Y3 | 3kWh-Class Expandable Home Backup
3600W home backup power station manufacturer for longer multi-load coverage
Y3 combines 3072Wh stored energy with 3600W rated AC output and 7000W surge capability. It is designed for buyers who need more operating reserve than a 2kWh-class unit while retaining 2100W solar input and compatibility with Y2-BAT expansion batteries.
Energy Reserve
3072Wh gives the backup plan more room before expansion is added
The 3072Wh base capacity is suited to buyers who need a broader mix of essential household, mobile and professional loads before moving to an external battery system. Runtime still depends on real wattage, duty cycle, conversion losses and starting state of charge.
Network and lighting loads
Prioritize long-running communication, routing and lighting loads before optional appliances.
Computers, refrigeration and media
Calculate simultaneous demand and account for compressor cycles where applicable.
Cooking and motor-driven equipment
Check continuous wattage and startup behavior separately against the 3600W and 7000W limits.
Application-image runtime figures are reference estimates. Use the buyer's actual connected-load list for a commercial configuration.
Regional AC Architecture
EU and US versions share 3600W output but use different bypass limits
Y3 keeps the same rated and surge output across its current EU and US versions. The important regional difference is bypass power: 3600W on the EU version and 2200W on the US version.
220–240V · 3600W rated · 3600W bypass
50/60Hz output with 7000W surge, 100W USB-C ports and 12V/30A Anderson output.
100–120V · 3600W rated · 2200W bypass
50/60Hz output with the same 7000W surge and direct DC/USB interface set.
| Field | EU Version | US Version |
|---|---|---|
| AC Output Voltage | 220–240V | 100–120V |
| Frequency | 50/60Hz | 50/60Hz |
| Rated AC Output | 3600W max | 3600W max |

| USB-A1 Output | 5V3A; 9V2A; 12V1.5A 18W Per Port | 5V3A; 9V2A; 12V1.5A 18W Per Port |
| USB-A2 Output | 5V2A | 5V2A |
| USB-C Output | 5V3A; 9V3A; 12V3A; 20V5A 100W Per Port | 5V3A; 9V3A; 12V3A; 20V5A 100W Per Port |
Regional Charging Throughput
EU charging reaches 2500W while the US input ceiling is 1800W
The Y3 charging system uses different AC ceilings by market but the same 2100W solar specification. When AC, solar and vehicle inputs are combined, total input must still remain within the regional maximum input limit shown for the ordered version.
220–240V · 13A max · 2500W max
Total combined AC + solar + car input must remain within the 2500W EU maximum input ceiling.
100–120V · 16A max · 1800W max
Total combined AC + solar + car input must remain within the 1800W US maximum input ceiling.
12–148V MPPT
18–140V operating range, up to 15A and 2100W maximum.
12–15V · 8A max
Lower-power charging path for compatible vehicle electrical systems.
Check Voc, Vmp and current
Confirm panel electrical values and connection hardware before approving the PV array.
Direct DC and USB Outputs
Reserve AC outlets for inverter loads and route compatible devices to DC
12V / 30A
High-current DC connection for compatible equipment and correctly rated cables.
12V / 10A · 120W total
Separate 12V output path for compatible vehicle and portable devices.
2 × 100W
Supports compatible laptops and mobile electronics through USB-C PD.
3 × 18W + 1 × 10W
Provides multiple lower-power USB ports for general accessories and mobile devices.
Expansion Strategy
Keep the 3600W inverter and add Y2-BAT when runtime is the limiting factor
Y3 is listed as compatible with Y2-BAT expansion batteries, with up to 15 packs. This lets system designers increase stored energy without changing the Y3 inverter platform.
3072Wh stored energy
Use the base unit when its energy reserve already meets the required backup duration.
2048Wh expansion battery
Add compatible expansion capacity when longer runtime is required.
Up to 15 packs
Confirm required cable and tested firmware or hardware details before releasing a multi-battery system.
Mobile Deployment
Built-in wheels help move a 37.8 kg 3kWh-class power station
Y3 is a heavier home-backup unit, but the enclosure incorporates wheels and a transport handle. That makes it more practical for moving between storage, a home backup position, a temporary work area or an outdoor deployment.
- Home and small-business backup
- Temporary office and media equipment
- Outdoor cooking and campsite power
- Professional equipment within the 3600W continuous limit
