MILLY MALLY Kit de emergencia Sinus UPS-4000SR Inversor de onda sinusoidal pura 4000W con batería LiFePO4 100Ah 12V BMS

For homes, RVs, and off-grid setups that demand reliable backup power without the noise or fuel of a generator, this MILLY MALLY kit pairs a 4000W pure sine wave inverter with a 100Ah LiFePO4 battery. The integrated BMS and fast transfer time keep sensitive electronics safe during outages, while the built-in AC charger simplifies recharging.

Highlights

• 4000W continuous / 8000W peak pure sine wave output
• 100Ah 12V LiFePO4 battery with integrated BMS for longevity and safety
• UPS mode with <10 ms transfer time protects against power interruptions
• LCD display for real-time status monitoring
• Comprehensive protection: overload, short circuit, over-discharge, over-charge, over-temperature, reverse polarity
• Fan-cooled design with CE and RoHS certifications

In daily use

The pure sine wave output ensures compatibility with all AC devices, from motors and pumps to medical equipment and computers. The LiFePO4 battery offers over 2000 cycles at 80% depth of discharge, significantly outlasting lead-acid alternatives. The automatic transfer to battery power in under 10 milliseconds means your equipment never notices the switch. The integrated 20A AC charger replenishes the battery when grid power returns, making the system truly set-and-forget.
