Our service

PEHN – our range of services

As an innovative and competent manufacturer of electric boats, we offer a wide range of technical services for everything to do with electric boats. In addition to drive and battery solutions, you can also get all other electro-technical services for your yacht or boat from us. In short: we take care of everything that should work on board with electricity. From the navigation lights to the bilge pump, from the underwater lights at the stern to the mooring lights at the bow. To ensure that this always works reliably, we work hand in hand with the selected suppliers and high quality components.

The right engine for your boat?

We always equip our electric boats with the same 2-3 engine variants that have proven themselves for this model. In the case of conversions or new installations, different solutions can be used due to the price or application, e.g. only with a more portable battery, extremely robust or very shallow draft here are some manufacturers we work with, but in addition to the motor, all components, ie controllers, batteries, Charger, instruments, etc. are matched to the boat by ours specialists.

Electric boat engine service

We do electric boat motor services for all common electric motors, mostly direct current motors but also good old series motors from Accumot to three-phase motors.

Anyone who comes to us with a combustion engine will receive a comprehensive service
HP Nautic for all brands (Mercury, Honda, Suzuki etc.)

Batteries and charging technology

As a certified service and system partner of various engine manufacturers and with years of experience with battery systems, we can install electric drives in boats and ships of all kinds.

For high-voltage projects, we have specialists on hand who will be happy to advise you individually.

We recommend lithium batteries for all electric motors from 1.6 kw DC.
The systems are configured from standard batteries, which, depending on the driving profile, size, weight and price, are seen as a complete system with a charger. Or we install special sizes depending on the boat and space situation and the required capacity, e.g. in modules of 5, 10, 20 kwh for mostly low-voltage, i.e. 48V systems up to 100 kwh.

We usually have large batteries > 250 Ah in stock – please contact us.

As a rule, we only install these in the commercial sector, where the battery acid level is regularly checked and topped up, otherwise the risk of malfunctions is too high.
For private customers, depending on the application, we recommend maintenance-free, explosion-proof so-called
Dry (AGM / gel) batteries

PV-Module

Flexible stick-on or detachable PV modules have become indispensable, especially on electric boats or sailing yachts.
We have been using Solbian modules for years and can customise your PV system to suit the needs of your boat. Whether it’s an ocean-going blue water yacht with a self-sufficient energy concept including a watermaker, a passenger ship or a self-sufficient electric boat that charges itself at a buoy on the lake and manages without a power socket all summer – we offer customised solutions.
Aesthetically adapted to the boat – as a walk-on non-slip surface, a cool mat or in an elegant wood look.

Installation of boat electric drives and conversion from combustion engines

We not only install your new electric motor and the battery and charging system, but we can also convert your existing petrol motor boat to an electric motor. You can discuss with our specialist how this could work and what it costs in individual cases.

We will be happy to prove to you that, calculated over a period of a few years, this is even cheaper with the same driving pleasure. We can offer you alternative electric boat drives from the most well-known manufacturers for all boats from 0.5 to 200 kW.

Whether outboard, flanged propulsion nacelle or inboard – we have the best system for your motorboat and your ship. Experience the new technological possibilities of electric mobility on the water. Combined with a fuel cell, solar technology or a gas-powered range extender, you get almost unlimited clean energy for your boat. We would be happy to provide you with a suitable conversion concept for your boat. Ask us about the possibilities.

With access to an extensive spare parts store, we can usually help immediately and if we don’t have the right component in stock, it will be obtained for you as quickly as possible.

Frequently asked questions

We have been building electric boats for almost 70 years. However, the question of range has only been asked more frequently in recent years. Our boats are designed so that they can be used during the day and recharged overnight. All boats have a battery capacity that is at least 2:1 in relation to the motor power. This means that they can be operated either at full throttle for 2 hours or at half speed for up to 6 hours. This results in a range of at least 40 km – which is more than sufficient for most of our local lakes.

Most electric boats can be charged using a conventional Schuko socket or a blue 3-pin CEE socket. These sockets are usually fused with 16A and could theoretically provide a charging capacity of up to 3.6 kW. However, charging sockets are often shared with other boats in the harbour. In addition, the shore connection on the boat is usually equipped with a 30mA residual current device (RCD) with a 13A FI/LS, which limits the charging power to approx. 2.8 kW. For this reason, we rarely install chargers with a power output of more than 1.5 kW so that two boats can easily share one socket.

For larger PEHN electric boats, we may install chargers with a power rating of up to 3 kW. In these cases, however, the boats must be connected to their own power supply. Special charging plugs such as type 2 or type 3, as used in electric cars, are not necessary in boat building. They would only incur considerable costs and require the conversion of all ports – without offering any real added value.
