Jay,
I would think these very important features would be listed in their data sheet
but they are not. Their website does not offer any installation or operation
manuals for download. If you have any evidence to this I would like to review
it.
In my experience, battery charging is a highly mi
Hello Wrenches,
I had an unexpected glitch in AC coupling a Magnum 4024 PAE
inverter. The system utilizes AGM batteries, which (according to
Concorde tech support) have a very strict upper voltage limit.
The relay used to stop the current input from the direct grid tie

Drake,
Charging an AGM battery does not have to occur at the maximum charge voltage
allowable; you can charge at a lower voltage for longer periods of time and
still achieve 100% SoC. Since you have grid power to work with, slow down the
charge cycle.
Assuming you have a late model ME-RC and v
Drake,
Magnum's approach does not use disconnecting the AC output from
the GT inverter as a fail-safe method of preventing battery
overcharge. Rather, the Magnum documents I have use a DC diversion
controller and diversion load for this purpose. Their method
Meant to say, "You should tweak #3 & #4 above..."

OK, a bit more:
The line diagram I was referencing was dated 5/1/2010. A later
diagram from a Powerpoint given at last year's NABCEP CE
conference shows a "MagNet" AC diversion controller. It allows AC
diversion loads and three-stage charging. No mention of temp c
Hi Allan,
In answer to your question: Yes, we're developing an AC side 4kW
diversion mode controller which allows temperature compensated three
stage charging for AC coupled inverter applications. It is currently in
beta site testing.

ANDyou are still working on that stand-alone, programable, temperature
compensated battery chargerright???
Thank you,
