The SB3024 charge controller family, featuring our patented MPPT technology, handles up to 800W of PV power at 24V. This controller is ideal for RVs and Marine applications with its auxiliary output for charging a second battery and can utilize a remote display with its IPN connectivity. The SB3024iL or DiL will manage up to a 20A load output for off-grid electrification or telecommunication systems. When programmed with the IPN Pro Remote or UCM, it can be used for PV street lighting, utilizing its smart dusk-to-dawn load control feature. 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.
