Compact, reliable, and fully programmable: the SB3000i is ready to work! The SB3000i, featuring our patented MPPT technology, is ideal for RVs and Marine applications with a second battery output and IPN connection for remote display and networking. This controller can be programmed from its onboard display or in conjunction with an IPN ProRemote. This gives maximum flexibility when operating PV street lighting or using for small-scale off-grid electrification. Compatible with FLA, AGM, Gel, and Lithium batteries. 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, industrial, off-grid, and PV street lighting.
