There are a few other threads discussing this mildly off-topic topic. But I suppose the same type of people that want to be energy independent might want some food security as well. We haven't seen nationwide or global energy shortages nearly as profound as the empty shelves of early 2020 (you...
I was doing some system maintenance today and noticed one on my charge controllers shows 3316 kWh. That's 3.3 MEGAWATTS! I installed that one with 2kw of panels in August of 2021. As I built and maintained powerplants that output gigawatt/hours in a past life, I am simultaneously unimpressed...
Fitting day for the 1 year anniversary of the MPPT test.
The goal of said test was to determine with lazy scientific methodology if there was an advantage to allowing the turbine to gain inertia without the constant load of the 24v applied voltage but rather to let the charge controller...
I stumbled across this paper a couple years ago and then couldn't find it again. Interesting read.

I think the title sums it up well. But to clarify, I don't care about NEC, rules, regulations, or UL listing. I'm looking for reasonable alternative solutions for a weather resistant metal box to house a small system.
I am electrifying three small B&B type cottages.
If you can relate, what...
I'm not sure whether this belongs in beginners or advanced. How's that for a spectrum?
My question being: Is there a reasonable expectation that panels in an off-grid application are ever in a VOC situation with an MPPT charger?
Non proprietary hardware and software allows for infinite modification possibilities.
Fireproof heavy duty steel enclosure eliminates need for fuses, breakers, or other pesky safety devices.
Plenty of room for system expansion and storage of volatile fuels and hidden firearms.
Meaty grab...
This has been a nagging question in my mind for some months and I've yet to get a satisfactory answer.
Many in my circles are buying solar generators for backup emergency power. However, the lithium batteries in these units are suppose to be stored at less than 50% charge. Is it then the case...
I have this AIO installed in a small system feeding an unused, stationary RV. I checked the system after several months and noticed there was no screen. After checking the batteries 2- 12v/220a LiPo4 in series, I realized the batteries were low (one at 11.75 and one @ 12.4). I disconnected the...
