Off-grid power for the loads a cable never reached

The two loads that live past the last socket

Perimeter fencing and remote monitoring share one problem: no mains, no truck roll, and a failure that is only discovered when something gets out or a camera goes dark. Both are solved by the same discipline — size the panel for the worst month, not the average year.

What actually decides the specification

• Joules, not watts. A fence energizer delivers a short pulse. Output in joules and the voltage on the line decide whether the animal respects it; the battery only decides how long it keeps doing that.
• Vegetation load. Grass touching the wire drains energy continuously. A run that works in dry season can halve its effective length when the grass comes up.
• Insulation and earth. Most “weak energizer” complaints are an earth rod with a bad connection. We specify the earth return before the output class.

What we make for this

PE-FE11 is the stock solar energizer: panel bonded to the body, no separate frame, no cable gland to leak, four colourways for the shelf. PE-FE30 is the higher-output build for long runs and dry vegetation. For remote cameras and gateways, the same panel-and-battery approach runs a 12 Vdc rail with a PE-DU18 buffer in front of the load.

Battery and panel are sized to your climate zone and your overcast tolerance, and confirmed on the build sheet. CE, RoHS and UN38.3 documentation ships with the units; the fence output is quoted by class, with test data rather than a brochure figure.
