How to Determine Power (force) Needed to Push a Boat

There has been a longstanding "rule of thumb" to determine the motor size for an electric repower: Take the existing diesel horsepower and divide by three.  Multiply that number by 750 to determine the (continuous) wattage rating for a motor. This inserts a lot of assuptions and ignores every relevant fact needed to determine the best solution.There are a lot of spreadsheets out there that will give an approximate answer.  I've seen them.  I've delved into their formulas.  I've found each and…See More

Belt size

As i stated in a post last winter I was having belt problems. the 1in L series timing belt was skipping teeth @ about 80-90 amps on my 48v system. I was having to much fun to change it over the summer. So I carried 2 spare belts all summer never needed them but better safe than sorry But have decided it was time to fix the problem so i ordered a set of cogs and a 1in h series belt. The end results are 18x15 3 blade with a 3:1 reduction and ME0913 motor @ full throttle now draws 150amps @ 49.6…See More

Battery monitoring and charge controller recommendations

GreetingsI have a 48V 300ah system for my ElectricYacht install. I am looking to provide both solar and wind generation to the system, solar first, then wind. I am looking at about a 200-300w Solar system due to current space limitations, and about 200w 48v wind.It appears that most 48v wind generators are self-regulating now - should I assume that I do not need a charge controller for both wind and solar?I am looking at each of the following charge controllers:…See More
