. Renogy 3500w inverter with 3 230w panels in series and a single 48v server rack battery. When I set up the system at my house (no panels), I was able to charge the battery fine from the grid. I finally got the camper to my property...

It is a standing seam metal roof. I’m planning on 2 rows of panels eventually, the first row (closest to the edge) will be flat on the roof, and the second will be angled about 30 degrees (so as to not be blocked by the first row). Strings will be separate parallel circuits such that the back...

As part of my project I will be mounting panels to a metal roof. I’ve seen videos of rv installs with no drilling (in fact I have done this on my OFFGRID camper setup - camper is stationary on a piece of property, so I don’t need to worry about them coming off going down the road). The...

This has me a bit confused (newbie here). I’m planning on a small system for my workshop. I want to use solar and battery when it is available and have the grid for power (charge batteries, provide power) when not. In this type of setup, would the grid see any back feed (I do already have a...

Planning on doing a small off grid project since the new eg4 battery is what I’ve been looking for. The battery and inverter will be in an insulated but unseated building. I realize that if the temp is below the spec of -4 Fahrenheit, I won’t be able to draw power, but what happens if I’d the...

I'm building a new shop and want to make it off grid. I have a 120V inverter already, but want to be able to run some small 240V loads (<30amps at a time). I'm wondering if i can feed the 120 into an auto transformer and take the 240 out and run that into the breaker panel the same way a grid...
