SUN-20K-G04 20kW three phase string solar inverter

Reference: 25000008

The three-phase string inverters can be directly connected to the public grid (230/400V) without transformer. The SUN-20K-G04 inverter is equipped with integrated LCD display and function buttons, which are easy to operate and maintain, ideal for remote and under-resourced areas.

Additionally, the SUN-20K-G04 three-phase inverter has a built-in "0" injection function, thanks to the toroidal clamp included as a default accessory. It should be noted that this DEYE inverter is parallelizable, and can add up to 16 units.

The SUN-20K-G04 20kW three-phase string solar inverter has an input power of 26kW with a maximum efficiency of 98.60%. Besides, it has 2 MPPTs with an operating range between 200V and 800V for each MPPT.
