Do I need to manually control my system to participate in events?

Am I locked into the program once I enroll or can I opt out later?

You can opt out of specific events. You can also request to withdraw your system from the program at the end of a season.

Will this impact my battery warranty?​​

No. Participation in the Energy Storage Solutions Program does not impact Sol-Ark equipment warranties.
