4. Setup and Installation
Follow these steps for proper setup and installation of your sump pump battery backup system.
4.1 Mounting the Unit
The unit can be securely mounted to a wall or stable surface using appropriate fasteners. Ensure the mounting location allows for adequate ventilation around the unit.
Video: This video illustrates the simple mounting process of the EGSCATEE 2500W Sump Pump Battery Backup System to a wall and the connection of battery cables.
4.2 Battery Connection
Connect the provided battery cables to a 12V deep cycle battery. Ensure the red cable connects to the positive (+) terminal and the black cable connects to the negative (-) terminal. Secure the connections tightly. Note: The battery is not included and must be purchased separately.
4.3 Sump Pump and AC Power Connection
Plug your sump pump(s) into the AC outlets on the unit. The unit can power up to 3 primary sump pumps simultaneously, provided their combined current draw does not exceed 16.6 Amps (2500W). Then, plug the unit's AC power cord into a standard wall outlet.

4.4 Battery Type Selection
Before turning on the inverter, select the appropriate battery type using the switches on the unit. Refer to the table below for settings. This ensures optimal charging and extends battery life.
| Switch 1 | Switch 2 | Battery Type | Bulk/Absorption (V) | Float (V) |
|---|---|---|---|---|
| OFF | OFF | GEL | 14.2V | 13.6V |
| OFF | ON | AGM/SLA | 14.4V | 13.6V |
| ON | OFF | Flooded/Wet | 14.7V | 13.6V |
| ON | ON | LiFePO4 | 14.6V | 14.6V |

5. Operating Instructions
Once installed, the system operates automatically to provide continuous power.
5.1 Power On/Off
After all connections are made and the battery type is selected, turn on the unit using the ON/OFF switch. The green power LED should illuminate.
5.2 Operating Modes
The system operates in two primary modes:
- Charge Mode: When grid power is available, the unit acts as a 25A quick charger, recharging the connected 12V battery. The charging indicator will show the charging status.
- Inverter Mode: In the event of a power outage, the unit automatically switches to inverter mode within 12 milliseconds, drawing power from the battery to supply 120 VAC to the connected sump pump(s) and other devices.
Video: This video demonstrates the seamless transition between Inverter Mode (battery power during outage) and Charge Mode (grid power charging battery) of the EGSCATEE 2500W Sump Pump Battery Backup System.
