system not longer working after power outrage
Since a power outage, my solar panel system is no longer working.

Inverter: Solis RHI-5K-48ES-5G
Battery: Fox ESS LV5200

What I see:

- The inverter screen remains black/off
- The battery shows a red warning light (alarm) that stays on
- Restarting and resetting does not solve the issue

What can i to best
