Installation Instructions

Before Installation

1. Check whether the solar controller’s ID is 1; if not, set it to 1.
2. Check whether the ID of the inverter is 3; if not, please set it to 3.
3. Wall installation or surface mounting installation is optional.

Wall Installation

• Step 1: Locate and drill screw holes based on the frame mounting dimension (175x50mm), and erect the plastic expansion bolts.
• Step 2: Use four M5 self-tapping screws to fix the frame.
• Step 3: Remove the decorative shell.
• Step 4: Use two M4 pan head screws to mount the MT75 surface on the base.
• Step 5: Install the decorative shell.

Surface Mounting Installation

• Step 1: Locate based on the installation size (176mm) and drill screw holes (no smaller than 158.2×85.2mm).
• Step 2: Remove the decorative shell.
• Step 3: Use two M4 pan head screws to fix MT75.
• Step 4: Install the decorative shell.

LCD Display Interface

1. The “Total PV generated power” and “Total DC load usage” is the solar controller’s parameter, which can be directly read and displayed by the MT75.
2. The “Total AC load usage” is calculated based on the inverter’s AC load power and displayed on the MT75.

Error Codes

Solar Controller Error Codes

Note: When the battery voltage is equal to the low voltage disconnect voltage (LVD) point of the controller, the controller and inverter’s output will be turned off.

Recommended Applications

Standard Application

1. Advantages
   MT75 monitors the solar controller and inverter’s operational status while controlling the AC load and DC load output by the Load ON/OFF button directly.

2. Connection Diagram

Operations

1. Connect the RS485 ports of MT75 to the controller and inverter.
2. Set MT75’s dry contact enable switch to OFF state.
3. Must set inverter switch to ON state.
4. MT75 load ON/OFF button directly controls the AC and DC load output.

Upgrade Application

Advantages
MT75 monitors the operational status and error codes of the solar controller and inverter at the same time. The Load ON/OFF button controls the inverter start or stop, effectively reducing the inverter’s loss and extending the system’s lifetime.
