Solarmax 20amps Solar Charge Controller PWM

Charge Regulation: Manages power flow from panels to battery, preventing damage. Current Rating: Handles up to 20 Amps of current, suitable for systems with panels providing up to ~400W (12V) or ~800W (24V). Technology: PWM (Pulse Width Modulation): Cost-effective, good for smaller setups, uses series switching. Battery Compatibility: Works with 12V/24V systems, supports AGM, Gel, Lead Acid, LiFePO4. Display & Control: LCD screen shows status (voltage, current, battery health) and allows settings adjustment via button. Protection: Built-in safety features: overcharge, over-discharge, reverse polarity, short circuit, over-temperature. Load Output: DC load terminals for powering lights or small appliances, often with Low Voltage Disconnect (LVD). USB Ports: Dual USB ports (5V) for charging mobile devices.
