Independant power sources.

G'day all

Reading a couple of threads here got me thinking as to what people use as a backup to their main power source. What sort of charging systems do you have for things like gps/laptop if your main power source is down. I am particularly interested in simple systems for out of the way place where batteries may not be readily available.
cheers.

Re: Independant power sources.

if one is in an out of the way place with allegedly normal stuff, solar works well, and laptop isnt gonna be a concern, as signals will not exist. yeah, there are places like that still.....

Re: Independant power sources.

Depends on how you describe "main power source" - inverter? house batteries? charging source?

We have an AC generator. If that goes, we have a large main inverter.

If our main inverter goes, we have a couple of smaller backup inverters than can be used. We also have a number of DC-DC converters that can run and charge computers, GPS, etc.

If our house batteries go, we have the two start batteries that can be used. If they go, there is a small battery in the dinghy…

We have several charging sources - solar, two alternators, the main charger, a backup charger and a portable charger.

If absolutely everything goes, we plan on bartering water (big watermaker) for use of someone's portable Honda genset.

Absolutely everything going is pretty much an extremely low probability - an event that causes it would probably require abandoning ship as it went down.
