Frequently Asked Questions

Does a PowerHub ONE replace a full solar installation on a Marbella villa?

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.

How much power can PowerHub ONE actually deliver?

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.

Is it safe to install a battery inside a guest house or garage?

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.

Who is PowerHub and what is the relationship with Solar Marbella?

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.

What warranty and support apply in Spain?

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.

Can it work with my existing inverter and Spanish compensación simplificada?

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.
