Sunnyboy 1800U (120V?)

This is the first time i've installed a 120V Sunnyboy. The array is 1.6kW. Seems a little much to be putting on one leg of a panel. Anyone have experience? Also, the run is close to 100', voltage drop will be higher than with 240.

    oK actually, maybe we won't be specifying the sunnyboy 1800. My distributors have discontinued them. There aren't really ANY string inverters available under 2-3kW are there??

    Xantrex GT2.5 is the smallest I know of , price wise is is less than the SMA 1800 unit

    You may want to check out the Kaco 1501x Blue Planet string inverter. Rated at 1501W. There is a distributor I have worked with in the past called Krannich Solar in NJ that carries the Kaco brand. Don't know if NAWS carries them.
