A 350kVA generator delivers substantial power output for large-scale commercial operations, industrial facilities, hospitals, data centres, manufacturing plants, and major construction projects. These heavy-duty diesel sets provide reliable performance for both mission-critical standby backup and continuous prime power applications. At Generator Warehouse, we stock premium 350kVA models from industry-leading manufacturers including Cummins, Perkins, and FG Wilson.
Our 350kVA diesel generators are available in both soundproofed canopy enclosures for urban installations and noise-sensitive environments, and open-frame configurations for industrial sites where acoustic performance isn’t a priority. Each unit can be specified with automatic transfer switching, synchronisation for parallel operation, remote monitoring, and comprehensive load management systems.
Built to deliver consistent performance under demanding conditions, 350kVA generators are commonly deployed in healthcare facilities requiring uninterrupted power, manufacturing operations that can’t afford downtime, large commercial properties needing business continuity protection, and construction sites requiring robust temporary power. They offer excellent fuel efficiency, low emissions, and straightforward maintenance requirements for both standby and continuous operation.
At Generator Warehouse, we provide complete project support including expert technical specification, competitive pricing, nationwide delivery and installation, commissioning services, and ongoing maintenance support. Our experienced team will assess your load requirements, runtime needs, and site conditions to recommend the most suitable 350kVA diesel generator for your specific application.
Whether you need emergency backup power or prime power generation, our 350kVA range delivers the reliability and performance your operation demands.
Is a 350 kVA generator suitable for hospitals?
Yes, a 350 kVA generator is ideal for hospitals and other healthcare facilities, where uninterrupted power is crucial for patient care. It can power life support systems, surgical equipment, lighting, and essential HVAC systems, ensuring that critical services remain operational during a power outage. Hospitals often use multiple generators in parallel to provide redundancy and ensure that power is always available, even if one generator fails. Smaller clinics may find a 200kVA or 250kVA generator sufficient, while larger hospitals typically require 500kVA or 800kVA generators.
What is the noise level of a 350 kVA generator?
The noise level of a 350 kVA generator typically ranges from 75 to 85 decibels, depending on whether it is enclosed or located in an open space. For comparison, this is similar to the noise of a busy urban street. In sensitive environments like hospitals, additional soundproofing measures, such as acoustic enclosures or barriers, are often used to reduce noise levels and create a quieter environment for patients and staff. Silent canopy options are available across our range, from compact 30kVA generators through to 600kVA and 900kVA units.
How many kW is a 350 kVA generator?
At a typical 0.8 power factor, a 350 kVA generator provides about 280 kW of prime power. Standby power is commonly around 308 kW, but the exact rating should be checked on the chosen model’s datasheet.
How many amps does a 350 kVA generator supply?
At 400V three phase, a 350 kVA generator supplies about 505 amps per phase. This is a guide only: a qualified electrician should confirm cable, switchgear and protection sizes for the installation.
How much fuel does a 350 kVA generator use per hour?
A diesel generator of this size typically uses about 38 to 70 litres an hour, depending on load. Treat this as a planning range rather than a model-specific figure and check the selected generator’s fuel-consumption curve for an exact estimate.
How much does a 350 kVA generator cost?
Indicative new prices are commonly around £34,000 to £50,000 ex VAT. Engine and alternator brand, acoustic canopy, control panel, fuel tank, delivery, commissioning and installation can all change the final quote.
What can a 350 kVA generator power?
This size is commonly used for large construction sites, warehousing, cold storage, healthcare facilities, data centres and industrial backup. The right choice still depends on the total running load and the starting current of the largest motors or equipment.
