1. Introduction
This manual provides essential information for the safe and efficient operation of your Giandel 1200W Power Inverter with an integrated 20A Solar Charge Controller. This device converts 12V DC battery power to 120V AC household power, making it suitable for various applications including RVs, trucks, and off-grid solar systems. Please read this manual thoroughly before installation and use.
2. Safety Information
WARNING: Failure to follow these safety instructions may result in injury, damage to the inverter, or damage to connected devices.
- Ensure the battery voltage is 12V and fully charged before connecting the inverter.
- Do not expose the inverter to direct sunlight or extreme temperatures. Keep it in a cool, dry, and well-ventilated environment.
- Disconnect the positive battery terminal before performing any wiring to the inverter.
- Do not use the inverter with appliances that draw more wattage than the inverter can provide (1200W continuous, 2400W peak). Overloading can damage the inverter and the appliance.
- The inverter features multiple safety protections: over voltage, low voltage, overload, short circuit, over heat, and reverse polarity (fuse protected). These functions will trigger a warning and shutdown to protect the inverter.
- Ensure proper grounding of the inverter.
- Do not leave the power inverter in the ON position when your vehicle engine is off to prevent battery drain.

4.4 Battery Type Selection
The inverter has a switch to select the battery type for optimal charging via the solar charge controller.
- Locate the 'Battery Select Switch' on the inverter's front panel.
- Set the switch to 'GEL' for Gel batteries or 'LEAD ACID' (SLA) for Sealed Lead Acid batteries, according to your battery type.
5. Operating Instructions
5.1 Powering On/Off
- After all connections are secure, press the 'POWER' button on the inverter's front panel or the remote control to turn the unit ON. The 'POWER' indicator light will illuminate.
- To turn OFF the inverter, press the 'POWER' button again.
5.2 Using AC Outlets and USB Port
- Once the inverter is ON, plug your 120V AC appliances into the two AC outlets.
- Connect USB-powered devices to the 2.4A USB port for charging.
