Extra stored energy for your Anker SOLIX system
The BP3800 is not a standalone product: it is a storage module that connects to an Anker SOLIX power station or system designed to accept expansion units. With 3840 Wh on board, it stretches the time your devices stay powered when the grid drops out or the sun is scarce. Before buying, check the manufacturer’s manual to confirm that your main unit accepts this module and how many expansions it supports.
Who benefits from it
Home users
In a house, a module of this size can keep a fridge, a router and some lighting running through a long outage. Owners of solar panels can also bank the day’s production and use it in the evening. The larger the reserve, the easier it becomes to spread consumption across the night without drawing on the grid at the hours when people get home, cook, wash or recharge their devices.
Professional users
A tradesperson, a food-truck operator or a film crew gets a generous reserve for tools, lights or point-of-sale gear, with no noise and no exhaust.
Design and build
The battery relies on LiFePO4 chemistry, rated at 3,000 cycles to 80%+ capacity. The case measures 392,7 x 354,7 x 262 mm and weighs 34,5 kg, so it is meant to sit on the floor or on a sturdy support rather than be carried around by hand every day.
Setting it up
- Pick a flat, dry and stable spot able to carry 34,5 kg.
- Leave clear space around the case so air can circulate.
- Switch off the main unit before connecting the expansion.
- Use only the cables specified by the maker and follow the procedure in the manual.
Any link to a home’s electrical panel must be handled by a qualified installer.
Strengths of this model
- Large 3840 Wh capacity in a single module.
- LiFePO4 cells intended for repeated cycling.
- Compact format for the amount of energy stored.

Safety advice
Never cover the case and keep it away from heat sources. Avoid moisture: since no ingress rating is supplied, place it where rain and splashes cannot reach it. Stay within the limits given in the manual, and stop using the unit if the case is deformed, damaged or unusually hot.
Care and storage
Wipe the case with a dry cloth. If the module will sit idle for several weeks, store it partly charged in a mild, ventilated room and check the charge level from time to time, as manufacturers commonly advise.
Inspect the connectors and cables regularly: a dirty socket or a visibly worn lead should be replaced with an original part. Before moving the module, disconnect it, let it cool down and plan on two people to lift it, because 34,5 kg is awkward to handle alone.
