Thank you for your advice.
The system has now been installed. They installed 2 x Huawei 5KW battery ready (Hybrid) inverters.
What I did not realise is that these are single phase inverters. They have installed one inverter on each phase. Leaving the 3rd phase not connected to the Solar.
They are saying this is OK because our electric company will be fitting a Net meter and so any electricity consumed will be offset by electricity generated during daylight hours if we are in surplus. Does that sound correct?
The second reason they said they for giving us two single phase inverters was that the technology for 3 phase hybrid inverters is still in development and is not readily available. Is this true?
They are telling me our system setup is as good as one three phase hybrid inverter if there was one?
Thank you for your time.
