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.
