WALTON WSOL-CC-20A Solar Charge Controller
Power larger home solar arrays, DC appliances, and battery banks with the WALTON WSOL-CC-20A Solar Charge Controller. Designed for higher current loads up to 20 Amps, this heavy-duty PWM controller manages solar input for 12V or 24V battery systems using a 3-stage charging process.
Equipped with an intuitive LCD screen, programmable timer controls, and dual 5V/2A USB ports, it lets you monitor and adjust float charging levels, low voltage disconnects (LVD), and load timing. Dual MOSFET reverse-current protection keeps power moving safely into the battery bank while preventing overnight back-feed loss.
20A High Power Rating: Handles double the solar panel capacity and DC load output compared to 10A models.
12V/24V Smart Auto Adaptation: Seamlessly switches internal profiles based on the connected battery voltage.
Interactive LCD Screen: Offers clear visibility into charging status, battery levels, and custom voltage settings.
Dual MOSFET Reverse Current Defense: Minimizes heating while blocking current backflow during non-sunny hours.
