SolaX X3-HYBRID G4 is a current three-phase hybrid inverter family for solar, high-voltage batteries and an EPS output. Six codes cover rated AC outputs from 5 kW to 15 kW.

Tracker arrangement changes above 6 kW

Every model has two MPPTs. The 5 kW and 6 kW units provide one string input and a 16 A limit on each tracker. From 8 kW upwards, the first tracker accepts two strings and has a 28 A aggregate limit, while the second remains one string at 16 A.

The 28 A limit is shared across the first tracker’s two string inputs. It does not mean one solar string may use the full 28 A independently, and string voltage still has to remain inside the 180 V to 950 V tracker range and 1,000 V absolute input limit.

The battery port covers lithium and lead-acid batteries across 120 V to 800 V, with a 30 A maximum charge or discharge current. A voltage match is only one compatibility condition; the approved battery family, module count and communications also have to match the exact inverter revision.

Three-phase and EPS records

Unbalanced output reaches 5 kW per phase. EPS is code-specific: rated output follows the six inverter classes, while ten-second peak values range from 12 kVA to 22.5 kVA. Switching takes less than 10 ms.

The output schedule does not define the property’s backed-up circuits or external switching. Phase allocation, earthing, isolation and simultaneous loads are installation-design records.

X3-Hybrid G4 has five years of standard cover, upgraded to ten years with a qualifying SolaXCloud connection and successful generation-data upload. The exact serial number and applicable terms determine the dates.
