2km Solar Electric Fence Energiser with Battery

Newly released new generation of solar energisers from Thunderbird Australia.
Thunderbird’s new Generation Solar Fence Energisers now include the following improvements:

• Magnetic switch eliminates the need for holes through the case
• A.C. Mains charger port is now covered from the weather
• Now available with low and high power levels
• O-Ring sealed enclosure provides superior weather protection
• Supplied with earth and fence leads
• Non corrosive material for solar panel mounting
• Improved efficiency through improved electronics

Model S18B powers up to 1.5 km, ideal for small enclosures

Note that these energisers contain a sealed lead acid battery (SLA). SLA batteries do not like to be stored in a discharged condition.  Storing an SLA battery in a discharged state causes sulphation of the negative electrode which, when left for a month or so, basically kills the battery.  It cannot be recovered from this state.

Periodically fully charging the battery is essential in preventing this sulphation from occurring.
