I have a 8kW Sunsynk inverter with PV panels and batteries.
I struggled to get a mobile 5.5kW Ryobi generator to connect to the inverter. This was needed when we had extended periods of no grid power and no PV due to rainy or cloudy weather at the same time. Needed to get the batteries charged for nighttime use.
Finally got the generator to work properly.
Here is what I had to do:
1. Connect the generator to the AUX port
2. Connect the AUX port earth to the earth on the GRID port. I do not have the generator connected to a earth spike.
3. Connect earth and neutral together on the generator. This was done by using a 3 point plug with netral connected to eart with a short thick wire inside the plug. I inserted this earth-neutral plug into the second outlet on the generator. Very important is to remove this plug if you use the generator in a mobile fashion to power something like a hand tool etc. Also make sure to mark this plug as a bridge to avoid any potential problems.
4. On AUX menu, tick Gen Input and tick Gen peak shaving and set the shaving value to 80% of your generator capacity. Then set Gen Load OFF to 95% and Gen Load ON to 60% (choose your own values that work for you)
5. On System menu, Work Mode 2, tick Zero Export, AND Limit to load. My generator would disconnect if "Limit to load" was not ticked.
6. On System menu, Work Mode 1, make sure the SOC for the time slot you are running your generator in, is set to 100% and tick GEN box to charge from generator.
7. On Battery menu, make sure the Charge Amps on Batt Type is the same as the Amps in the first block on the second screen under Batt Charge. The first block is the amps for the generator charge and the second block is the amps for the grid charge. Also important is to make sure the charge amps is not set too high. Consider the power drawn from the generator to charge the batteries PLUS the power required to run the load and inverter.
8. Tick Gen Charge, Gen Signal and Signal Island mode on Battery menu under Batt charge.
What a mission to figure all this out, but it is running smoothly now and hopefully this prevents you from the frustrations I had to endure
