What are these din breakers and fuses for?

[lerryn.hawken]

Hey team I just got my 1st kit, a growatt spf3000 24v, 4 solar panels, 4 6v battery's and this assortment of dins.. I have a pretty good idea what they are for but the 1 with the single pe on the bottom and the dc+/- dc-/+ on the top has me wondering..
Help!

The fuses, low current circuit breaker and surge arrestor would be for the solar panels. The high current breaker for the battery to inverter connection.

Welcome to the forum.

Surge protection device for the PV wiring from panel array to inverter.

Thanks for that but I still don't know how the wireing works with the 2 positive and negative on the top and the single pe at the bottom??

Like this. The bottom is where the power gets dumped if bad things happen

I never took one until things were covered up, I've since upgraded inverters too. The attached should explain it.

Edit to add the obvious, go to G in the panel not the N where my hand drawn line lands.
