Great for mid-sized systems, the SB3024 charge controller family, featuring our patented MPPT technology, handles up to 800 W of PV power when charging 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 will manage up to a 20A DC load output. When programmed with the IPN ProRemote, BT Connect, 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.

OPTIONAL: The DUO Option upgrade allows an SB3024iL-DUO to provide PWM charge control for hydroelectric, wind, or similar DC generators that require diversion-type charge control while at the same time providing MPPT charge control for the main PV system.
