Inverters & conversion
Controlling energy conversion, quality and availability.
WOLDIUS ENERGY supports the sizing, integration, commissioning and monitoring of inverters and conversion equipment for photovoltaic plants, hybrid systems, industrial installations and critical infrastructure.
System approach
The inverter is at the heart of energy conversion and control.
Selecting an inverter is not simply a matter of power rating. It must be consistent with the DC/AC architecture, string voltages and currents, MPPT ranges, potential energy storage, grid constraints, power quality, protection systems, communications and the site's availability objectives.
Final sizing is determined after analysing the energy profile, connected equipment, available grid and actual operating conditions of the site.
Technologies
Selecting the right conversion architecture for the project.
Central inverters
High-power solutions designed for utility-scale photovoltaic plants and large-capacity energy infrastructure.
Hybrid inverters
Combined conversion and control of photovoltaic generation, energy storage and, depending on the architecture, other energy sources.
PCS & bidirectional conversion
Conversion equipment dedicated to energy storage, microgrids and architectures requiring bidirectional energy flows.
