Re: [RE-wrenches] Magnum 4448 PAE whimpy charge rate.
Hi John, I have been vexed about the settings on the 4448 PAE in off grid scenarios too, but am trying to figure out how to make these work as intended? That being said there's a couple of settings that might be messing with this that you can check out. I am also open to any suggestions here, thanks. Recently I was programming a pair of these using the RTR, check in 02 Control Charger that you're using Multi-Stage. This is also in the Setup 03F Final Charge Stage menu. In Setup 03A AC Input Amps, 60 to 70 Amps max with 1 inverter and 1/2 that with 2. You have probably already set 03E Max Charge Rate up to 100% I reckon. If not give it a shot and see if it will approach the 60 Amps DC per inverter rating. Anyway these RTR menus are from 2014 +/- so I don't know if you have the same menus. Hope this helps.

Re: [RE-wrenches] Magnum 4448 PAE whimpy charge rate.
Hi John, Are these made in Mexico units? We have had a few issues with quality control since the relocation, not specific issue you have, but charger-related. There are two settings – Under the Shore menu make sure Amps are set properly, and then there is the battery charge rate in the setup menu. That inverter should give a 63A charge @ 48VDC, and generally doesn’t really care about power quality even with very cheap generators the charge rate is good.

Re: [RE-wrenches] Magnum 4448 PAE whimpy charge rate.
John I would try the Victron Cerbo GX for remote control of stuff. It has plethora of ports (I/O and temperature) and they can connect to lots of different devices, especially other Victron items like inverters and charge controllers and smart shunts (that one I’d also add to the Cerbo right away for SOC). 1. Cerbo GX 2. SmartShunt 500 amp Battery Monitor (Bluetooth) 3. Temperature sensor BMV-702/712 for the shunt. 4. VE.direct cable of correct length to go from Cerbo to SmartShunt Cerbo GX connects to the internet via wired or wireless internet ports provided. They have a cellular modem add on as well. Victron offers a VRM virtual remote monitoring via the web.
