Solar Charge Controller with Boost MPPT, Voltage Adjustable, Waterproof, with Display This boost MPPT solar charge controller converts solar panel input into a controlled charge for batteries where panel voltage can be lower than the battery charging voltage. It supports PV input from 24 to 85 V and up to 200 W, offering flexible placement of panels and reliable, adjustable charging for a range of off grid applications. Key benefits MPPT boost function: extracts more usable power from solar panels and allows charging highervoltage batteries from lowervoltage arrays, solving compatibility issues when panel voltage is limited. Adjustable charging voltage: set the target charge voltage to match the battery or system requirements, avoiding overcharge or undercharge and extending battery service life. Waterproof, durable design: weather resistant housing and sealed connectors let you install the controller outdoors or in exposed locations with confidence. Onboard display: shows operating status and key parameters so you can monitor input voltage, charging voltage, and basic performance at a glance. Simple integration: compatible with PV arrays in the 24 to 85 V range, with a maximum solar power handling of 200 W. Features and performance Function: Boost MPPT solar battery charge controller that uses maximum power point tracking to optimize energy harvest, then steps voltage as required to charge the battery. Input range: PV array voltage accepted from 24 to 85 V. Power rating: supports up to 200 W of solar input. Voltage adjustment: userconfigurable charge voltage to suit the connected battery or system voltage target. Display and controls: integrated visual display for real time monitoring and straightforward setup. Environmental resistance: designed for use in outdoor or semiexposed installations where moisture protection is required. Practical compatibility and installation notes Works with solar arrays whose open circuit and operating voltages fall within the 24 to 85 V window and with systems where total PV power does not exceed 200 W. Adjustable output makes the controller suitable for charging batteries or battery banks that require specific charge voltages. Compact form factor and sealed housing allow flexible mounting on poles, bulkheads, or inside small enclosures. Standard wiring terminals simplify connections to the array and battery. Use scenarios Remote cabin or tiny house: Install the controller with a small roof array whose voltage is lower than the battery bank. The boost MPPT function enables reliable charging even when panel placement is constrained. Vehicle or boat auxiliary charging: Charge an auxiliary battery bank from panels mounted in limited space where producing panel voltage is difficult. The adjustable charge voltage lets you align charging behavior to the battery requirements. Off grid lighting or monitoring station: Power a battery for lights or telemetry where panels face variable sun and wiring runs require flexible panel placement. The display allows quick verification of system status during inspections. Why choose this controller for your system Solves the common mismatch between panel voltage and battery voltage with MPPT boost capability. Provides adjustable charging to match battery needs while giving clear feedback via the built in display. Rated for 24 to 85 V input and 200 W power, making it suitable for many small to medium off grid setups where reliability and flexibility matter. What is included Boost MPPT solar charge controller with onboard display and sealed housing. User manual with basic setup and adjustment instructions. Note: Confirm that your PV array voltage and total power fall within the specified input range and 200 W limit before installation.
