Hi Dana, If the Trace model is SW, it will not be approved for selling if it was manufactured prior to 2002 (non-GTI model). If the batteries need to be replaced, the added expense may be considerable depending on the size of the bank. I guess it depends if the customer really wants backup. You

[RE-wrenches] Tigo and SMA AFCI - Was: AC coupled, grid-tied Sunny Island - contactor bypass

2013-06-05 Thread SunHarvest
Just an FYI for anyone wanting to use Tigo optimizers with SMA inverters incorporating AFCI - According to SMA the Tigo optimizers will not operate with the SMA inverters. They didn't go into detail. They just said the AFCI feature of the Sunny Boy is not compatible with Tigo. After further

SolarEdge makes an optimizer / inverter system. We just installed one. Our clients are happy. So are we. Don't know if you can AC couple the inverter. Their website says they are about to release a version of the optimizer that will work with other manufacturer's inverters. Dick Ratico
