Solar Mobile Security Trailers

FAQ: Solar Security Trailers

How much solar wattage does a security trailer need?

A standard 2–4 camera security trailer with LTE connectivity requires 400–800W of solar panels for sustainable 24/7 operation in most US climates. High-load configurations with 5G modems, PTZ cameras, LED strobes, and climate control may require 1,200–1,600W. In low-sun regions like the Pacific Northwest, always size for your worst-case winter sun hours, not summer averages.

What battery type is best for solar security trailers?

Lithium iron phosphate (LiFePO4) batteries are the industry standard for mobile security trailers. They offer 2,000–5,000 charge cycles (vs. 300–500 for AGM), an 80% usable depth of discharge, and reliable cold-weather performance down to -4°F. Always confirm your trailer uses lithium batteries — a 200Ah lithium pack has twice the usable capacity of a 200Ah AGM pack.

Can a solar trailer run indefinitely without generator backup?

In most US climates, a properly sized solar trailer can operate indefinitely without generator backup during spring, summer, and fall. In winter or overcast regions (Seattle, Chicago, northern tier states), even well-spec'd systems may need occasional generator top-off during extended cloudy periods. Confirm your trailer has a generator input port if deploying in low-sun areas for winter months.
