The SB2512iX-HV(-Li) features our patented MPPT technology, a second auxiliary battery output, and an IPN connector for remote display or Bluetooth adapter is ideal for RVs and Marine. The SB2512iX-HV(-Li), can manage a 25A @12V DC Load Output for medium size off-grid electrification applications and with an IPN ProRemote, BT Connect, or UCM, the DC Load Output can be programmed with its dusk-to-dawn load control for PV street lighting. 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. The basic version SB2512i-HV has been discontinued.

SB2512iX-HV-Li default programmed for 4S LiFePO4(*)

(*) programmable for different types of batteries with IPN ProRemote display, UCM, BT Connect, or ProTouch display.

1: 36-cell panels are typically referred to as “12V panels” providing Vmp/Voc of ~18V/22V at STC, 60-cell panels refers to "20V panels" (Vmp/Voc ~30V/37V), 72-cell panels refers to "24V panels" (Vmp/Voc ~36V/44V).
2: Factory default voltages unless programmed with an IPN ProRemote display, BT Connect, ProTouch, or UCM.
