The SB2512iX-HV(-Li) features our patented MPPT technology, a second auxiliary battery output, and IPN connector for remote display, which is ideal for RVs and Marine. The SB2512iX-HV(-Li), can manage a 25A DC Load Output and with an IPN ProRemote, BT Connect, or UCM, the DC Load Output is fully programmed. The SB2512iX-HV, is programmed for Lead Acid batteries while the SB2512iX-HV-Li is programmed for charging 4S LiFePO4 batteries. Both versions can be programmed with a remote display, UCM, or BT Connect for a custom charge profile for any type of battery.

I bought this to replace the original I got used in 2015. It started overcharging my battery. So bought a replacement, exactly like the original made in 2012.

All I know is this unit worked when my old one did not. This was a one for one replacement. I’ve been using the Blue Sky Charge Controller for many years now without a problem until my Inverter/Charging unit in the motorhome burned up and cost me 4 new batteries.

I've used one of these with the remote display on my boat's solar system for a couple of years. It is a solid and efficient MPPT charger that consistently gives me about 20% extra charging current than I would get with a straight charger. It starts being a positive contributor to the charge output when the solar is delivering more than about 1.5A - not hard to do. Below that, the extra overhead of the MPPT switching actually decreases your output current slightly.My comments will be about the system with the remote unit - the remote makes programming this super easy and gives great information. Multiple 2512 controllers can be put in parallel to allow higher-power systems, and I am adding a second unit in now as I increase my solar capability.The unit has a tremendous amount of programming capability to allow it to work with virtually any battery type. It has a secondary output that can be used either as a switched output such as a light control, or a low-power "top-off" for an additional battery. In my system, I have a 500A-H house battery bank and a separate starter battery. The secondary output keeps my starting battery charger nicely.The entire unit is a metal heat sink for the controller. It's easy to mount, but needs to be in a dry area since there is no waterproofing. It has good efficiency on the power conversion, so the case stays at very reasonable temperatures.I've specifically investigated whether this unit is creating much noise on my SSB radio, and have been happy to find that it does not. I installed a switch on the solar side to kill off any large switching transients just in case, but find that I don't use it.I'd give it 5-stars if it was better protected for marine use.

after purchase I should have looked for larger unit, 20-25 amps isn't much.

Great charger/Controller. It Fits in a standard 11B electrical box, a little tight but the compact form makes it easy to Install anywhere. I've only got hundred watts or about 5 A going through it and it handles it just fine.
