While not a tractor topic, I consider TBN to be a superb brain trust.
Last year in a feeble attempt to improve my offgrid setup (10kw PV, 3 MX60s, 4 FX3048, x240, Mate3), I decided to upgrade my generator.
Old Genset : 24kw, New Holland Shanghai diesel engine, Monicom control panel, 25 gal tank. Provided good service almost 7 years and still running when I sold it.
New Genset: 24kw, Yangdong Diesel engine, Deep Sea 7220 control panel, 100 gallon tank.
Smaller backup Genset: Home Depot off the shelf, gas powered Ridgid 8000.
When hooked up, my new Genset always has an imbalance between L1 / L2.
My observations:
There is 0 imbalance with Genset running but not hooked up.
Imbalance registers immediately once connected at the DS7220 readout and fluke meter readings anywhere from cable connection to Outback buses.
Imbalance is usually 5 volts at beginning, but increases over time, highest observed was over 30.
Cable to Outback will heat up and has damaged connection.
Breaker to X240 will trip, but not always. I added fan to x240 but no help.
Microwave and washing machine control boards don't like and error out.
Hook up Variations:
My cable into Outback is same that has been in service over 7 years. 10-4 with connector on one end thru house type watt meter to outback ACIn buses and neutral. Initially the connector was 30 twist lock type for connection into old Genset or Ridgid but I replaced with 50amp plug. I have a short connector conversion to hook into the Ridgid.
Have tested with ground connected and not connected at Outback without effect.
Same cable hooked into Ridgid generator, same Mate settings shows no imbalance, either initially or after time.
Various Generator connections tested.
Cable to generator main breaker (200amp)
Cable to generator 50 amp socket with ground Cable to generator 50 amp socket without ground
Note - generator is not grounded separately, neither is Ridgid nor old Genset.
Other tests: I have disconnected all loads from the AC side of Outback by turning off breakers in main distribution panel to house.
I have have turned off inverter output breakers individually until all were off
I have shut down individual inverters until just 1-2phase Master (port 1)is on.
I have tried various mate settings for generator from min to max and some at zero.
I have spent time with on phone with Outback Tech support and couldn't resolve anything.
Generator guy checked and couldn't find anything wrong with Genset. At this point he suspects a grounding issue.
I have replaced 1 fx3048. Mate3 was also replaced by Outback.
There are no error messages.
So, to say I am at a loss would be an understatement. What else can I check, test, look to verify is correct? Not only is this a PITA, but a safety hazard due to the heat issue.
Any and all suggestions welcome.
