Becareful with the EG4s and AGMs. Last I checked the EG4s couldn't be

some of the heavier plated AGM. Surrette and Full river AGMs need to be

I was definitely moving to the LFP camp for off grid for all the same

are nice features available with these cyber enhanced systems, but the
cost in reliability makes being energy independent off the grid hard to

fortress is making improvements to their firmware for sure. The fortress envy 12 has generator warmup/cool down which is a really important feature IMO. The eg4 not. Nor does the Deye sol ark. JayOn Feb 16, 2024, at 8:48 PM, Chris Sparadeo via RE-wrenches wrote:Howie,The EG4 18K and the

I took a quick look at the Discover AES battery specifications you

when the battery is turned ON, but doing nothing? In my experience

We gave EG4 and Signature another chance after promises from their dealer

Hi All,
I've searched the archives for info pertaining to EG4 inverters and
batteries. The comments have been mostly positive. I have stayed away from

Just wanted to make a correction on the EG418kPV of a statement made

The EG4 18kPV does have frequency shift based AC Coupling. The

Hi all,
Does anyone have any experience with EG4 products? I am doing an off-grid
consultation for someone who plans on getting EG4 inverter and lithium
batteries. The equipment seems so cheap, yet appears to be somewhat legit.
They do at least have UL1741 listing. But their 6500w
