New Generation Electrical System Spec

I am building a 56 foot cruising ketch and have a blank sheet in regard to the electrical system. I plan on having 800-1000 watts of solar panels, a wind generator, a 5-7KW diesel generator, a 100 amp main engine alternator and shore power.

The battery banks are a pair of 27 series for starting/bowthruster/windlass and 2-3 T105 house banks.

The challenge is in charging and inverters. There are many new options and products. Would be nice to have a controller/charger that manages all inputs including solar and wind as well as accomplishing the monitoring of system status. I assume that some of the new chargers can do this. Have also looked at charger/inverters.

Is there any system level "school solution" that is available for cruising boats?

Re: New Generation Electrical System Spec

I do not know of any charger that will accomplish what you wish - I doubt there are any. With one device controlling everything you desire any failure would shut everything down. Best with separate controllers for solar and wind. A separate battery bank monitor will keep you informed of battery bank status.

Why multiple house banks? A single larger bank is not only more efficient but the batteries will last longer with the shallower discharge a larger bank offers.

Victron Energy's VE.Net and "BluePower" solutions might come close to what you want - it isn't a 'single box', but an inverter/charger with different options/modules added depending on the power sources, batteries and loads you need.

.. but you'd have to talk to an experienced sales guy to work out exactly what's right for you.
