OK this might not be the cheapest solution but it might be the smartest in the long term.
1. Xanterx make the kit you can trust. I have known them them controller inverter inverter and used their stuff for ages and it has NEVER failed me. I also have the 2500 with the Link 2000R controller. The 2500 is a work horse that has been proven for years. It is worth every single
penny mate, and you have a great charger as well a power tools and cold beers.
2. Yes separate your nav supply from your happy time stuff. If something goes wrong you want that computer to keep working no matter what. I even have a separate battery I can switch into that line should I need to isolate the entire main DC system for some reason.
3. Forget running long DC lines just run short DC lines and long AC ones to your kit. Makes for better engineering and saves a bomb on heavy DC cable.
this a very wise idea from Makai, "For the laptop
we had a dc-dc 12 volt to 19 volt inverter made. It has even a lower over head
as it plugs directly to the battery system. Huge losses occur when using the inverter to go from 12 to 110 and 110 to 19 volts (most computer charge rates). A good inverter losses 20 percent or more from 12 to 110 and then again from 110 to 19 volts." Mine is 15 volts DC but WTH anything that works and keeps working, right?
Now some everyday stuff you might want to think about. We are all over the place and spend most of our anchor
time away from marinas
. In fact there are usually no marinas
around the places we go. Running the gen set to pay an inverter to keep the beer
cold is a real, repeat REAL, costly pain in the back side! We have used house chest freezers for years on the inverter and they work fine its just that the overhead is massive. Think fuel
for the gen set mate plus spares, oil
, filters, all that stuff. Take a look at another thread on here about Sterling coleman coolers there are some great thoughts in there about efficient cooling
