So, my super duper modular rectifier modular inverter office UPS was not working. It would run for a little while and then have an inverter failure.Swapping cards, narrowing it down to the control card... but I kept noticing low voltage.So, out of an abundance of caution I actually measured the batts. 43 volts. Hmmm. Rectifier light is on. Oh yeah... there are some circuit breakers behind a panel that you open on the front.Turns out, that you need to actually turn the charger ON to make the system work.
