Re: digital Clock wont keep time
Hi mr. mike,
Most inverters use a quartz crystal to determine the output frequency. Some appear to be trimmed or set for exact frequency within fairly close tolerances, but still there will be variations when taking into account temperature and voltage changes etc.
At my off-grid site use battery-powered clocks, altho I do miss an illunimated digital clock. But expecting an inverter to output very precise frequency over a long time is expecting too much, especially when using a fairly inexpensive inverter (nothing against your inverter).
Even when on-grid, several of my digital colock do not keep perfect time -- things happen to the AC waveform which cause the clock to gain or lose time. If you really want to see clock errors, use Search mode !
you might call Morningstar, and try to find their spec of freuency tolerance, and if they feel that this is out of spec.
BTW, i have never set the clock on the propane stove, or the Microwave, so I dunno about the accuracy of my inverters.
Good luck, vic
