Thank you guys, I’m happy about the helpful resonances, I’m sure other people will also get back here when designing their solar-powered gateways. @wolfp thank you for the fuse hint!
@CRIJapan that’s a nice setup, I’ve also got two of those charge controllers that are very cheap and can also be used for AGM batteries. The size of the solar panel and the 10Ah look a bit underdimensioned to me but in sunny regions it might be fine and for many applications you don’t need to have 24/7 lora coverage.
