solar rct instalation

[Tokkiebod]

iam busy installing a rct 5kva solar system. I need a a dc tripswitch between the pv and the inverter. There are 4 300watt 24v panels. 2 in series in parrallel with the other 2 to give 48v volt. to the inverter.
What size dctripswitch do I need? do I also need one to the 4 200ah batterys and what size.

None of that sounds right.

300W panels will usually be 36V@8A, not 24V.

2 in series will be 72V @ 8A, in parallel, 72V @ 16A -> Inverter.

You'd likely want a 100V DC rated on/off switch (not a tripswitch).

However, I'd first want to check the values.
