I am running total solar - which means I have long term solar thermal storage as well as solar PV. Any excess PV can be stored as heat in my solar thermal system. I just need to switch on electric water heating as the battery bank gets full. I want 100% output - no throttling - no shutdown.
I'm currently adding 2KW/M250's to my existing 2.5kw system which has m215'S. The utility is planning on reducing the credit for grid tie from 1-1 Kwh to 1-.2Kwh over 4 years. I won't lose 80% of the value of my production with this utility. I have discussed Enphase AC coupling with several...
Also, I'm in Idaho which has the best electric rates in the country. Hate to be in CA or HI where the rates are ridiculous. Payback would be much shorter there.
I expect to be doing AC coupling M215/M250's with inverter/LiFePo4 batteries. The question is not whether you can do this, but why? I currently am grid tied. The problem is the utility wants to change their net metering process so that instead of a 1-1 production/consumption credit, there want...
