Best controller I've been able to find. Been using mine for 2 years charging a 12v bank from a 48v array. Biggest problem I have is the ReBulk setting (voltage that must be reached before a bulk charge is reinitiated) can only be set in 1 volt increments - I would prefer 0.1v increments. The reasoning here is the 13v setting obviously forces a bulk charge every morning. The next available step is 12v (which translates to approximately a 40% charge) is too low. Battery freezing becomes an issue (about 5F at 40%) and I don't like discharging that deep. 70% is my preferred depth so a 12.4v setpoint would be reasonable but it can't be done. If your bank voltage is higher, this becomes less of an issue. The 150v limit is a minor problem, 250 would be nice, but I can live with it.
