It’s mostly work and little fun here in paradise.<\/p>\n

The day my parents left I performed what I thought was a regular maintenance task. I checked the fluid levels in the house batteries and found them short of where I have been told the levels should be. So I diligently filled them with distilled water thinking a job well done.<\/p>\n

The following day I noticed the overall capacity of the batteries had plunged. Voltage in the mornings was very low compared to the Amp Hours used over night. I took a lot of advice from folks around here and on the internet. The two conclusions I was offered were either a) my batteries were hosed or b) they must have been heavily sulphated and the electrolyte quite weak before I filled them. (Lesson learned: take hydrometer readings before filling)<\/p>\n

so before shelling out another boat buck on batteries I decided to try and fix possible cause b). It took me a couple of days to properly learned how to exploit the resources I have at hand to address the problem. My daily cycle is now :
\n1) Wake up and turn on 72V\/12V cross charger with a view to have batteries mostly charged by 9:30
\n2) When skies permit, turn off 72V\/12V charger and use solar. Tell MPPT to equalize which will attempt to bring voltage to 16.3V
\n3) When we’re finished with what we’re doing, turn off house circuit (including fridges) to allow voltage to maximize. (All through this time watch the batteries to make sure fizzing\/electrolysis doesn’t spill over
\n4) Around 3pm turn on genset and continue equalizing house and charge drive bank (ready for morning cross charging)
\n5) Around 5pm revert to normal.<\/p>\n

Through all this I take regular hydrometer readings of a specific reference cell to see if we have continuing performance. So far the hydrometer reads have gone from f**k*d to just about ok and they keep on getting better. looks like I may have a few more days of this.<\/p>\n

Yesterday we bought the plane tickets for the kids to get from Antigua to St Martin. We sent a long communication to them to lay out all the detail including contingency communications. Because this is a separate ticket, delays to their first flights could mean they miss the final one. We can change the flight up to an hour before it’s due to take off. We will need to keep close tabs on their progress to know whether or not we’ll need to do this. Dec 24 will be fun.<\/p>\n

Tonight we’re going to be taught Mexican Train Dominoes or something like that. We’re having crew and friend of Bees Knees over as well as the crew and daughter of Godiva. We met Mike and his wife (I think) briefly last Wednesday at the cruisers get together.<\/p>\n
