Yes, surveillance trailers include battery backup systems, and these batteries are essential to their operation.
Detailed Explanation-
Deep-cycle batteries (AGM, gel, or lithium) store the solar energy collected during the day.
-
They allow the trailer to run 24/7, including nighttime and cloudy periods.
-
Most trailers carry multiple batteries to provide 2–7 days of runtime with no sunlight.
-
A battery management system (BMS) protects the batteries from overcharging or over-discharging.
-
Some models add backup generators or plug-in charging options, but the battery bank is always the primary backup.
