Hey there, fellow solar enthusiast and maker! I got something simple yet super handy to share with you – the Betteri replacement pins. If you've dabbled in microinverter-based systems like the Hoymiles HM series or even embarked on your own mini "Balcony power station /Balkonkraftwerk" adventure, these pins are here to make your life a bit sunnier.

What's the purpose of Microinverters? Microinverters are like the wizards behind the scenes of your small-scale solar power setup. You know those snazzy solar panels soaking up sunlight on your balcony or rooftop? Well, microinverters take the direct current (DC) they produce and work their magic, transforming it into good ol' alternating current (AC) electricity that powers your gadgets and gizmos.

See one of my projects, the solartable, that is utilizing an HM400: https://github.com/Dom1n1c/Solartable

Whether you're into the whole "Balkonkraftwerk" trend – where you turn your balcony into a mini power station – or you've got a neat microinverter-based setup going, these little powerhouses make energy conversion smarter and more efficient.

So, why do you need those replacement pins? Picture this: you're all about that microinverter life, but sometimes those tiny connectors that keep everything humming along start acting up. That's where the Betteri Replacement Pins come to the rescue. These are like the unsung heroes of your microinverter system – unassuming yet essential.
At the time of writing there are no spare parts available from the manufacturer.

Printing:
I recommend a solid material such as:
PETG, ABS or ASA (ASA is preferred), print it in a high resolution and use support if needed. There is a version without support available.
