Meet the SB2512iX-HV, our most affordable MPPT controller option available for off-grid electrification or use with off-grid inverters (for AC load). The SB2512iX-HV's additional features, such as an auxiliary output for charging a second battery, make it suitable for many applications, including RVs and Marine. The SB2512iX-HV can manage a 25A load output for small off-grid electrification applications. When programmed with an IPN Pro Remote or UCM, it will provide dusk-to-dawn load control for PV street lighting. It is compatible with FLA, AGM, and Gel batteries, and Lithium batteries when programmed by an IPN ProRemote. Its IPN Network interface can communicate with other Blue Sky Energy charge controllers as a single charging system, allowing increased flexibility and optimization in system design.
