Weight: 4.58 oz Item Description Innovative MPPT Design, up to 99% efficiency and Operate with Battery when Battery is 0 Volt: Renogy MPPT technology is with a high tracking efficiency of up to 99% and peak conversion efficiency of 98%. It is the best charging solution even in cloudy environments where the max power point of the solar panels will fluctuate all day. Even when the battery is dead (at 0 volt), the controller can activate it with small current and bring it to life. 12/24 Automatically Detect and Multiple Battery Adaptation: Capable with and automatically detects 12V or 24V DC system voltages. Perfect for Sealed Lead Acid, GEL, Flooded Battery. Especially design of user mode to let user custom Lithium Battery parameter manually to solve the common issue of voltage matching of lithium battery. 4-Stage Safely Charging: Features 4-stage charging (Bulk, Absorption, Float, and Equalization) of Lead Acid Batteries and 2-stage charging (Bulk and Absorption) for Lithium batteries as well as Lithium Reactivation. Intelligent charging method prolong your battery?s life. Extremely Safe: Full system protection from program and insulated shell safeguards your solar system. The intelligent self-diagnostic capability can assess and protect against reverse polarity, battery overcharging, battery over-discharging, overload, short-circuiting, overheating, and reverse current. The UL certificated Rover charge controller with insulated shell prevents you from accident and keep your solar system in safe in high temperature. Easy to Understand and Set up: LCD screen and multiple LED indicators for displaying system operation information, customizable parameters, and error codes, you can understand the charging status and set the parameter better and easier with the display. Easy to mount design and mounting brackets are included for convenient set up. You can connect DC appliances directly to the load terminals, 5 load modes for better load management, make it easy for you to use your device. Comes with Bluetooth Module BT-2(Version 2) or BT-1(Version 1): You can monitor consumption or custom parameter directly from DC Home on your phone. RJ45 communication port allows the Renogy Rover controller to communicate with the Renogy BT-2 Bluetooth, which will enable you to monitor the status and productivity of your panels through the Renogy DC Home App. Mute and Excellent Heat Dissipation: Integrated heat sink, instead of cooling fan, provides a 0 dB surrounding for relax and ensures maximum charging efficiency and safety.
