Solar controller in error when exceeding 100v DC on PV array. Max Voc controller: 145v

[subjero]

Hi guys,

I know it is not the best solar charge controller, but i have a jing/jng jn-mppt-bl controller and the controller is in error every time the PV voltage is over 100vdc.

PV array open circuit voltage range should be: 80-145V (48V battery system) according to page 8 in the manual:


I want to connect 3 panels in serie, but when i do the voltage is +-110v dc and the controller is shutoff.
When i connect 2 in series the voltage is +-80v dc (and lower when charging) and all is working fine.

Do i have a faulty controller, do i need to make a setting change? I am lost here.

Thanks and kind regards,

Your system is 48 volts?
What is the Voc rating of your panels and how are they wired?

Either faulty or it can actually only support around 100V? Is it one of these?

One more vote for a bad product.

48v battery, 38v Voc panel and 3 in series.

One of these. The 60A BL version
