Thanks Brian, i do appreciate the offer
, but i suspect the cost of postage to the UK would be prohibitive
.Talk of big heatsinks made me think of the case of the santerno inverter: i originally acquired two of them as donors for an inverter build (3.3kva toroidal transformers), but as long as the powerjack keeps going that project's low priority. Looks like a good home for the mppt, although i might have to grind off the top bit where the toroidal tx and inductor were mounted.
It's a big stainless box with a massive heatsink, with a 20x4 lcd already mounted on the front face (why didn't i think of it before?!)
The round grey thing is a 5mH inductor that was in series with the 180v primary of the transformer, so must have been rated for 18A. Might be worth un-potting and adapting it?
The ferrite Ecore inductor, wound with 11 turns 25mm2 blue wire is one i put together for the inverter build, but then read some more and realised it would saturate at ~40A or so IIRC (about 50uH as is), so it might be more suited to the mppt, but I'm not really ready to think about inductors yet - need to finish the mppt main board first. Only room in my head for one problem at a time
