question

My first thought was, I would be happy when my PV Panels would produce power at night. :o)

But that is not the way it should be. Do you have double checked your wirings?

This could also be a faulty unit somehow.

I have done a double (and much more) wiring check. I don't remember seeing this earlier, the unit probably fall faulty.

But note that there is no error logged.

Is anyone from Victron reading this could explain the reason or confirm it should be a faulty unit?

Markus, you right, i will do last test this weekend, breaker, coupling diodes, etc... but according to me there is no alternative way to a warranty claim. Thanks for you support.

Please consider this screenshoot and be careful of the hour and you could see a night power production :)

I've experienced this myself in the past on my 150/100, but not recently. It seems to have 'gone away'. In most cases, at sometime during the night, it would step down to zero. I thought maybe capacitance somewhere, and dismissed it as being of any importance.

As an avid reader of Victon blogs, articles & tech specs, I have seen such things explained by suggesting they're 'within tolerance' for the 'best effort' attempts to measure such without adding to the cost of the kit. I expected so, and accepted that explanation gracefully.

But I too prefer accuracy, and 'one day' I'll add a BMV, and expect it to be accurate.. :)

So, I check everything : breaker, wiring, MC4 connectors, etc... Everything seems good.

@JohnC, currently my unit don't see any difference between day and night. The MPPT backlinght is always on (the sun is light up forever).

@Markus, this screen should be normal too in northern country during eternal day season ;)

As my unit doesn't work like that previously, it is probably partialy break down. I will see with my distributor how to do.

Thanks for your support guys and happy Near Year !
