PV inverter adjustment time

How long do PV inverters last?

Inverters in the past often lasted for much shorter periods of time, sometimes as briefly as five years. However, most new products are rated to last much longer, with SolarEdge Technologies offering a 12-year warranty on its inverters, for example. Capacitor failure is a significant cause of malfunctions in PV inverters.

How do I change the parameter settings of the inverter?

Change the parameter settings as described in the user manual for the device or the software. In the first 10 operational hours you can set the inverter types SB 3000TL-20 / 4000TL-20 / SB 5000TL-20 using the rotary code switch to island grid/backup operation ("off-grid").

How do I change the grid parameters in the PV inverter?

For changing the grid relevant parameters in the PV inverter you need a special access code, the installer code. To obtain your personal code, contact the Sunny Island Hotline by calling +49 561 9522 399 or sending an e-mail to [email protected]. Change the parameter settings as described in the user manual for the device or the software.

How many PV inverters can be connected to an as-box XL?

Connect a maximum of 2 PV inverters to an AS-Box S! In a Sunny Backup system XL, the nominal AC power of the PV inverter may only be twice as large as the sum of the nominal AC power of the backup inverters. You can order all PV inverters with default island grid or backup parameters from SMA Solar Technology. WARNING!
