WhisperPower, the SEIMI asset for on-board energy management

The partnership between WhisperPower and SEIMI is part of a desire for the French marine equipment distributor to become a major player in electric propulsion, while offering yachtsmen, regatta sailors and professionals, a package and a global solution around energy management on board a boat

A true reference in the development and manufacture of independent power supply systems, WhisperPower continues its international development by appointing SEIMI as the exclusive distributor of its products for France. A strong foothold in the French recreational and commercial marine markets and recognised know-how, two reasons that led the Dutch firm to opt for this choice.

As for the SEIMI, by relying on a wide range of quality products and WhisperPower's historic expertise, it has a real trump card to offer a range of products adapted to the needs of the yachtsman in terms of onboard energy management and to guarantee incomparable comfort at anchor and during navigation. From powering a light bulb in the saloon to powering an electric propulsion system, there is a custom solution for every need!

The WhisperPower offer includes generators, hybrid generators, solar panels, battery chargers, alternators and all kinds of lithium batteries/DC generator sets for electric propulsion systems.

A complete customised on-board energy management system!

Following a precise study of the user's expectations, SEIMI helps him to define the best complete energy production and management system for his vessel, so that he can take full advantage of its comfort equipment (stove, refrigerator, watermaker, water unit...), its electronic devices (laptop, VHF, radar, automatic pilot...), its interior and exterior lighting, but also an optimal management of the energy produced.

After quickly identifying the most suitable package, the SEIMI team will then modulate this on-board system according to the type of navigation, the type of boat (pleasure and commercial marine), the electrical equipment on board the ship and its energy consumption.

Pack 1: "Essential" On-Board Energy Pack

For boaters who want maximum comfort on board and want to reduce the running time of the diesel engine to a minimum, the Essential package, consisting of a complete system for a plug-and-play installation, is perfectly suited.

This "Green" electrical system has two main sources of electricity production. One or more WhisperSolar modules charge the batteries via the SunTrack duo solar charge controller, based on MPPT technology, while the second source is a 12-volt alternator mounted on the main engine and the connected starter battery. The link of this battery to the SunTrack Duo, allows a 3-step battery charge for the service battery. The new Supreme Combi 12 / 3000-100 is at the heart of the system, providing shore-to-ship charging and conversion of the service battery power to AC.

Pack 2: Energy Pack on board "Comfort"

This on-board system offers all the comfort of a home while sailing, at anchor and in marinas. The battery is charged by the main engine or by the Piccolo 5, the 4.4 kVA emergency generator, which can be set to an automatic start/stop system as standard. The solar panels provide a basic energy flow. The WPC inverter/charger is equipped with a plug-and-play connection for shore power and a generator. The inverter, available in 2, 3 and 5 kVA output power, supplies 230 V (or 117 V) quietly and continuously. The Piccolo starts automatically when a battery recharge is required.

Pack 3: On-board energy pack "PRO / Admiral DC"

With the advanced Admiral (DC) system, an almost unlimited use of 230 V on board, without a generator in operation, or even without the main engine running, is guaranteed. Electric cooking, washing, drying, use of air conditioning and even roll stabilization during navigation. With this system, the roles are reversed: a high-capacity 7 or 14 kVA inverter supplies the 230 V 50 Hz appliances from the on-board battery. The much smaller generator, the Genverter, then provides energy when the battery needs to be recharged. Fast charging is achieved by the DC PowerCube, which quickly recharges the on-board battery. The DC generator technology results in a short and quiet generator run time.

Pack 4: On-board energy pack "Pack PRO / Admiral AC"

Almost similar to Pack 3, it is the Genverter WhisperPower 230V 117V of 8, 10, 12, 15, kVA or more, which is now the main power source on board with the Admiral AC on-board system. One, two or more Supreme Pro battery chargers of 80 or 100 A each, adaptable to any input power, take care of charging the batteries and providing DC power to on-board devices when shore power is available. The PowerCube AC sine wave inverter functions as a second, silent AC power source during generator shutdown periods. A perfect combination of high-efficiency, high-end generator and inverter technology. A wide choice of batteries, ranging from lithium-ion to 2-volt gel batteries, completes this package.
