Generator on GEN or GRID

I am looking at installing the 12kW three-phase SunSynk hybrid inverter with 20kWh SunSynk batteries and 5KW panels and was hoping someone on the forum would be able to help me answer the following two questions:


  1. I understand that the maximum load on the inverter would be 6kW per phase. I assume that this maximum would only apply to the essential load when the grid is up and that we would be able to run the normal phase maximum on non-essential loads whilst the grid is up. Is that correct?

  2. I have a 50kVa generator on the premises that is currently connected to the DB with a normal automatic transfer switch. Would it be advisable to connect the generator to the GEN port of the inverter or would it be best to keep it connected to GRID as-is (ie connect the load currently coming into the DB after the ATS to the inverter's GRID)? I would like to ensure that we are able to run all non-essentials loads using the generator during loadshedding (only if needs be) and wanted to check if the non-essential load would be limited to 6kW per phase if the generator is connected to the GEN port of the inverter. If we leave the generator as-is (ie between the utility supply and the inverter's GRID port) I assume that there would be no limitation on the non-essential load (as per question 1 above). Is that correct?

Thanks very much for your assistance!

Thanks very much for the reply, Peter.


That makes perfect sense and addresses my concerns. I think I'll connect the generator to the GRID side.


All the best
