#1 -  Renewable Energy > Technical Discussion: Other > how to set up a battery based PV system with GRID BACKUP
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

Just on the outside chance you still have the inverter, I'm interested. Is this still for sale?

IS this still available? I have a 5 yr old sunnyboy SWR 2500 that I need to sell/trade for a GTFX2524.  Thanks, Dennis.
