4. Product Overview

The Dawnice 10kW Solar Panel Kit is a robust system designed for efficient off-grid power generation and storage.

4.1. Bifacial Solar Panels

The system includes 18 pieces of 550W bifacial solar panels. These panels utilize advanced module technology, allowing them to absorb sunlight from both the front and rear sides. The back gain efficiency can reach up to 25%, meaning the maximum power output of each 550W panel can reach up to 688W under optimal conditions.

4.2. 10kW Hybrid Inverter

The 10kW hybrid inverter is UL certified and supports both off-grid operation and selling electricity back to the grid. It provides a pure sine wave output with selectable voltages of 120V or 240V and a maximum output power of 10000W. The inverter can also be connected to a diesel generator for additional power input.

4.3. 16kWh Lithium Batteries

The system includes a 16.07kWh lithium battery pack (51.2V 314Ah) for energy storage. These new-type lithium batteries offer higher charge/discharge efficiency and boast over 6000 cycles, providing a lifespan of over 10 years, significantly longer than lead-acid batteries. A built-in Battery Management System (BMS) protects the battery from overcharge, overdischarge, overheating, and short circuits.

Key Installation Steps (Summary):

1. Mount Solar Panels: Securely mount the solar panels in a location with optimal sun exposure, following manufacturer guidelines for racking and tilt angles.
2. Connect Solar Panels: Wire the solar panels in series and/or parallel configurations as required by the inverter's input specifications. Connect them to the inverter's PV input terminals.
3. Install Inverter: Mount the hybrid inverter in a cool, dry, and well-ventilated area, away from direct sunlight and flammable materials.
4. Connect Batteries: Connect the lithium battery pack to the inverter's battery terminals, ensuring correct polarity.
5. Connect to Load/Grid: Connect the inverter's AC output to your home's electrical panel or specific loads. If grid-tied, ensure proper grid connection and compliance with utility requirements.
6. Grounding: Ensure all components are properly grounded according to local electrical codes.
7. Initial Power-Up: Follow the inverter's specific power-up sequence, typically involving turning on battery breakers first, then PV input, and finally AC output.

6. Operating Instructions

Once installed, your Dawnice solar system will automatically generate power from the solar panels, convert it via the inverter, and either supply it to your loads or store it in the batteries. The 10kW system is capable of generating approximately 38.4kWh per day under 4 hours of full sunlight conditions, providing ample power for various AC 110V/240V devices.

6.1. Inverter Display and Monitoring

The hybrid inverter features a display panel that provides real-time information on system status, power generation, battery charge level, and error codes. Refer to the inverter's dedicated manual for detailed instructions on navigating the display and configuring settings. The battery pack also supports Bluetooth/WiFi/APP monitoring for convenient remote access to battery status.

6.2. System Operation Modes

Your hybrid inverter supports various operation modes, including:

• Self-Consumption Mode: Prioritizes using solar power for loads, then battery power, and finally grid power (if connected).
• Battery Priority Mode: Prioritizes using battery power, then solar, and finally grid.
• Grid-Tie with Backup: Utilizes solar and battery power, but can also feed excess power to the grid and draw from the grid when solar/battery power is insufficient.

Consult the inverter's manual for detailed instructions on selecting and configuring these modes.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your solar power system.

• Solar Panels: Periodically clean the surface of the solar panels to remove dust, dirt, and debris that can reduce efficiency. Use a soft brush and water. Inspect for any physical damage or loose connections.
• Inverter: Ensure the inverter's ventilation openings are clear and free from obstructions. Keep the area around the inverter clean and dry. Check for any unusual noises or smells.
• Batteries: While the lithium batteries are low-maintenance, regularly monitor their state of charge via the inverter display or app. Ensure the battery environment is within recommended temperature ranges. The batteries have a lifespan of over 10 years with more than 6000 cycles.
• Cables and Connections: Annually inspect all wiring and connections for signs of wear, corrosion, or loosening. Tighten any loose connections.
