MOES Smart Automatic Transfer Switch

1. Introduction

This manual provides comprehensive instructions for the installation, operation, and maintenance of your MOES BAT-80A Smart Automatic Transfer Switch. This device is designed to manage power flow between DC input sources (inverter) and AC input sources (public power/grid) in off-grid solar and wind systems, ensuring continuous power supply and optimizing energy usage.

2. Safety Information

• Installation must be performed by qualified personnel in accordance with local electrical codes.
• Ensure all power sources are disconnected before installation or maintenance to prevent electric shock.
• Verify correct wiring polarity for battery connections.
• Do not operate the device if it appears damaged.
• The device is designed for specific voltage and current ratings (80A, 8KW/100-120V, 16KW/220-240V). Exceeding these limits can cause damage or hazards.
• This device includes surge protection; however, additional external surge protection may be required depending on your system.

3. Product Overview

3.1 Key Features

• Automatic power switching between inverter (DC input) and public power (AC input).
• Supports off-grid solar and wind systems.
• Manual source switching capability.
• Integrated Battery Management System (BMS) for monitoring grid, battery, and inverter voltage, current, power, and electricity consumption.
• Fast switching times: Inverter to public power ≤10ms, public power to inverter ≤16ms.
• Surge protection for enhanced circuit safety.
• Large LCD display for real-time status monitoring.
• Auto-distinguishes DC 12/24/48V and AC 100-120V 60HZ / 220-240V 50HZ.
• Adjustable battery low voltage transfer (cut-off) and recovery set-points.
• MOES App Bluetooth control (requires MOES Bluetooth hub for remote control outside Bluetooth range).

5. Setup and Installation

Proper installation is crucial for the safe and efficient operation of your automatic transfer switch. Please follow these steps carefully.

5.1 Wiring Diagram

Refer to the wiring diagram below for connecting the public power, inverter, battery, and load to the transfer switch.

Figure 3: Product Wiring Diagram. This diagram illustrates the connections for a typical off-grid system, showing the solar panel, wind generator, solar charge controller, battery, inverter, MOES transfer switch, grid connection, and household load.

Important: Ensure that the neutral (N) and live (L) lines are correctly identified and connected for all AC inputs and outputs. The battery terminals are clearly marked positive (+) and negative (-).

6. Operating Instructions

The MOES BAT-80A offers both automatic and manual operation modes, along with smart control via the MOES App.

6.1 Automatic Switching Logic

• Inverter Priority: The system prioritizes power from the inverter (derived from solar/wind energy).
• Automatic Transfer to Grid: If the battery voltage drops below the user-defined "cut-off" point (e.g., due to insufficient solar/wind energy), the switch will automatically transfer the load to public power (grid) to protect the battery.
• Automatic Transfer to Inverter: When the battery voltage recovers and rises above the user-defined "recovery" point, the switch will automatically transfer the load back to the inverter.

Figure 4: Product Function Diagram. This diagram illustrates the automatic power switching logic between grid power and battery/inverter power based on battery charge levels.

Figure 5: Fast Switching Speed. This image highlights the rapid transfer times (≤10ms from inverter to public power, ≤16ms from public power to inverter) ensuring uninterrupted operation of connected devices.

6.2 Manual Switching

The device supports manual switching between power sources. Consult the device's physical controls for manual override options.

6.3 MOES App Control

The MOES BAT-80A can be monitored and controlled via the MOES App. A Bluetooth hub (included) is required for remote control beyond Bluetooth range.

6.4 Adjustable Set-points

You can customize the battery low voltage transfer (cut-off) and recovery voltage set-points directly on the device or via the MOES App. Ensure the recovery voltage is always set higher than the cut-off voltage. These settings are compatible with various battery types including Sealed, Gel, Lead-acid, and Lithium batteries, provided the voltage is within the device's operating range.

7. Maintenance

• Regularly inspect all wiring connections for tightness and signs of wear or corrosion.
• Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning.
• Periodically check the LCD display for any error messages or unusual readings.
• Ensure adequate ventilation around the device to prevent overheating.
