Prior to the Ashlett regatta and the Drascamp event I have jury rigged the installation of a Photonic Universe solar panel and its controller.
It should provide intelligent charging and allow me to run the cool box/ fridge for extended periods.
Drascamp will provide the test, although, having left the jury rig running for the past week, I will check the batteries on Thursday. I have been waiting for some specialist connectors that will allow me to remove the panel, leaving the wiring in place, but ensuring the shortest run of loose cable .
They have now arrived so if, as I hope, the batteries are showing full charge, I will route the cables and mount the Controller as a permanent fixture.
I will add some pictures and some more details about how well it works after a period of testing.
