Powerful Performance to Meet All-Scenario Electricity Needs

As the central hub of household energy, this energy storage all-in-one system delivers outstanding performance. With a rated power of up to 22000VA/22000W and a surge power reaching 44000VA, it can easily handle the continuous operation of daily household appliances such as refrigerators, air conditioners, and washing machines, as well as the instantaneous startup of high-power electrical equipment, ensuring stable and uninterrupted power supply. The peak conversion efficiency of 93.5% means that every kilowatt-hour of photovoltaic power can be fully utilized, reducing energy loss and maximizing power generation benefits.

It offers flexible and diverse charging methods, supporting both photovoltaic charging and AC charging dual modes. The maximum photovoltaic power can reach 22000W, and combined with MPPT (Maximum Power Point Tracking) intelligent charging technology, it can accurately track the maximum power point of the solar panels. It efficiently captures solar energy within a wide DC voltage range of 120~450V, maintaining stable charging efficiency even when the light conditions change. With a maximum photovoltaic charging current of 100A and a maximum AC charging current of 60A, it enables fast energy replenishment, eliminating range anxiety. The 20kWh large-capacity battery pack adopts Grade A lithium iron phosphate cells, which have a long cycle life and high safety. It can meet the all-day electricity demand of families and help save electricity costs by switching usage between peak and off-peak electricity price periods.

The output end also performs excellently. It provides a standard 230VAC voltage output, supporting wide voltage adaptation of 170-280VAC (for computers) and 90-280VAC (for household appliances), and an adaptive frequency of 50Hz/60Hz. The pure sine wave output waveform is consistent with the quality of grid power, which can safely drive various precision electronic devices and household appliances. The fast switching time of 10ms (for computers) and 20ms (for household appliances) enables instantaneous and seamless connection in case of power outage, effectively protecting equipment data and operational safety.

Modular Design for Flexible Adaptation to Diverse Needs

This energy storage all-in-one system adopts an innovative stackable modular design, breaking the fixed form limitations of traditional energy storage equipment. A single battery module has dimensions of 560mm × 430mm × 150mm, and the overall machine size is 560mm × 430mm × 600mm. With a compact structure, it does not occupy much household space and can be flexibly placed in garages, storage rooms, and other areas. It supports parallel expansion of up to 6 units. As the household electricity demand grows or the photovoltaic system is upgraded, modules can be added at any time to expand power and capacity on demand without replacing the entire set of equipment, significantly reducing upgrade costs.

The internal structure of the equipment adopts a plug-and-play design, making installation and maintenance simple and convenient, which can be easily operated without professional technicians. Equipped with an intelligent LCD display, it real-time shows key data such as battery power, charging and discharging power, voltage, and temperature, allowing the equipment's operating status to be clearly visible. At the same time, it supports WiFi remote monitoring function. Through a mobile APP, users can check the equipment's operating status anytime and anywhere, remotely set charging and discharging parameters, and achieve intelligent management, saving time and effort.

Comprehensive Protection for Safe and Stable Operation

Safety is the core demand of household energy storage equipment. The SC DHF5500-48 is built with an advanced BMS (Battery Management System), which conducts 24/7 real-time monitoring of battery parameters such as voltage, current, and temperature. It is equipped with multiple protection functions including overcharge, over-discharge, over-temperature, over-current, and short circuit protection, comprehensively safeguarding the safety of the battery and equipment, and effectively extending the battery life.

The product has undergone rigorous environmental testing and can adapt to a wide operating temperature range of -10℃ to 50℃ and a storage temperature range of -15℃ to 60℃, ensuring stable operation regardless of severe cold or extreme heat. With a relative humidity adaptability of 5%~95%, there is no need to worry about equipment failure even in humid environments. Both the battery modules and the entire machine have passed strict quality inspections, featuring a robust structure that is shockproof and drop-resistant, ensuring long-term safe and reliable operation.

In addition, the equipment is equipped with RS232/RS485/CAN communication interfaces and dry contacts, which can seamlessly connect with photovoltaic inverters, smart home systems, and other equipment to build an integrated intelligent energy network, realizing more efficient energy dispatching and management.
