Solar PWM controller SY3024H 12-24V/30A+USB for Pb batteries

Product detailed description

The PWM controller SY3024H allows charging of lead-acid batteries with a current of up to 30A and connection of PV panels with an output voltage of max. 25V(12V) or 50V(24V) up to a power of 360W(12V) or 720W(24V). It is equipped with an LCD display for setting and displaying operating parameters.
PWM solar controllers connect solar panels directly to the battery being charged, and once the set or given terminal voltage of the battery is reached, further regulation is handled by pulse limiting-interruption of the current. This happens at a frequency of units to tens of Hz, and in some controllers it is indicated by a blinking LED labeled "charge" or "solar". Controllers are suitable for panels with a system voltage matching the battery voltage, otherwise losses occur, where part of the power is wasted due to an unsuitable V-A characteristic of the panel.
