Energy Storage That Stays Out of Your Way
Floor space in a modern home is precious. You might have a tidy garage, but it's already full. A utility room lined with shelves. A hallway where every inch counts. The idea of adding a big battery cabinet that eats up a square metre of real estate just doesn't work. The WBP Series is the answer for exactly those situations. It's a lithium iron phosphate battery designed to be hung on a wall like a piece of cabinetry, keeping your floor clear and your energy storage discreetly out of the way.
LiFePO₄ Chemistry That Lasts
Under the clean cover, the WBP uses the same safe, stable lithium iron phosphate cells that have become the standard for serious residential storage. The chemistry is inherently resistant to thermal runaway, so it doesn't carry the fire risk of other lithium types. More importantly, it's built for endurance. The cycle life is rated at 8,000 cycles to 80% depth of discharge. For a household that charges by day and discharges through the night, that translates to over 20 years of daily use before the pack shows meaningful degradation. The design life is a conservative 10 years, but in practice, the battery will likely still be holding a useful charge long after the warranty has expired. You're not looking at a lead-acid replacement treadmill; you're making a one-time investment that matches the lifespan of your solar panels.
Wall or Floor—You Decide
The default installation is wall-mounted. Two brackets, a sturdy wall, and the battery hangs like a slim cabinet. That keeps it elevated away from damp floors and any accidental knocks from the lawnmower. But the WBP doesn't force you into one configuration. If your walls are concrete block and you'd rather not drill, you can simply stand the battery on the floor. And because the enclosure is designed to stack, you can place multiple units one on top of another to build a compact, vertical battery bank. When you need more capacity down the line, you add another WBP—up to 16 packs in parallel. That's an enormous amount of stored energy, all managed from a single battery bus. You start with what you need for tonight's load, and you scale to cover a full weekend of backup without ever changing the fundamental architecture.
Smart BMS, Visible Status
Inside each unit is a Battery Management System that does more than just prevent over-voltage. It balances cells continuously, monitors state of charge and state of health, and protects against over-current, short circuits, and extreme temperatures. The BMS data is presented locally on a front-panel display: charge percentage, pack voltage, current flow, and any active alarms. You don't need to pull out your phone to check if the battery is full—a glance at the screen tells you everything. For deeper integration, the BMS talks over RS485, SNMP, WiFi, and Bluetooth. That open protocol stack means the WBP can communicate directly with a wide range of hybrid inverters and charge controllers from different manufacturers. No proprietary handshake needed, no gateway box. Just clean, standard data that your inverter can use to make smart charging decisions.
High Discharge Rate for Real Loads
A battery that only handles lights and routers isn't much use in a real home. The WBP is built with a high continuous discharge rate, so it can handle a well pump starting up, a kitchen full of appliances during a blackout, or a workshop tool without the voltage dipping and tripping your inverter's low-voltage cutoff. Whether you're running off-grid or just using the battery to dodge peak utility rates, the power delivery is stable and confident.
Where the WBP Works Best
This battery is ideal for homeowners who are adding storage to an existing solar system but don't have a spare corner for a floor-standing cabinet. It's also a favorite with installers because it adapts to the site. You can walk into a job and mount it on the wall if there's a stud bay available, or stack it in a closet if there isn't. The 25.6V (24V) and 51.2V (48V) voltage options cover the majority of residential hybrid inverters and off-grid chargers. Whether you're putting together a grid-tied system with backup, a small off-grid cabin, or a comprehensive whole-home energy management setup, there's a WBP configuration that fits physically and electrically.
In short, the WBP Series takes the long-life, safe LiFePO₄ technology you expect and puts it in a package that respects your space. It hangs, it stacks, it scales, and it talks to your inverter without fuss. If floor space is the only thing standing between you and energy independence, this battery removes that barrier.
