About Our Power Backup Systems Service

Kenya’s power supply, while improving, remains subject to outages, load shedding, and voltage fluctuations that can disrupt homes, businesses, and critical operations. Andrex Electricals Systems designs, supplies, and installs complete power backup solutions tailored to your specific load requirements and budget. Whether you need a small inverter to keep your lights and Wi-Fi running during an outage, a high-capacity solar-battery hybrid system for energy independence, or a diesel generator to power an entire facility, our team has the expertise to deliver a system that works reliably when you need it most.

Inverter & Battery Backup Systems

For most residential and small commercial applications, an inverter with a battery bank is the most cost-effective and low-maintenance backup solution. We supply and install inverter systems ranging from small 1kVA units suitable for a few lights and a router, up to large 10kVA+ systems capable of powering an entire home or office during a grid outage. We work with reputable inverter brands and use quality lithium or deep-cycle lead-acid battery banks, sized correctly for your required runtime. All systems are wired with proper changeover switching, fusing, and cable sizing to ensure safe and reliable automatic switchover when the grid power fails.

Generator Installation & Commissioning

For applications where longer runtimes, heavier loads, or full facility backup is required, a diesel or petrol generator is often the most appropriate solution. We supply generators from trusted manufacturers, handle all civil works coordination for generator bases and enclosures, and carry out the complete electrical installation including cabling, automatic transfer switches (ATS), and integration with your existing distribution board. An ATS system detects a grid power failure and automatically starts the generator and transfers the load within seconds — with no manual intervention required. We commission every generator installation with a full load test to verify correct operation before handover.

Solar Panel & Battery Storage Systems

Solar power, combined with modern lithium battery storage, is transforming the way Kenyan homes and businesses manage their energy. We design and install grid-tied, off-grid, and hybrid solar systems, taking into account your daily energy consumption, available roof space, and budget to recommend the most cost-effective configuration. Hybrid systems are particularly popular — they use solar energy during the day to charge a battery bank and power your loads, draw from the battery at night, and only fall back to the grid or generator when the battery is depleted. Over time, a well-designed solar system significantly reduces electricity bills while providing reliable backup during outages.

UPS Systems for Critical Equipment

For offices, server rooms, medical facilities, and data centers, an uninterruptible power supply (UPS) provides instant, seamless protection for sensitive electronic equipment against power outages, voltage sags, surges, and interference. Unlike a generator or inverter — which take seconds to switch over — a UPS provides instantaneous power continuity, protecting computers, servers, and critical systems from data loss and hardware damage. We supply and install UPS systems from reputable manufacturers, size the UPS correctly for the connected load and required runtime, and carry out periodic battery capacity testing to ensure the system will perform when needed.
