solar on/off switch

[TCG]

as anyone fitted one of these, are they any good or can you advise of a better switch for my solar panels (for the winter)

I use something similar but only really to disconnect if working on something. Otherwise why would I turn off the solar in any season?

want to reduce the amount of charge to lithium batteries in the winter (keep them about 80%)

If you have a victron Bluetooth MPPT you can turn it off in victron connect if not just use a cheap double pole MCB and use as a switch should be DC rated but the amount of times you use it shouldn't be a problem if not.

I have the same as the OP picture. There have been criticisms of the quality although I've had no problems with mine.

Mine is very similar but I intend to replace it with a midi fuse. Not as convenient but much safer. Those Chinese circuit breakers aren't made to any standard and I don't like leaving it unattended. Funsters have had them fail.

I've used one for years to isolate the solar panels.
I also use two of them on my B2B charge

If you have an app for the batteries you should be able to change the SOC on it

that looks a bit more robust is that battery switch fused

No fuse required, the panel can only deliver 10 amps and the cable can handle that easily
