Marine Wind Generator Installation
A marine wind generator keeps charging when the sun has gone down and the engine is off, which makes it a natural partner to solar on a boat that spends time on a mooring or at anchor. We handle the electrical side of fitting a boat wind turbine: the cable run from the mast or pole, the regulator, the dump load and how it all joins your battery bank.
Wind charging is simple in principle and easy to get wrong in practice. A turbine produces power in gusts, can overcharge a full bank if nothing controls it, and sends current down a long cable from the stern pole or mizzen. The installation has to cope with all three.
We work from Shoreham Airport and fit equipment aboard at your berth anywhere along the South Coast between Brighton and Southampton.
What a wind generator installation involves
The mechanical mounting of the pole or bracket is planned with you, and the electrical work then follows the turbine maker's instructions. Cable is sized for the length of the run so that voltage drop does not throw away the output you paid for. A suitable fuse or breaker protects the circuit close to the battery, and a stop switch lets you brake the turbine before a blow or when you leave the boat.
- Charge regulator matched to the turbine and battery chemistry
- Dump load or diversion so a full bank is never overcharged
- Correctly sized, tinned marine cable with sealed deck entry
- Overcurrent protection and an accessible stop or brake switch
Wind, solar and lithium working together
Most boats with a turbine also carry solar, and the two need to agree on what a full battery looks like. With a LiFePO4 bank the regulator settings matter even more, because lithium wants a defined charge voltage and no long float. We set every charging source to the same battery profile and, where Victron monitoring is fitted, you can see what the wind is putting in alongside solar yield and state of charge.

Choosing a wind generator for your boat
People often ask for the best marine wind generator, and the honest answer is that it depends on the boat. Things worth weighing are the typical wind where you sail or moor, how much noise and vibration you will accept in the cockpit, where a pole can be mounted safely clear of crew and rigging, and how much daily energy you actually use. A quick look at your loads and existing charging helps decide whether wind is worth adding at all, or whether more solar would do the job more quietly.
Before work starts
Tell us the boat, the turbine you have or are considering, and where you would like it. We look at the battery bank, the existing charging and the cable route, then give you a written quote that sets out the electrical scope. At handover we show you how to stop the turbine and what the regulator is telling you.
Frequently asked questions
What is the best marine wind generator?
There is no single best one. The right turbine depends on your typical wind, mounting position, tolerance for noise and how much power you use each day. We help you weigh those against your existing charging before you buy.
Do I need a regulator for a boat wind turbine?
Yes. A regulator with a dump load or diversion stops the turbine overcharging a full battery bank and lets you set the charge voltage to suit lead-acid or lithium.
Can a wind generator charge lithium batteries?
It can, provided the regulator is set for LiFePO4 and agrees with your other charging sources. We check that as part of the installation.
Do you mount the pole as well?
We plan the position with you and handle the electrical installation. Mounting arrangements depend on the boat and are agreed in the written quote.
