Sofar Solar 8 kVA three-phase hybrid inverter - HYD-KTL-3PH
The HYD 5K...20KTL-3PH is a versatile three-phase hybrid inverter for solar and storage applications. During grid failures, it can provide up to 20 kW of unbalanced three-phase emergency power supply (EPS) in 10 ms thanks to its integrated EPS port.
Two MPPTs and two independent battery ports (on models 10K to 20KTL) enable multiple battery capacity configurations in 2.5 kWh steps.
Up to 10 inverters can be connected in parallel on the EPS and AC port, making this device ideal for microgrid installations (on or off-grid).
The integrated energy management system features several user-friendly modes, optimizing the user experience, including an automatic self-use mode. Users can also define different time and/or date ranges, or rules for the day of the week.
All modes can be easily configured on the large LCD display. In particular, this inverter is compatible with SofarSolar's AMASS Store high-voltage battery unit (GTX 3000-H). A WiFi stick is supplied with the inverter, for easy connection to the Sofar monitoring portal.
