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 SB3024DiL will manage up to a 20A DC load output and provides basic battery and solar data through its onboard display. 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 IPNNetwork 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 SB3024DiL-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.
