Hi, I currently have 6.6kW of panels with a 5kW Fronius Primo inverter that is ~5 years old and still working well.
Where I'm located has a 5kW export limit to the grid for single phase. Voc of each of the 2 strings is 480V and 400V
I'll soon have ~15kWh of batteries (48V LiFePO4 setup) to incorporate into this system. Am I better to:
1. Have a sparky completely replace the Fronius inverter with a hybrid (like a Deye inverter)?
2. Keep the Fronius, but have a sparky install a transfer switch and some other off-grid inverter/charger?
One problem is that most electricians here don't want to install a inverter that I supply (and get for a great price) and prefer to sell me something at a very marked up price or completely replace the system with some brand(s) they prefer.
