Meet The Smile G3 Battery Storage
This residential Energy Storage System (ESS) offers a choice between a 3.68 kW or 5 kW hybrid single-phase inverter paired with either 4 kWh or 10 kWh battery modules.
The G3 Series doesn’t stop there—it goes beyond with features like 200% array oversizing and the ability to connect a Generator for Dual power supply options, and that’s just the beginning.
Why Choose the AlphaESS G3?
With its comprehensive functionality, the G3 Series delivers outstanding value for money and encompasses all the features you’d anticipate from a top-tier ESS system. Compared to other products, it offers superior performance in off-grid scenarios.
Intelligent Hybrid Inverter
Offering a fast response and uninterruptible power supply, the AlphaESS Smile G3 Series Hybrid Inverters features an intelligent modular design and 24/7 monitoring online and via the AlphaESS app and its 10 years 10000 cycle no quibble warranty is one of the best in the market.
Adaptable and Versatile
Rated (IP65) thus offering the flexibility of indoor and outdoor use and can be used completely off-grid as a standard feature or during power outages. With its adaptable battery options and 200% PV input capabilities this really is a versatile system.
Easy Modular Expansion
The building block style has a modular design, with plug-and-play easy installation and expands to meet your needs with 10kWh battery modules.
Works with Smart Tariffs
When combined with an AlphaESS battery, the Alpha Smile G3 Series has been designed to work seamlessly with smart energy tariffs. Contact your energy supplier to find out which tariffs will be the most beneficial to you.
Smart Export Guarantee (SEG)
The Smart Export Guarantee is a support mechanism that ensures people who generate their own electricity are paid for the electricity they export to the grid.
This doesn’t happen automatically, so you must sign up for the SEG tariff.
Quicker Return On Investment
SEG tariffs run separately from your power import tariffs. Therefore, you can benefit from both, helping to reduce your system’s rate of return.

Frequently Asked Questions About Solar Batteries
Will a battery work with my existing panels?
Yes. If you already have solar panels, we can supply and fit a battery to your existing system.
Can I have more than one battery?
Most households only need one battery, however depending on your power requirements we can add more batteries to your system.
Where will the battery go?
The battery system is designed to be wall or ground-mounted – and is usually installed in the loft of your home. For homes without a loft, the installer will be able to give you alternative options, such as the garage or under the stairs.
How long does installation take?
Solar will take approximately 3-4 hours to install a battery in an existing solar panel system. Installing solar panels and a battery will take a day.
Can you save money with a solar battery?
The benefits vary greatly from household to household, as everyone uses energy differently and at different times of the day. However, after completing a remote survey, we’ll be able to provide you with a custom report showing your homes savings with a solar panel and battery system.
