Alpha ESS Solar Batteries & Inverters
Professionally installed by Viable Power
At Viable Power, we install a range of reliable, high-performance solar battery systems from trusted manufacturers — including Alpha ESS.
Known for its innovative SMILE series, Alpha ESS designs modular home batteries that combine smart technology, elegant design and proven safety. We install Alpha ESS systems across Surrey, Hampshire and the South East, helping homeowners make the most of their solar power and gain greater control over their energy use.
Why Choose Alpha ESS?
Founded in 2012, Alpha ESS has become one of the world’s leading names in solar energy storage, with more than 200,000 systems installed worldwide. The company is known for quality engineering, long-term reliability and intelligent energy management — making its products a solid choice for UK homes and small businesses.
The SMILE series combines inverter, battery modules and control system in one neat, all-in-one cabinet. Each model is compact, quiet and efficient, with typical capacities from 5 kW / 10 kWh upwards. The modular design allows you to increase storage later by adding more battery modules, so your system can adapt as your energy needs grow.
All Alpha ESS batteries use Lithium Iron Phosphate (LiFePO₄) chemistry — recognised as one of the safest and most stable battery types for home storage. The company’s approach ensures high safety standards, supported by advanced battery management systems (BMS) for protection against over-voltage, temperature and current fluctuations.
Alpha ESS systems also feature fast automatic switchover to backup power during an outage, keeping essential circuits running with minimal disruption. Through the AlphaCloud app, you can view solar generation, battery status and energy use in real time — giving you simple, practical control over your home energy.
A Smart Choice for UK Homes & Businesses
Alpha ESS systems are designed to perform reliably in UK conditions and meet G98/G99 grid-connection standards. The company has an established UK presence, providing local support and warranty services to ensure smooth aftercare.
Their hybrid inverter models work with both new and existing solar installations, giving you flexibility whether you’re starting your renewable journey or upgrading an existing system. Built-in intelligent power management allows Alpha ESS systems to store surplus solar energy during the day and, depending on your setup, charge from the grid during cheaper off-peak hours.
For homes on time-of-use tariffs such as Octopus Go or Intelligent Octopus, this can help you lower electricity costs and make the most of every kilowatt-hour you generate.
Alpha ESS systems are also recognised for their build quality and design. The SMILE-G3 model received a Red Dot Design Award, and the company has been ranked among the Top 5 Residential Storage Providers globally by IHS Markit — giving you confidence that you’re choosing proven, well-supported technology.
