HI to all I notice my lights in the house would go dim for about 10 /15 seconds and then come back bright. When it happened again i got out my volt meter and checked the voltage which read 98/99 volts ac, then came back up to 150 ac after a few seconds. I then went to the main panel and measured across the two "hot" terminals and the voltage was 259 volts
This is a MAGNUM MS-PAE PURE SINE WAVE INVERTER/CHARGER just under 2 years old . Is it on the way out ? I tried a reset per the manual same thing happened.
Look for a loose connection in the DC & AC sides in the power shed. I'd had flickering lights for about a month, and was suspicious of the 80' cable over the creek, when one day I was in the power shed watering batteries, and I heard zzzttt zzzztttt ztzt. Tracked it down to the main panel meter socket, which had no meter, but some jumpers installed by the "electrician" they had been arcing (the bars were steel) and heated the copper grippers to the point they were loosing tension and were not connect well, which lead to arcing and heating........
R All connections are snug &tight, batt voltage good. Here is what i did, turn off the input DC breaker waited 10 min,turn back on held the power switch untill light flashed (searched mode) turned breaker off. Repeated the process after 20/25 min held pwr sw for 15 sec rlse until led blinked,waited 1 min hit pwr sw inverter came on ,turned on main panel breaker and the AC voltage was 125 and steady but to me still high between (l1 to grd 125v) between l1 & l2 259 volts ac

Not sure why the lights would dim except for either a bad connection or a bad inverter... bad inverter feedback actually.
Also, the drifting voltage kind of sounds like your meter was looking between two non-synchronized AC waveforms
like maybe the grid on one lead and the inverter output on the other lead.
Do you have more than one PAE inverter, stacked ? What kind of meter are you using ?
Hopefully a decent one at least.

I will point out that the Magnum does have some odd regulation. I gave up and took mine out as it drove me nuts living with it.

<I will point out that the Magnum does have some odd regulation. I gave up and took mine out as it drove me nuts living with it.> Halfcrazy i hope i don't have to "give up" on mine so soon
boB only one inverter and th emeters used to check were (craftman digital multimeter & southwire clamp meter both show the same
Today sunday as post this the inverter seems stable 122 vac on both legs i did a reset three times and that seems to have cleared it (hopefully)
ps of all the inverters i've hade before MAGNUM proved to be the best
