Practical power for real-life needs
Its real advantage is flexibility. The 1800W inverter remains the same, but extra P180-B modules extend runtime without replacing the main power station.
Why this model stands out
Capacity that grows with you
Each P180-B adds 1024Wh, with up to four supported.
Portable when used alone
The base station weighs 11.64kg, so you only carry the extra modules when needed.
Fast, flexible charging
Combined mains and solar input reaches up to 1500W, with 80% claimed in around 36 minutes.
Useful app control
Monitor power flow, battery state and outputs from your phone.
What that means in everyday use
Expandable home backup
Protect broadband and lighting first, then add enough storage for refrigeration and longer outages.
Variable-length trips
Take the capacity that matches the journey rather than moving the full system every time.
Solar storage
Capture more daytime generation for use after sunset.
Power and capacity answer different questions
Watts determine what can run at the same time; watt-hours describe the stored energy. A 100W device used for ten hours would consume 1000Wh in theory, before conversion losses and changing duty cycles are considered.
Allow for start-up surges as well. Fridges, pumps and power tools may briefly demand far more than their average draw. Sensible headroom prevents shutdowns and leaves capacity for a second device.
A strong choice if…
you want a manageable 1800W station today and a clear route to much longer runtime later.
Consider another model if…
you need more than 1800W continuous output. Expansion batteries add energy, not extra inverter power.
Real-world runtime examples
Approximate figures based on around 85% usable energy. Actual runtime depends on the appliance, efficiency and duty cycle.
What to check before you buy
Only the Pro model accepts P180-B batteries, which cannot operate independently. Allow suitable space and ventilation for a multi-battery installation.

Questions buyers often ask
How is it different from the P180?
The Pro accepts up to four P180-B expansion batteries.
How many batteries can I add?
Four, for 5120Wh total system capacity.
Can a P180-B work on its own?
No, it requires the P180 Pro.
Does expansion increase the 1800W output?
No, it only extends runtime.
Is the UPS suitable for a PC?
Sub-10ms switching works with many PCs and routers, but critical equipment should be tested with its actual power supply.
