My solar charge controller shows zero charging input some cloudy days. Has enyone experienced something similar? is it normal? i have attached two solar charger in my battery each of them providing power from a different string; i have also connected a smart battery sensor that provides data to the chargers. am i doing something wrong here? thanks for your input, cheers
as you can see, 4 days ago the load output from string 1 (2s2p) is zero while the output from string 2 (1 240w/24v panel) is 50 wh. This was a cloudy day with minimal electricity usage from the system, just a couple of lightbulbs. Both solar controllers are set at the same configuration (battery=>victron 2=>deep discharge).
the same thing happened a few days ago
the first controller is on float mode while the second is still in absorption. Any input is much appreciated, cheers.
Have a look at VE.Smart NetworkingSynchronised charging - further details.
Plz confirm.
in my previous setup i set up a network between the smart bat sense and the two controllers. I thought that this is the optimal setup so that both controllers receive data from the sensor. anyway i will let you know.cheers
Might be worth checking the settings on your controllers as well.
this is getting weird
the first controller reports a max battery voltage at 14.35v while the second one at 14.45v (i cannot be certain about the min bat reading )
both controllers are set in a network working in tandem
each controller has also the same settings
any input is wellcome.
Could be a poor battery connection causing resistance and a voltage drop.
The switch from absorption to float is based on time elapsed. Not sure if this can be different on the two controllers. If it is, it shouldn't be
