3. Product Overview

The EARNMee ES3000BS-72 is a 3000W hybrid solar inverter charger designed for various power systems, including home backup, RV, and off-grid applications. It integrates a pure sine wave inverter, a 60A MPPT solar charge controller, and a battery charger into a single unit.

Key Features:

• High-Efficiency MPPT Technology: Maximizes solar power input with up to 99% tracking efficiency.
• Pure Sine Wave Output: Provides stable 110V/120V AC power suitable for sensitive electronics.
• Intelligent Dual-Screen Interactive System: Real-time display of inverter data, including voltage, current, power, and temperature.
• Comprehensive 6-in-1 Protection System: Includes protection against short circuit, low voltage, over-temperature, overload, over voltage, and pre-power overload.
• Universal Battery Compatibility: Supports lead-acid, colloidal, LiFePO4, and ternary lithium batteries with user-definable charging and discharging parameters.
• Automatic AC/PV Input Switching: Supports automatic switching between AC input and PV input during power outages (AC 120V input/output only).

4. Setup and Installation

Proper installation is critical for the safe and efficient operation of your inverter. Ensure the installation environment is dry, well-ventilated, and free from direct sunlight or heat sources.

4.1 Mounting

Mount the inverter on a vertical surface using appropriate mounting hardware. Ensure there is sufficient clearance around the unit for airflow, especially around the cooling fans.

4.2 Wiring Connections

All wiring should be performed by a qualified electrician. Use appropriately sized cables for all connections to prevent overheating and ensure optimal performance.

1. Battery Connection: Connect the battery bank to the DC input terminals (+ and -). Ensure correct polarity. The inverter supports 72V DC battery systems.
2. PV Panel Connection: Connect your solar panels to the PV input terminals. Ensure the maximum PV input voltage (230V) is not exceeded.
3. AC Input Connection: Connect the AC grid power (110V/120V AC) to the AC IN terminals.
4. AC Output Connection: Connect your AC loads (appliances) to the MAIN OUT terminals.

Important Note: This version of the inverter does not support AC charging. When the battery runs out, it supports switching to AC backup. The inverter supports AC120V input and output only. It does not support AC120V input to AC220V output, or AC220V input to AC120V output.

To protect the inverter when using AC input, the maximum AC input current should not exceed 120% of the normal input (rated power divided by AC120V). Exceeding this limit may damage the switcher or inverter.

5. Operating Instructions

Once all connections are secure, you can power on the inverter.

5.1 Initial Power-Up

1. Ensure all external switches (battery, PV, AC input) are in the OFF position.
2. Turn on the battery breaker/switch.
3. Turn on the PV array breaker/switch.
4. Turn on the AC input breaker/switch.
5. Press the power button on the inverter to turn it ON.

5.2 Display Interface

The dual-screen display provides real-time operational data. Use the navigation buttons below the screen to cycle through different display modes and settings.

• PV: Solar panel input status.
• CHARGE: Battery charging status.
• LOAD: Output load status.
• ALARM: Indicates system warnings or errors.
• Four-color indicator light: Provides quick status updates for solar panel, charging, DC load, and warnings.

5.3 Battery Settings

The inverter supports various battery types. Refer to the detailed settings menu on the display to configure charging and discharging parameters specific to your battery type (lead-acid, colloidal, LiFePO4, ternary lithium) for optimal performance and lifespan.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your EARNMee inverter.

• Cleaning: Periodically clean the exterior of the inverter, especially the cooling vents, to prevent dust buildup. Use a soft, dry cloth. Do not use liquid cleaners.
• Connections: Annually inspect all wiring connections for tightness and signs of corrosion.
• Environment: Ensure the installation environment remains within specified temperature and humidity ranges.

7. Troubleshooting

The inverter features a 6-in-1 protection system that will trigger alarms or shut down the unit under certain conditions. The display will show error codes (E1-E6) to indicate specific issues.

If the issue persists after attempting the suggested solutions, please contact EARNMee customer support for assistance.
