Solar panel
Sirocco now has a 65Watt BP solar panel installed to the cross braces of the davits to run in conjunction with the wind generator. An SBC-7021 solar controller has been fitted to regulate things before going to the battery bank. Interestingly the solar controller has a facility to connect a night light or anchor light to that will come on when panel voltage drops to 3.5V and extinguishes when it reaches 3.5V (night time) it will self adjust as the seasons change, it will also display the panel voltage input for the last 3 days, neat piece of kit.
I bought a NASA BM-1 battery monitor recently and fitted it. This will constantly monitor all input and discharge voltage of the battery bank so we know exactly at what state of charge they are at and how long to go till we run them flat! It is very handy for working out a daily electrical load sheet, as it is capable of showing the amps of every item that is turned on, even one cabin halogen bulb! In an effort to quieten things down, I removed the blades from the wind generator and cleaned them up by removing all the small moulding plastic that was attached to them. The leading and trailing edges were shaped accordingly and 2 coats of marine varnish applied to fill minor blemishes on the surface. In the lighter winds we are now experiencing they do sound quieter, the summer sea breezes will be the true test of any improvement.
The next project is to install and commission the Raymarine S1G Type 1 linear drive ST6002 autopilot system we have just bought, this will be a challenging piece of kit to install, especially the actuator, but once this is done Sirocco will become a real Cruiser.
Till next time, fair winds, Mike.
