I recently purchased a sailboat which the seller had removed the diesel engine and purchased an electric motor. It isn't installed as of yet. I called the manufacturer of the motor to learn more about it. It came with everything to hook it up. They said it could be wired ro 48v-96v battery bank. They recommended 72v. My question is do I need to separate battery banks? One for the motor and one for the house (12v or 24v not sure yet), or is there a way to separate the loads and downgrade voltage for the house side. I'm not going to use the motor unless necessary as it is a sailboat. I did purchase 10kw genset as a backup power source. Ideally want to run on solar but extended motoring could drain the batteries. Please help me figure this out. Thank you.
