Installation and Startup

Master Module Installation

The master module includes:

• A photovoltaic module
• DC/AC conversion electronics
• Male/female single-phase AC connections to link multiple master modules and connect to the AC grid
• Male/female DC connectors (MC4) to connect slave modules

The DC connections of the slave modules are directly connected to the master module, eliminating the risk of high DC voltage. The master module is mounted on brackets suitable for the installation context.

Slave Module Installation

The slave module(s) are positioned next to the master and connected to it via the appropriate cables mounted on the master.

Phase 1 - Install the AC Junction Box

• Install an appropriate junction box in an accessible location near the photovoltaic system (usually at the end of the AC branches).
• Insert the AC network cable into the junction box using a strain relief fitting.
• Wire the AC connector: L - red; N - black; PE - yellow/green.
• Connect the circuit from the AC junction box to the utility interconnection point.

Phase 2 - Mount the Modules on the Fixing Brackets

After positioning and securing the most suitable fixing structures for the context, position and secure the modules to them.

Phase 3 - Prepare for Parallel Connection of Master Modules

In case of parallel connection, remove the plugs from the master modules, except the one sealing the AC line.

Phase 4 - Connect the Modules in Parallel

After positioning and securing the modules, connect the master modules in parallel using the appropriate male/female AC connectors.

Phase 5 - Connect the Master Module to the Slave Module(s)

Only after connecting the AC branches and securing the uncovered side with the cap, connect the MC4 connectors of the master to the slave modules.

System Startup Instructions

• Turn on the switch for each AC branch.
• Turn on the main network switch. The system will begin producing energy after a one-minute wait.
• The master module's LED will start flashing red. Then it will flash blue. The blue color indicates energy production. The faster it flashes, the higher the energy production.
• Configure the internal Wi-Fi module following the appropriate manual.
• The master module will start sending performance data via Wi-Fi every 5 minutes. This allows the user to monitor production data for each master module via a specific website or app.
