Magnum makes very reliable, quality inverters and has the customer service
to back it up. It's now our #1 seller for small systems and has replaced all

If you choose Magnum, be sure to look at the ME-BMK for battery monitoring

Re: [RE-wrenches] AGM battery charging, more details"Until now"?.
For proper VRLA battery charging, once it is full, you MUST reduce the voltage.
It does not matter that you are opportunity charging. What if your turbine is

Hi Hugh,
An AGM battery is considered full when the current drops below a specified
amount. Lifeline, for instance, is considered full when current is less than
0.5 amps per 100AH. The Blue Sky Energy IPN Pro Remote

My suggestion: temp comp, ground vault, HUP or equivalent cycle life.

Roy,
Your post is most puzzling. As temperatures rise above 25C, battery capacity
rises and cycle life is shortened. The opposite is true as temperatures drop
below 25C. What do you mean by he was loosing "capacity" during summer months?
My question is whether anyone has run air conditioning o

I wonder about the suggestion of using a Class T fuse. Here's why: Class T's
are extremely fast on a dead short but is that what you have during a thermal

circuit current for brief periods of time. Fo

AGM batteries account for over 50% of our battery sales. One of the
beautiful aspects of AGM's is that you can hammer them very hard during the
initial bulk charge stage. Their low impedance makes this easy to do. More
than likely you can't make enough current to come close to the maximum

Wrenches,
Some of our business involves repairing poor PV solar installations on
recreational vehicles. So often we wind up installing a roof junction box and
running a second PV to controller wire and then replacing the controller to
battery wire size. For instance, we may find a 10 gauge wire
I believe the issue we had has to do with using the Sanyo high voltage PV
module. As Kent points out, we were operating the controller at the design
limit. I don't believe it is suited to do that as we have other Morningstar
MPPT controllers working fine for several years now with lower voltage
I have had failures with the Sunsaver MPPT. I have used them with a single
Sanyo module in small battery systems. Perhaps they just can't handle the 50.9

There is an exclusion of warranty if any Sharp PV module is "installed in a

It looks like you said the battery was replaced with Rolls. If so, good choice.
Without extensive regular testing, keeping a log book, and possessing the
knowledge to do it right, you will not really know if you are fully charging
the battery to 100% SOC. From the information in your p
Hi Drake (et alia)
An quality inverter/charger would work for half of our situations. The other
half is that we do capacity recovery of AGM and flooded batteries. For that I
need unregulated or controllable voltage and manual current limiting.

I was hesitant to reply because I surely will look foolish, but perhaps it may
help someone in the future. I did something very stupid back in 2001 that
caused an explosion.
The battery bank (12 volt, 660AH) was located in a metal cargo container next
to the wall and set in a plastic container
Interesting. A customer from Baja, on the Sea of Cortez has a similar problem
after 2 years trouble free. No ESD potential there. Rebooting the remote did
not help. Did Outback pant a time bomb!!
