[RE-wrenches] Dual Channel Inverters

[Chris Mason]

What you are asking for is the Sunny Tripower 10/12/15/17 3 phase 2 mppt
input inverters, which we are using in the 415V locations but are not
available in the US. I don't understand why, they are fantastic units. The
units have up to 6 string inputs, string monitoring, built in electronic
safety switches, really neat equipment. We need to pressure SMA to make
them available States-side.
