Case Study: Smart Solar & EV Charging – Domestic Energy Upgrade in Lichfield

Introduction

M J Wallace Limited was appointed to design and install a domestic solar PV system with integrated battery storage and EV charging at a residential property in Lichfield.

The homeowner wanted a system that would reduce grid reliance, cut energy costs, and enable direct EV chargingusing clean, self-generated solar power – all managed through an easy-to-use smart app.

Challenge

The project aimed to deliver a compact, high-performance system that could:

Maximise on-site generation within available roof space.
Provide battery storage for evening and off-peak use.
Integrate EV charging powered directly by solar.
Reduce carbon footprint and long-term energy bills.
Meet full MCS and NICEIC certification standards for compliance and insurance.

Solution

M J Wallace Limited designed and installed a 9.4kW solar PV array paired with a Fox ESS hybrid inverter, 10.4kWh battery storage, and 7kW EV charger.

System Details

Solar Panels: 20 × Aiko Neostar 3S 470W All Black ABC N-Type Mono (total 9.4kWp)
Inverter: Fox ESS KH 10kW 1ph Hybrid Inverter
Battery Storage: Fox ESS EP11 10.36kWh lithium-ion with self-heating function
EV Charger: Fox 7kW L Series 1PH with Type 2 Cable
Mounting System: K2 SingleRail and Fastensol pitched roof systems
Performance: Estimated annual generation 6,534 kWh
Carbon Savings: Estimated 1.35 tonnes of CO₂ saved per year

All components were installed to the highest standards, including full DC and AC cabling, isolation protection, and consumer unit upgrades for safety and efficiency.

Our Approach

From the initial design and DNO application to final certification, M J Wallace Limited managed every aspect of the project.

Our team provided:

Detailed system design, shading analysis, and performance modelling.
Full installation and electrical works, including scaffolding and roof integration.
Smart commissioning of the Fox ESS system and EV charger.
MCS, NICEIC, and Building Control certification, ensuring full regulatory compliance.
