This manual provides instructions for the Dometic Enerdrive 12V True Sine Wave Inverter series (1000W and 2000W). These units provide AC power and 5V USB power for homes, boats, caravans, and vehicles. Important: All wiring should be performed by a certified technician. The unit must be installed in an area with at least 75mm of clearance for ventilation and must not be installed in corrosive environments or zero-clearance compartments.
Product Description
The package includes the inverter base unit and the owner's manual. The front panel features AC output sockets, a USB output, an On/Off switch, and a remote plug. The rear panel contains the fan opening and DC input terminals (Positive/Negative).
Installation
Proper installation is critical for safety and performance. Follow these steps:
- Mounting: Choose an appropriate location. For RVs, mount horizontally. For indoor use, mount in any direction except with the DC input panel facing downwards.
- Wiring: Use low-resistance wire for all DC connections. EN1110S requires a minimum 35mm² wire; EN1120S requires a minimum 70mm² wire. Maximum cable length is 1.5 meters.
- Fuse/Circuit Breaker: A DC-rated fuse or circuit breaker must be installed on the positive line. EN1110S requires a minimum 150 Adc; EN1120S requires a minimum 250 Adc.
- Grounding: The chassis must be grounded properly using the ground stud located near the DC input terminal.
- DC Connection: Connect the negative cable to the battery negative terminal and the positive cable through the fuse/breaker to the battery positive terminal.
Operation
Turning ON/OFF USB only: Press and hold the Power/Select button for 1 second until a single beep sounds. The display will show USB, and the status LED will turn green. This mode saves battery power if AC is not required.
Turning ON/OFF 230 VAC and USB: Press and hold the Power/Select button for 2 seconds until 2 beeps sound. The display will show battery voltage and output power. The status LED will turn green.
Troubleshooting
The inverter uses error codes to indicate issues:
- E01: Input under voltage. Recharge battery immediately.
- E02: Input over voltage. Check battery voltage or external chargers.
- E03: Overload or short circuit. Reduce load and restart.
- E04: Internal temperature high. Turn off and wait 15 minutes.
- E05: Input voltage low. Recharge battery.
- E06: Load close to overload limit. Reduce load.
- E07: Internal temperature high/ventilation blocked. Reduce load and check ventilation.
Specifications
The Enerdrive Inverter series operates on a 12V DC input (10.5 - 15.5 VDC range). The 1000W model provides 4.3A AC output, while the 2000W model provides 8.7A AC output. Both models feature a 5V, 750mA USB output and operate within a temperature range of 0°C to 40°C.
