The WhisperPower Solar Charge Controller PWM 12 V – 20 A is a highly efficient device for managing solar energy in off-grid setups. By converting PV solar energy to charge batteries effectively, it ensures optimal usage of harvested solar power. The added feature of protecting the battery from overcharge and over-discharge (for the LD model) adds a layer of reliability and safety, making it an excellent choice for anyone looking to optimize their solar energy system.
- Suitable for every type of battery: Gel, AGM or open lead
- Plug and play connectors for panel, battery and 12 V load
- Automatic shut down if battery voltage (too) low
- Can feed up to 20 amps / 450 Watts solar power to the batteries
- Temperature compensation as standard
- LEDs battery indicator and load status
