SolaX X3-Hybrid G4 PRO 12.0kW HV 3‑Phase Hybrid Inverter 12kW three‑phase high‑voltage hybrid inverter for larger commercial and industrial solar‑plus‑storage systems. Three MPPTs, dual battery ports and microgrid / generator modes for flexible design and robust backup. High efficiency, IP66 protection and comprehensive safety features for long‑term use on UK sites. Brief description The SolaX X3‑Hybrid G4 PRO 12.0kW is a three‑phase residential and light commercial hybrid inverter designed to manage PV generation and high‑voltage lithium battery storage on one platform. It offers 12kW rated output, a wide MPPT range of 110–950V and 20A DC input per MPPT, supporting modern high‑current modules and complex roof layouts. Dual battery ports with a 2‑in‑1 function allow flexible battery expansion and higher charge / discharge currents, while microgrid and generator modes enable more advanced backup and islanded operation. Smart scheduling, time‑of‑use control and VPP readiness support intelligent energy management on UK commercial and industrial projects. Key features 12kW three‑phase hybrid inverter – Rated output apparent power 12000W and 12kVA EPS capability, suitable for larger three‑phase loads. Flexible PV design – 24kWp recommended array power, three MPPTs, 20A per tracker and an ultra‑wide 110–950V MPPT range with 200% PV oversizing. Dual battery ports – Two HV battery ports with up to 50A total charge / discharge current using a 2‑in‑1 splitter cable, supporting sizeable battery banks. Strong backup performance – Up to 200% EPS output for 10s, three‑phase EPS at 230 / 400V and UPS‑level switchover time of less than 10ms. Smart management and protection – V2X‑ready, VPP‑ready, Type II SPD on AC and DC, optional AFCI and optional Rapid Shutdown, all in an IP66 enclosure. Where to use this inverter X3‑Hybrid G4 PRO 12.0kW suits three‑phase sites needing a high‑power hybrid inverter with battery storage, such as logistics depots, workshops, light‑industrial units and larger commercial buildings. It is appropriate for behind‑the‑meter solar storage systems, peak‑shaving, backup for critical loads and microgrid applications where generator integration or complex load profiles are involved. As a high‑voltage hybrid inverter with three‑phase EPS and advanced modes, installation and commissioning must be carried out by qualified electricians familiar with SolaX equipment and UK grid codes (e.g. G99). Energian can help design complete systems and arrange installation via trusted UK partners. Technical specifications PV input Max. recommended PV array power: 24kWp (X3‑HYB‑12.0‑P). Max.
