Instruction Manual

Sku: TruPower-CContr-12V30A

Solar Charge Regulator is designed to control the charging from solar panel into battery, and the

power draw from the battery to outputs.

Feature

 TPS555 Solar Charge Regulator is able to handle charge and discharge from either 12V battery or

24V battery (Different Model required).

 It provides over-charging, over-discharging, short circuit, over-load and reverse polarity protection.

Therefore keep the whole solar system at proper working condition.

 This solar charge regulator uses the latest Microcomputer-chip to realize intelligence control

 PWM (pulse width modulation) charging circuit is used for higher efficiency

 Big LCD display available for easy monitoring

  Nicole SimmonsAug 1, 2025
  If your Silicon Solar Inverter load isn't working, here's what to check: 1. Ensure the load switch is ON; the LCD should indicate this. If it is off, press the switch until LCD shows. 2. Verify the battery connection: it should be secure, of correct polarity and connected to the charge regulator. 3. Correct any reversed load polarity. 4. If over-discharge protection is active, disconnect the load and fully recharge the battery. 5. Inspect for short circuits or overloads, ensuring the load current doesn't exceed 30A. If all is okay, press the switch.
