Setting up an electric fence is no hard task when you have the S45B energiser from Thunderbird. It is solar-powered, which gives you the benefit of being portable and gives you a saving on electric bills. The S45B powers up to 5km making it handy for a range of tasks.

The new generation solar fence energiser has been enhanced to meet more requirements. This new version has a small LCD screen where you can see the voltage output of the solar energiser. It also displays the condition or status of the battery, which tells you when it is time to recharge. You can take it anywhere, so it is perfect for temporary or permanent fencing.

The S45B solar electric fence energiser also comes with its own inbuilt rechargeable battery and a carry handle for transportation.

Aside from the new digital display, it also has a magnetic switch, which means this unit is better sealed for all weather conditions. It has a mains AC charger, which also has a weatherproof port cover. This way, you do not have to be concerned about safety when you leave the system outdoors on rainy days.

The Thunderbird energiser also has an O-ring sealed enclosure, which provides extreme weather protection for the main electronics. The solar panel mounting uses a non-corrosive material, so it prevents rust from occurring, especially during the wet season.

This new version has enhanced efficiency and better electronics. It is why Thunderbird is confident and provides a six months warranty on damage due to lightning strikes. There is also another two-year manufacturer’s warranty for the product.

Mostly good

I've been using this energiser for 3 weeks now and so far so good. Unfortunately the plastic backing cracked slightly when I first mounted the unit on a star picket so I can't give this 5 stars.
