Page 13: String Fuses
Ungrounded System: The DC lines of this PV system are not grounded and may be en- ergized. String Fuses You can give solar modules extra protection by using string fuses in the Fronius Primo 10- 15 kW. Crucial for the fuse protection of the solar modules is the maximum short circuit current I of the relevant solar module. - Page 14 Nominal current of the fuse Short circuit current for standard test conditions (STC) according to solar module data sheet Nominal voltage of the fuse NOTE! The nominal current value of the fuse must not exceed the maximum fuse protection value specified in the solar module manufacturer's data sheet. If a max- imum fuse protection value is not specified, please request it from the solar mod- ule manufacturer.

Questions and answers
I can not see what the soler is doing. We have lost blue tooth and can't get it back. We have 22 panels on the roof and our electric bill is very high. the screen today is showing 4.2 with a green light on the screen
A display of "4.2" and a green light on the Fronius inverter indicates normal operation and firmware version 4.2. There is no fault with the inverter itself.
If Bluetooth connectivity is not working, it may be due to outdated firmware or incompatible settings. To restore Bluetooth connectivity:
1. Use a suitable USB stick to update the inverter firmware via the USB port.
2. Ensure that Bluetooth is enabled in the inverter settings.
3. Restart the inverter by switching the AC circuit breaker off and on.
If the issue persists, check for hardware compatibility or contact a qualified service technician.
