Follow the electrons

Remember we had the big storms in January ( see Yes dear we do have storms in Holland) .  Right around that time the Venus warned me that the shore power was AWOL.  Well no Biggy was my reaction, the batteries are full , 800 AH 24V batteries ( yes Mastervolt, because I could get them really really cheap.) . so that is 25.44 * 800 = 20.35 KWH.  That would keep the bilge pump and Venus going long enough.

So mid March a friend goes to Jan-Kees,  they had a terrible flight, well they did book United!  Had no luggage and then NO 220V.   So some frantic texting ,  I suggested to look to the shore power , shore breaker, shore cable, breakers.   Well after a lot of work , they found out it was only the 220V primary outlet breaker who kept tripping.  Unfortunately, the shore breaker flips just before the panel breaker, so the harbor master was called a few times.   All what had to be done, was, uncouple shore power and test it while on inverting.  they exchanged breakers on the panel, but the problem persisted.   Perhaps some condensation water.  They gave up, did not wanted to listen to advise, because they knew how it all worked, and stayed on Jan-Kees without 220V for a month.

Then 3 weeks a Dutch friend goes to Jan-Kees, to do some cycling in the area.  Marius was in the same research department as me in the 1980’s so I knew he would find the problem.  We discussed it could be the Fridge or the outside light or outside motion light.   When I got a notification of the Victron Venus that there was no shore power, I knew Marius was testing.  the first thing he did was turn the outside motion light off, and VOILA…..Electrons were coming out of outlets. the Fridge got a shiver, and got cold.   Marius went outside and inspected the light and yes during the storm it must have shorted.  That is what you get with a cheap Chinese Led Motion sensor light in the mast.
