SRNE 60kW Three-Phase Hybrid Inverter Description
SRNE 60kW Three-Phase Hybrid Inverter
The Ultimate Commercial & Industrial (C&I) Energy Solution
The IESP600SH3 is a high-voltage, three-phase hybrid inverter designed specifically for large-scale commercial power needs. It serves as a central energy hub for factories, office buildings, and farms, managing massive solar arrays and high-capacity battery storage with industrial-grade precision.
Core Engineering Highlights
-
4 Independent MPPT Trackers: Allows for complex roof layouts. You can install panels facing four different directions (North, South, East, West) without losing efficiency due to shading or orientation.
-
Ultra-High Voltage Battery Support: Works with high-voltage battery systems (up to 820V DC). High-voltage architecture reduces cable thickness and energy loss, making the system safer and more efficient for industrial use.
-
DC Over-sizing (1.5x to 1.8x): Supports up to 90kW–108kW of Solar PV input. This allows the system to reach its full 60kW output even in low-light or overcast conditions.
-
100% Unbalanced Load Capability: Unlike standard inverters, this unit can handle 100% load on one phase while the others are idle, preventing system trips in buildings with uneven electrical distribution.
-
Parallel Scalability: Support for 1 to 9 units in parallel, allowing you to scale your system from 60kW up to a massive 600kW for heavy industrial demands
