FETY PROTECTION -
-Spark-free protection.
-Reverse polarity solar and battery connection.
-Against reverse current from battery to solar panel at night.
-Over temperature protection with charging current de-rate.
-Transient overvoltage protection, a varistor or transient voltage suppressor (TVS) at the solar input
and battery output against surge voltage.
-Safety and EMC compliance
