Overlooking Countless Small Mountains (Xiamen) Electric Power Technology Co., Ltd. is one of the leading manufacturers and suppliers of 2000w expandable home backup power station in China. We have world-leading production equipment and strong manufacturing capabilities. Welcome to wholesale bulk premium 2000w expandable home backup power station from our factory.
Y1 | Expandable Home Backup Power
2000W home backup power station manufacturer with Y2-BAT expansion
Y1 starts with a 1024Wh LiFePO4 battery and 2000W rated AC output, then adds a feature that changes how buyers can plan future backup capacity: compatibility with Y2-BAT expansion batteries. Current Y1 product media also lists 4500W surge power, 1400W AC charging, 800W solar input and 100W USB-C output.
Expandable Architecture
Start at 1024Wh and keep an expansion path open
Y1 is positioned differently from fixed-capacity 1kWh power stations because it supports the Y2-BAT expansion platform. Up to 15 Y2-BAT packs are specified for Y1; connection hardware and system-version requirements should be confirmed for the final project configuration.
Y1 provides the inverter, controls and first 1024Wh
Use the Y1 base unit when the project needs a 2000W AC platform with a compact initial battery. Add expansion only when the procurement brief requires more stored energy.
- 1024Wh LiFePO4 battery in the main power station
- 2000W rated AC output remains the continuous inverter limit
- Y2-BAT compatibility creates a separate capacity-expansion path
- Up to 15 Y2-BAT packs are listed as compatible with Y1
Expansion-battery capacity listed for the compatible Y2-BAT model.
Maximum Y2-BAT pack count specified for the Y1 expansion platform.
Confirm the required cable and applicable firmware or hardware version before a multi-battery project is released.
Battery and Load Profile
1024Wh LiFePO4 battery for prioritized backup loads
The Y1 battery is specified at 1024Wh with LiFePO4 chemistry and a 3500+ cycle reference. Actual backup time depends on device draw, conversion losses, duty cycle and starting state of charge.
Keep connectivity loads prioritized
Routers, communication devices and low-power lighting can be separated from larger appliance loads when planning outage coverage.
Check compressor startup demand
Use both running wattage and startup power when evaluating refrigerators or other compressor-based equipment.
Build a small-office backup list
Calculate the combined draw of computers, monitors, networking hardware and other required peripherals.
Verify transfer and runtime requirements
For sensitive equipment, confirm power quality, transfer behavior and the device manufacturer's backup-power requirements before use.
Regional AC Versions
One 2000W platform with separate EU and US output configurations
Y1 is supplied in market-specific AC versions. The EU configuration uses 220–240V output, while the US version uses 100–120V. Both list 2000W rated output, 4500W surge power and 2000W bypass mode.
220–240V AC · 50/60Hz
2000W rated output, 4500W surge, 2000W bypass, 100W USB-C and 12V/10A DC output.
100–120V AC · 50/60Hz
2000W rated output, 4500W surge, 2000W bypass, 100W USB-C and 12V/10A DC output.
| Field | EU Version | US Version |
|---|---|---|
| AC Output Voltage | 220–240V | 100–120V |
| Frequency | 50/60Hz | 50/60Hz |
| Rated AC Output | 2000W | 2000W |
| Surge Output | 4500W | 4500W |
| Bypass Mode | 2000W | 2000W |
| USB-C | Up to 100W per listed port | Up to 100W per listed port |
Three Recharge Paths
1400W AC charging, 800W solar input and vehicle charging
The charging architecture supports fast mains recovery at home, high-power solar input for off-grid use and lower-power vehicle charging when the system is in transit.
- US AC input: 90–140V, 50/60Hz, up to 12A and 1400W
- EU AC input: 190–250V, 50/60Hz, up to 6.5A and 1400W
- Solar input: 12–78V MPPT
- PV operating range: 18–75V, up to 14A and 800W
- Vehicle input: 12–15V, up to 8A
Portable Use Beyond the House
The expandable home-backup platform can also travel
At 12.6 kg, Y1 remains transportable enough for temporary outdoor use. The same 2000W inverter and 1024Wh base battery can support compatible campsite electronics, photography equipment and mobile work devices when the load stays within the product limits.
Use the base 1024Wh pack for portable loads
Plan appliances from simultaneous wattage and expected operating time, then choose AC, solar or vehicle charging for the trip.
Choose expansion and the fuller cable set over higher USB-C wattage
Y1 Lite provides higher 140W USB-C output, but standard Y1 is the better fit when the project specifically requires Y2-BAT expansion compatibility and the included MC4-to-Anderson charging cable.

Provide simultaneous running loads, startup demand and required backup duration.
Base-only or Y2-BAT system
State whether expansion batteries are required now and the planned number of compatible packs.
EU or US electrical configuration
Provide destination country, output voltage, frequency and required AC socket standard.
Quantity, branding and documents
Confirm order quantity, logo, packaging, manual language, required documents and target delivery date.
