Description
The DC input works in the 500–1500 V range, so strings are assembled from more modules and fewer DC cables are needed in the field. Six trackers of 75 A each accept powerful modules with a higher operating current. The output voltage is 800 V AC, and a step-up transformer with a matching LV winding is selected for it. The efficiency reaches 99.03 %. Data is exchanged over the power cables via PLC, so separate communication lines to each inverter do not need to be laid. PID protection reduces module degradation caused by the potential relative to ground. The IP66 enclosure is mounted outdoors on the frame under the modules or near the substation.
How to choose
The rating is chosen for the power of the block and of the transformer, within 300–350 kVA. For enterprise roofs such a unit is too large, and the X3-MEGA G2 of 40–60 kW with an MPPT range of 180–1000 V is more suitable there. If the PV plant needs a battery and backup, look at hybrid models, for example the X3-HYBRID G4 with parallel operation up to 150 kW.

FAQ
What is the maximum DC voltage of the X3-GRAND HV inverter?
Up to 1500 V with an operating range of 500–1500 V. Strings are calculated so that the open-circuit voltage in frost does not exceed this limit.
How many MPPT inputs does the X3-GRAND HV have and what is the current per input?
6 MPPT inputs of 75 A each. This current is designed for large-format modules with a high operating current.
What is the output voltage of the X3-GRAND HV and with which transformer is it combined?
The output is 800 V AC, so a step-up transformer with an LV winding for exactly this voltage is used.
How does the X3-GRAND HV transmit data without a separate communication cable?
Via PLC, that is, the signal travels over the AC power cables. At a large PV plant this reduces the laying of low-current lines.
What is the efficiency of the X3-GRAND HV inverter?
The efficiency is 99.03 %, so conversion losses are small even at full power of 350 kVA.
