The MPPT is connected to my 400W 45 volt solar array. I want to power a 12V pump from the load side terminals. A 12V battery is connected to the BATT terminals The load output won't work regardless of settings on the app unless I also connect the 12V pump directly to the battery. This is inconvenient since I don't want the pump running constantly. Any advice will be appriieciated1
The inrush current of the pump might be to high and is detected as a short circuit.
What power does the pump have?
Thanks for your reply. The pump specs shows it draws 180 watts and about 12-13 Volts DC when connected directly to the 12V battery. I will check amperage and let you know that reading later today.
By the way, the solar array is also way to big for this MPPT. You have almost double as much connected then recommended...
