Good afternoon! Some dumb questions incoming as I'm early in my research.
OVERALL GOAL: Maintain grid tie but also install a battery backup to power some of my house during power outages. Seems like swapping to a hybrid inverter is the solution to this. This doesn't have to be seamless...I can manually switch to battery power if it makes it easier/cheaper.
CURRENT SETUP:
Solar edge HD wave inverter 10kw, grid tied with net metering active
28 Mission 295w panels (see picture) w/ solar edge optimizers. A string of 16 on the roof, and a string of 12 on ground mount. So two separate strings coming into the inverter, not balanced in wattage
These splice into my one of my two 200A breaker boxes located next to the main power run/meter.
PLAN:
1) Buying an EG4 18KPV hybrid inverter
2) Swapping the EG4 in for the SolarEdge
3) Eventually adding somewhere around 20kWH of batteries...probably the EG4 lithium setup.
QUESTIONS/CONFUSED PARTS:
1) As far as simply swapping inverters and acting as only grid tie, is there anything I would need to "change" compared to the SolarEdge wiring/tapping into the 200A panel? I feel like the answer here is it will just work?
2) Once it's time to add batteries I get in over my head with wiring.
I think this is the wiring diagram I will need?
This all seems very much "professional electrician" level, unless I'm way off base.
Is there an easier/more DIY way to do this battery part while maintaining net metering/grid tie? I have already moved all of my "crucial loads" to the basement 200A load breaker panel, which is fed from the 200A breaker the previously solar install tapped into to grid tie.
Thanks for your time. The more time I spent typing this the less optimistic I became about this being a DIY project for me...but maybe I've just gone down the wrong approach completely.
