Re: [RE-wrenches] EG4 battery OK with Magnum electronics?

[Jay via RE-wrenches]

Ok that makes sense.  I mean it’s a giant hole in the programming, but ok  On Aug 26, 2025, at 3:51 PM, Kent via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:  Fuzzy memory here. It had to do with a setting that should have been adjustable but wasn't. I think the voltage start won't trip until the voltage goes below the re-bulk voltage (not adjustable - it was designed for lead acid). Obviously it depends on the firmware version, the lithium compatible firmware doesn't have that problem. A Morningstar relay driver makes for a suitable AGS as an alternative.

A buddy had a nightmare situation trying to get that to work, even just with voltage it never worked right.  Doesn’t make any sense.  But then I had nothing but problems with magnum and gave up on them.  I know others here who love them.  Jay On Aug 26, 2025, at 2:00 PM, Kent via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:  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.

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!"
