I’m having trouble getting a stable connection between a 3200W DeWalt petrol inverter generator (DXIG3600) and Must hybrid solar inverter (PV18-5K MPK). I have an off grid solar setup with 48V battery. Most of the time I have no need of the generator but it is for when the batteries run low. When I attach the generator to the house the inverter relays click, lights flicker, but no stable connection occurs. No power draw from the generator and no indicators on the inverter to show power to house or battery.
By accident I discovered that attaching my chainsaw battery charger ~250W directly to the generator while it was also attached to the house seemed to stabilise something and a connection was made, power to house and batteries charging. Occasional flickering of the overload light on the generator but otherwise ok. Unfortunately when the chainsaw batteries charged everything stopped working again.
My current theory is that the generator voltage or frequency are not stable enough for the inverter and that attaching a small load to the generator acts as some sort of ballast.
I’ve tried looking at the inverter settings but I don’t have the original manual and they do not match any of the Must manuals I’ve been able to find online.
I could get a new bigger generator but that costs a lot and no guarantee it will work.
I could get a new inverter but $.
Cheapest option seems to be providing some sort of ballast load. I know it works.
So, any ideas on what might be wrong, how to fix it, or if it can’t be fixed, what is a good ballast load to use?
