Xantrex SW3012 Fan question
After suffering with an old Xantrex RS2000 for 11 years, I found a used SW3012 and just installed it. Upon power up the fans ramp up to full speed, then shut off. 3-Stage charging began at about 120 amps, but rapidly decreased as my batteries were not discharged very far. The fans never came on. Is this normal for the SW inverter/chargers?
I'm used to the RS2000 fans running constantly.
I haven't tried the inverter yet, so maybe the fans run only in inverter mode. Anyway, if some SW2012/3012 users can let me know their experiences with when, if ever, the fans run, I'd appreciate it. I did open the case and cleaned checked everything before installing. The fans spin easily, and remember, they do spin up momentarily upon power-up or reset of the inverter.
