Roaming Solar

by Adrian 24th Jan 2015 - equipment

We’re currently in the Caribbean roaming the seas in a very self sufficient manner. We are making our own water, generating our own electricity, shopping locally and living quite cheaply and well. (We’ll all be reading the Guardian , not washing and wearing dreads soon if we carry on like this!)

(not much chance of that)

Coachroof Solar PanelsOne little modification I made before leaving Las Palmas which is helping considerably was replacing the two 65W factory supplied solar panels built into either side of the coachroof with more efficient 100W mono-crystalline ones.

Autohelms and power decisions …

by Adrian 14th Aug 2014 - equipment

We’re currently at anchor in Sines and nearly around the bottom corner of Portugal.

Sines, Portugal

Next stop tomorrow is Lagos on the Algarve which is where we finish this leg of the journey south and I head back to the UK for a week before it’s back to do the next bit across to the Canaries. That’ll be fun as it’s quite different and very offshore!

Solar Current Meters

by Adrian 19th Jan 2014 - equipment

Once I’d fitted our new solar panels, it seemed obvious to want to know how much current they were producing individually.

Solar Charge Meters

I have fitted simple digital current meters across each of our 3 solar panel to accurately measure and show the current flowing into the battery from each charge controller.

(Interestingly, with full batteries and the main solar panels pumping current into the system, the two smaller charge controllers detect the full state and back off and don’t contribute anything – hence the near-zero input figures here.

Isolation Transformer

by Adrian 20th Feb 2013 - equipment

We’ve had a galvanitic isolator (protecting the boat’s hull against earth current leakage) installed since launch, but I’ve recently taken shorepower isolation and galvanitic protection to the next level.

Isolation TransformerI’ve had a custom isolation transformer made which like all things on the boat, performs multiple functions:

1) It physically isolates the boat’s 240V electrics from the shore power by the use of physically separate transformer coils which transfer electricity from one coil to another via electromagnetic induction.
