A ~$2k pricepoint does make more cost sense, but who knows how long it's going to last. At that price point a Phocos might be a better bet.
So far I'm into my Radian 8048 system for about $4950: Radian $3720, Mate3s $430 and three Midnite Classic 250 CPs for $825.
Right now I'm getting nickle-and-dimed to death on the balance of system: cables, breakers, breaker panels, etc, etc, etc.
The radian/mate3s natively speaks modbus and is fully sunspec alliance compatible. The inverter is 92-94% efficient above 800 watts, about 80% below it.
I think I'm going to stack another GS4048A-1 on it for a 12k system, if you've got a good deal I'd like to hear about it.
