Zero-break mission-critical power protection, high-efficiency online UPS, and intelligent battery systems
Voltage sags, utility blackouts, frequency fluctuations, and switching surges pose constant threats to critical healthcare equipment, data centres, banking networks, and automated manufacturing lines. Nairobi Power Engineers provides turnkey continuous power solutions engineered for absolute reliability.
From true online double-conversion three-phase UPS systems (10 kVA to 800 kVA) and modular battery energy storage banks to custom external maintenance bypass switchboards, we guarantee zero transfer interruption and conditioned sine-wave power 24/7.
Online Double-Conversion • 10 to 800 kVA
Three-phase online double-conversion UPS units featuring IGBT rectifier/inverter technology, unity power factor (kVA = kW), and up to 96.5% efficiency in double-conversion mode.
Battery Energy Storage • VRLA / Lithium
Heavy-duty 10-year design life VRLA AGM / Gel batteries and high-cycle Lithium Iron Phosphate (LiFePO4) rack-mounted energy storage systems with smart BMS.
Wrap-Around Bypass • Zero Break
Wall-mounted and free-standing switchboards with mechanical interlocked rotary changeover switches allowing safe live UPS isolation and maintenance.
Telemetry & BMS • SNMP / Modbus
Remote battery string impedance monitoring, real-time UPS telemetry, automated email/SMS failure alerts, and central BMS integration.
