- LED Display: Shows real-time information including battery voltage and AC output voltage.
- Switch: Controls the power to the inverter.
5. Setup
Follow these steps for proper installation and connection of your sump pump backup system.
- Battery Selection: This inverter requires a 12V GEL, AGM/SLA, or Flooded/Wet battery for backup power operation. Ensure the battery is fully charged before initial use for optimal performance.

Image: The system is compatible with 12V GEL, AGM/SLA, and Flooded/Wet battery types. The table indicates Bulk/Absorption and Float voltage settings for each battery type, typically 14.4V and 14.4V respectively.
- Connect Battery Cables: Connect the supplied red battery cable to the positive terminal of the inverter and the positive terminal of your 12V battery. Connect the black battery cable to the negative terminal of the inverter and the negative terminal of your 12V battery. Ensure connections are secure.
- Connect AC Input: Plug the provided AC cable into the AC Charge Input port on the inverter and then into a standard wall outlet (120V AC). This will initiate the battery charging process.
- Connect Sump Pump: Plug your sump pump's power cord into one of the 120V AC Output sockets on the inverter. The system is designed to power up to three sump pumps with a maximum combined wattage under 2000 watts.

- Power On: Turn on the inverter using the power switch. The LED display will show battery voltage and AC output voltage.
6. Operating Instructions
The Cantonape Sump Pump Backup System operates in two primary modes: Charging Mode and Inverter Mode, with automatic switching capabilities.
6.1. Charging Mode
When connected to AC power, the built-in 20A battery charger will automatically charge the connected 12V battery. The system employs a three-stage charging process (Constant Current, Constant Voltage, Float Charging) to ensure fast and safe charging without damaging the battery.

Image: This diagram illustrates the three-stage charging process: Constant Current Charging Mode (10A), Constant Voltage Charging Mode (14.2A), and Float Charging Mode (13.5A), ensuring efficient and safe battery charging.
6.2. Inverter Mode (Backup Power)
In the event of a power outage, the system will automatically switch from AC power to battery inverter power. This transition is seamless, ensuring continuous operation of your sump pump and other connected devices. The pure sine wave output provides stable and clean power, suitable for sensitive electronics.

The LED display provides real-time monitoring of battery voltage and AC output voltage, allowing you to stay informed about the system's status.
7. Maintenance
Regular maintenance ensures the longevity and reliable operation of your Cantonape Sump Pump Backup Battery System.
- Cleaning: Keep the unit clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Ensure the smart cooling fan and ventilation openings are not obstructed. Periodically check for dust buildup and gently clean if necessary to maintain efficient cooling.
- Battery Check: Regularly inspect battery terminals for corrosion and ensure connections are tight. Check the battery's charge level, especially if the unit has been in storage or not regularly used.
- Storage: If storing the unit for an extended period, disconnect it from the battery and store it in a cool, dry place. Ensure the battery is fully charged before storage and recharge it every few months to prevent deep discharge.
