Charge controller from ROZA TOYS, suitable for installations up to 20A at 24V. It is of PWM type.
The PWM charge controllers simply connect the photovoltaic panel to the battery (12/24/48V), functioning as switches. When the switch closes, the voltage of the panel equals that of the battery.
The voltage of the array that the PWM controller can accept depends on the battery voltage and is low, usually one to two panels of 100/200Wp in series. This relates to a low charging current compared to the capabilities of a MPPT charge controller.
The PWM charge controllers are ideal for smaller systems where system efficiency is not such an important factor and for solar collectors with a maximum power voltage (Vmp) of up to 18V for charging a 12V battery.
