When one installs a Solar System you have to have that installation certified by an Electrician with a Wireman’s License – no matter whether it is a Grid Tie only, Hybrid or even Off-Grid system.
When you install a Grid Tie or Hybrid system there are certain forms that you must fill in for your municipality. In turn the municipality will come and install a Smart (or 4 Quadrant) meter which places you on a Time of Use (ToU) Scale AND you will be charged a monthly ‘admin’ fee. Under ToU you will be charged one of three tariffs depending on the time of day AND season that you use electricity from the grid. Those tariffs (except for the Peak Tariff) are all much less than what you pay on the highest IBT presently AND will be less from 2023.
With the Tesla Powerwall your installer will programme the different Time of Use Parameters into the management software of the Powerwall.
And NOW comes the bottom line:
- The changeover from Winter to Summer tariffs happens at the start of 1 September (midnight on 31 August)
- The Summer Tariff is cheaper than the Winter tariff
Most Tesla Powerwalls in South Africa will have been programmed to charge the battery from the grid (if required) at the cheapest tariff which starts at 10:00 pm at night.
NOW – with the changeover to Summer Tariff last night all Powerwalls (if pre-programmed with the ToU tariffs) that needed topping up from the Grid did NOT draw from the Grid at 10:00 pm on 31 August 2022 – they WAITED until just after midnight so as to only start charging at the LOWER tariff two hours later in the Summer season tariff.
A Smart, NO – a very smart algorithm that saves you money whenever it can!
