My new AMG 24 V 6K watt inverter will not start a 1500 w micro wave. Also will not run a 1/2" drill.
Does find on pure restive loads. Any thoughts on how I can correct this?
Are you running it in 120v output or 240v output mode?
4-0 copper cables 6- 100ah batteries in series/parallel

My AMG will not run a 20 year old microwave . Look like the old rev 11.3 control board is no longer available for repair . I added 6 more capacitors to run the old microwave and use 4/0 welding cables .
What value of cap did you use. Did you put in series with the output?
@danny-hoppers These would be DC bus capacitors on the mainboard / battery DC lines. PJ uses (or at least used to use!) 10,000uF caps there. I don't think these have a significant affect on the inverter running loads, though they should improve FET lifetime.
Your battery capacity should be good...and 4/0 cables is way bigger than what's inside the inverter!
Does it beep and light the red LED (i.e. "shut down"), or just "can't run the load"?
If the former, likely it's the output current sense tripping the system. Which...can be bypassed (or at least modified).
It beeps and lights the red LED
@danny-hoppers OK, so it's doing an "overcurrent trip".
These tiny switches control load resistors on the output current sense...try flipping a couple more of these into the "on" position. (This also affects the "charge current", but I presume you are not using AC input / charge.)
At least in my experience, this trip threshold is usually set too low. Worst case, it'll blow FETs--but then again, that's what PJs are known for...
Thanks, I will try that( probably be tomorrow) and get back with you.
Well Sid I am going to change my story! Thought I would try to start micro before I moved any dip switches. Wouldn't start micro, no alarm or light, micro would just grunt a bit!
Any thoughts on what I can try for this ?
@danny-hoppers Hmm. Might be tripping based on the "protect" circuit...but I would think that that should give an error light.
Trying to figure out these beasts is rather difficult!
Maybe this will help. I tried to run a 1/2 drill. The motor would run a few rpm and stop. It would keep cycling like this. After 3 or 4 cycles the drill would come up to full speed.
My AMG Powerjack also have problem running inductive load when wire as split-phase 240 vAC . I later re-wire the transformer inside the case to make it run inductive load better in split-phase 240 vAC. Can you run a resistive load without problem ?
