Inverters
Inverters, or Inverters, are devices that are the heart of the PV Installation. Their task is to convert direct current (DC), produced by PV modules, into alternating current (AC), which we use every day.
Inverters can be divided into 2 basic groups:
• Single-phase inverters up to 3.68kW
• Three-phase inverters above 4kW
The division concerns the number of connection phases.
If we have a choice between a single-phase inverter and a three-phase inverter, it is worth using three-phase one, due to the greater stability of the network, which translates into smaller voltage fluctuations and smaller cross-sections of the wires used.
Single-phase Inverters
Single-phase inverters are mainly used in small installations, mainly at home, where there is less power demand.
Detailed technical parameters are specified in the catalog cards available in the details of individual inverters.
Three-phase Inverters
Three-phase inverters have a much wider application for the installation of larger power demand.
Three-phase inverters are used for:
- larger domestic installations, where power consumption is a higher,
- industrial installations
- farms
- other facilities where we generally have much higher consumption, e.g. hotels, office buildings, guesthouses, resorts, etc.
Detailed technical parameters are specified in the catalog cards available in the details of individual inverters.
Micro Inverters
Microinverters are low-power single-phase inverters used to work with single photovoltaic modules.
Microinverters are used for micro-installations.
There are microinverters on the market that can be connected to 1 to 4 modules. Modules are connected directly to the inverter via MPPT connectors.
Detailed technical parameters are specified in the catalog cards available in the details of individual inverters.
