Solis S6-EH3P15K02-NV-YD-L 15kW Three-Phase Hybrid Solar Inverter

Important PV Capacity Correction

The customer-provided 20,000W PV figure is not the official maximum for this exact model. Official Solis documentation states:

• Recommended maximum PV array size: 30kW
• Maximum usable PV input: approximately 24kW (160% of the 15kW rated inverter power)

Product Description

The Solis S6-EH3P15K02-NV-YD-L is a powerful 15kW three-phase low-voltage hybrid solar inverter designed for large residential and commercial energy-storage installations. It supports 40–60V lithium-ion and lead-acid battery systems, generator integration, grid-connected operation and high-performance backup power.

The inverter features two MPPT trackers with four PV string inputs, up to 290A battery charge and discharge current, fast backup switching in under 10 milliseconds and 200% backup overload capability for 10 seconds. Its IP66-rated enclosure, intelligent fan cooling and wide operating-temperature range make it suitable for demanding solar installations.

A large 7-inch LCD display, Bluetooth, Wi-Fi, LAN, CAN and RS485 communication provide easy commissioning, monitoring and battery integration. The system also supports three-phase unbalanced loads, generator control and the parallel operation of up to six compatible inverters.
