Choose protection

What does a UPS actually protect against?

A UPS provides temporary battery power when the incoming supply fails. An online double-conversion UPS also conditions the supply to sensitive equipment during normal operation. The protection you need depends on the equipment and the disturbances at your site. Identify which systems cannot stop, whether they need time to shut down or must keep running, and whether a generator will take over. Powermode can assess these requirements before recommending the UPS and battery arrangement.

Single-phase or three-phase UPS?

Single-phase or three-phase selection depends on your available supply and the loads the UPS must support. The input and output configuration must suit the electrical installation; building size alone is not a reliable guide. Share your distribution-board information, equipment schedule and expansion plans with Powermode. The assessment should also consider how critical circuits are distributed, available installation space and whether redundancy is required. Confirm the proposed configuration before ordering equipment or changing circuits.

How is a UPS sized?

UPS sizing starts with the equipment that must remain powered and its real demand. The UPS must support both the required kW and kVA, with appropriate allowance for starting demand and planned growth. Battery runtime is a separate design requirement. Send Powermode an equipment list, measured loads where available, the supply configuration and the required backup duration. A site assessment helps confirm the recommendation rather than relying on a building size or a single nameplate rating.

Plan runtime

How much battery runtime do I need?

The right battery runtime is the time your operation needs to respond to a power failure. This might mean a controlled shutdown, bridging generator start-up, or keeping essential services running through a longer interruption. Start by listing the protected equipment and the duration each load must operate. Powermode can then match the battery bank to the measured demand and the UPS configuration. Allow for battery condition and the operating environment when reviewing a quoted runtime; it is not a fixed promise at every load.

Lithium-ion or lead-acid batteries?

Choose lithium-ion or lead-acid batteries according to the application, compatible equipment, operating conditions and lifetime cost. There is no universal best option for every installation. Ask Powermode to compare the purchase cost, expected replacement plan, available space, cycling requirements and service needs for your particular system. Battery voltage, charger settings and any required communication must suit the UPS or inverter. A change of chemistry should be assessed as a system modification, not treated as a simple like-for-like replacement.

Can battery capacity be expanded later?

Battery capacity can sometimes be expanded, but only within the limits of the equipment and the approved battery configuration. The original design should allow for the additional space, charging demand, protection and cabling. Before adding batteries, provide Powermode with the UPS model, existing battery details, installation date and required runtime. The team can check the proposed arrangement and whether replacement of the existing bank is more appropriate. Do not assume batteries of different ages or types can be combined.

Understand the site

Why conduct a power-quality assessment?

A power-quality assessment helps establish why equipment trips, resets or behaves inconsistently even when electricity is available. It considers the supply and the connected loads so the response addresses the observed problem. Tell Powermode when incidents happen, which equipment is affected and whether they coincide with switching or production activity. Existing alarm logs and maintenance records help define the investigation. The outcome should guide the choice of protection and electrical improvements rather than automatically assuming that a larger UPS will solve every issue.

Does every load need backup power?

Not every circuit needs backup power. Prioritising essential loads helps match the system to the business functions that must continue. List the equipment needed for safety, communications, transactions and core operations, then separate loads that can remain off during an outage. Powermode can assess the electrical distribution and the practical arrangements for those circuits. Share any loads that must start automatically and those that can be restored later so the installation supports an agreed operating plan.

Can UPS systems work with generators and solar?

UPS systems can form part of an installation that also includes a generator and solar equipment, provided the complete system is assessed for compatibility. Each device has a different role, and the connection and switching arrangements must be designed together. Provide Powermode with the existing equipment models, drawings and the loads to be protected. The review should cover how the site behaves when supply is lost and restored, how batteries recharge and how equipment is isolated for service. Solar generation alone does not establish guaranteed backup capability.

Keep it ready

How often should a UPS be serviced?

Plan UPS servicing around the manufacturer requirements, site conditions, operating duty and your agreed support contract. A system in a demanding environment may need a different inspection plan from one in a controlled equipment room. Powermode can review the installation, service history and battery condition to define the appropriate work. Power Guard membership includes an annual UPS service, with the contract setting out the included support. Report alarms or changed behaviour promptly rather than waiting for the next scheduled visit.

Can Powermode service another UPS brand?

Yes. Powermode provides servicing and maintenance across multiple UPS brands. The available work depends on the equipment model, condition, parts availability and the agreed scope. Send the make, model, rating, serial number, location and a description of the fault or service requirement when enquiring. Photos of the equipment identification label and any alarms can help the team prepare. If operational continuity is critical, discuss maintenance windows, bypass arrangements and an appropriate support agreement before work is scheduled.

What does remote monitoring add?

The Powermode Monitoring Portal (PMP) provides connected visibility of UPS status, alerts and uptime information to support maintenance decisions. It is designed to support all UPS brands, with the connection method and available data confirmed for the installation. Share the equipment models and network arrangements so Powermode can assess the required interfaces. Power Guard members can access an online monitoring dashboard where PMP is installed. Monitoring helps identify conditions requiring attention, while the agreed support contract defines incident handling and response.
