Charge Controllers
5A / 10A / 20A Charge Controllers
All our solar charge controllers are designed for charging 12V battery systems without disrupting your existing power supply. It incorporates MCU (Modular Central Unit) and SCM (Smart Charge Manager) technology to intelligently charge your battery and ensure maximum capacity and length of life.
Features
- Fully automated operation
- 3 pairs of terminals (input, battery, output)
- LEDs to indicate charging, output and battery capacity
- Temperature sensor
- Replaceable fuse to protect the system from damage
- Metallic heat sink
- Mounting holes for ease of installation
Specific Attributes
- High precision voltage recognition and PWM (Pulse Width Modulated) algorithm to ensure charging is as efficient as possible whilst protecting your battery life
- Temperature sensor to ensure your battery is charged optimally at all temperatures
- Protection from over-charging and deep-discharging in order to maintain the longest life for the batteries
- Cut out to prevent damage if battery or panel are incorrectly connected
- Protection for the entire system against a short circuit in or other excess current to the output
- Protection for the entire system against short circuit in the solar panel
- LED indication of battery capacity including low-charge warning
- LED indication to show when solar panel is charging the battery
- Buzzer to warn of incorrect battery connection
