Solar Charging, Fast Backup Transfer and Pure Sine Wave Power
The product series combines model-specific MPPT solar input, grid charging and AC output inside one floor-standing residential energy-storage system.
3–9kW Compatible PV Input
The 2kW models support up to 3kW PV input, the 3kW model supports up to 5kW, and the 5kW models support up to 9kW.
Specified Transfer Time Below 20ms
The documented transfer value applies to compatible connected loads operating within the selected system's power limits.
230Vac Pure Sine Wave
Choose 2kW, 3kW or 5kW output at 50Hz or 60Hz according to continuous-load and startup-power requirements.

How the Floor-Standing All-In-One Home ESS Works
Compatible PV strings connect through the integrated MPPT input, while the grid or another properly configured AC source connects through the AC input. The internal battery stores energy and the integrated inverter supplies selected household loads through 230Vac pure sine wave output.
One Integrated Energy Path from Solar and Grid to Household Loads
The system combines the main input, storage and output functions inside one enclosure while keeping each electrical limit visible for engineering selection.
Compact Floor-Standing Integration for Residential Energy Storage
The product family combines battery and inverter functions in a compact enclosure, with dimensions and weight varying by power and battery configuration.
2kW to 5kW
Three AC output levels for selected household and small-site loads.
2.6kWh to 8kWh
Five battery and inverter combinations across the product family.
About 20–60kg
Product weight varies according to battery energy, enclosure and output-power configuration.
RS485 / WiFi
Communication interfaces are listed across all five source configurations.
RS485 and WiFi Communication
All five product documents list RS485 and WiFi communication. These interfaces support compatible system monitoring and communication integration according to the final project configuration.
Installation and Load Matching
Floor-standing integration reduces the visual number of separately installed energy-storage components, but the final installation still requires suitable electrical protection, cable sizing, ventilation, PV-string matching and load verification.
Applications for AINEGY Floor-Standing All-In-One Home ESS
The product series is designed for residential solar storage and selected backup loads that remain within the configured 2kW, 3kW or 5kW AC output.

Selected Household Loads
Configure priority loads according to continuous power, startup demand and required backup duration.
Residential PV Energy Storage
Match compatible PV strings to the model-specific maximum voltage, MPPT range and input-current limit.
Mountainous, Island and Remote Sites
Combine compatible PV and AC sources with integrated battery storage for selected residential loads.
Configured Household Appliances
Appliance input power and startup demand must remain within the selected 2kW, 3kW or 5kW system limits.
Selected Tools and Auxiliary Loads
Verify motor and tool startup power before connecting workshop or garage equipment.
Small Shops and Supermarkets
Use the system for compatible lighting, communication and selected equipment loads within the configured power range.
How to Choose the Right Output Power and Battery Energy
AC output power determines how much load can operate at one time. Battery energy influences how long the selected loads can be supported.
Calculate Continuous Load
Add the power of appliances expected to operate at the same time and keep the total within the selected output rating.
Check Startup Power
Motors, compressors, pumps and some appliances can require higher startup power than their normal running power.
Select Battery Energy
Compare expected energy consumption, required backup duration, available PV production and operating reserve.

Technical answers for homeowners, installers, distributors and project teams comparing the five AINEGY configurations.
The product integrates a LiFePO4 battery, inverter, PV charging, AC charging, pure sine wave AC output, UPS transfer functionality and RS485/WiFi communication inside one enclosure.
The series includes 2kW/2.6kWh, 2kW/4kWh, 3kW/5.2kWh, 5kW/5.2kWh and 5kW/8kWh configurations.
kW is the AC output-power rating available to connected loads. kWh is the battery-energy capacity used to store energy for later use.
Choose output power according to the total continuous load and the startup demand of appliances expected to operate at the same time.
Choose battery energy according to expected energy consumption, required backup duration, available solar generation and the desired operating reserve.
It is the specified transfer time of the integrated UPS function. Compatibility still depends on the connected equipment and the configured load.
Compatible PV strings must remain within the selected model's maximum PV voltage, MPPT voltage range and maximum input-current limit.
Yes. The product documents list integrated AC charging with a rated AC input voltage of 230Vac.
The source system diagrams show a diesel generator as an AC source. Generator voltage, frequency, waveform, power and control requirements must be matched for the project.
The system supports selected loads within the configured 2kW, 3kW or 5kW output rating. Whole-home suitability depends on the actual load profile and installation design.
Compressors, pumps, refrigerators, motors, power tools and some kitchen appliances can require startup power above their normal running value.
The product documents list RS485 and WiFi communication. Final monitoring functions and communication compatibility should be confirmed for the selected configuration.
