ACOPOWER Midas 40A MPPT Solar Charge Controller | 12V/24V with Temperature Sensor

The ACOPOWER Midas 40A MPPT Solar Charge Controller delivers 99.5% tracking efficiency and 98% peak conversion efficiency in a die-cast aluminum housing — built for 12V/24V off-grid systems with full multi-chemistry battery support and automatic temperature compensation, priced at $220.00.

• 99.5% MPPT Tracking Efficiency — Continuously locks onto the solar panel's maximum power point to extract available wattage — useful in partial shade and low-light conditions.
• 98% Peak Conversion Efficiency — High conversion rate reduces energy lost as heat and increases the amount stored in your battery bank — useful for systems running close to their capacity ceiling.
• Auto 12V/24V Detection — Automatically identifies system voltage on connection — no manual configuration needed when deploying across multiple builds or swapping battery banks.
• Multi-Chemistry Battery Support — Compatible with sealed, gel, flooded, lithium-ion, and LiFePO4 batteries with dedicated load control methods for each.
• 4-Stage Charging Algorithm — Bulk, Boost, Float, and Equalization stages deliver a complete charge cycle that supports battery capacity return and service life over time.
• Temperature Sensor Included — Automatic temperature compensation adjusts charge voltage based on ambient conditions — helps reduce overcharging in heat and undercharging in cold.
• Negative Ground Design — Compatible with the standard negative ground convention used in most RV, marine, and off-grid systems — plug-and-play with existing wiring.
• Full Protection Suite — Includes protection against reverse polarity, overcharging, over-discharging, overload, short-circuit, and reverse current.
