WATTSTUNDE® 10 A solar charge controller PEKO10

Reliable and efficient second-generation solar charge controller for small 12V systems

The WATTSTUNDE® PEKO10 charge controller automatically detects the system voltage and charges your battery according to its voltage and type at all times with an optimal charging curve. Additionally, the integrated USB port provides a direct charging function, allowing you to charge your devices such as mobile phones or tablets directly from the charge controller.

Unlike simple shunt charge controllers that only fully charge, the PEKO charge controller with PWM technology gently charges your battery by continuously adjusting the current battery voltage using pulse width modulation (PWM).

Optimal protection against overcharging and deep discharging - solar module power up to 170Wp (12V) can be connected!

With the PEKO charge controller, you can expect high reliability, state-of-the-art technology and ease of installation at an optimal price-performance ratio.

An optional load output can be used to connect 12V devices. Furthermore, your battery is automatically protected from deep discharge by the integrated low-voltage discharge (LVD) protection of the charge controller.

Only when the voltage reaches a certain level again are the consumers automatically switched back on (LVR). This ensures that your battery is never deeply discharged.

When the night light function is activated, the loads/consumers are automatically switched on only from dusk until sunrise. During the day, the loads/consumers remain off. The charge controller measures the incoming module voltage and thus detects the daytime state. When the module voltage drops (5-10V), the charge controller detects dusk and switches to the night light function, switching the loads/consumers on.

When the solar module open-circuit voltage reaches a value >15V, the charge controller detects daylight and switches off the loads / consumers.
For example, it could be used to power a night light; the lamp switches on at dusk and switches off again at dawn.
