WATTSTUNDE® PEKO 03 Solar Charge Controller 3 A
Reliable and Efficient Charge Controller for Small 12V Systems
The WATTSTUNDE® PEKO charge controller automatically detects the system voltage and charges your battery with an optimal charging curve at all times, according to its voltage and type.
Product Features:
- PWM control
- Multi-stage charging technology
- Low voltage disconnect (LVD)
- Overcharge protection
- Load output 3A
- 12V systems
- Self-test function
- Temperature compensation
- LED status indicator
- Over-temperature or overload protection
- Automatic shutdown in case of battery overvoltage
- Reverse current protection at night
- Short circuit protection
- Lead-acid battery
- Warranty period: 2 years
Unlike simple shunt charge controllers, which only fully charge, the PEKO charge controller uses PWM technology to gently charge your battery by continuously adjusting the current battery voltage via pulse width modulation (PWM).
Optimal protection against overcharging and deep discharge - solar module power up to 50Wp (12V) connectable!
With the PEKO charge controller, you can expect high reliability, state-of-the-art technology, and easy installation at an optimal price-performance ratio.
An optionally usable load output can be used to connect 12V consumers. In addition, your battery is automatically protected from deep discharge by consumers with the integrated low voltage disconnect (LVD) of the charge controller.
Only when the voltage reaches a certain value again will the consumers be automatically reconnected (LVR). This way, you can always be sure that your battery will not be deeply discharged.
