The AIMS Power 40 AMP Solar Charge Controller 12 / 24 / 36 / 48 VDC MPPT is built for higher-efficiency solar battery charging across compatible 12V, 24V, 36V, and 48V systems. Using Maximum Power Point Tracking technology, this controller helps harvest available solar energy from the PV array and regulate it for battery charging with reduced power loss. It supports 40 amps maximum battery current, rated PV input up to 500W at 12V, 1000W at 24V, 1500W at 36V, and 2000W at 48V, and 4-stage charging for supported battery types. LED indicators, an LCD display, RS485 computer monitoring, heatsink cooling, and built-in protection features make this controller a practical choice for more advanced off-grid, mobile, marine, and property-based solar power systems.
This AIMS Power charge controller uses MPPT technology to track the available peak power from the solar array and regulate charging to the battery bank, helping improve charging efficiency compared with basic controller designs when properly matched to the system.
The controller supports multiple battery system voltages, making it suitable for properly configured solar systems ranging from smaller 12V setups to larger 48V battery banks.
Supported battery types include gel, sealed, AGM, flooded, lithium, and user-defined settings, with 4-stage charging that includes bulk, absorption, float, and equalize modes where applicable.
The RS485 port supports computer monitoring of charge controller functions, while the heatsink-cooled metal enclosure is designed for fan-free thermal management and marine-coated protection in demanding environments.
This 40 amp MPPT solar charge controller is designed for properly sized solar battery systems that need efficient charging, broad voltage compatibility, and stronger system monitoring.
With RS485 monitoring, LED indicators, an LCD display, and multiple protection features, this AIMS Power controller supports practical solar charging control for off-grid, mobile, marine, and property power applications.
