Flexible, reliable, and ready to work! The SB1524iX, featuring our patented MPPT technology, with a second battery output and IPN connector for remote display, is ideal for RVs and Marine applications. The SB1524iX can manage a 20A at 12V (or 15A at 24V) load output for small off-grid electrification applications. When programmed with an IPN ProRemote or UCM, it is also ideal for PV street lighting with its dusk-to-dawn load control. It can also charge Lithium batteries when programmed with the IPN Pro Remote. 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.


The perfect controller for a variety of applications, including marine, RV, Off-Grid, PV street lighting and PV traffic signals.
