My Battery charges for a short time just before 10pm before charging again from a lower rate after midnight?
This is an expected behaviour, the software makes it predictions at least every 24 hours, and these are always for the next 48 hours. However with the Agile tariff, the rates are not yet known for the full 48 period, so the software will assume that the current rates will repeat again the next day.
Because the software makes it predictions and sets a new plan typically around 10pm each night, this can sometime result in a short charge just before 10pm when the tariff rates are assumed to be the lowest available, then at 10pm, once the actual tariff is input and new predictions made, any further charging should take place at the very cheapest rate usually after midnight.
My battery does not fully discharge during a peak rate period.
If you are on an Agile tariff, the battery may reserve some power for the very highest rate during the overall peak of 4pm and 7pm. The most expensive rate is not always at the beginning, this can result in the battery not fully discharging straight after 4pm, but reserve power for later on in the peak rate period.
My battery continued to discharge through an off-peak period.
The battery may continue to discharge through a low-rate period rather than charge if it predicts there is sufficient charge available to cover your consumption for the duration as well as high solar predicted for the following day. This may mean that if you unexpectedly turn on a high consumption device at an off peak time, such a charging an EV, the battery may discharge rather than allow the consumption to come entirely from the grid.
To prevent this we would advice using any high consumption devices in a regular pattern or to use the device for shorter periods.
The battery is not charging from excess solar during the day, causing solar to be exported to the grid.
If low solar generation has been predicted and there isn’t excess expected to charge the battery ahead of a peak rate, the battery may stay idle to preserve any charge rather than risk it accidentally being discharged. The battery will retain the correct amount of power to cover the predicted consumption, if it has already reached that level of charge then any additional unexpected solar may be diverted back to the grid.
The battery has not fully charge from grid overnight.
Our software will try and minimise the grid charging and allow room to charge from any predicted free solar energy as much as possible, it will not fully charge during each off-peak period just in case. If the generation levels turn out lower than predicted, the software will re-plan to take advantage of any remaining lower rate energy where possible, but this may not be possible depending on your tariff.
The battery is charging from the grid sporadically during the day.
The software will plan to slowly increase the level of charge in the battery across the day if there is a higher rate peak period expected in the afternoon.
The battery is discharging at maximum rate sporadically during the day with energy being sent back to the grid.
If you have provided the support team with a suitable SEG tariff, your battery may be set to discharge at optimal times when export rates are high
The battery is fully charging from the grid overnight and not leaving any room to store additional solar, leading to solar generation being wasted/sent back to grid during the day.
The predictions for your upcoming consumption are based on your previous 14 days of data, with more emphasis placed on 1 day and 7 days previous, if your consumption was very high 7 days ago the software may predict this to happen again and fully charge from the grid in advance. The software can re-plan during the day but the battery may already be fully charged by that point, meaning any excess solar is then diverted to the grid.
