The PowMr POW-SunSmart 10K is a high-performance 10KW split-phase hybrid solar inverter designed for both on-grid and off-grid applications. It features dual MPPT (Maximum Power Point Tracking) technology with a 200A solar charger, providing efficient power conversion and management for 48V battery systems, with 110V and 220V AC output capabilities. This manual provides essential information for the safe installation, operation, and maintenance of your inverter.

2. Safety Information

• Read all instructions and warnings in this manual before installation and operation.
• Installation must be performed by qualified personnel in accordance with all local electrical codes.
• Ensure the inverter is disconnected from all power sources (PV, battery, utility) before performing any maintenance or wiring.
• Do not disassemble the inverter. There are no user-serviceable parts inside.
• Avoid exposing the inverter to rain, snow, or liquids. Install in a dry, well-ventilated area.
• The open circuit voltage of the PV panel in series connection must remain below 500V. Over-voltage will cause damage to the inverter and is not covered by warranty.

6. Setup

6.1 Wiring Diagrams

The PowMr POW-SunSmart 10K supports both Split-Phase and Single-Phase configurations. Ensure all wiring is done by a qualified electrician.

Split-Phase Mode (120V/240V)

Notice: The open circuit voltage of PV panels in series connection must be below 500V. Over-voltage will cause damage to the inverter. Damage caused by improper configuration is not covered by warranty.

Single-Phase Mode (120V)

Notice: The open circuit voltage of PV panels in series connection must be below 500V. Over-voltage will cause damage to the inverter. Damage caused by improper configuration is not covered by warranty.

6.2 Battery Compatibility

The inverter is compatible with 48V Lead-acid and Lithium batteries. It also supports batteryless operation, where the inverter can power loads directly from the PV array or AC grid without a battery connected. The battery charging current setting range is 0-200A.

A dual activation function allows the inverter to trigger the activation of a dormant Li-ion battery via either mains or photovoltaic power supply access.

7. Operating Instructions

7.1 Time-Slot Charging/Discharging Function

The POW-SunSmart series is equipped with a time-slot charging and discharging function, allowing users to set different charging and discharging periods according to local peak and valley tariffs. This optimizes the use of utility power and PV energy, helping to save electricity costs.

Notice: Before using this function for the first time, please set the local time in parameter items 54, 55. Then, you can set the corresponding time slot according to the local peak and valley tariff charges.

7.2 Display Navigation and Settings

Use the touchable keys (SET, UP/DOWN, ENTER) on the LCD display to navigate through menus and adjust parameters. Refer to the detailed diagram in Section 5.2 for key functions.

8. Maintenance

8.1 Detachable Insect-Proof Screen

The inverter features a detachable insect-proof screen to prevent insects from entering and causing internal damage. Regularly clean the screen to maintain proper airflow and prevent overheating.

8.2 Intelligent Cooling Fans

Equipped with four cooling fans, the inverter ensures efficient heat dissipation and stable operation. Keep the fan vents clear of obstructions to allow for proper airflow.

9. Troubleshooting

If the inverter is not functioning as expected, perform the following basic checks:

• No Power: Check all AC input, DC battery, and PV connections. Ensure the ON/OFF rocker switch is in the 'ON' position.
• No Output: Verify that the AC output breaker is not tripped. Check for any fault indicators on the LCD screen.
• Overload Protection: The inverter has built-in overload protection. If an overload occurs, the inverter will attempt to resume output after a delay. Repeated overloads will cause the inverter to switch off until restarted. Refer to the specifications for detailed overload thresholds and recovery times.
• Fault Indicators: Consult the LCD display and LED indicators for specific fault codes or warnings. Refer to the full product manual for a comprehensive list of fault codes and their remedies.
• PV Input Issues: Ensure PV panels are receiving adequate sunlight and connections are secure. Check PV voltage and current on the LCD display.

For persistent issues, contact PowMr customer support.

10. User Tips

• Simultaneous 110V and 220V Output: Yes, this inverter is designed to provide both 110V and 220V output simultaneously, making it suitable for a wide range of household appliances and RV setups.
• Parallel Connection: The inverter includes a 'PARALLEL CONNECTION' port. For detailed instructions on connecting multiple units in parallel, please refer to the comprehensive installation guide provided with the product or contact PowMr technical support.
• Optimizing Charging: Utilize the time-slot charging/discharging function to take advantage of off-peak electricity rates and maximize self-consumption of solar energy.
• Monitoring: Regularly check the LCD display for real-time system performance and any alerts to ensure optimal operation.
