Below is a sample diagram of the AC module system.
AC Module
PV Rack
1. AC module
- Consists of a DC module and a micro inverter.
- Performs power conversion from solar power to AC power and maximizes power generation
by performing MPPT (Maximum Power Point Tracking).
2. EnerBox2 (Communication Gateway)
- Collects data from the installed AC module system via AC cable.
- Uses wireless connection to transmit data to a server.
3. Monitoring App
- Monitors how much power is produced by the AC module system.
- Transmits the condition of the system to the service center in case of a problem.
• PV rack: Structure used to attach AC modules on surfaces like roofs, empty plots etc
• AC junction box: Container for electrical connections of AC wiring.
• Distribution panel : Component of an electricity supply system which divides an electrical power feed into
