[RE-wrenches] Battery switch 1, 2 or both for 65VDC

Sat Jan 2 11:44:31 EST 2021

Well. not according to the subject here  

This is not a temporary fix.
It really needs a 65V or higher to last. The Perko and other Chinese origin
are not going to last at 65Vdc. 

I was hoping that someone made even an
on/off switch that was 125Vdc and could take battery current of 250adc.
There already is the main disco breaker in the PDP. 

Thanks! I think I
will just add a second 250A disco. The app is too correct a design that had
too much battery in (2) strings for the solar or the 140ADC charger to
charge. Bad mistake above latitude 38. It was the year for that was it not?
Getting rid of the electric water heater did wonders also. 

Cheers!

I doubt you'll find anything in the normal marine rotary selector switch
configuration for above 50VDC. How many Amps you need? You could work up
your own relay system using these perhaps:

 But actually 2 of the
standard 125VDC Inverter 175/250 A discos in an enclosure is actually
pretty straightforward and readily available. I'd stick with that- You
could use either a Midnite Solar Mini-DC-X2 box

[6] (not cheap) or perhaps Outback Flexware DC switchboxes. The old Trace
DC switchbox also held two 125 vdc 175/250 A breakers.

 Happy New Year!

Jeff

I can't find a Battery switch for 1, 2 or both for 65VDC. In
the past I did this with (2) 125vdc 250adc disco's in a metal box. 

Anyone
seen one of these?    Dave Angelini Offgrid Solar
