I have 2 Deye 8k inverters in a fully off grid house. I have a propane generator tied to the grid input and a smart load tied to the gen input for my EV charger. But I have never been able to get the generator to turn on. Even if it’s running it will show 1watt coming from “the grid” but it...

I currently have 6 Rosen powerwalls (48V, 200Ah), though 1 is not working (but thats for another post, and it is now offline). I only visit this property once every few weeks, and it seems like every time I look at the SOC of the 5 individual batteries, some number of them will not be...

I currently am running my house on 40 panels using 2 inverters, each with 2 MPPTs as shown in the image below. They are all roof mounted and facing south with no more room on the roof. I purchased a total of 45 panels (5 extras), and now I'm thinking it might be nice to add those extras to the...

Something interesting happening on my deye inverters (identical to SolArk 8k).... I have 2x 8kw inverters hooked up in parallel, with 17kw of panels, and 60kwh of batteries. We are not connected to the Grid at all. The system seems to be working fine, but when I disconnect all the batteries...

Need a quick response here as I'm having plumber hook up water heaters today. My initial plan was to have an electric tank water heater to pre-heat my water using excess solar (I have a 16kw system). My plan was to then have the output of the electric WH to go to the inlet of a propane on...

So I am new to this, and while I think I have the math down, I definitely would like a double check. I have 2 Deye 12k inverters (same as Sol-Ark 12k). I'm hooking up 40 panels. Panels have the following characteristics. Pmax = 435W Vmp = 72.9V Imp = 5.97 A Voc = 85.6V Isc = 6.43A Each...

I'm looking at using a rail-less direct roof mount on my standing seam metal roof. My only concern is whether or not it will get sufficient airflow underneath the panels and if that even matters or not? I'm located in Oklahoma and it can get pretty hot there (Typical summer temps in the high...

In order to help manage electrical use in my off grid, I was thinking about what I can do with home automation.... For example, when battery goes below 60%, the mini splits will go to "eco mode" and adjust temp accordingly, and when battery gets to 25%, AC shuts off (or some other cutoffs)...

I'm sure this has been answered somewhere, but I just can't find it. I'm looking at an off-grid install, using 2x8k hybrid inverters. According to the specs, each inverter has 2 MPP's and it says the max number of strings per MPP tracker = 2+2. The input voltage range is 100V-500V, and MPPT...

I'm trying to get my head around all this, so would appreciate some help.... I'm looking at an offgrid situation and I'm just trying to understand how power will flow.... So I'll need about an 11kW system for my needs... so lets say 50x300 watt panels. I'll also planning on about 8, 100aH 48V...

I'm building a 2400 sqft cabin in central OK, and to run electricity will be fairly expensive ($20k+). The cabin will have about 1400 sqft of south facing roof at a 5/12 pitch which would not be shaded. I'm considering whether it is feasible to go solar. My biggest concern is running the AC...
