Share what has worked for NWE Ten years of flotillas to Alaska

This year Five boats to Prince William Sound

>100,000 miles of West Coast of Vancouver Island and Alaska travel

>250,000 cumulative miles traveled

>30,000 cruising hours

MORE THAN ONE WAY Many very knowledgeable owners in attendance

Welcome your input

We have clients who may spend two weeks on a boat

Systems◦ Simple◦ Reliable◦ Easy to use◦ Consistent between boats

Inverters What are they?

◦ Convert battery power to 110 volt outlet power◦ Can use house hold appliances when:

◦ Not plugged into shore power◦ Generator not running

◦ Battery Charger ◦ Often best charger on the boat◦ Usually can charge 120 AMPS in bulk charge mode◦ Average about 100 AMPS per hour in charge mode

Some Common Uses Power Toaster

Microwave

Ice Maker

Television & DVD player

Lights

Blender

Mixer

Hair dryer

Coffee Maker

Common OEM Installation Normal factory installation of alternators

◦ 70 – 100 AMPS◦ One engine charges start bank◦ One engine charges house bank◦ Cruise at 8 kts◦ Given engine RPM most alternators at cruise output about 50 AMPS◦ 25-35 AMPS to run boat◦ 15-25 AMPS left to charge batteries

House Battery Bank Four 200 AMP batteries = 400 AMPS

◦ At 12 volts, 50% discharged – fully charged at 112.6 volts◦ Need to put 200 AMPS back in batteries

Stuff to be aware of Batteries connected to inverter

◦ 12 volt battery fully charged at 12.6 volts◦ 50% discharged at 12.0 volts◦ Bad stuff happens when you go below 12.0 volts

◦ Cables can get hot◦ Switches can burn out◦ Battery life shorten◦ Lower voltages can ruin battery

How long does it take to charge my Batteries?

With alternators while cruising – 20 AMPS /hour = 10 hours.

With Generator – two hours

When remote panel on inverter says “float Charge”

Typical morning/evening on Deception
