Same day comparison, two events a mere 13 hrs apart.

06:30hrs worked perfectly (I believe) but this evening didn't - whatever settings they used made me draw from the grid instead of my batteries.

The only difference between the two events was SOC, I wonder if 43% caused this evening to fail.

Be good to know ahead of the two hour event tomorrow 🤞

We have two 16.1kWh Fogstar eco batteries and a 8kWh Solis inverter. I signed up to Axle Energy last month but haven't seen any grid events yet (we're in East Anglia).

On Sunday evening, after 11pm when everyone was tucked up in bed, the batteries dropped over 12% SOC within 15 minutes. There is not a single reason why this should happen, I know we did not use that much energy ourselves. Zero explanation.

Not only did this empty the batteries and start drawing expensive energy from the grid, the usual charging schedule at midnight didn't kick in, resulting in a full day Monday on grid-only supply. This may or may not be linked to the speed the batteries drain, but one of them went down to 6% SOC which triggered an alarm. The other, randomly, remained at 19% SOC.

My question is simple - what caused such a rapid demand for power resulting in empty batteries and a failed recharge? Did Axle take it??? I guarantee it was not domestic demand, I have nothing that can use that much energy that quickly.

Something doesn't stack up.
