энергобаланс то есть владелец катера перед подключением какого-то дополнительного электроприбора должен ознакомиться с данными по токопотреблению,нагрузкам,и т.д.)чтобы избежать отрицательного энергобаланса катера

boat owners should first check what the power budget is so that Power consumption doesn't exceed the power budget. to obtain this information they have to refer to the authorized ХХХ dealers.
current audit = energy audit ( a list of all electrical loads)
power budget spreadsheet,power specifications

Electrical Load Calculation Process:
By Chuck Berrington
Vessel RelationShip
Size IP40
Excel 2000 Data File: Ip40Elec.xls 19K filesize
Directions to download: Click on link, save file to your computer, then open with Excel.

This Excel Work sheet is a guide for determining electrical loads for any yacht. This example is the worksheet I used to size the battery bank for our IP40, RelationShip.

What we are trying to determine is the number of amp-hours consumed in a 24 hour period for all the equipment that will be operating on the boat. Thank goodness it does not all operate at the same time. Also different equipment is operating at (1) anchor and (2) when sailing. Also, more energy is consumed when sailing at night -- so that is the worse case.
Therefore in summary, I have a total capacity of 980 amp-hours available
