Description
Export limiting works in both generations, so the inverter is installed where selling to the grid is prohibited or restricted by the contract. The PRO G3 is built on SiC transistors and reaches a maximum efficiency of 98.8%, which means less heat in the housing at a 30 kW plant. The G3 has three MPPTs with up to 40 A, so two strings or high-power panels are connected in parallel to one tracker. For the G3 there is an AI-AFCI option, which detects arc faults in DC lines and de-energizes the circuit. The G2 housing is rated IP66 and is installed outdoors, on a wall or under the panels.
How to choose
The boundary between the generations is set by power. Up to 20 kW only the PRO G2 is available; in the 20–30 kW range both exist, and then the G3 wins with higher efficiency, a 40 A tracker current and the AI-AFCI option. If battery backup is needed, a grid-tied inverter will not do, and the hybrid X3-HYBRID G4 rated 5–15 kW is taken. For industrial plants of hundreds of kilowatts there is the X3-GRAND HV with DC voltage up to 1500 V and a power of 300–350 kVA.

FAQ
What is the efficiency of the X3-PRO G3?
The maximum efficiency of the PRO G3 is 98.8%. The power stage is built on silicon carbide (SiC).
Can grid export be limited on the X3-PRO?
Yes, the export limiting function is built into the series. It is set up when the grid contract does not provide for selling electricity.
How many MPPTs does the X3-PRO G3 have and what is the current per tracker?
Three MPPTs, with up to 40 A each. This is designed for powerful panels with a high operating current.
What is AI-AFCI in the X3-PRO G3 inverter?
It is an option for detecting an arc fault in the DC circuit. The inverter disconnects the string when an arc appears, which reduces the risk of a fire on the roof.
