Microinverter System Operation
The grid-connected photovoltaic (PV) system with a microinverter consists of PV modules, the microinverter, a Wi-Fi router/repeater, a monitoring platform (web and app), and the electrical distribution grid. The microinverter converts DC power from PV modules into grid-compatible AC power.
Notice! Ensure a good Wi-Fi signal at the microinverter installation site for correct monitoring operation. If the signal is weak, install a Wi-Fi repeater or a wired router nearby.

Features
3.1. High Efficiency and Safety
- Efficiency: Each PV module input has an MPPT controller, ensuring maximum energy export to the grid regardless of other modules' performance. Shaded, dirty, or differently oriented modules do not affect others.
- Safety: The low DC voltage (tens of volts) eliminates the risk of fire from high-voltage DC arcs.
- Smarter Operation and Maintenance: Module-level operation and maintenance allow precise location and diagnosis of each PV module, simplifying operation and maintenance.
3.2. Flexibility
The microinverter converts DC power from PV modules into grid-compatible AC power. Compared to central and string inverters, it offers flexibility, high energy production, and low DC voltage safety, making it ideal for residential PV systems. Integrated Wi-Fi allows internet access via a home router, uploading operational data to the Intelbras Solar Plus platform (web and app) for monitoring.
3.3. Introduction to the Microinverter
Due to its high generation efficiency and excellent safety performance, the microinverter is widely used in residential PV systems. It has a single-phase AC output but can be connected to biphasic and triphasic grids. Verify voltage compatibility for your location.
Installation and Electrical Connections
4.1. Installation Environment Requirements
- Do not install in environments with flammable, combustible, or explosive products.
- Do not install in areas prone to water leakage.
- Do not install in locations with corrosive products (e.g., corrosive gases, organic solvents).
- The microinverter surface can be energized or reach high temperatures during operation. Do not touch it.
- Do not install in easily accessible locations.
- Good heat dissipation is crucial. Install in a ventilated environment.
- If installing in an enclosed space, use additional heat dissipation or ventilation devices. The ambient temperature should not exceed the outdoor ambient temperature.
- The average temperature within 1 meter around the microinverter is considered the operating temperature. Temperature and humidity must meet requirements: -40°C to +65°C, 0%-100% humidity.
- Consult Intelbras before installing outdoors in areas prone to salt damage (within 500 meters of the coast).
- Do not install in environments contaminated with chemicals like halogens and sulfides.
- Do not install in environments with vibration or strong electromagnetic fields (magnetic field intensity > 30 A/m).
- In dusty environments, ensure periodic cleaning of the equipment as dust accumulation can affect performance.
4.2. Installation Space Requirements
Ensure sufficient space around the microinverter's heatsink for heat dissipation. Minimum clearance of 20 mm is required on all sides.
Attention! Ensure the microinverter is at least 20 mm above the roof surface when installed on a roof, or 20 mm away from the wall surface when installed on a wall.
4.3. System Connection Diagram
The microinverter can be mounted directly below the PV module on the mounting structure. Low-voltage DC cables connect the PV module to the microinverter. Installation must comply with local technical regulations and standards.
- A dedicated breaker (single-phase or biphasic) or other load-break disconnect unit is required for each association of microinverters to ensure safe disconnection under load.
- Note: A Residual Current Device (RCD) should not be used to protect the AC circuit of the microinverter, as it may be damaged.
Attention!
- Perform all electrical installations according to local electrical standards.
- Only qualified personnel should install or replace the microinverter.
- Read all instructions and warnings in this manual, on the microinverter, and on the PV module before installation or use.
- Installation poses a risk of electric shock. Handle with care.
- Do not touch any energized parts of the system, including PV modules, while the system is connected to the grid.
Installation of surge protection devices is recommended according to local standards.

4.4. Microinverter Installation
Fixing the Microinverter
Always handle the microinverter by the mounting loop. Do not lift by the cables.
Recommended: Use mounting loop. Prohibited: Lift by cables.
Step 1: Detach one of the QR codes from the microinverter surface and affix it to the quick installation guide. This code will be used later for microinverter parameter configuration. Serial numbers should start with INMA.
Step 2: Adjust the mounting nuts on the rail as shown. The distance between the two nuts should be approximately 185 mm. Nuts and tools must be provided by the installer.
Step 3: Install the microinverter onto the rail using M8 screws with a torque of 9.0 Nm.
Attention!
- Do not install the microinverter on the edge of the support.
- It is recommended to install the microinverter mounting screws around the roof structure's mounting hook for better support and to prevent the mounting profile from bending under the microinverter's weight.
Connecting the AC Cable to the T-type Connector
Step 1: Remove the waterproof caps. Unscrew and remove the waterproof caps from the T-type connector.
Step 2: Open the T-type connector. Insert the disconnect tool into the bottom part of the connector and pull out the waterproof cap on the top.
Step 3: Pass the cable through the waterproof cap and sealing ring.
Step 4: Strip the protective and insulation layers to the specified length.
Step 5: Crimp the cold-pressed terminals onto the conductors using a crimping tool.
Step 6: Insert the L, N, and PE conductors into the corresponding holes in the connector.
Step 7: Tighten the terminal screws clockwise using a screwdriver (M4, 0.8 N.m).
Step 8: To assemble the connector, push the sealing ring and the waterproof cap into the connector compartment and tighten the waterproof cap.
Step 9: Attach the sealing plug. Use the sealing ring and plug if the second terminal of the T-type connector is not used.
Connection Steps
Step 1: Connect the external grounding cable using an M4 screw with a torque of 1.5 Nm.
Step 2: Connect the microinverter's DC connectors to the PV module connectors. Ensure correct polarity.
Attention!
- The PV1 DC connector must be connected to a PV module. Otherwise, the system may report a failure and not function correctly.
- When connecting DC connectors, ensure the order matches the actual PV module positions to facilitate future physical layout configuration in the monitoring platform.
- If not all DC connectors are used, seal unused connectors with IP67 waterproof plugs (installer-provided).
- If a PV module is too far from the microinverter, a DC extension cable will be needed (prepared by the installer).
- PV modules cannot be connected in series.
Step 3: After following the AC connection procedure described in "Connecting the AC Cable to the T-type Connector", verify the connection is secure.
Attention!
- Installation must comply with current technical standards for photovoltaic electrical installation (NBR 16690) and fire safety in photovoltaic installations.
