Norwesco 4-pole DC isolating switch

In some cases, it is necessary to equip your installation with a DC isolating switch. In the Netherlands, this is not mandatory and almost all inverters are already equipped with and DC switch themselves so it is often unnecessary.

There are some exceptions of course including the Growatt SPF Off Grid inverter. It does not have a DC switch, so it makes sense to install one separately. Also, in several countries it is mandatory to install an extra DC switch anyway.

The DC work switch Norwesco 4-pole is as the name says 4-pole so you can connect 2 strings to it to switch. And there are 5 variants for different powers of course!
