6. Operating Instructions

6.1 Powering On/Off

• Power On: Ensure all connections are secure. Turn on the battery breaker first, then the AC input breaker (if applicable), and finally the PV input breaker. Press the power button on the inverter.
• Power Off: Reverse the power-on sequence. Turn off the PV input breaker, then the AC input breaker, and finally the battery breaker. Press and hold the power button to shut down the inverter.

6.2 Charging Modes

The inverter offers four selectable charging modes:

• Solar Only: Charges batteries exclusively from solar power.
• Mains Priority: Prioritizes charging from the utility grid, using solar only when grid power is unavailable.
• Solar Priority: Prioritizes charging from solar power, using the utility grid only when solar power is insufficient.
• Mixed Mains/PV Charging: Utilizes both solar and utility power for charging.

These modes can be configured via the inverter's display or the monitoring application.

6.3 Output Modes

The inverter supports two output modes:

• Utility Bypass: Loads are powered directly by the utility grid.
• Inverter Output: Loads are powered by the inverter (from batteries or solar).

The inverter provides an uninterrupted power supply function, seamlessly switching between modes.

6.4 Battery Compatibility and Activation

The inverter is compatible with various battery types, including AGM, Gel, Lead-acid, Lithium-ion, and LiFePO4. It also supports batteryless operation. For dormant Li-ion batteries, activation can be triggered by either mains power supply or photovoltaic power supply access.

Figure 6: The inverter provides 10000W AC output (20000W peak) and can simultaneously output 110Vac and 220Vac, making it compatible with a wide range of household appliances.

7. Monitoring and Control

The inverter can be monitored and controlled via the SmartESS App. A Wi-Fi/GPRS data acquisition module is required for this functionality and must be purchased separately.

Figure 7: The SmartESS App allows for remote monitoring and control of the inverter. The Wi-Fi/GPRS module (Q2721100111238) is optional and sold separately.

Download the SmartESS App from the App Store or Google Play. Once the Wi-Fi module is installed and configured, you can view real-time system data and adjust settings remotely.
