Charging leisure battery's with solar still connected (1 Viewer)

[gazpic]

Hi all
New to this forum. I have a 270 watt solar panel fixed onto my motor home. It's connected to my leisure battery via a charge controller . And power is taken from the battery not the controller .
Question... Is it ok to leave the charge controller still attached to the battery when charging via mains electric ?

You can leave it connected but the question is with that much solar power and bearing in mind the time of year why do you need to, unless you keep it under cover.

Mikeco, you hit the nail on the head. It's in my barn.

Far from the truth Mikeco !! Might have a barn and 10 acres, but no house
Living in the motor home Just a poor farm boy...

Woooooooooooooooooooooooooooooooooooo 10 acres, excellent room for a huuuuuuuuge meet. Have you got electric hook up we can use, or shall we bring our generators.

When I plug in to the EHU for 240v, my leisure battery charger also turns on. But I've also got a solar charger. I'm reasonably sure that whatever charger produces the highest voltage will provide the current, effectively blocking the other device.

I think my 240v charger switches to trickle charging at quite a low (voltage) threshold, so my solar controller is normally able to switch to a higher voltage, so it takes over... even if there's not much power to be had.

The way I picture it is two rivers. My mains charger is a broad (massive current) river and my solar river is a mere trickle of a stream. However, my solar river is higher up (higher voltage), so the water (electricity) flows from the solar river.

Spot on. And it depends where on it's smart charge cycle each charging source is at the time. Non of it matters though.
