Best Solar Electric fence

I smell BS............ 1.9J (stored energy), wonder what the output Joules are?

C cell Batteries??? Are what in the name of *** are they going to add?

Night time power saving mode?? wonder what the output drops to then especially with 20KM of fence?

run 20KM of fence all year round? I have some doubts.

Likewise, fragmented farm here, I'd no issues keeping in bull fenced in to 20 Acres divided into paddocks with one of these.

I also bought the fence unit by itself and a more powerful one, I run these 2 on larger 100W panels along with 12V water pumps to keep the drinkers going as well as keeping stock including bulls in.

The most important part is that you have enough Joules for the Fence length/Area you want to cover, the 0.5J models in some of the previous posts are great for short runs, strip grazing (even with bulls) and are light / portable, more powerful units will be heavy with large car/tractor type batteries.

The biggest issues lads have is trying to use the wrong units in the wrong place and not using adequate earth bars for long runs. There is no point comparing a 0.5J solar fence to a 10J mains fence. Fence units are usually rated in Stored Joules and/or Output Joules, so when comparing units compare like for like (Output joules are a better indicator of power, if only rated in stored Joules then Output Joules is likely 2/3 of that). Most decent units will produce 9,000 to 11,000 Volts but real world earthing from vegetation and poor connections will see a lower voltage on the line. 3,000V will keep most stock in but it would be nice to see at least double that where bulls are concerned. A solar unit will be "almost" as good as the equivalent mains unit but they will perform better in bright sunny weather compared to dull days or night time, so don't skimp on the size, just go a little larger.
