1: Where does Aladdin get its solar voltage input? From the charge controller?The Aladdin DC Interface (DCI) is responsible for reporting the solar volts and amps. The solar controller has a fused output for voltage reporting and a current sensor on the ground wire, both are connected to the DCI. There is a section in the Aladdin troubleshooting guide that discusses calibrating the DCI.
3: Is the Magnum ARC remote a drop in replacement that adds lithium settings? I know I need to figure out if it is compatible with the model - will go check this weekend?I have not converted to Lithium batteries, but I came across the following information after our Magnum MS2812 failed and I was researching my options. I ended up having our invertor repaired which brought it up to the latest version, 6.0.
The inverter in your coach is probably an MS2812. Some of the All-Electric Patriots and Marquis came from the factory with two inverters and 8D AGMs.
Originally, only the ME-MR and ME-RC remotes were to include the new Lithium profile, that may have changed. It’s my understanding that to take full advantage of the Lithium settings you may need to upgrade your inverter. You can upgrade your existing inverter to the latest version (6.0) by installing a new control board. It can be DIY upgrade.
The control boards are kind of scarce right now, but I found some at Zonna Energy, ~ $330.00 with shipping, delivery time was about a week. The part number for the MS2812 controller is TCB-MS2812. If your invertor is not an MS2812, Zonna does list control boards for other models.
A call to Magnum would be beneficial, they are very helpful once you get through. Zonna Energy was also helpful.
Here are couple links for the Magnum Lithium setup.
