Pure sine wave + powerful, compatible with all household appliances: the inverter has a rated output power of 6000 W and a peak power of up to 12 kVA. Thanks to pure sine wave and low distortion, it is ideal for various household appliances such as refrigerators, air conditioners, computers and washing machines. It works silently and protects your devices, extending their service life. Robust Overload Protection: Equipped with over-current protection (160A when charging and discharging), it easily handles high performance requirements for a short time. The switching time is only 20ms (generator mode) or 10ms (UPS mode), preventing power outages.
Multilingual instruction manual: The product packaging comes with a printed English instruction manual that accurately describes the most important product parameters and operating steps. Do you need the user manual in other languages? Please contact us via the Amazon backend and we will send it to you as soon as possible.
Intelligent LCD touch screen + convenient operation, status display at a glance: Equipped with a high-resolution LCD touch screen, the device displays important real-time data such as photovoltaic input power, power connection, battery charge status (SOC) and load performance. The energy flow is visualised, and the colours change depending on the load (green → red). It supports customizable system parameters (including battery type, charging voltage, operating mode, etc.) for easy and intuitive operation. Integrated acoustic alarm function, clear error/warning codes and convenient maintenance are also available.
Highly efficient MPPT charging + multi-mode power supply for maximum energy utilisation: the integrated, highly efficient MPPT solar charge controller with a maximum PV input power of 9000 W, a tracking voltage range of 60-450 V DC and a tracking efficiency of up to 99.9% captures solar energy. It supports various power supply modes such as solar priority, mains complementarity and battery backup (SBU) for flexible switching. The output voltage is adjustable with adaptive frequency and perfectly compatible with European mains standards. So you can achieve energy self-sufficiency and reduce your electricity costs.
Extremely high capacity + extremely long service life, stable power supply without voltage spikes: Equipped with a 16.07 kWh LiFePO4 lithium iron phosphate battery with high capacity (51.2 V/314 Ah) and a standard discharge capacity of ≥ 314 Ah, this battery covers the entire power requirements of a household for daily use and as an emergency power supply. After 8000 charge-discharge cycles at 25°C and a discharge rate of 0.5C, it still retains 70% of its capacity. With an internal resistance of ≤ 13.9 mΩ, it significantly exceeds the life of conventional batteries. A one-time investment with long-term benefits – no more annoying battery replacement.
Equipped with WiFi module and intelligent COM/BMS interfaces: thanks to the included WiFi stick, data can be monitored via app. By plugging into the intelligent COM interface, data exchange between the battery system and the cloud platform is possible. The BMS interface connects the system to the battery management system (BMS) for monitoring battery status, control and communication.
