Solar PV & Battery Storage Solution for Maximum Energy Bill Savings

Cutting electricity costs through smart solar generation and battery load shifting with AlphaESS SMILE-G3-S8 inverter and 28.8kWh of battery storage.

Reducing Household Energy Bills Through Solar and Battery Storage

Across the UK, rising electricity prices are pushing homeowners to explore smarter ways to manage their energy use. For many, the combination of solar PV and battery storage represents the most effective route to long-term savings, particularly when paired with off-peak tariffs that allow batteries to charge at low cost overnight and discharge during expensive peak hours.

This customer approached Ideal Electrical Solutions with a clear goal: to reduce their electricity bills as much as possible. With the right system design, combining solar generation with intelligent battery load shifting, the potential to eliminate grid electricity costs entirely was within reach. By capturing solar energy during the day and charging the battery at lower off-peak rates overnight, the system is designed to meet the vast majority of the home’s energy needs without drawing expensive peak-rate electricity from the grid.

The solution: an AlphaESS SMILE-G3-S8 inverter paired with 28.8kWh of battery storage and a 5kW solar PV array was professionally designed and installed by Ideal Electrical Solutions.

Delivering a high-performance system built to maximise savings from day one.

DISCOVER THE PROJECT AT A GLANCE

Installer: Ideal Electrical Solutions
System: AlphaESS SMILE-G3-S8 Inverter with 3x AlphaESS 9.6kWh Batteries

Project Goal: Install solar PV and battery storage to offset off-peak charging costs and maximise savings through load shifting
Installed PV Capacity: 5kW Solar
Battery Storage: 28.8kWh installed capacity
Key Objective: Reduce electricity costs through solar generation and battery load shifting using off-peak energy tariffs
Core Benefit: Lower energy costs by maximising solar generation and battery storage while reducing reliance on peak-rate electricity

By putting the battery storage in, with the rates that they’re getting, they could save up to 75% on their electric bills. But by putting the solar in as well, that will bring it to 100% savings.

A High-Performance System Designed Around Load Shifting and Solar Maximisation

To achieve the greatest possible reduction in electricity costs, Ideal Electrical Solutions selected an AlphaESS SMILE-G3-S8 8kW hybrid inverter, paired with three AlphaESS 9.6kWh batteries, providing a total storage capacity of 28.8kWh. This combination provides the system with both the power output and the storage capacity needed to support strategic load shifting, charging from cheap off-peak tariff rates overnight and from solar generation during the day, then discharging to cover the home’s energy needs during peak hours.

The 5kW solar PV array works alongside the battery to maximise self-consumption, ensuring that as much of the home’s electricity demand as possible is met by either solar generation or stored energy rather than grid imports. Together, the solar and battery system create a comprehensive energy solution with the potential to reduce electricity bills by up to 100%.

Ideal Electrical Solutions chose the AlphaESS SMILE-G3-S8 for its straightforward installation process and exceptional technical support, factors that give both installers and customers confidence in the system's long-term reliability.

The Challenge — Reducing Electricity Costs and Maximising Off-Peak Tariff Benefits

The client’s primary goal was to reduce their electricity bills as much as possible. With overnight charging costs and peak-rate grid electricity eating into household budgets, a system capable of intelligent load shifting, storing cheap energy and using it at the right time, was essential. The solution needed to work seamlessly with an off-peak tariff strategy while also capturing solar generation during daylight hours to further drive savings.

System Features and Benefits

Powerful Hybrid Inverter:
The AlphaESS SMILE-G3-S8 8kW hybrid inverter intelligently manages both solar generation and battery storage, optimising energy flows to always maximise savings.
Substantial Battery Capacity:
Three AlphaESS 9.6kWh batteries provide 28.8kWh of total storage, enough to store significant quantities of cheap off-peak energy and solar generation for use throughout the day.
Smart Load Shifting:
The system charges overnight at off-peak rates and from solar during the day, then discharges to meet household demand during expensive peak periods.
Solar Self-Consumption:
The 5kW PV array maximises on-site generation, reducing the need for any grid imports during daylight hours.
Simple Installation & Outstanding Support:
The SMILE-G3-S8’s clear installation guide and rapid technical support, with faults typically resolved within 5 to 10 minutes of calling, make it Ideal Electrical Solutions’ system of choice for confident, efficient deployment.

Demonstrating Visible Results & Benefits

Up to 75% Bill Reduction from Battery Alone: Load shifting using off-peak tariff rates can reduce electricity bills by up to 75% without any solar contribution.
Up to 100% Savings Potential: With solar PV added to the battery system, the customer has the potential to eliminate grid electricity costs entirely.
Rapid Fault Resolution: AlphaESS technical support picks up within 5 minutes, with most issues diagnosed and resolved in under 10 minutes, minimising any downtime for Ideal Electrical Solutions and their customers.
Optimised Tariff Performance: The system is built to work hand-in-hand with off-peak energy tariffs, ensuring the battery charges at the lowest available rate every night.
