I am working on a CD I plan to sell that will cover several sizes and types from 100 watts to around 10 to 15 kw. And the build for each of them is going to be based on how to do it with simple ,cheaper and often salvage or surplus components.
I will have lists of everything both in new costs and what I have been able to find used.
I am strongly leaning towards simple, reliable and cost effective DIY designs. The total cost outlay for each build will only depend on your scrounging and recycling skills.
well unless for large setups that practically invalidates this discussion, it will probalby be more expsensive to get a 250 W GTI validated than buying one.Yes in the UK it must be approved i.e. G83 certified.
I have checked with my supplier Atlantic Electric (Scottish div) and they will supply and fit an export meter free of charge as long as the GTI is G83approved.
