I've been at SPI for the past few days and thought I'd list some notable discoveries here.
-Midnite Solar is working on a 600V in, 130 amp out charge controller called the Barcelona. Said it would be released within six months.
-Skybox from Outback (5kW grid tie inverter that can use batteries or no batteries) is now shipping.
-Several rapid shutdown solutions including one (QF Energy) that's just an in-line MC4 connector
-New load center from Q factory that takes a 200 amp service and allows 200 amps of load and 200 amps of backfeed
-A "crypto mining" system by usolar that uses solar + batteries to power a series of multicore processors to mine for bitcoins and the like. It disables/slows down processors when solar input is insufficient.
-It's becoming clear that interfacing li-ion batteries to the charge controller is becoming a big stinking problem. Several vendors had lines of "adapter boxes" that would translate xanbus to modbus (for example) so you could use a Discovery li-ion battery with an Outback inverter. But still, most batteries won't work with most inverters, because there are so many of both.
-vutiliti has these little current sense transformers that are powered by induction and use wireless communications - so you just clip them around an AC conductor and you are done. No other wiring.
-ampt has a micro"inverter" solution that goes direct to battery. Modules on the panels convert panel voltage to 400 volts DC which is directly fed to a battery.
-Eaton has a line of remotely operated and monitored breakers for load control/monitoring. But they take up two breaker spaces. Who has extra breaker spaces?
