Panel disconnect?

[AmyJones]

I'm looking for a way to disconnect the 1.64kw panels from the Victron 250/100. I've wired the panels in series (four 410w, 131v, and 10amp). What are my alternatives?

I would look for a 250V 30amp DC rated 2 pole disconnect switch. That way you can open both of the DC wires at the same time and since the switch is rated for DC it should be able to handle any arc produced.

I am presuming the Victron is rated for that high an input voltage.

what about a battery knife switch?

Just about any switch will work if it is rated for the DC voltage and amps it will see. Remember you really need to open the circuit for both wires so some type of 2 pole switch is required.

Thats so helpful...thankyou

You need a DC isolator switch. Google it. Normally all the strings would come into a combiner box with DC (not AC) MCB, surge protector out into an isolator switch (termed disconnect) before going into your inverter.
