3 HOW IT WORKS

[Diagram: Schematic example of a Soladin in a PV plant, showing PV panels connected to the Soladin Web inverter, which outputs AC power to the Grid.]

3.1 PV-modules

Photovoltaic (PV) modules convert light into DC power. A series of modules is a string, connected to the inverter's DC input. The PV string operates at its optimum voltage (Maximum Power Point tracking) for maximum yield. A PV array is a plane of modules consisting of multiple strings.

3.2 Grid connected inverter

The Soladin Web is a grid-connected photovoltaic inverter that converts high-voltage DC power from PV panels into AC power, feeding it back into the public utility grid.

3.3 Isolated inverter

The Soladin Web is an isolated inverter featuring a High Frequency (HF) transformer for galvanic isolation between the DC (solar) and AC (grid) sides. It includes Isolation fault detection to monitor PV array isolation resistance.

3.4 Grid interface

The DC PV input is converted to a 230V AC output. The inverter is not suitable for stand-alone operation. The grid interface includes safety mechanisms: an output relay for grid isolation, DC injection monitoring, redundant grid voltage/frequency monitoring, and anti-islanding protection. Country settings are mandatory.

3.5 Communication

The Soladin Web communicates via Wi-Fi using devices like notebooks, smartphones, or tablets. For online monitoring, it connects via Wi-Fi through your internet router to the internet.
