- BUT -- I would have expected the inverter to simply go into protect mode if the load was too much. This may be a deal breaker if the inverter isn't intelligent enough to shut itself down under an excessive load. Thoughts? Experiences?
One thing a PJ definitely isn't.....is smart. It's only got "power monitoring" on one leg (L1-N typically)...and nobody knows when it'll actually trip, as there's no indication of monitoring.
Purely resistive loads actually are the easiest loads to run...it's those inductive and surge loads that are real troublemakers!
When I turned on the inverter, it made a pretty notable sound but seemed stable. I ran indoors to observe the LED light (the inverter was mounted in the "belly box" storage area behind the 5th wheel). The LED light was quite dim.
I mean, I can't say a "notable sound" is unusual for a PJ inverter, given that the FET drive is so lopsided and mismatched. A loud transformer buzz is quite normal...but a low output voltage isn't.
Sid -- I just checked and the "E" input terminal is at the same potential as the chassis ground stud -- so that's something at least. Should not cause a problem -- just thought I'd mention it.
was going to respond to this earlier, but a bit of time passed 😉. This is expected behavior--"E" terminals are the chassis ground terminals. They should not be shorted to any of the other AC output/input terminals, as well as the DC inputs.
This may be a deal breaker if the inverter isn't intelligent enough to shut itself down under an excessive load.
I had an 8k non amg PowerJack inverter shut down yesterday due to low battery SOC of 19 percent in a 544ah 24-volt Lischen build battery.....the snow is about 2 foot deep and the last 12 inches on Thursday buried all things deeper...
the PowerJack did shut down but will not be adequate to protect the battery...
I think the PowerJack manufacturer keep changing things so who knows....
normally I keep the batteries 80 to 99 percent SOC but the snow and animal caretaking kept me a bit too busy.... so found the inverter squealing and shut down on SATURDAY...
i hooked the 544ah battery to a Riden 6018 via a redundant 544ah battery and separate PowerJack non amg 6k lf psw sp inverter and brought it back up to 32 percent SOC yesterday...will do more later today...
i highly recommend the Riden 6018 bench power supply for battery charging....mine works great...i had 400 watts pushing into it no problem in my off-grid whole house solar pv build...
cheers, 😎
I do not use the charge function on any PowerJack inverter and do not connect any to the electrical grid monopoly.
all is done off-grid with solar PV panels....although i can rob some stored electric from a reduntant pv charged battery when needed via a different PowerJack inverter...
separate battery charging is better in my opinion....
let the PowerJack be an inverter and nothing more....

I use the Riden 6018 for bench testing the Powerjack mainboard and FETs before pushing thr Powerjack power switch for the first time . I then connect the rev 11.3 control board and use the Riden 6018 to test to see how many green LED light up after pushing the Powerjack power switch . The low amp output from the Riden 6018 will not damage the control board but will test the LF driver .
