The HP-AHP20SA series provides specific protections against PV-related issues like over-current and short circuits:
PV Limit Current/Power Protection: If the actual charging current or power of the PV array exceeds its rated capacity, the system automatically regulates the charge of the battery according to the rated current or power.
PV Short Circuit Protection: In the event of a short circuit when the PV is not charging, the inverter/charger is designed to remain undamaged.
