The Solax X3-HYBRID-8.0-D is an 8 kW three-phase hybrid inverter with integrated DC switch, part of the X3-Hybrid G4 series. Designed for advanced residential and commercial photovoltaic systems with three-phase users, it supports high-voltage (HV) Solax Triple Power batteries and offers a maximum efficiency of 98.0% with EPS backup function in less than 10 ms.
X3-HYBRID-8.0-D: Why Choose the 8 kW Three-Phase
Compared to the 6 kW model, the 8 kW inverter is the right choice for three-phase users with higher consumption — properties with heat pumps, large air conditioning systems, warehouses, and small businesses. It supports a maximum absorbed photovoltaic power of 12,000 Wp (150% oversizing) and the EPS output can reach peaks of 12,000 VA for 60 seconds in backup mode, ensuring continuity even for critical loads.

Main Features
The X3-HYBRID-8.0-D supports 5 operating modes with 2 programmable charging periods, VPP-ready functionality, and unbalanced three-phase output (up to 50% of nominal power on a single phase). Configuration via U-disk and Wi-Fi/Ethernet monitoring through SolaxCloud simplify commissioning and remote management. Parallel operation up to 150 kW allows the system to be scaled for medium-sized applications. The compatible battery is the Solax Triple Power HV (5.8 kWh per module), with expandable capacity up to 46.4 kWh and compatibility with CEI 0-21 and CEI 0-16 certifications.
Frequently Asked Questions
Is the Solax X3-HYBRID-8.0-D suitable for a three-phase user with a heat pump?
Yes, the 8 kW nominal three-phase power easily manages the peak absorption of 5-8 kW air-water heat pumps. The included CT allows real-time load control (response within 0.3 s), automatically optimizing the priority between photovoltaic, battery, and grid.
How many batteries can be connected to the X3-HYBRID-8.0-D?
It supports Solax Triple Power HV batteries in the 180–650 V range. Multiple modules can be connected for capacity up to 46.4 kWh. At least 2 modules are required to reach the minimum voltage of 180 V. Compatible batteries include the T-BAT-SYS-HV and TP-HS50 series.
What is the difference between X3-HYBRID-8.0-D and X3-HYBRID-6.0-D?
The main difference is the nominal AC power (8 kW vs 6 kW) and the maximum PV power absorbed (12,000 Wp vs 10,000 Wp). All other features — MPPT, battery compatibility, EPS, parallel operation — are identical. The 8K model is recommended for systems with three-phase loads above 6 kW or PV fields from 8-12 kWp.
Is the X3-HYBRID-8.0-D certified CEI 0-21 and CEI 0-16 for the Italian grid?
Yes, like all models in the X3-Hybrid G4 series, the X3-HYBRID-8.0-D is certified CEI 0-21 (low voltage) and CEI 0-16 (medium voltage), fundamental requirements for connection to the Italian grid and for GSE procedures related to photovoltaic incentives.
Does the X3-HYBRID-8.0-D also work off-grid and in parallel with other inverters?
Yes, on both fronts. In EPS mode, it powers loads in case of blackout with switching in less than 10 ms. It supports parallel operation on-grid and off-grid up to a total of 150 kW, combining multiple X3-Hybrid units for medium-scale installations.
