The Technology of Berenik-E
The Berenik-E is a converted sailing catamaran measuring 11 metres in length, 6 metres in width and weighing around 5 tonnes.
The powerplant
|
14 PV-modules each 395 watt, 5.53 kW
 |
double-sided modules, more energy
|
2 modules form a string , 7 solar controller

There are no other power sources on board.
Cooking, refrigeration, and heating are all powered by electricity, and the dinghy also draws power for its electric outboard motor from the solar panels.
Experience has shown that the solar system’s output is more than sufficient during the summer months, even when covering long distances on a regular basis.
In august and september 2025, the distance covered was approximately 1,500 nautical miles.
AC power is supplied by a Victron Multiplus with 5,000 VA; this can also serve as a charger, though that has never been necessary.
The battery storage system
The energy is stored in two 16S LiFePO₄ batteries, each with a capacity of 280 Ah, providing a total of approximately 30 kWh of energy.
The drive system
Two 6 kW outboard motors from Epropulsion provide the propulsion.
