I just found out I can buy a decent 400W solar panel in the local hardware store for around 90€ these days.

Are there people around with experience in off-grid solar? There is quite some supply in cheap MPTT charge controllers on the internet. And I can’t afford a 700€ power station. But I would be able to buy a few power tool batteries or one of the lead-acid batteries people put in their caravan. Are there projects building a power station myself? Is this even worth it?

Maybe someone alredy wrote a blog post with recommendations or findings and failures along the way. Or has something similar running at home?

(Thanks to the mods for steering me towards the correct community.)

    Listen to this guy, made a solar powered trailer/workshop and battery storage is the biggest limitation. If you get 3 days of bad weather the battery drains and you go offline. Or you spend tons of money over sizing the system and the batteries are wasted 95% time. Its a game of numbers and use cases.
