Performance & Features
-
Zero transfer time from AC to battery (i.e. no interruption)
-
Supports parallel redundancy (N+X) up to 4 units to increase capacity or reliability
-
Wide input voltage and frequency tolerance, making it robust for unstable grid or generator use
-
Built-in protections: overload, short circuit, over-temperature, low battery etc.
-
Efficient operation (~93.5% efficiency reported in some listings)

Warranty | 2 years for the UPS; battery warranty shorter (often 1 year) |
Pros & Considerations
Advantages
-
Very robust for mission-critical environments (data centres, hospitals, industrial automation) because it offers true online protection, zero transfer time, stable output even during grid disturbances.
-
High capacity (9 kW usable power) allows for large loads or overhead in load growth.
-
Scalable via parallel configurations — useful if you need redundancy or expansion.
-
Good compatibility with generators (because of wide voltage/frequency input ranges).
Things to Check / Be Careful About
-
Battery maintenance & replacement cost: SLA batteries degrade over time; full replacement can be expensive.
-
Heat & ventilation: since this UPS is large and handles high power, ensure good airflow / cooling.
-
Installation site: the size, weight, and infrastructure (floor strength, access) matters.
-
External battery packs if long runtimes needed, adding more cost, space, and maintenance.
-
Efficiency vs load: like many UPS systems, efficiency improves at higher loads; under-loading can reduce efficiency.
