Wind Power

Wind power keeps batteries charging around the clock, which makes it a natural partner for solar on cruising boats and off-grid sites. This section brings together our wind power equipment: wind turbines from Rutland, Ryse Energy (AIR), Silentwind and Bornay; turbine accessories and stop switches; masts, towers and mounting hardware; wind and solar hybrid kits; and Watt&Sea hydrogenerators, which produce power from boat speed while sailing.

How to plan a wind power system

• Wind resource: average wind at your anchorage or site decides real output.
• Turbine size: match rated power and voltage to your battery bank and loads.
• Mounting: a solid, tall mount in clean air matters as much as the turbine.
• Control: plan the controller, stop switch and protection.

Wind turbine or hydrogenerator?

Turbines work at anchor and underway; hydrogenerators shine on long passages. See hydrogenerators.
