Use all of the solar energy to power the DAY&NIGHT vent and a built-in NiMh battery at the same time. The battery then ensures that the fan can operate for up to 24 hours either at night or without sunlight. In addition, a small bright LED in the middle of the underside of the fan can be used as light for orientation.  Product details

Expensive but very good The fan makes a very stable impression. Compared to the other solar fans available on the market, it is certainly the top model; but also correspondingly expensive. The fan comes on the foredeck. I will therefore create a neoprene ring that closes the air inlet because absolute waterproofness is not to be expected when a wave goes over it.

Product details


Use all of the solar energy to power the DAY&NIGHT vent and a built-in NiMh battery at the same time. The battery then ensures that the fan can operate for up to 24 hours either at night or without sunlight at a flow rate of 28 m³/hour (1000 ft³/h). In addition, a small, bright LED in the centre of the underside of the fan can be used as a light for orientation. Two slide switches on the underside of the fan control the inward ventilation/off/outward ventilation and orientation light (LED) on/off functions. When both switches are off, all solar power is used to charge the battery. The fan can be opened or closed via a robust sliding system. An integrated insect screen keeps uninvited guests away and can be unlocked and removed for cleaning with a simple twist.
The exterior is made of stainless steel. Easy assembly: After making the assembly hole, bed the exterior threaded trim plate and screw into the deck. Turn the interior threaded trim plate into place until flush with ceiling surface. Drill and fasten with screws if desired.
Please refer to the attached documents for all required dimensions.


Included
  • Fan unit with 15 solar cells
  • Pre-installed, rechargeable NiMh battery, 4.8 V, 2500 mAh
  • Removable insect screen
  • 2x outside / inside mounting frames
  • 2x seals for outdoor installation of frame and vent base
  • 6x VA Phillips countersunk screws 4.2x19 mm
  • Installation instructions (English)

Note

Rechargeable battery
The fan is equipped with a replaceable NiMh battery.
The solar cell keeps the battery charged during the day, so that the fan can run at night and in low light conditions.
Runtime with full battery and without sunlight up to 24 hours.
Average battery life depending on climatic operating conditions 3-5 years.
To maximize battery life, make sure that the battery is fully charged before using it for the first time.
To do this, expose the fan to full sunlight for at least 24 to 36 hours.
Please note that the charging time may vary due to external influences such as angle of light, weather conditions, shading of the solar cell, etc.

Switches
Two slide switches on the fan base control the functions.The three-stage switch controls the fan operation:
  • IN (= inward ventilation), CHG (= motor off, battery charging via solar on) and OUT (= outward ventilation)
  • The ON / OFF switch turns the LED orientation light on/off.
If both switches are set to "Off", all power generated by the solar panel will be used to charge the battery.

Oleg T.
by Oleg T. Flag of Croatia 1/8/2025 Verified purchase Variant: 24538
Under expectations
I installed the fan on the forward cabin hatch. The problem is that the large gasket supplied is to tin and you can't compress it when you screw the fan down. I remove the large gasket completely and the water is not entering the boat, which is good. A thicker (double thickness) gasket would be much better.
Also, the supplied battery is weak, the fan is working only when the sun is shining, it stops during night and on cloudy days. I expected it to work day and night. The air it moves when it runs is not much, hardly you can notice any air movement. I expected more from the fan.

Ineffective ventilation....
I ordered a Marenco D & N3 solar fan. After installation, it is clear that this system does not work. The humidity level is 90% when you wake up every morning. Really disappointed given the high price of this product

fan much too loud
I got the fan on February 20th. Bought. During a test run, the part seemed very loud to me and I claimed it. After 2 weeks I got a fan back. Probably the same part. The fan was very loud again. I then installed the part in the boat. Result Only to be used when you are not on board! You can even hear the unpleasant running noise from the neighboring boat in the harbor. The only positive workmanship and quality (except fan itself) is good
Magnus S.
by Magnus S. Flag of Sweden 6/27/2019 Variant: 24538
Useless
Bought the older version which had a disturbing sound just from the beginning. After a year the motor died and I contacted SVB who asked me to send back the unit. As it was mounted on the boat in Greece that wasn't possible but after I hade contact the manufactor directly instead they sent me a new on (newer model) without an fuzz, which was highly apreciated and really good customer care! Unfortunatly even this unit had that very annoying bearing noice and, even worse, I really couldn't notice any ventilation at all. In the end it was replaced by a passive cowl from Air-only (really recommendable and I suggest SVB to consider to offer them). Now the ventilation works (as long there is some wind) and without any noice.

Conclusion Keep it simple!

Is this appropriate for replacing the existing vent in a Bavaria 36 - 2004?
