I've lived off grid for 6 years with few problems with my 10kw genset feeding power to my SW 4048. Now, I've got problems
The system now has grid power available...cheaper than diesel for charging batteries.
The problem is this: when grid power is applied (it doesn't matter, ac1 or ac2, things charge and bypass to loads just fine...when you remove the power supply (cut-off switch) the inverter doesn't immediately revert to inverting, it chugs along at minimum cut off voltage ac in charge/bypass mode. At this point there is NO power supplied (cut off switch OFF), yet the inverter will not invert.
When shutting off the generator via the inverter there's a clunk of a relay disengaging from the source. However, if you start the generator (or utility supply it seems) and supply power to the inverter it will charge/bypass as per owner's manual specifications...but when you remove that source it won't disengage as the manual suggests it should (in the testing mode section...relay will disengage and begin inverting immediately).
My work-around is to shut off the cut off switch, shut the inverter to OFF position then immediately cycle to ON. This shuts off the whole house but only for a few seconds...you hear the relays activating when doing this. The inverter shutting down must disengage any incoming power via the relays.
Any thoughts? I've tried changing the ac2 to ac1, the only difference is the drop of supplied power is much shorter on ac1.
Thanks for any thoughts
