ESI-8K-T1
Product information "ESI-8K-T1"
It is currently approved for use in Germany, Poland, Belgium, and Hungary.
This hybrid inverter is designed for the Sofar PowerAll All-in-One system. However, it can also be operated as a standalone device.
The scope of delivery includes an inline meter up to 80 A. For higher currents, suitable measuring transformers must be added.
If more than three storage modules are used, they must be installed as a second tower. The Sofar PowerAll Extension Kit is also required.
The new ESI series hybrid inverters from Sofar Solar can be connected to up to six of the current BTS 5K storage modules to create an all-in-one system. The three-phase T1 version is available in power classes from 5 to 12 kW. With 20 amps of input current on each of the three MPP trackers, complete Type 2 surge protection, AFCI arc detection, and an integrated EMS system, they leave little to be desired. Backup power is also available via the standard backup connection with a switching time of <10 ms. A direct-measuring inline meter, WiFi dongle, and the base for the storage modules are included in the scope of delivery and simplify installation.
