Solax X1-VAST-10K 10.0kW HV Single Phase Hybrid Inverter

  • 10kW high‑voltage single phase hybrid inverter for larger commercial and industrial solar‑plus‑storage systems.
  • Flexible expansion with dual battery ports, 2‑in‑1 function and microgrid / generator modes for complex site requirements.
  • High efficiency, IP66 enclosure and full protection set for reliable long‑term operation in demanding UK environments.

Brief description

The Solax X1‑VAST‑10K is the largest model in the single‑phase X1‑VAST hybrid inverter range, providing 10.0kW of AC power while managing both PV generation and high‑voltage battery storage. It combines grid‑connected, off‑grid and backup (EPS) operation in one unit, with dual battery inputs and intelligent control.

With 20000Wp maximum PV input, 4 MPPT trackers, 20A input per tracker and low PV start‑up voltage, it supports sizeable roof or ground‑mount arrays and makes effective use of available generation. Smart energy features, VPP readiness and V2G/V2H support make it suitable for modern commercial and industrial projects.

Key features

  • 10kW single phase hybrid inverter – Nominal AC output power 9999W and EPS off‑grid power 10000VA for larger single‑phase loads.
  • High‑voltage PV and battery system – 20000Wp max PV input, four MPPTs, dual battery ports and 2‑in‑1 function for scaling storage and generation.
  • Smart energy and VPP‑ready – V2G/V2H ready, with Smart Schedule, Scene and TOU management plus VPP interfaces (FCAS, IEEE 2030.5 and OpenADR).
  • Robust protection and fast EPS switching – 10s 200% EPS output, UPS‑level switch time (≤10ms), SPD Type II on DC and AC, optional AFCI and full electrical protections.
  • IP66 and natural convection cooling – Weather‑resistant housing and fanless cooling for quiet, low‑maintenance operation.

Where to use this inverter

X1‑VAST‑10K is designed for sites where single‑phase supply is available but power demand and PV capacity are relatively high. Typical applications include logistics depots, light industrial units, workshops and commercial buildings needing behind‑the‑meter solar storage, peak‑shaving or backup for critical loads.

Given its high‑voltage hybrid design and EPS capability, installation and commissioning must be carried out by qualified electricians familiar with Solax equipment and UK standards such as G99. Energian can help size systems and arrange installation via trusted UK partners.
