Renogy 40A MPPT Solar Charge Controller 12V/24V with Bluetooth

Key features

【Advanced MPPT Technology】 This Mppt Solar Panel charge controller adopts innovative MPPT technology with Maximum Power Point Tracking, delivering a high tracking efficiency of up to 99% and peak conversion efficiency of 98%. The solar charge controller is the best charging solution even in cloudy environments where the max power point of the solar panels will fluctuate all day, 【12V/24V Automatically Detect】 This Mppt charge controller automatically detects 12V or 24V DC system voltages.

And the LCD screen and multiple LED indicators display the solar charging and battery operation information, customizable parameters, and error codes. Error code detection for easy self diagnoses, 【Full System Protection】 Meant to safeguard your system, the self-diagnostic capability of this solar controller can assess and protect against reverse polarity, battery overcharging, battery over-discharging, overload, short-circuiting, overvoltage and reverse current.

And die-cast aluminium design ensures excellent heat dissipation, 【4-Stage Safely Charging】 The charge controller features 4-stage charging (Bulk, Absorption, Float, and Equalization) of Lead Acid Batteries and 2-stage charging (Bulk and Absorption) for Lithiuim batteries as well as Lithium Reactivation. This solar controller can reactivate and charge over-discharged lithium-ion batteries.

Compatible with various Deep Cycle battery options. High accuracy, Automatic focusing MPPT tracking charging and bidirectional focusing tracking, 【Remote Monitoring & Diverse Load Control】 Package includes a 40A MPPT charge controller and a BT2 bluetooth module.

RS485 communication port allows the Renogy Rover controller to communicate with Renogy BT-2 Bluetooth module that will enable you to monitor the status and productivity of your panels through the Renogy App. You can Connect DC appliances directly to the optional Load Terminals and monitor consumption or set up timer controls directly from the MPPT solar panel contro
