3×40W
Voltage are for 12V use, x 2 for 24V use
SAFETY PROTECTION-
-Spark-free protection.
-Reverse polarity solar and battery connection.
-Again strever securrent from battery to solar panel at night.
-Over temperature protection with charging current de-rate.
-Transient over voltage protection, a varistor or transient voltage suppressor (TVS) at the solar
input and battery output against surge voltage.
-Safety and EMC compliance
