Nice. Glad to see my nanometer been used.
I got the parts to make more so when you need another one, just come past.
I'm also working on a high voltage nanometer. Still experimental. This is because actual domestic/commercial solar setups, that are grid connected, use high voltage solar setups. That is, they got like 10-20 panels in series, which can produce up to 400vdc at like 10amps.
Ive already started work on a high-power/high-voltage MPPT.
