ExpertPower 40A MPPT Solar Charge Controller | 12V / 24V Auto-Select Intelligent Regulator | Max PV Input 100V | Gel Sealed Flooded and Lithium LiFePO4

The 40A MPPT charge controller is part of our top controller models. It's designed to be compatible with solar systems under 520W for 12V or under 1040W for 24V. Aside from being compatible with all existing lead-acid battery types and lithium batteries, it's capable of resetting a battery's triggered BMS to ensure your system maintains a smooth and efficient transition between a BMS interrupt and system reset. An optional Bluetooth module or LCD screen can be attached to provide more visual assessment of solar system data.

• MPPT: The controller utilizes modern solar technology to maximize your solar array's power generation by over 20% through sophisticated tracking and capture compared to PWM.
• System Versatility: The unit auto-detects 12V/24V systems and adapts to the battery chemistry required including lithium batteries among all typical lead-acid chemistries such as AGM, Gel, Flooded, and more through its user-defined functions. The optional bluetooth app lets you take complete control of your system's for the highest level of maintenance and capability.
• BMS-capable: Most Lithium batteries require BMS boards to protect the battery but the controller itself is able to operate with BMS-less batteries through its diverse set of protection capabilities including over-voltage, over-charge, low-voltage, deep discharge, and over-temperature compensation.
• Premium Quality: The controller is built on an industrial-grade chassis, able to withstand all sorts of abuse in harsh conditions-- IP32 rating.
• ExpertPower: All ExpertPower Charge Controllers operate at their full potential with an ExpertPower branded battery and solar panel.
