Absolute reliability and clean energy: Stark Country introduces the flagship 5000 ONLINE LFP UPS

Stark Country expands its range of professional solutions for guaranteed energy supply and announces the launch of a new model, the Stark Country 5000 ONLINE LFP (60A). It is a multifunctional device of the "Inverter + On-Line UPS" class, combining dual voltage conversion technology, support for modern lithium storage devices and an integrated MPPT controller for solar panels.

This new product is engineered to protect critical equipment in private residences, commercial facilities, IT infrastructure, and light industrial plants where even millisecond power sags are unacceptable.

Key Advantages

• Zero Transfer Time (0 ms) and Pure Sine Wave: Thanks to double-conversion (Online) topology, transfer to battery power occurs with zero sine wave interruption (0 ms), guaranteeing safe operation for highly sensitive electronics, gas boilers, server infrastructure, and medical equipment.
• Lossless Energy: Output power factor is 1.0 (unity)—delivering a true rated capacity of 5,000 VA / 5,000 W.
• Compatibility with Modern LFP Batteries: The unit is optimized for lithium iron phosphate (LiFePO4) battery systems, including proprietary Stark SLH 51.2-100 19" and SLW 51.2-100 modules. An integrated BMS communication interface and an intelligent 3-stage charger with mains charging current up to 60 A ensure gentle, high-speed charging. Full backward compatibility with AGM and GEL batteries up to 1,200 Ah is also preserved.
• High Overload Capability: The UPS easily handles inductive inrush currents—tolerating overloads up to 150% for 10 seconds and up to 200% for up to 5 seconds.
• Integrated Solar Generation Support: A built-in 4,000 W MPPT charge controller easily turns the UPS into a comprehensive hybrid power system running on solar PV modules.
• Scalability up to 45 kW: A factory-installed parallel connection board allows combining up to 9 units either for single-phase capacity expansion or for configuring a complete three-phase system (380 V).
• User-Friendly Management: Standard equipment includes an integrated Wi-Fi module for remote monitoring, a USB On-The-Go port for fast configuration cloning and log export to USB flash drives, and support for optional SNMP cards.
