Ok I have been away for work but today i managed a bit more progress,

the head now has a tail



I salvaged 3 large UPS units that i have started to dismantle for parts so i decided to start on the monitoring unit, this is designed to monitor the incomming voltage of 2 sources with the displays switchable, have individual windmill shutdown switches and a current monitor, I have just completed mounting the components for one of G Hurds dump load controllers and i think this will house a pair of those,   so with that in mind  here is the empty (before) enclosure i managed to salvage



Here is the front panel with the meters mounted and a test voltage of 9.7 volts going into a 50ohm load



and here is a quick look at the guts of the box,  i have yet to wire the windmill stop switches in  and the load  will be part of my dump load  but im using it here just to test the panel.  Everything here is all salvage aside from the meters which were off ebay    the big UPS's have a wealth of parts  including the nice dump loads



still alot of wiring to do and an enclosure for the dump loads   im focusing on building it in halfs at pres    also may swop out the bridge i have installed for a nice chunky 40A diode as the bridge on the input drops nearly a volt    

Just got notification that my Rotors and Arbors are in customs and will be with me next week,  bought about 30 foot of 4 core tri rated cable about 8mm section per pair    from a local scrap yard   and whilst there i bought an ally A-con blower unit that looks perfect to turn into a micro hydro wheel      photos of that next time!

I bought one of those meters off ebay too but I find it jumps around quite a bit (Volts reading wanders by up to 1volt). Can you give more info on them and how you find them.

Cheers
