Why this model deserves a closer look
Designed exclusively for the P310 Power Station, the P310-B expansion battery increases your total energy storage with a simple plug-and-play setup. You can connect up to 2 expansion batteries to one P310 main unit for extended runtime at home, outdoors, or during power outages.⚠️ Not compatible with other models. P310 main unit required.
How to decide using the right criteria
Start by listing the genuinely essential devices, their continuous draw and any start-up surge. Watts describe simultaneous output; watt-hours or kilowatt-hours mainly determine how long that output can be sustained.
Maximum solar input is not guaranteed production. Panel orientation, weather, temperature, conversion losses and the permitted voltage range all affect the result. Check the cables and connectors included with the exact bundle as well.

Frequently asked questions
Does compatibility need to be checked?
Yes. Check the reference, connectors, voltages and limits published by AFERIY before ordering.
Why is no fixed price shown?
Mon Choix explains the decision criteria without freezing a changing price. The button will lead to the exact offer and its current price.
How can useful runtime be estimated?
Add the consumption of essential devices, estimate their operating time and allow for conversion losses. Real loads and operating conditions will change the result.
Is maximum solar input always achieved?
No. It is an input limit. Real production depends on the panels, wiring, sunlight, orientation and temperature.
Can an extra battery be added later?
Only when AFERIY confirms the exact model, cable and module-count compatibility. Expandable does not mean every battery is interchangeable.
