X3-HYBRID-15.0-D
The Solax X3-HYBRID-15.0-D is a 15 kW three-phase hybrid inverter from the X3-Hybrid G4 series, designed for advanced residential photovoltaic systems with high-voltage (HV) battery storage. It features 2 MPPT, integrated EPS backup, 200% PV oversizing, CT included, and a 10-year warranty.
The Solax X3-HYBRID-15.0-D is a 15 kW three-phase hybrid inverter from the X3-Hybrid G4 series. It is the flagship model of the G4 range for the residential and light commercial market: it manages photovoltaic production, charging/discharging of high-voltage (HV) batteries, and ensures power continuity via the EPS function in case of blackout.
The most powerful in the X3-Hybrid G4 range
The 15.0-D model is the top of the X3-Hybrid G4 series in the standard voltage configuration. With 2 MPPT and 200% oversizing, it manages up to 30 kWp of PV generator. The maximum battery current of 30 A ensures fast charge/discharge cycles, while the included CT natively enables the zero export function. The 10-year warranty reflects Solax's build quality on the hybrid range.

Frequently Asked Questions
When should I choose the X3-HYBRID-15.0-D instead of the X3-ULT-15K?
The X3-Hybrid G4 15 kW is the right choice for large residential systems and small commercial users who do not need storage capacities above 30-40 kWh. It is more compact (30 kg vs 47 kg), more economical, and sufficient for most domestic systems with roofs up to 30 kWp. The X3-ULT-15K, on the other hand, is dedicated to C&I installations with very high storage needs (up to 2.8 MWh) and advanced per-phase management.
Is the X3-HYBRID-15.0-D compatible with Triple Power T-BAT batteries?
Yes, the X3-Hybrid G4 is compatible with Solax high-voltage Triple Power T-BAT-SYS-HV batteries. Multiple 5.8 kWh modules can be connected in series to increase the total storage capacity, with the TBMS-MCS0800 acting as the master BMS for the battery system.
Does the X3-HYBRID-15.0-D support zero export control?
Yes, thanks to the included CT, the system monitors the grid connection point and modulates PV production and battery discharge in real time to keep export at the desired value (zero export or configured threshold).
Can I connect the X3-HYBRID-15.0-D to a system with an existing string inverter?
Yes, it is possible to install the X3-Hybrid G4 alongside an existing string inverter. In this case, the hybrid manages storage and EPS backup, while the string inverter continues to operate normally. The CT measures the overall flow at the grid connection point for the aggregated zero export function.
What is the role of the TBMS-MCS0800 in the system with the X3-HYBRID-15.0-D?
The TBMS-MCS0800 is the master BMS module that coordinates the operation of the HV battery modules connected to the X3-Hybrid G4. It manages communication between modules, balances charge/discharge cycles, monitors state of health (SOH), and ensures battery pack safety protections. It is a necessary component when installing 2 or more T-BAT HV modules.
