Hi Ron,
As many on this list have suggested, it sounds like a sulfated battery
condition. In your last message you revealed something to me that absolutely
confirms this but perhaps you didn't recognize it.
Battery voltage readings are deceiving because they do not indicate capacity.
25.7 vol
I've seen behavior like that from Series 5000 Rolls that were only a
year old, but chronically under charged. (20 amp load and the inverter
would reach low shut off in minutes, 30 amp charge and it hit high
voltage and quit charging) Any other battery, and I would assume its
capacity was gone.
Other examples of NEMA 3R enclosures are virtually all meter bases,
outdoor service boxes, pole mounted disconnects, air conditioner and
other roof mounted disconnects as well as wiring enclosures for
changing wiring methods from underground conduits to building
interiors, which generally make

I received the letter below from Photon magazine. I am posting it hear because
it seems like a great way to get an answer:
Hi David,
Over the past year, Photon magazine's German publication has been reporting on

I have been following this topic over the past couple of weeks. What Dave
Katz said matches up with what I have seen over the years. Although it can
be difficult to diagnose battery issues from long distance there has been a
fair amount of information that points to sulfation. I think Mr. Katz is

I don't think it was the water. It was probably the 10 hours they ran the
generator that brought them up a bit. If the water is low, the electrolyte is
more concentrated and will make the s.g seem higher. Adding water to the
proper level will make the reading more accurate.
I still think

The nice thing about the Exeltech (and what made me decide to use
them) is that they are not "large". They are simply an array of 1 kw
inverters, allowing for multiple redundancy. Essentially, a 30 kw
three phase inverter is 31 small inverters, which, with the removal of
two nuts, can be s
