Single-phase hybrid grid home ESS is one of the batteries in the all-in-one inverter and battery series. It is currently available in two specifications: 10 kWh and 20 kWh.
It features a plug-and-play, stackable design, allowing for quick adjustment in 10 minutes, saving time, space, and costs, making it convenient and easy to use. It boasts a high photovoltaic power acceptance rate, accepting 40~600Vdc current and 2 times the rated power input. In terms of safety, it features automatic safety protection and an AFCI automatic arc fault circuit interrupter. It supports diverse combinations with flexible options, including 2*10.24 kWh battery modules + optional battery packs.
Features and Function
Safety Protection
The all-in-one single-phase hybrid grid home ESS integrates multiple protection functions, including short-circuit protection, ground insulation resistance monitoring, leakage protection, anti-islanding protection, and DC over-voltage and over-current protection.
The product is equipped with a ground fault alarm system. When there is poor grounding or no grounding on the AC side, the device will emit an audible alarm, and the LED indicator will light up red.
Energy Conversion and Management
The all-in-one single-phase hybrid grid home ESS efficiently converts direct current (DC) generated by photovoltaic arrays or batteries into alternating current (AC) that meets grid specifications. Additionally, it facilitates the transfer of DC power from solar panels to batteries.
The product features a built-in bidirectional converter that enables both charging and discharging of the battery, ensuring optimal energy utilization. To maximize the power output of photovoltaic strings (which may have different orientations, tilt angles, or module configurations), the energy storage system (ESS) employs multiple maximum power point (MPP) trackers. These trackers allow the ESS to extract the maximum available power from each photovoltaic string, thereby improving overall system efficiency.
Power Derating
This all-in-one single-phase hybrid grid home ESS features a power derating function, a protective measure used to prevent the energy storage system from overloading or malfunctioning. Furthermore, the derating function can be activated according to grid requirements.
The product can activate Demand Response Mode (DRM) by connecting to a Demand Response Enabling Device (DRED). Once triggered, the ESS will quickly detect and respond to all supported demand response commands within 2 seconds.
Normal Operating Voltage Range
The all-in-one single-phase hybrid grid home ESS is designed to operate effectively within the specified voltage range for the given observation period.
If the voltage level deviates from the specified operating level, the energy storage system will disconnect from the grid within the protection time. If a transient disturbance occurs that is shorter than the required protection time, the energy storage system can automatically reconnect to the grid once the disturbance subsides and the voltage level returns to the normal operating level.
Normal Operating Frequency Range
This all-in-one single-phase hybrid grid home ESS is designed to operate within the specified frequency range for at least a certain period of time.
If the frequency falls outside the defined operating range, the energy storage system will disconnect from the grid. If a temporary disturbance occurs that lasts for a shorter duration than the required protection time, the energy storage system will automatically reconnect to the grid once the frequency returns to normal operating levels after the disturbance subsides.
Reactive Power Regulation
This all-in-one single-phase hybrid grid home ESS provides reactive power regulation modes to support grid operation. The specific reactive power regulation modes can be configured and adjusted via the App.
Communication and Configuration
This all-in-one single-phase hybrid grid home ESS supports RS485, Ethernet, WLAN, and CAN ports for device and system monitoring. These ports allow for parameter configuration to achieve optimal operation.
Emergency Charging Management
This all-in-one single-phase hybrid grid home ESS features EPS charging management functionality. This function is designed to protect the battery from damage caused by prolonged over-discharge. During emergency charging, the ESS will not respond to discharge commands.

Product Storage
Batteries stored for extended periods (unused for more than 3 months) must be kept in a dry, cool place. They should be stored at a temperature of 23±2℃ and a humidity of 45%-75%. Batteries left unused for extended periods should be recharged every three months to ensure the battery voltage remains within the normal range.
