My two 410W solar panels and mppt 100/50 controller has been working great. This sunny morning, it is reading 0w eventhough the voltage difference is ok and it says it is in the bulk state. (The cerbo shows the inverter in float state and weare hooked up to 30amp shore power.) However. It was really cold last night and now only 1 degrees C. Is there a problem??? Please help.
Thanks!
Some additional info - we have it set for Lithium batteries. Also the blue light on the controller is blinking - "Note (*1): The bulk led will blink briefly every 3 seconds when the system is powered but there is insufficient power to start charging."... But there seems to be plenty of power to start charging. Can anyone please explain???
If you use the Lithium preset it stops charging below 5°C.
Look at your settings.
Also look at the datasheet of your batteries.
Yep! Thanks so much.
I might need to edit the setting since the batteries say they are good to 0C and it took over half the day to heat up to 5C.
