Yes, you read that right. I live in Hawaii, where the utility rates are .$.40-$.50/kWh. I want to design a system that relies on batteries, but backs up with the grid (instead of a generator) I'm hoping that a good outback GTFX can be programmed to do this(and that it will be easy?)...but it's not a typical application, and to boot, I have no experience.
There are a number of reasons I want to do this; (1) I'm not confident in the long term viability of the grid, and (2) we can no longer net meter here, so if I grid-tie, I have to buy at $.40-$.50 and sell at $.20-$.30. (3) I run a B&B out of my home so I can't go completely off-grid yet (people bring hair dryers) and a generator would be too loud.
I just picked up a used PV system - (20) 24v BP panels, but it came with a sunny boy grid tie (swr2500U, wanna buy it?)
One more thing...I may add a wind turbine in a year or two.
Am I crazy? Beyond help? What should I read first? Thanks for any and all help
Aloha from Kauai
