Hello All!
I have been following Will for some time but never felt that I have a real need for battery backup. Until last year my electricity was 8.5 cent/kWh while I was locked in a very long contract. When I renewed with another company it went up to 10 cents but looking at the current renewal rates and the things to come (rolling outages) I have a complete renewed interest in solar and battery backup. My average usage over the last years per month is 3000 kWh.
Here is my
(A) MINIMUM setup / need:

My average usage over the last years per month is 3000 kWh.
Here is my
(A) MINIMUM setup / need:
- keep grid but have automatic switch over to battery backup on certain circuits (I have 4 critical loads 2 x refrigerators and 1 x freezer and 1 x security & internet) ~ 400 W
--> I was thinking the EG4 LifePower4 48V 100Ah and the EG4 3000W Offgrid Inverter as seen in one of Will's videos
- What I am missing in this picture is a recommendation to an automatic switch that disconnects the grid so I do not feed back. The wife factor is really important here and I can not rely on someone physically switching this on power outages.
- same as above but be able to also use PV generated power to reduce the bill in the future
--> the Ecoflow Delta Pro seems to be headed this route, especially with the smart grid pull out panel.
- Downside - very high cost and potentially some uncertainties on priority (automatic) charging Delta Pro from PV and/or grid
- same as (A) or (B) and Gas generator automatic tie in in case batteries drain too much
--> I had seen a video (can find it anymore) where someone had the inverter automatically start the gas generator in need to refill the battery banks. Does this work with (A) or (B)
