Nick,
I guess I don't see this as a weakness but rather operating as designed.
If the design intent was to allow the grid tied solar array to provide a
limited power source during a grid outage, during daylight hours, with no
batteries required, it seems this hits the mark.
I know these units
Hi Larry,
I will bump up the absorb voltage to 29.6 V. How
long do you think the bank should stay in absorb
at that rate? The bank now seems healthy, with
the bad battery replaced. It does accept charge,
without going high prematurely. The max charge
rate from the array is around C/10.
Our local inspector is allowing sticker-type labels, so we have begun
printing our own with a laser printer. We found weatherproof sheets
available in a variety of size configurations:

For interior applications I am using the Avery 5522 Weatherproof labels
successfully on the the SMA inverters as well as other equipment. For
external applications I use engraved plastic laminate labels from Action

Keep the absorb rate recommended for the CC. The trimetric strays over time and
will become accurate again when you overcharge (equalize)
The math:
Amp hours of battery @ 20 hour rate divided by max charge available in amps,
from whatever you using to charge (solar or inverter/charger)
Hi Tom
Where did you get the .42 from?

Drake,
When you said, The batteries usually reach absorb voltage shortly after the
sun hits the array, I wondered if you had more of a problem with that system.
Glad to hear it's not that way.
Absorb time is an issue I have with the design of most charge controllers: They
do not measure

I have not installed any SBs with the "SPS" feature.
My understanding is that manual activation and deactivation of the
SPS grid-loss outlet is required.
Not a big deal, but the homeowner has to remember to deactivate

If we have another long outage here in CT and we seem to have one every year
now, I don't want to have to explain to my customers why I didn't use this
inverter.

Larry and Tom,
Thanks for the information. I will boost the
voltage and the charge hours for the array. The inverter is good as is.
The batteries charge quickly since they are not
generally cycled deeply. The cabin is only used
for three or four days a week, giving the
batteries plenty of
Hello, Motorheads~ and with a cc to SolarConverters since I'm casting in
all directions for answers.
Another solar guy left our town abandoned a pond aeration system. The
owners asked me to be their new guy, but we're struggling with motor
problems way too soon.
