What is a UPS system and why is it important in the Cayman Islands?

A UPS (Uninterruptible Power Supply) provides immediate backup power when utility electricity fails. In the Cayman Islands, where power interruptions can be caused by storms, grid switching and generator transitions, a UPS protects computers, medical equipment, servers, security systems and network infrastructure from shutdowns, data loss and equipment damage.

How long will a UPS keep my equipment running?

UPS runtime depends on the connected load and battery capacity. Small office and home UPS systems may provide 5–30 minutes of runtime, while larger commercial and healthcare systems can be designed to run for hours when paired with external battery cabinets or standby generators.

Do I need a UPS if I already have a generator?

Yes. Generators typically take 10–60 seconds to start during a power outage. A UPS provides instant power during that gap, ensuring sensitive equipment like servers, POS systems, medical devices and security systems do not shut down while the generator starts.

How do I know what size UPS I need?

UPS sizing is based on the total electrical load (in watts or kVA), the type of equipment being protected, and the required runtime. Britthay performs professional UPS load assessments in the Cayman Islands to ensure systems are correctly sized for both performance and battery life.

How often do UPS batteries need to be replaced?

Most UPS batteries last between 3 and 5 years depending on temperature, usage and maintenance. In the Cayman Islands’ warm and humid climate, proactive battery testing and replacement is essential to ensure the UPS works when it is needed.

What types of buildings use UPS systems?

UPS systems are commonly used in offices, data centres, hospitals, clinics, banks, telecom rooms, retail POS systems, security and CCTV systems, and residential homes with sensitive electronics or remote working setups.

Uninterruptible Power Supply FAQs

A UPS (Uninterruptible Power Supply) is a backup power system that provides instant power during mains power interruptions and regulates incoming power to protect connected equipment from outages, surges, and voltage fluctuations. This helps prevent data loss, equipment damage, and operational downtime.
A UPS constantly conditions incoming electrical power and switches to battery backup the moment mains power fails. It supplies temporary electricity to your devices so they can continue running or shut down properly without interruption.
A surge protector only diverts voltage spikes. A UPS not only protects against surges but also conditions power and provides battery backup when mains power fails, ensuring continuous power to your equipment.
Modern standby generators are designed to be quiet and neighborhood-friendly. Most operate at sound levels similar to a central air-conditioning unit. Placement and enclosure options also help reduce noise, and our team ensures installations comply with local regulations.
Battery runtime depends on the load you connect to the UPS. Typical UPS systems provide 5–30 minutes of backup, enough to safely power down equipment or switch to a generator. For longer outages, UPS systems can be paired with external battery packs or standby generators.
Most standby generators in Cayman run on:

Natural gas

Propane (LP gas)

The best option depends on what fuel supply is available at your property. Gas-powered generators can run continuously without needing refueling, making them ideal for extended outages.
Add up the total wattage/VA of devices you intend to protect.

Choose a UPS with at least 20–25% more capacity than your estimated load to allow for device growth and to avoid overloading.
Yes, like any engine, generators need regular servicing to stay reliable. This includes:

Oil and filter changes

Battery testing

Software and control checks

Load testing

Britthay Electric offers scheduled maintenance plans to keep your system ready for hurricane season and unexpected outages.
UPS batteries typically last around 3–5 years under normal use. Routine testing and maintenance can help determine when a battery replacement is needed for optimal performance.
No, standby generators must be professionally installed. Installation requires:
