Y2-BAT | 2048Wh Expansion Battery
2048Wh power station expansion battery manufacturer for modular backup systems
Y2-BAT adds 2048Wh of LiFePO4 storage to compatible YAZO power stations without replacing the host unit's inverter and controls. The corrected compatibility matrix covers Y1, Y2, Y3 and R3 with up to 15 Y2-BAT packs, plus PPY-C2048H with up to 8 packs.
Corrected Compatibility Matrix
Match Y2-BAT to the host model before specifying pack quantity
Pack-count limits are model-specific and should be recorded in the quotation.
| Host Power Station | Verified Y2-BAT Limit | System Role |
|---|---|---|
| Y1 | Up to 15 packs | Adds stored energy to the Y1 2000W inverter platform |
| Y2 | Up to 15 packs | Adds stored energy to the Y2 2500W inverter platform |
| Y3 | Up to 15 packs | Extends runtime on the Y3 3600W platform |
| R3 | Up to 15 packs | Adds capacity to the R3 IP54 industrial platform |
| PPY-C2048H | Up to 8 packs | Expands energy storage on the C2048H backup platform |
Independent Recharging
Current Y2-BAT material shows AC, solar and vehicle recharge paths
The latest Y2-BAT charging graphic presents three ways to recharge the pack independently. These values are useful for project planning, but charging time should be treated as a reference rather than a guaranteed field result.
44V-56.5V
44V-56.5V input for connecting compatible expansion battery packs.
Up to 2100W
The source graphic shows about 1.1 hours under ideal sunlight.
12V / 24V
The source graphic shows a full-charge reference of about 12.5 hours.
For a bulk project, confirm the exact charging connector, input-voltage range and included cable set for the commercial SKU before publishing a fixed charging-time claim.
Battery Interface and Local Ports
The battery pack combines expansion connectivity with a local status and DC interface
The latest product imagery shows a front status display, USB connections and a covered DC interface. The reviewed fact table also lists a battery-pack interface range of 44–56.5V.
- Battery-pack interface reference: 44V–56.5V
- Front display for battery status information
- USB and DC interfaces are shown in current product imagery
- Host compatibility and expansion count remain the primary system-selection criteria
No AC inverter rating is assigned to Y2-BAT in the verified product matrix.
How Expanded Systems Are Used
More stored energy supports longer duty cycles across home, mobile and remote applications
Size energy capacity separately from inverter power
The application illustration represents typical demand categories. For AC appliances and tools, actual power capability comes from the connected host power station.
Extend operating time where recharge opportunities are limited
Use additional stored energy when the project needs longer runtime between charging windows rather than higher AC output.

Factory Verification
Expansion battery factory checks should verify capacity, charging and host-system compatibility
The Y2-BAT-specific QC image shows battery packs under electrical inspection. For wholesale production, release checks should follow the approved host model and expansion configuration.
- Confirm Y2-BAT identity and 2048Wh battery capacity
- Verify battery status display and available DC/USB interfaces
- Check applicable AC, solar and vehicle charging functions
- Match pack quantity to the approved host-model compatibility limit
- Confirm the included expansion cable and documentation
- Record any order-specific hardware or firmware requirements before shipment
Wholesale Expansion Battery Program
Wholesale Y2-BAT orders should identify the host power station before pack quantity is quoted
We supply Y2-BAT for distributors, replacement and upgrade programs, private-label projects and bulk energy-storage orders. The host model is the first technical field because Y2-BAT quantity limits differ between compatible systems.
Y1, Y2, Y3, R3 or PPY-C2048H
Identify the exact power station before selecting the number of expansion batteries.
15-pack or 8-pack limit
Use the corrected compatibility matrix rather than a universal maximum across all hosts.
AC, solar or vehicle recharge
Provide the planned charging source and any solar-array or vehicle requirements.
Quantity, branding and documents
Confirm order volume, logo, packaging, manual language, warranty wording and target delivery date.
