SMILE SERIES

3 kW - 10 kW


Our residential energy storage solution covers 3 ~ 10 kW, and this range is predominantly designed for PV self-consumption, back-up power, load shifting and off-grid solutions for household applications.

Storing renewable energy with AlphaESS - it’s a no-brainer.

Home battery storage systems offer homeowners a strategic solution to manage energy consumption effectively. By storing energy during periods of low demand or harnessing power from renewable sources like solar PV or wind, these systems provide a reservoir of electricity available when energy costs are higher or during outages.

An expert-designed system will be tailored to your household needs, ensuring a seamless and efficient energy management experience that will leave you feeling reassured and secure. The long-term benefits of reduced energy bills and a smaller carbon footprint make it a valuable investment for the future.

Another successful AlphaESS UK G3 and 10.1kWh battery install in Preston

"This AlphaESS kit really is a doddle to install and commission and looks brilliant.

This system will allow the customer to charge using the on-roof solar PV, charge up at night using her off-peak Octopus Energy tariff, and then use that power during the day."

    Retrofitting AlphaESS Home Energy Storage Solutions

    Retrofitting an AlphaESS UK home battery storage system to your existing solar setup can significantly enhance energy independence, optimise savings, and provide reliable backup power, giving you peace of mind. The following provides a guide to areas you should consider when integrating battery energy storage systems into existing solar energy.

    Click on the steps below to find out more about the retrofitting process.

    1. Assess Your Energy Needs and Objectives

    Assessing your objectives for installing battery energy storage at your home is essential. You have an opportunity to take control of your energy consumption and define your goals. Whether you want backup power during outages, reduced electricity bills, or increased solar energy self-consumption, the power is in your hands. Your starting point should be to:

    • Define Goals: Determine whether your primary aim is backup power during outages, reducing electricity bills, or increasing solar energy self-consumption. It could be a combination of these things, and whatever the reason, BESS connected to your home solar system can provide many advantages.
    • Evaluate Energy Usage: Analyse your household's energy consumption patterns to select an appropriately sized battery system. The data is available, and by understanding energy consumption patterns at your home, including peak energy use times and possibly EV charging facilities, you can match a system that provides effective storage and backup power and delivers on the best payback period for you.
    2. Select the Appropriate AlphaESS Battery Storage Solution

    The AlphaESS Smile-G3 Series system is the perfect partner for retrofitting as this range series offers hybrid inverters that can be installed in every scenario in the home, with a variety of inverter sizes (3.68 kW or 5 kW) paired with 4 kWh or 10 kWh battery modules. It features 200% array oversizing and the option to connect a generator for a dual power supply, making it suitable for retrofits and new installations.

    3. Ensure Inverter Compatibility

    The Smile-G3 Series delivers hybrid inverter integration, allowing connection as an AC or DC system. If you are upgrading an existing system, you can hybrid connect, allowing for AC and DC connectivity simultaneously, meaning this unit relay does it all, facilitating seamless integration.

    4. Professional Installation and System Integration

    To ensure the safety and efficiency of your battery energy storage system, using experienced and certified installers is essential. The AlphaESS UK-authorised installer network provides you with access to installers who can ensure proper installation and compliance with local regulations. Our vast authorised installers have direct access to our UK-based technical and customer support, who know our systems and UK BESS safety standards, providing a seamless installation process.

    Once you have chosen your system installer from our Find an Installer portal, they can guide you through each step and will integrate the battery system with your existing solar setup, configuring it to optimise energy storage and usage based on your specific needs.

    5. Utilise Monitoring and Control Features

    With the AlphaCloud Platform, you are in control; monitor system performance, control energy usage, and participate in virtual power plants (VPPs) if desired, giving you a sustainable way to manage your energy and create energy independence. Your authorised AlphaESS UK installer can connect your system to the AlphaCloud platform during installation, ensuring you have the data you need from day one to maximise your system

    6. Safety and Maintenance

    When it comes to safety and longevity, the G-3 Series delivers on both counts. The AlphaESS brand and systems are recognised globally as a market leader in creating safe and future-proof products. Integral to this is our approach to safety compliance, where our system design, product manufacturing, and warranty deliver impressive results, all with safety in mind. We use lithium iron phosphate (LiFePO₄) batteries, known for their stability and long cycle life.

    Regular Maintenance is essential with any system, and purchasing and installing a globally recognised brand and product like AlphaESS means you have access to a wide range of authorised companies and trained people for scheduled routine inspections or repairs, ensuring continued optimal performance and longevity of the system.

    By retrofitting your existing solar system with an AlphaESS UK battery storage solution, you can maximise the benefits of your solar investment and ensure greater energy independence and resilience.
