Power Electronics
On-Grid - Cost-saving with the cleanest possible electricity
A good quality grid is available near the turbine installation & consumers. The turbine will
decrease your electricity bill considerably. The backbone is an induction generator that is
coupled to the grid and will provide over 90% uptime.
Basic Off-Grid - Reliable remote electricity, hydro only
A top quality micro-grid providing energy right from the water with the following features:
• Pure Sine Wave Inverter
• Controlled dump loads + Power Factor Correction (PFC) for optimal load balancing
• Starting battery for generator
Smart On/Off-Grid - Reliable electricity anywhere, combined hydro
A top quality micro-grid compatible with other power sources and energy storage. It has
the same functionalities of the basic off-grid solution, with the following additional
features:
• Peak consumer loads up to 3x turbine power, ensuring energy availability during peak demand
• Batteries dimensioned for peak-shaving and increased uptime till 99%
• Can be grid-connected with uninterrupted switching between on and off-grid.
• Easily integrates with other power sources like solar, wind, diesel, …
