Solis S6-EH3P15K-H Hybrid Inverter 15 kW Three-Phase
The Solis S6-EH3P15K-H is a 15 kW three-phase hybrid inverter from the high-voltage S6 series, suitable for advanced residential and commercial photovoltaic systems with lithium storage from 120 to 800 V. It has 4 MPPT trackers with a 200-850 V range and 20 A per input, for usable photovoltaic power of up to 24 kW (160% of the rated AC power).
Battery charging and discharging power reaches 15 kW with 50 A, while the backup output delivers full rated power with a peak equal to 1.6 times the rated power for 10 s and switchover in less than 10 ms. Maximum efficiency is 97.7% (97.5% European). The IP66 enclosure with intelligent fan cooling, the 7-inch LCD display, Bluetooth and the CAN, RS485 and Ethernet ports complete the package. The inverter is CEI 0-21 and CEI 0-16 certified.
