The Intelligent Investment in Long-Term Energy Resilience

Power disruptions are expensive. Whether it’s a storm, grid failure, or unexpected demand spike, downtime risks financial loss, operational delays, and even safety hazards. The Pramac GA20000 3-Phase 20kVA LPG & Natural Gas Backup Generator isn’t just another standby unit, it’s a multi-year cost-saving power solution designed to outperform cheaper alternatives while slashing maintenance, fuel, and replacement expenses.

Built for real-world resilience, the Pramac GA20000 combines industrial-grade engineering with smart monitoring and fuel flexibility, ensuring your home or small business stays online without the hidden costs of compromise.

The Hidden Costs of a “Good Enough” Backup Generator

Most residential backup generators cut corners where it matters most:

  • Weaker engines that wear out faster, demanding frequent (and costly) repairs.
  • No fuel flexibility, locking you into expensive diesel or forcing inefficient single-fuel reliance.
  • Lack of remote monitoring, leaving you blind to performance issues until it’s too late.
  • Short warranties that shift risk back to you after just 2–3 years.

These compromises aren’t just inconvenient, they’re financially reckless. A generator that fails mid-outage or drains your budget in maintenance isn’t a backup. It’s a liability.

The Pramac GA20000 eliminates those risks with engineered durability, smart efficiency, and a 5-year manufacturer’s warranty, proving that the right investment today saves you thousands tomorrow.

Fuel Flexibility = Lower Long-Term Expenses

Dual-fuel capability (LPG or natural gas) means you’re never held hostage by volatile fuel prices. LPG is often cheaper than diesel, and natural gas provides a seamless transition if your supply is stable.

  • No need for separate storage tanks, tap into existing gas lines or portable LPG cylinders, reducing infrastructure costs.
  • Optimised combustion efficiency ensures every unit of fuel delivers maximum power, cutting waste.

Generac G-Force OHV Engine: Built to Outlast the Competition

  • OHV (Overhead Valve) design improves airflow and combustion, reducing wear and tear on critical components.
  • Air-cooled reliability means no expensive coolant systems or radiator maintenance, just dependable performance.
  • 3000 rpm operating speed ensures consistent power delivery without the strain of high-stress cycles.

Cheaper generators skimp on engines. The Pramac GA20000’s Generac G-Force OHV engine is designed for decades of service, not just the warranty period.

Wi-Fi Remote Monitoring: Predict Failures Before They Happen

  • Real-time diagnostics via the Pramac app let you track fuel levels, runtime, and system health from anywhere.
  • Alerts for low oil pressure, overheating, or irregular performance mean you can schedule maintenance before a breakdown occurs.
  • No more emergency call-out fees, catch issues early and avoid costly last-minute repairs.

Downtime is expensive. The Pramac GA20000’s smart monitoring turns reactive fixes into proactive savings.

Three-Phase Power for Balanced, Efficient Energy Use

  • Balanced load distribution prevents voltage drops that can damage sensitive electronics (TVs, computers, medical equipment).
  • Lower fuel consumption compared to single-phase alternatives, critical for long outages.
  • Compatibility with high-demand appliances (well pumps, refrigeration units, workshops) ensures full functionality when it matters most.

Ultra-Quiet & Compact: No Compromises on Comfort or Space

  • 67dBA @ 7m is quieter than a normal conversation. No neighbour complaints or noise restrictions.
  • Compact canopy fits easily in gardens and yards and is designed to be installed outside due to extreme weather resistance.
  • Low vibration design reduces structural stress and extends the generator’s lifespan.

5-Year Manufacturer’s Warranty: Risk-Free Assurance

  • 5 years of coverage
  • No hidden clauses, just straightforward protection against manufacturing defects.
  • Peace of mind that your investment is safeguarded.

When will I receive my order?

In most cases, a product on our website will give you an indication of the current stock availability, but shipping is not uniform for all products. We maintain fantastic relationships with all of our suppliers and we aim to get products to customers within 3 business days of the order being taken. This availability is based on information from our suppliers and from sales and supply patterns. The availability information given is a guide only and not a guarantee as there are external factors that we may not have control over.

Coronavirus Update – UK couriers and transport companies will not currently guarantee delivery times and we are seeing a slight delay in deliveries – please bear this in mind when ordering.

Specialist Couriers – Some items such as the larger portable power stations are sent by specialist courier as standard couriers will not accept them. These specialist couriers are very reliable but sometimes don’t have tracking or timed delivery.

Split deliveries – We sometimes need to send orders for more than one item by different courier networks (portable power stations for example) – so you may receive items at different times.

1500rpm machines or larger diesel gensets however are typically priced on application and all depend on the destination. We will be happy to quote on any large diesel generator and discuss your needs over the phone or via email.

Most orders placed before 12pm on a business day will be shipped from our suppliers on the same day provided the product is in stock. If you need to be certain an item is in stock and available, or if you need a lead time, it’s worth calling our sales team on 01329 722390. Pricing for extended shipping areas like Northern Ireland, the Scottish Highlands and outlying Islands, Outer Hebrides, Channel Islands, Isle of Man, Scilly Isles, and other postcodes not considered as UK mainland are calculated at the checkout or can be obtained by calling our offices.

Please note that the processing of a payment and acknowledgement email does not constitute a legally binding contract. In the case of mispricing, changes in stock quantity, or if we believe the machine will be misused, we reserve the right to cancel the order and provide a full refund.

Heavy Items

You will be contacted by phone after ordering a larger item to confirm a delivery date before your order is dispatched. Large or heavy items are dispatched through a pallet network, so if we can’t get in contact with you, we may be unable to send out your item on a next day delivery. Please be sure to include a working phone number with your order.

Heavy items will require the recipient to make arrangements to take delivery of the goods and may require the recipient to help the courier unload the item. For items that are delivered on a pallet the courier will leave the pallet as close to your door as possible.

1500rpm diesel generators will require forklift (or similar) offloading; if this is not available then we can arrange a Hiab offload at an additional price – please call us to discuss any delivery requirements.
