Mick,
I've connected other LFP batteries to the Magnasine. It is possible to
make the charger settings all work but it is difficult to get the AGS
settings right for a start voltage. There is a "lithium compatible"
firmware version for the remote, but good luck at find one of those for now.
The elephant in the closet with the Magnasine is that if the system goes
through a power-on cycle with the remote detached, then the inverter
operates with its default settings.

Hi, Mechanix~ A longtime client has a Magnasine 4024 inverter/charger,
PT-100 charge controller, BMK battery monitoring kit & the ARC
Advanced Remote with 4.0 firmware.
He'd like to upgrade from L-16 floodies to five of the EG4 LL24V 200
AH batteries in a cabinet.
I've reviewed the EG4 info for care & feeding, alongside various menus
in the Advanced Remote manual, and it looks like the Magnum setting
ranges are compatible. Before shipping out the money,
I'd like to know any feedback from the Wrenches about how things are
working when these product families are combined.
At times I've noticed strange behavior with the Magnasine inverters
during charge cycles. As I recall, the units jump from Bulk to Float
soon after generator driven charging gets under way. For clients with
old or compromised lead acid floodies, I've occasionally set Float and
Bulk to the same target voltage. These are off grid setups where the
generator noise keeps the client aware that charge is underway. Most
of these clients don't have the generator automated, which is also
true for my 2025 EG4 customer.
I won't try that "Float @ Bulk voltage" trick with lithium, of course.
Any & all war stories would be welcomed. As always, "The Wrench List
is the Bomb!"
