So this is what I have.
10.8kw system using enphase m215 micro inverters
Trying to figure out if my grid ever goes out my whole solar system goes off line and all that solar is useless.
So I bought a mpp lv6048 inverter and a eg4 5.12 kw battery bank.
I hooked up 9 solar panels separate from my house to feed the mpp inverter and charge the battery bank completely off grid. I basically hooked up a 30 Amp 4 plug extension cord to power an window unit and fridge, and so far works perfectly.
So here's my question
Is it possible to safely shut the main breaker off feeding power from the utility power grid. And back feed my sub panel with the mpp lv6048 and put 120 volts on each leg to send power and fool my main solar system to think 240 is now present and for the whole system to come online.
I seen some post comments saying I'd have to use up all the available power my solar system would use to keep from frying things in my house. I'm a little confused as to why it would burn my devices up considering the grid is constantly having 240v sent to my house and if I'm not using alot or if I do power is always present no matter what. So how or why would it be different if I shut off power from backfeeding the grid and I just have a constant power source waiting to be used?
Also I have a metering device and even tho I have a 10.8 kw sticker plate output at best with optimal sunlight I max generate only 8.9kw max.
And I don't plan to try and run my whole house just to run the essentials like fridge and lights and window units. I know the main central ac unit will be too much for just 1 battery bank.
If anyone with knowledge can direct me how to do this safely or if they had success in fooling it please let me know thanks
