So the issue ended up being , as far as we can tell at this point , a loose neutral connection at the first load distribution panel feeding all loads after the inverter.

Ultimately it was replaced with a Lochinvar and that solved the issue. Magnum asked for the Buderus for testing, but that never happened, as once the problem was resolved by the heating contractor it was forgotten. This issue was addressed on this list around 2/10/09, if you'd care to peruse the archives. To make it easier, I'll forward you a few of the emails, including a compendium of Wrenches responses, off list. I'll also note that I have used a MS4024AE in my own home since 2010. It's been flawlessly reliable. However, every time the fridge comes on the lights flicker, especially one chandelier with 6 40W incandescent bulbs on a rotary dimmer. And one client with a MS4448PAE I installed in 2011 complained that while the inverter worked well, anything in his home with a clock built in ran slow and had to be reset at least monthly.

The most troublesome issue is the new Rheem wall-hung LP instant water heater/boiler is throwing an Error Code 12 which is supposedly a “Flame Failure”. It’s a brand new installation with new tanks and lines and the gas guys have doubled checked everything. We are now wondering if it might be related to the power supply. The other indications that it could be related are flickering lights, a 12V battery charger (AC plug in type) that won’t work off inverter power (but will when plugged into the genny, and I’m seeing a little bit of wondering in the Hz on my simple Exeltech volt meter. Magnum recommended a run capacitor on the boiler circuit. I installed that on Friday and still had the error code come up 4 times over the weekend. Any thoughts?

Just a nick into the metal can corrode the cable all the way through over time. We use conduit for almost everything anymore. The savings with URD doesn't pan out, when you have to abandon the line after 10 years.

One client lately has been experiencing voltage drop and failure of PCBs in two of his household appliances. I know it’s common to have some dimming of the lights when a well pump or other large load kicks on, but has anyone ran across a solution to alleviate the problem or boost up the voltage / condition it, in any way ? I’m not sure if this just happens with low battery voltage, or always The inverter is located ~ 300 ft from the main electrical panel with #2/2/2/4 URD feeders to an outdoor disco, then 8 AWG copper to the mains panel. 4448 PAE with one string of 6CS21P Batteries.
