The Battery Switch is accessible via the Sidebar → Battery Switch.
It allows controlled activation and deactivation of the entire battery system.

After booting, the BMS requires about 120 seconds for full initialization.
Only after this delay the green „Power On“ button becomes available.

⏳ During this time, the system runs internal checks and communication initialization.

• When „Power On“ is pressed, the BMS automatically performs an isolation test
• If the test passes, the precharge sequence starts, followed by activation of the positive and negative relays
• The system is now live and ready for operation

• Same flow as above, but without isolation test
• Relays are closed after a short delay and the inverter is powered up

Once relays are engaged, two buttons become visible:

• 🔴 Emergency Stop

Instantly disables all relays – use only in emergency situations ⚠️ Cuts power without any shutdown process. May lead to system faults if used during operation.

• 🔵 Shutdown

Recommended method for turning the system off Sends a clean shutdown signal to the inverter and safely disconnects all relays afterward

• State: Shows current switch/test state (e.g. Waiting, Testing Isolation, Ready, Error)
• Relays: Displays relay status (e.g. Open, Closed, Precharge, Error) 🔍 Always check both values before powering on or off the system manually.
