I have a EG4 3kw inverter/charge controller. From my reading, it dynamically creates a ground-neutral bond when not receiving power on its AC input (i.e. the grid / generator input). EG4's assumption seems to be that with grid supplied power, the grid supplies the ground-neutral bond, and for...

I'm building an off-grid solar system for an equipment garage. Its rural, and the county I'm in does not have electrical inspections. Code compliance is not an concern, but safety is. This video got me thinking about the value of my batteries and inverter being portable. I plan to cut up an...

I ordered a pallet of Hyundai 305w panels (HiA-S305HG). My first project will use a dozen of them, and I think I need to split them into two strings of 6 serial panels to stay under the 500v limit of the EG4 aio controller I'm looking at. From the spec sheet, VOC is 39.42 Temperature...

I'm in south central Kansas. Abnormally cold would be lows of -5 and highs in the teens. It got that cold last week and the news said it was the coldest its been in a couple years. It was a total of 5 days where the high temp didn't exceed freezing. So I'm wanting to plan for that temp...

I understand that AC rated switches shouldn't be used for DC, because of the difficulties extinuishing the arc with DC current. Larger air gaps are required, and if the switch fails to extinguish the arc it gets ugly. It occurs to me that outdoor disconnects used for air conditioners and other...

? I've been reading a lot of threads on here for the last few months, and I think I have my controller settings figured out, but want to run this by you guys. I have a LiTime 12v 100ah battery ordered, the manual recommends: I have a HQST charge controller that does not have a LiFePO4 setting...

I have a few small solar sytems for off grid projects. My batteries have low temp protection, but if its too cold for too long, the batteries refuse to charge lets them run down. I'd rather not waste power heating the batteries through the night or if its overcast and can't charge anyway. So...
