PowMr 10200W Solar Inverter User Manual

1. Introduction

The PowMr 10200W Solar Inverter is a high-capacity, off-grid pure sine wave inverter designed for reliable power conversion from 48V DC to 220-230V AC. It integrates a 160A MPPT charge controller, supporting a maximum PV array power of 5400W. This versatile unit is suitable for various applications including homes, cabins, RVs, boats, and off-grid backup systems. It is compatible with both 48V lead-acid (Seal, AGM, Gel, Flooded) and lithium batteries.

Key features include dual PV input for uninterrupted power supply, dual AC output delivering up to 10200W, and multiple charging and output modes to optimize energy management. The inverter also incorporates comprehensive 360° safety protection against short-circuit, over/under-voltage, overload, and backfeed. An intuitive RGB light system indicates the current working mode of the inverter.

2. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your PowMr Solar Inverter. Ensure all connections are secure and follow local electrical codes.

2.1 Unboxing and Components

Upon unboxing, verify that all components are present as listed in the packing list. The package typically includes the 10200W 220VAC Solar Inverter, an instruction manual, MC4 connectors, ring terminals, and other accessories.

2.2 Wiring Connections

Follow these steps for wiring the inverter. Always ensure the system is de-energized before making any connections.

1. Battery Connection: Connect the 48V battery first. Ensure proper polarity (+ to + and - to -).
2. AC Input Connection: Connect the AC input wires (Live, Neutral, Ground) from your utility grid or generator to the designated AC input terminals.
3. AC Output Connection: Connect your AC loads to the main AC output terminals. The inverter supports dual AC outputs.
4. PV Input Connection: Connect the solar panel array to the PV input terminals. Ensure correct polarity and voltage within the specified range (Max PV Array 5400W, Max PV Input VOC: 500V DC).

3. Operating Instructions

The PowMr Solar Inverter offers flexible operating modes to suit various energy needs.

3.1 Multiple Charging Modes

The inverter supports three optional charging modes:

• Solar First (CSO): Prioritizes solar power for charging.
• Solar & Utility (SNU, default): Uses both solar and utility power for charging.
• Only Solar (OSO): Charges exclusively from solar power.

3.2 Output Modes

Three output modes are available to ensure uninterrupted power:

• Solar First: Prioritizes solar power for loads.
• Mains First: Prioritizes utility grid power for loads.
• SBU Priority: Prioritizes solar, then battery, then utility for loads.

3.3 RGB Light Indicators

The PowMr Hybrid Inverter's logo displays different colors to indicate its working mode:

• White Light: Stationary Mode
• Purple Light: PV Mode
• Red Light: Battery Mode
• Blue Light: Utility Mode

3.4 Dual Output Functionality

The inverter features dual AC outputs. In areas with frequent power outages, you can set a higher battery voltage for critical loads to retain more power for use in the event of a blackout. When the battery voltage falls below a set value, the main load port stops working, and only the second load port remains active. When the battery voltage is higher than the set value, the main load port operates again.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your solar inverter. Keep the inverter clean and free from dust. Periodically check all wiring connections for tightness and signs of wear or corrosion. Ensure adequate ventilation around the unit to prevent overheating. Refer to the full instruction manual for detailed maintenance procedures and schedules.

5. Troubleshooting

If you encounter issues with your inverter, consult the troubleshooting section of the comprehensive manual for common problems and solutions. Basic troubleshooting steps often involve checking connections, verifying battery and PV voltages, and observing error codes displayed on the LCD screen. For persistent issues, contact customer support.
