What precaution should be taken when connecting a solar panel to a lithium iron phosphate battery?
Ground the solar panel outer metal framework
Ensure the battery is placed terminals-up
A series resistor must be in place
The solar panel must have a charge controller✓پاسخ درست
توضیح
A lithium iron phosphate pack must be charged to a defined voltage with a controlled current and then held or terminated, and an unregulated panel can push its open-circuit voltage well beyond that limit. A charge controller matched to the chemistry enforces the correct profile, which a plain blocking diode cannot do.
