Yes... I'll have to do a bit more digging. I might just go with a 2/0 AWG (70mm sq), if the only downside is that it costs a bit more? Or perhaps I can do as you suggested and have a 175A fuse for the inverter and see how that goes, and keep a 300A fuse for the battery protection. Oops, thanks...

Ahh thank you for sharing what you picked up!! Re the 24v-12v converter, yes! I was thinking in 12v.. Thank you for the advice on having an inverter disconnect switch, will have to incorporate that. For the battery shunt, I was thinking 50mm sq. cable? Ahhh yes, the panels have Voc = 37...

Hey all, I'm after some fresh and more experienced eyes to double check for any design flaws before I spend some money! This is my first solar design for an off grid cabin. Appreciate any feedback! :)

Hey there everyone, I'm in the process of designing my first solar system to power an off grid cabin. I think I have everything organised, apart from grounding, which I'm getting stuck on. Does anyone have any advice of where to attach my system to the ground? My understanding is that the...

Thanks all for the advice. I've actually decided to go with 4S2P to start off with and see how things go with that - seems it will end up being simpler and cheaper, and I can always rewire if the shade is impacting too much. Some good takeaways from this post though. For reference I was...

Thank you both. The MC4 connectors I am planning on getting are rated at 39A, so in this case it should be okay?

Hey there people, I am currently designing my first solar system for an off grid cabin, with 2s4p due to shading (each panel 230W, Voc 37V, Vmp 30.3V, Isc 8.2A, Imp 7.6A, Max fuse rating 15A). I was originally planning on connecting each string to MC4 15A inline fuses, and then using three...
