I bought a house a couple years ago that already had a ground mount grid tie enphase system installed. My primary desire to upgrade the system is to increase my resiliency during a grid down scenario. Also, the purchase power agreement i have with my coop is garbage, so I might as well use the power I produce rather than selling it at a 90% discount.
My current system has 40 (235 watt) panels with micro inverters and the envoy gateway internet monitoring. I want to upgrade the system as the micro inverters only allow 215 watts to pass though and it has no battery back up.
The options I am contemplating are:
1-Upgrade only the micro inverters to iq8 or iq7s and adding the enphase battery backup. This would increase the power of the system from 8.6 to 9.5kw. This is still relatively small for my needs but i could make it work.
2- Upgrade both the micros and panels to at least 400 watt which would make the system 16kw and be plenty powerful for my needs. Include the enphase battery backup but start smaller as the system gets expensive fast.
3- Add a completely new system to my roof. I would still like to make it a hybrid system that would use power from the system before the grid. I don't have to use enphase at this point and can be more flexible and get more bang for the buck.
Does anyone have any strong feelings either way about these options?
Appreciate the input.
