PowerHub ONE: modular plug-in home battery (LFP, 2.4–12 kWh) as back-up and satellite storage for Marbella villas, guest houses and pool houses. Verified specifications.
A modular Dutch-engineered home battery that sits alongside your main solar installation: silent back-up for the essentials, and self-contained storage for guest houses, pool houses and staff quarters where a full roof installation makes no sense.
Most villas we work on in Marbella, on the Golden Mile, in Puerto Banús and in Nueva Andalucía already justify a full solar installation with a large high-voltage battery. But a property is rarely one single building. There is the guest house, the pool house, the staff apartment, the gym or the garage block at the bottom of the plot — buildings with modest consumption, their own meter or a long cable run, where trenching a new circuit back to the main technical room costs more than the energy it would ever save. That is exactly where a modular plug-in battery earns its place. PowerHub ONE is a Dutch-engineered, AC-coupled home battery built around LFP modules of 2.4 kWh each; one Main Unit takes one to five modules, so a system holds between 2.4 and 12 kWh. On an ordinary socket it delivers up to 800 W, and on a dedicated circuit installed by a certified electrician up to 2.4 kW peak. Its back-up output is rated at 2.4 kW nominal with a changeover time of ≤10 ms, which in practice means the lighting, the fridge, the router, the gate and the alarm never notice a cut in supply — useful in a house that stands empty for months. The engineering is conservative in the way owners of high-value property tend to want: LFP chemistry rather than NMC, aerosol fire suppression built into every module, an IP65 enclosure, natural cooling so there is no fan noise near a terrace, and system-level protections for over- and undervoltage, overcurrent, short circuit, over-temperature, anti-islanding and residual current. PowerHub covers the unit with a 10-year product warranty. Solar Marbella positions PowerHub ONE as a complement, never a replacement: your main roof array and hybrid battery carry the villa, while PowerHub ONE handles the outbuildings and the critical circuits. We assess placement, the electrical circuit and whether your existing inverter and metering setup make the combination worthwhile before recommending anything.
No, and we would not sell it that way. A villa with a pool, air conditioning and an electric car needs a roof array with a hybrid inverter and a large battery. PowerHub ONE is a complement: 2.4 to 12 kWh of modular storage for a guest house, pool house or staff apartment, or as a silent back-up for critical circuits in the main house.
There are two levels. On an ordinary shared socket the system delivers up to 800 W (0.8 kW nominal). On its own dedicated circuit, installed by a certified electrician, it delivers up to 2.4 kW peak (10.43 A at 230 V) according to the datasheet. The back-up output is rated 2.4 kW nominal with a changeover time of ≤10 ms.
PowerHub ONE uses LFP cell chemistry, which is the more thermally stable choice for residential storage, and every battery module has built-in aerosol fire suppression. The enclosure is IP65 rated with natural cooling, so there are no fans and no noise, and the system carries protections for over- and undervoltage, overcurrent, short circuit, over-temperature, anti-islanding and residual current. Placement always follows the official PowerHub installation documentation and Spanish electrical regulations.
PowerHub is a Dutch home-energy brand operated by ISAJA B.V. in Losser, the Netherlands. It was built by the same business partner behind Mi Techo Solar S.L., the company behind SolarMarbella.es, so the two brands work together closely: PowerHub develops and warranties the product, Solar Marbella advises on and integrates it on the Costa del Sol. Full product information is on powerhubone.com.
PowerHub provides a 10-year product warranty on PowerHub ONE under its own warranty terms, and handles technical claims directly. Solar Marbella remains your local point of contact for placement, electrical work, integration with your existing solar system and any on-site assessment.
PowerHub ONE is AC-coupled, so it does not need to talk to your inverter to function — it charges and discharges on the AC side and reads consumption through supported smart meters and third-party platforms. Whether it improves your position under compensación simplificada depends on how much surplus you currently export and when you consume it, which is exactly what we check during a free consultation before recommending it.
