Hi
Long time reader, first time poster here. I’m wondering if anyone can help me with planning my set up.
We have a small 2kw enphase M215 microinverter system that works well and delivers power to our main board and feeds surpluses to the grid. We have had the system for about six years. Our house is wired for single phase, 230v / 50hz (we are in New Zealand).
We are looking at adding another 6 kw of PV generation, taking us to 8kw in total. I’m wondering if we can install a string inverter for the new panels and have that feed into our main board in parallel to the generation from the enphase microinverters.
The options we’ve considered are:
A) update the enphase system with more capacity. We won‘t do this as it is cost prohibitive as we basically need to scrap the M215s, envoy and other enphase gear and start again with a new enphase system.
B) rip out the microinverters and feed them in to a new hybrid inverter - either as a second string on a 8kw inverter or running two hybrid inverters in parallel. This isn’t great as it adds cost to our current setup and I haven’t found an 8kw inverter with ESS backup that is acceptable to our grid lines company yet
C) ideally keep the enphase system as it is since its working fine and then add a new string inverter alongside with both systems providing power to the whole board
D) keep the enphase system, but move about 2kw of load to it via a sub panel and then have the new system power the mainboard and the grid.
Is anyone able to advise if option C is possible? Or if not, if option D is a good idea?
