Yes, the point is 'no grid no power' - and I'm talking about how to use the PV with the grid down or non-existent - I'm not talking about letting the grid-tied system go to sleep so that I 'get' to keep adding another five gallons of gas to the generator. I think Queen missed the context before you piled on , though I may be wrong...thew said:AndyH said:No I don't, because I'm not talking about generators. One does not automatically require the other.QueenBee said:If that is what you want to know then you need to include all the people who have fossil fuel generators as backup. Much cheaper to buy a ICE generator and convert it to natural gas. Still has maintenance costs though.
I thought the Point was No Grid no Power..
Can anyone guide me to charge controller info that says they intentionally drop away from MPPT and move into an inefficient place on the E/I curve? I've read through some MPPT code but don't have much experience with this - but I've not seen or read anything that suggests this is true. The only instance I know about where panels are allowed to intentionally warm is when a charge controller has a 'snow melt' function. Thanks!
