1. Hot Coffee in the Morning (Without Waking her up!) NE EXPLORATIONS PSGBOA 2014

2. 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

3. 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

4. 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

5. Some Common Uses Power Toaster Microwave Ice Maker Television & DVD player Lights Blender Mixer Hair dryer Coffee Maker

6. 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

7. 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

8. 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

9. 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”

10. Typical morning/evening on Deception

11. Some thoughts on what has worked for NWE Inverters ◦Magnum Disconnect Switch ◦Blue Seas Heavy Duty – biggest you can fit Center Fielder ◦Blue Seas Batteries ◦AGM North Star, XXXX, “half” 200 AMP batteries ◦Lead Acid, Golf Cart System Monitor ◦Blue Seas Balmar Regulators Alternators ◦125 AMPS – 225 AMPS

12. Tools & Electrical Stuff Onboard Clamp Meter Crimping tool Assortment connectors Diagonal cutters Good electrical tape (3M) Shrink tubing Fuses – spare wired to fuse Wire ties Stripping tool 3M sealant Battery corrosion spray Corrosion X Super Lube

13. Experience – Let those sleep who want to sleep Batteries with lots of capacity No generator running Cup of coffee early in the morning
