Gallagher S100 Solar Fence Energizer

Excellent product. Had it now for 1.5 years with no issues, never runs out of charge, strong shock- keeps all ground predators away from the coop. Highly recommend.

This Gallagher S100 electric fence charger is absolutely incredible - the heart of our entire cattle fencing system! After running beef cattle for years with various fence chargers, I can confidently say the S100 is in a league of its own. This unit powers our entire perimeter fencing system flawlessly, keeping our herd contained with consistent, reliable voltage that our cattle respect every single time. Why the S100 is outstanding: • Incredible power output - Maintains strong voltage across our entire 40-acre perimeter • Rock-solid reliability - Zero failures in 18 months of continuous operation • Weather resistant housing - Handles everything from ice storms to blazing summer heat • Easy monitoring - Clear voltage display lets you know system status at a glance • Gallagher engineering - Built for serious ranching, not hobby farms Cattle rancher’s best friend: This charger delivers the consistent punch needed to keep 1,200+ pound animals where they belong. Our beef herd learned quickly to respect the fence line, and we haven’t had a single breakout since installation. The S100 maintains hot voltage even with some vegetation contact - something cheaper units just can’t handle. Performance that counts: • Powers multiple wire strands across extensive perimeter without voltage drop • Handles ground moisture variations that kill lesser chargers • Consistent performance regardless of weather conditions • Built-in lightning protection gives peace of mind during storms • Energy efficient operation keeps electric costs reasonable Professional-grade results: Other ranchers and our livestock extension agent are always impressed with how well our fencing system performs. The S100’s consistent power delivery creates that invisible barrier that’s absolutely critical for effective pasture management. Investment grade quality - Yes, it costs more than basic units, but when your cattle operation depends on reliable containment, you need equipment you can trust 24/7/365. This charger pays for itself by preventing costly breakouts and maintaining proper rotational grazing. Pro tip: Proper grounding is crucial - invest in quality ground rods and the S100 will reward you with flawless performance. Whether you’re running stocker cattle, cow-calf operations, or finishing cattle, the S100 provides the reliable power backbone your electric fencing system needs. Our cattle stay put, our grass management stays on schedule, and we have complete confidence in our perimeter security. Essential for serious cattle operations - the gold standard of fence chargers!

We use Gallagher products and they are all reliable. We use this one for our highland cattle to split up a pasture into four areas using electric "gates". Easy to set up and take down

So I can say from personal experience that this charger delivers a punch. Like any other solar panel, you'll need to give it a wipe down every so often to maximize charge benefit.

Great fencer to keep the cows in. Just wish the spark was a little hotter.

I don't mind paying 3-4 times the price of competitors but this charger is garbage. I have three triangulated ground rod on leads than a mile of total fence and it wouldn't zap a mosquito. The first day all my cows walked right through it. If you have cattle you know they know that a fence is hot and they stopped, nosed it, and walked right through. The fence tested they provide said the fence was at full strength with no issues. Poor charger don't was the extra cash!!

I had great sunny weather the first 3 days after installing this! I kept it off, facing south (I live in MA), and charging in the sunlight before turning it on. It’s connected to 300’ of premier 1 poultry netting with barely any vegetation touching the fence. The soil is damp and a 3’ grounding rod is connected to the energizer. I feel like I’ve done everything right and we have had mostly sunny days, but after about 5 days of working me the battery being solid green it turned solid red. Very frustrating. I’ll have to look into a return, as I can’t leave my animals on pasture without an energizer while I charge the battery indoors.

Great product!
