Free power (Ithink)

I constructed a simple frame for the solar panel out of an old bed frame and a few other bits and pieces.  My mooring is south facing which makes for an easy installation.  The panel can be set at two different angles and can be folded flat too.

The cable enters the engine room via a bottle top filled with CT1.

So its all wired in but is it working?  I would guess so, but I am not really sure.  I bought a little ammeter but I must have wired it up wrong because when I plugged it in, the fuze blew. When I get home from work, the sun is low so there is nothing for my clamp meter to measure.  And if the batteries are nearly charged, they will not be accepting any great amperage anyway.  I will try and take a voltage reading at night with all the lights off but that is a bit hit and miss since the batteries should be rested without charge or discharge for at least an hour before testing.   I think the thing to do will be to test voltage and amperage at every opportunity over the next few weeks and try and build a picture from that.
