I use OpticsRE on my off grid system. It seems stable in its current
revision. There are a few things that bug me about the GUI, such as not
being able to make drop-down preferences retain settings on log-in for

HI Todd,
Thats not my understanding.
VRLA batteris come just like FLA, cycling and non cycling.
I can’t speak to the non cycling as I don’t use them.
But cycling VRLA are lead/antimony, not lead calcium.

HI Ray,
yep agreed, the brain power is going towards Lithium. Thats what I would do.
Schneider also has a high temp shut down.
Not sure about OB, or magnum.

I’m using the Optics RE at my house. Its pretty easy to hook up.
The newest rev works well with Power line carrier units.
And its free

I have several existing off-grid sites that now require remote monitoring.
All of the systems are Outback FX series inverters with hubs, original
Mates, and relatively easy WAN access. I keep coming back to Outback's

Hi Larry and Jay;
I totally agree, that taking into account charge and discharge rates,
DOD, and temperature, we should be able to more accurately model a
battery's lifespan. We already have temp sensors at the battery, so it
seems just a matter of software to do this. Also battery's nonlin
Do you have any specifics as to why the Sanyos's were failing ?
Thanks, Ken

Hi Larry,
I've talked to Ralph about adding temp comp and puekerts.
But he doesn't know think that it matters, I don't agree with him though.

We just got a dozen from CivicSolar last month for a Sanyo replacement on an
existing Wattsun AZ225. Nice boost in power, seeing 270 watts output from each
240 watt module on the APsystems YC500A microinverters. It was a cold day! Took
off Sanyo 195 BA3’s that were failing big time.

as i understand it agm batteries are lead calcium. my personal experience has
shown me that lead calcium is THE battery for ups systems.
to reiterate previous emails about this:
i have two grid tied systems here at home, both with battery backup (outback
gvfx series) inverters. one has 1986 vi
With relays you can set the A/C up as a
dump load that will activate when the grid goes down.

No hydrometer, no log book, many cells at different SG and probably no battery

I reduced the system to one string when I was on site, and it is maintaining,

Jay,
And, and, and, indeed. There are SO many factors affecting battery life. With
some battery capacity monitors (like Blue Sky Energy IPN-Pro), you can see the
total kWh removed from a battery bank since it was installed. But that data
does not consider the non-linearity of the DoD/Cycle life

We’ve also used the ECO-65 which works great but the problem with your roof
