Thanks, that was it, default was 100% on Batteries. Any suggestions for that number during non critical times. I currently set it to 50% and now they are giving back. Sweet!
It’s really a decision that you need to make for your own situation. The higher the reserve percentage the more power you will have available in the event of an outage, but the less power you will have available for day to day use.
If you don’t have outages frequently and/or are OK with the possibility of running out of power in the event of an extended outage, then you could set the number lower to take advantage of the load shifting capability of the powerwalls.
It’s also worth spending some time playing around with the system to get an idea about how much power you use. Maybe set the reserve way down tonight and see how much power it takes to power your house overnight. If, say, you discover that you only need 30% of the powerwalls capacity to power your house through the night then you could set your reserve around 35 or 40% and know that no matter when the power fails you should be able to make it through the night and into the next day when the sun comes out.
I know that some people will also vary the reserve based on what’s happening around them. If you are affected by the wildfires, for example, and know that your solar system isn’t producing as much power as normal and/or it is more likely that your power might fail, then maybe you could bump the reserve up a bit. In the winter if you have gas heat and you aren’t running your air conditioner at all then your house might be using less power than it would in the summer, so you might want to bump the reserve down a bit.
