Blue Sky Energy Solar Boost 2512i-HV 12 Volt 25 Amp Multi Power Point Tracking 3 Stage Pulse Width Modulation Solar Electric Charge Controller


The 2512i-HV is the new replacement for the 2512 controller. This is Blue Sky's lowest cost 25 amp output 3 stage MPPT solar charge controller. It is an excellent choice for RV solar electric systems under 340 watts with 12 volt 36 cell modules producing 20 amps or less or 270 watt of 60 cell modules. The 2512i_HV does not include the battery temperature sensor input, IPN network input, battery equalization feature or the auxiliary output circuit.

From the Manufacturer

The 2512i-HV is the improved version of the original 2512i solar charge controler. The 2512's Patented Maximum Power Point Tracking (MPPT) technology allows the Blue Sky Solar Boost 2512i to increase charge current up to 30% or more compared to conventional charge controllers.

The new HV versions retain their original 25 amp 340 watt rating when used with conventional 12 volt nominal 36 cell solar modules, but are also able to operate up to 270 watts hof higher voltage 60 solar panels

The Solar Boost 2512i-HV provides a sophisticated fully automatic 3-stage charge controll system that improves battery performance and life while minimizing battery maintenance. The 2512i is fully protected against voltage transients, over temperature, over current and reverse polarity. The IPN Network display connector allows the use of optional IPN emote display or a UCM (Universal Communication Module).

The following features are not included in the 2512i-HV but are included in the 2512iX-HV: Battery temperature sensor input, Battery equalization, IPN network interface and Auxiliary output.

Notes for the Installation Team
We have not installed the Blue Sky 2512i-HV because we only offer our installation customers the 2512iX-HV controller. We also don't install the higher voltage 60 cell modules because we can generate more DC amps per square foot of solar module with 36 cell panels.

The Blue Sky 2512i-HV is a fantasic MPPT 3 stage pulse width modulation solar controller for small systems of 340 watt or less. The controller has a maximum closed circuit solar amp input of 20 amps with the ability to boost that 20 amps to 25 amps when conditions are right. That's like getting a free 65 watt solar module!

If the IPN-Remote display is ordered as an option here's how I'd install the 2512i-HV. Since the 2512i-HV is 2.75" thick and most wall mounting locations allow a max of 2" this will limit mounting options in the living area to cabinets, and since the 2512i-HV only displays the batteries state of charge via blinking LED, I'd install the 2512i-HV in the belly or dry storage compartment of the RV with the new plastic wall mounting box.

The new wall mounting box only has two knock-outs for the solar (PV) in, battery out, and remote display in. It will be a tight fit squeezing the three wires in the two knock-outs if you use 8 gauge or larger wire. The new plastic wall mount box has ventilation slots on both vertical sides which is a nice feature that the old metal wall mount box did not have.

Then I'd run the IPN remotes 25 foot cable from the 2512i-HV to the living area and install the IPN remote in the wall.

The attractive black faced IPN Remote is only a little bigger than a credit card and displays battery voltage, output current (amps) and displays the batteries state of charge via blinking LED. At night the IPN remote only displays battery voltage.

Installation of the 2512i-HV is relatively easy if you read the manual. The factory default settings of the 2512I-HV are suitable for most installations. The wiring terminal block easily accepts 10 gauge AWG wire. 6 or 8 gauge wire will require ring terminals. Ring terminals will have to be filed down to fit into the terminal block.

What you need to Acquire
1 - Automotive type ATC fuse link and 30 amp fuse or circuit breaker
2-  1/2" strain reliefs for the wall mount box
