Hello Everyone
I am trying to run a small fridge (6 cuft) on battery connected in parallel with an MPPT solar charger . The settings of the controller are
Bulk Charge Voltage 14.4
Float Charge Voltage 13.5
My load is ~140W @ 12V and I have a Lead Acid 12V 140Ah battery attached in parallel with my load and the charger.
I've noticed with the load attached, the voltage drops about ~0.45V. I've metered the battery and the charger keeps the battery at about 14.0V indefinitely in Bulk Charging Mode, If I disconnect the load, the battery reaches float instantly. I'm assuming this isn't sustainable for the health of the battery, so I would want to make sure the battery is reaching all 3 phases correctly.
I'm not sure what the next logical step should be to get this set up working? Should I program the charger myself?
