Energizers: Plug-in, Battery or Solar

(left to right) Battery energizer, plug-in energizer and solar energizer. 

When choosing an energizer here is one very basic thing to keep in mind—is it going to be a battery, plug-in or solar energizer. Note: solar energizers are battery energizers with added bells and whistles. 

With that in mind, what are the differences between the two basic types?
Plug-in—power source is a 110v outlet. Permanently located. 
Battery—power source is a 12v battery. Easy to relocate. 
  • A plug-in energizer is left in one location (usually close to an outlet). An insulated cable is used to carry the pulse from the energizer to the fence. 
  • Battery energizers are typically set close to the fence and away from any convenient outlets. They draw off a 12v battery. The pulse travels through a short wiring harness to the fence. 
  • Battery energizers cost more overall b/c of the need to purchase batteries and a battery charger. 
What about solar energizers?
Solar energizers are extremely convenient to use. Fences can be set up in the middle of nowhere. Depending on hours of usable sunlight, batteries rarely need recharging (but do keep an eye on them). 
The downside is the cost. The battery, panel, case, regulator (for high output panels) add to the price tag. That and if the sun doesn't shine for multiple days (the PRS units are sized for a 4-day reserve) the voltage on the fence will drop as the battery drops below a 40% charge). But for many convenience outweighs costs, hence why solar energizers are popular. 

Which to use?
If the energizer gets to stay in one place—we recommend plug-in energizers at every opportunity. No batteries + no reliance on sun = less hassle. 

If portability is needed, use a battery energizer. 

If portability with added convenience is desired, solar is best.
