Case Study: Smarter Energy at Home – Solar PV, Battery Storage & EV Charger Integration

Introduction

As part of their commitment to sustainable living and energy independence, the homeowner partnered with M J Wallace Limited to install a solar PV system, battery storage, and a solar-integrated EV charger.

The goal was to reduce reliance on grid electricity, cut energy costs, and create a smart home energy ecosystem capable of charging an electric vehicle directly from solar power.

Challenge

The client wanted a comprehensive renewable energy solution that could:

Generate clean electricity on-site.
Store excess power for use during evenings and cloudy periods.
Seamlessly charge an electric vehicle from solar generation.
Provide visibility and control through a user-friendly monitoring app.
Deliver long-term savings and support their personal carbon reduction goals.

Solution

M J Wallace Limited designed and installed a fully integrated solar, battery, and EV charging system optimised for energy efficiency and convenience.

System Overview:

Solar Panels: 27 × Canadian Solar 455W Mono TOPHiKU6 All Black – Total Capacity: 12.3kWp
Inverter: 1 × Fox ESS KH 10kW 1ph Hybrid Inverter
Battery Storage: 2 × Fox ESS EP11-H 10.36kWh lithium-ion batteries (total 20.7kWh storage)
EV Charger: FoxESS L-Series EV Charger
Mounting System: K2 SingleRail and Fastensol pitched roof mounting system
Monitoring: Smart Fox ESS app providing real-time system performance and energy usage data

The hybrid inverter and integrated battery storage allow solar energy to power the home during the day, charge the battery for nighttime use, and supply clean energy directly to the EV charger when available.

Our Approach

From initial site assessment to final commissioning, M J Wallace Limited provided a complete turnkey service.

Our team handled:

System design, DNO applications, and certification.
Professional installation of solar panels, batteries, and EV charger.
Full electrical testing and MCS certification.
User setup and training on the Fox ESS monitoring app.

By working closely with the client, we ensured the installation was efficient, safe, and optimised for maximum self-consumption and energy independence.

Benefits

☀️ Energy Generation: Produces approximately 9,335 kWh per year, covering most of the household’s annual demand.
🔋 Energy Storage: 20.7kWh of battery capacity allows solar energy to be stored and used overnight.
🚗 EV Charging Integration: The EV charger intelligently draws from solar and battery power, reducing grid reliance.
💷 Cost Savings: The system is expected to reduce grid electricity use by over 60%, cutting annual bills significantly.
🌱 Carbon Reduction: Approximately 1.9 tonnes of CO₂ saved annually, equivalent to planting 87 trees or avoiding over 6,700 miles of car travel.
📱 Smart Control: Real-time monitoring via the Fox ESS app provides full visibility of generation, storage, and usage.

Results

The integrated solar, battery, and EV charger system has transformed the client’s home into a smart energy hub.

Key outcomes include:

Significant reduction in grid electricity purchases.
Seamless daily operation – charging the EV using stored solar energy.
Improved energy independence and resilience against rising electricity prices.
Tangible carbon savings supporting a move toward net zero living.

This project demonstrates how M J Wallace Limited delivers modern, connected renewable energy systems that combine efficiency, performance, and sustainability.
