12/24VDC 40A
Description
This solar charge controller is typically a device for solar charge regulation and discharge output control, adopted the latest MPPT charge algorithm technology for max use of solar power. LCD screen display, parameter settings allowed, mainly used in small and medium size solar DC power system.
■Automatically detects 12V/24V/36V/48V DC system voltages
■Deep Cycle Sealed, Gel, Flooded, and Lithium battery Compatible
■Innovative MPPT technology with high tracking efficiency up to 99% and peak conversion efficiency of 98%
■Electronic protection against reverse polarity, short circuit, high temperature and overvoltage
■LCD screen displaying system operation information, customizable parameters, and error codes
■Features diverse load control; also capable of charging over-discharged lithium batteries
■RS485 port allows the Controller to communicate with the external Bluetooth module, which can pair with the Helios Bluetooth cellphone app
■Controller Parallel connection support
