Hi William,
If you recall a couple years ago we had some discussion here about a problem
with a specific make appliance being powered by a Magnum inverter. The problem,
it was discovered, was the appliance input PF was creating current demands that
the transformer based inverter could not keep
A Sunny Island that switches to and from grid power probably does not
transfer smoothly enough to protect sensitive equipment, but if it is
online all the time, using solar to charge the batteries, I would not
bother with a UPS.

If the SI system has enough reserve, run it totally off-grid with the grid
as backup. Then they will never see any transitions.

Document then DUMP IT! With the power logger you would also be able to capture

Hi William,
Power quality, in your case, refers to how close to 60 Hz (frequency
component), 120/240 VAC RMS (amplitude component) your voltage waveform
is. Every waveform is the superposition of different frequencies,
amplitudes etc. Power quality requirements for a devices input or output
are
I have in the past have used the Fluke power logger 1735 , It will monitor 1/3
phases voltages spikes/dips in V, A, Hz , +++ AND one is able to print out a
time line of all the "occurrences" that may trip the UPS. I rent this from some
folks in Texas quite reasonable ~ $230/month or weekly too.
Friends:
I am still having a pi$$ing match with the company that installed the
expensive home entertainment system for a client over the issue of power
quality. The UPS beeps frequently and the AV system crashes now and then.
The lead installer has copped an attitude and is blaming the Sunny I
