SolaX X3-Ultra 30.0kW HV 3‑Phase Hybrid Inverter Key benefits 30kW three‑phase C&I hybrid inverter for larger commercial and industrial systems combining PV generation and high‑voltage lithium batteries. Supports up to 200% PV oversizing, 110% AC output and 200% EPS overload for 10 seconds, helping manage demanding site loads and short peaks. IP66‑rated, with Type II surge protection on AC and DC sides plus optional AFCI, suited to exposed plant rooms, rooftops and service yards. Brief description The SolaX X3‑Ultra 30.0kW HV 3‑Phase Hybrid Inverter is designed for three‑phase commercial and industrial projects that need a single platform for PV, battery storage and backup power. It offers smart management features including UPS‑level switchover, built‑in shadow tracking and smart load control, making it a practical choice for logistics hubs, small factories, retail sites and mixed‑use buildings. With support for up to 10 units in parallel and microgrid/generator functions, it can scale with project needs and integrate into wider energy strategies. Key features Three‑phase C&I hybrid inverter with 30kW rated output and EPS backup operation when paired with batteries. Max. 10 inverters in parallel for both on‑grid and off‑grid operation, plus microgrid and generator support for versatile system design. Max. 36A PV input per MPPT across three trackers, optimised for high‑power solar panels and flexible string layouts. Single‑unit UPS‑level switchover time below 10ms, with loads response time within 0.3s for smart loads such as heat pumps and EV chargers. VPP‑ready with compatibility options including OpenADR, IEEE2030.5, FCAS and API (feature to be upgraded in future firmware).

Any higher input DC voltage would probably damage inverter Note ② Input voltage exceeding the MPPT voltage range may triggers inverter protection Note ③ Compatible with a minimum of 3 units of HS Series batteries, but if the total voltage of the 3 batteries is less than 127V and there is no PV input, the system will not able to startup Note ④ When the voltage is below 180V, the inverter will limit the battery current to less than 20A Shipping Shipping is available to the UK, Ireland, Africa, the Caribbean and worldwide.
