Instruction Manual
The TPS-555 Solar Charge Regulator is designed to control the charging from the solar panel/s into the
battery, and the power draw from the battery to the loads.
Feature
TPS555 Solar Charge Regulator is able to handle charge and discharge from a 12V battery bank.
It provides over-charging, over-discharging, and over-load protection. Therefore keeping the whole
solar system at a proper working condition.
PWM (pulse width modulation) charging circuit is used for higher efficiency
