having some billet aluminium milled into bracket/busbar to mount the heatsink parallel with the board. this will allow me to connect the feed to the toroids direclty to the busbar and use thermal compound on the heatsink backface, which i know will make a significant difference in cooling alone, coupled with the change in angle of the heatsink with air being blown directly down onto them should keep them nice and cool.
also in process of stitching some thick seatbelt type material used for cargo straps in a loop around the toroids for mounting them, or rather hanging, from the ceiling as inspired by sunnypower46.
also c101 copper busbar ordered, thankfully got it at trade price through local fabricator. inch and qtr by qtr , 6 metres of.
i found this useful for bar sizing based on currenthttps://www.copper.org/applications/electrical/busbar/busbar_ampacities.html
and this useful for wire sizing.http://www.engineeringtoolbox.com/wire-gauges-d_419.html
i got a piece of id 37mm tube turned down on the outside to slide into a scaffold tube to mount the istabreeze 2kw wind turbine on.
besides that had a tinker with some of the voltage sensors and relay timers, all seems to be straight forward.
waiting on a couple of bits and pieces but i can start work on the sensing circuits and gen control stuff.
