Power continuity for the systems that must stay on

Start with the load and the autonomy

We list what must keep running during an outage and for how long: recorders and core switches, access controllers and locks, the control room, intercom. Autonomy is set by how long the generator takes to start and stabilise, or how long the site can be without mains if there is no generator.

Each part of the power chain has its own page with the detail:

Online double-conversion UPS units protect sensitive equipment from the poor power quality that is common at the end of long feeders. Battery life depends heavily on temperature: VRLA batteries are rated at 25 °C and their life falls sharply above that, roughly halving for every 8–10 °C of sustained increase. An UPS in an unventilated cupboard in a Riyadh summer will need new batteries far earlier than its datasheet suggests. Room ventilation or air-conditioning is part of the design.

Central battery systems and generators

Central battery systems (CBS) supply emergency lighting from one monitored battery source, designed to EN 50171 where specified, with automatic testing and logs. For generators we design the interface: automatic transfer switch (ATS) signals, load priority, and the test regime that proves the system starts under load.

Solar PV

We engineer, install and programme solar PV installations as a dedicated practice within our power continuity division. Every design starts from the site's load profile and available roof or ground area, sizing strings to the inverter's MPPT voltage window with cell-temperature derating. In Saudi Arabia, high module temperatures and dust accumulation directly impact output, so thermal coefficients and cleaning schedules are built into our yield calculations.

• On-grid systems reduce bills and need approval from the utility before connection. We prepare the technical package for that application.
• Hybrid systems add batteries to carry critical loads through outages.
• Off-grid systems power remote sites such as perimeter cameras, gatehouses and telecom points, where a cable run would cost more than the panels.

We provide design, installation and commissioning services. Panels, inverters and batteries are procured by you or your contractor against our specification.
