Powerwall not charging as expected?
There could be a number of reasons why this is happening, but first of all, please ensure the powerwall has a good internet connection and that your time of use settings are correct.
Tesla use a platform called Opticaster to control how your battery operates. You can learn more about it here:
Tesla actively change and update Opticaster, which means your battery’s behaviour may vary over time.
If you’d prefer more direct control over your battery settings, some users choose third-party tools such as NetZero:
Please note, we have no affiliation with NetZero and cannot offer support or advice regarding its setup or use.
