SoNick battery performance for cooking competition

GridEdge was recently asked to use our clean energy trailer with its Sodium nickel chloride (SoNick) battery to power a local cooking competition event to showcase local foods.

Originally the expectations were that we would be powering the PA and sound system and maybe a portable fridge. As the day got closer the requirements changed and instead of a portable fridge there were going to be 2 x 10 Amp eskys with ice so it would only be the PA and sound system that were being used that we needed to power.

We weren’t sure exactly how much power was going to be drawn and as we didn’t want to have the power disappear in the middle of the event we actually took another SoNick battery with us.  The 2 SoNick batteries were connected in parallel using an Anderson plug and even although 1 battery started at 100% of a 7.7 kWh capacity with the other 49% of a 5.7 kWh capacity the batteries connected with no issues whatsoever. I don’t believe there are any other battery technologies that can do this with any degree of safety.

The day got started and the first demonstration not only used the PA system but also a microwave and an electric oven. We closely monitored the batteries but there were no issues even although 30 – 40 amps were being drawn at the one time. There were 3 demonstrations held over the morning, jam making, sourdough bread making and granola cereal and slice making. The microwave and electric oven were used at various times over the morning.

In the afternoon there were a couple of cook-offs between chef’s from local restaurants that used different electrical equipment that they brought themselves.

As the day wore on the batteries were powering 

  • PA system
  • Electric esky’s
  • Microwave
  • Electric oven
  • Mix master
  • Vitamiser
  • Thermomix
  • Hand washing basin
  • As well as other smaller utensils.


At times there were 50 – 60 amps being drawn, on a fairly regular basis.

We were very pleased to find that even with all this equipment being run off the SoNick battery there were absolutely no power supply issues at all. In fact the chef’s weren’t even aware that their equipment was being powered solely by renewables and not by the grid or noisy diesel generators.

The GridEdge portable plug and play smart energy trailer storage solution replaces the need for diesel generators at markets and festivals. This means you can supply power to your event without any diesel fumes or noise normally associated with generator use.

The trailer uses the Sodium Nickel Chloride battery technology and has all the components necessary to make it a completely portable power source. It also has solar panels incorporated to keep the batteries power topped up during the day.

The trailer can be completely recharged off site at a time when power is not needed to be generated.
