12V/24V automatic identification charger, lead-acid battery (lithium battery, Ni-MH battery is not available) solar charge controller, only supports photovoltaic solar panels as a charging source. When the charging battery is 12V, choose the 17-22V solar panel; when the charging battery is 24V, choose the 30-42V solar panel for charging. Charging with mismatched voltage will damage the controller. Charging and discharge status display, cumulative power generation and discharge query, temperature display. Light control delay control, adjustable charge and discharge parameters, with power-off memory function. Built-in over the current, short circuit, open circuit, reverse connection, protection; self-recovery protection, does not damage the controller and extends the service life.
