Description
The Anker SOLIX BP5000 expansion battery adds a further 5,024 Wh of storage capacity to your existing Anker SOLIX Solarbank system. That lets you store more solar power and use a larger share of it yourself in the evening instead of exporting it to the grid.
The battery uses long-life LiFePO4 cells and is built for a long service life. It has no inverter of its own – it adds to an existing main unit purely as storage.
Highlights & benefits
- Substantial extra capacity: 5,024 Wh (314 Ah) noticeably expands your system and extends the window in which you're running on your own solar power.
- Long-life LiFePO4 cells: designed for around 15 years of product life and backed by a 10-year warranty.
- High charge and discharge power: at up to 180 A each way, stored energy is available quickly even under heavier demand.
- Weatherproof to IP66: usable from -20 to 55 °C and at altitudes up to 4,000 m.
- Space-saving stacking: the battery sits mechanically on the system and is secured with the supplied locking kit.
Questions about this unit
Do I need to register this set?
Rules differ by country and network operator — check what applies where you are. In most markets a plug-in system is notified to the local grid operator, and the battery falls under the same notification as the solar it sits behind. The paperwork is included with the delivery.
Does the output rating breach the export limit?
No. Export limits apply to the power fed into your home wiring. In the manufacturer's app you set the export to whatever your market allows; the higher rated output is used for connected loads and for internal charging.
Can I add more batteries later?
On the modular units, yes. The extra pack stacks, connects with the supplied cable and is recognised in the app after a short firmware sync. No work on your home wiring is needed. The maximum configuration is listed in the technical data.
Can it stay outside in winter?
With IP65 and cell heating, yes: discharge down to −20 °C, charging from around 0 °C, with the heater covering the range below. Choose a rain-sheltered spot on a wall and leave clearance at the vents.
How long do the rated cycles last, and what does the warranty cover?
At roughly 250 to 300 full cycles a year, 6,000 cycles is more than 15 years of use down to 80 % remaining capacity. The manufacturer warranty is listed in the technical data; your statutory rights apply on top.
How is it installed, and do I need an electrician?
Panels plug in, the unit stands on a level surface or mounts with the supplied bracket, and it connects to a standard socket. The plug-in configuration does not require an electrician. For a fixed feed-in point or metering in the consumer unit, use a qualified electrician.
