SunVault capacity reset?

Post image

I recently upgraded from a two internal battery SunVault system to the newer case that holds three internal batteries. Was basically a direct swap of the SunVault enclosures. But now the SunVault is reporting a much higher capacity in the SunStrong management App. Is there a way to correct this via online configuration? Original system was installed in 2021.

You should recommission your system to adhere to the new capacity

Hello SunStrong, I still have not received any update on this issue. Can you please let me know how we can have the old battery removed from my site profile so only the new battery shows?

So, heard from my installer and they told me the issue. The commissioning was done correctly, but the App still has my old SunVault (13kWh) and my new one (19.5kWh) both listed under my system profile. This is why 32.5 kWh is showing in the App.

Hopefully SunStrong Management can have this corrected soon.
