The three-phase string inverters can be directly connected to the public grid (230/400V) without transformer. The SUN-50K-G03 inverter is equipped with integrated LCD display and function buttons, which are easy to use and maintain, ideal for remote and under-resourced areas.
Besides, the SUN-50K-G03 three-phase inverter has a built-in "0" injection function, thanks to the toroidal clamp included as default accessory. It should be noted that this DEYE inverter is also parallelizable, being able to add up to 16 units.
String connection refers to the connection in series of several solar panels that generate direct current, which allows the inverter to convert the energy into alternating current that can be delivered to the electric grid.
The SUN-50K-G03 50kW three-phase string solar inverter has an input power of 65kW and a maximum efficiency of 98.70%. Besides, it has 4 MPPTs with an operating range between 200V and 850V for each MPPT.
An important highlight is that the SUN-50K-G03 inverter from DEYE by Eastech comes with both the AFCI card and the Anti PID Module included as standard. The AFCI card prevents and minimises safety accidents arising from DC arching. By showing the string number or specific string on which this arcing alarm has happened, it helps service operators to solve malfunctions.
The Anti PID module prevents the effect of Potential Induced Degradation (PID). This module takes power from the grid and increases the 500V voltage at the negative pole of the string, which reverses the PID effect and reduces the energy loss incurred.
