Frequently Asked Questions

While solar panels work without a battery, adding one significantly increases your energy savings. Without a battery, you only use solar electricity when the sun is shining and your panels are generating. A battery stores excess daytime energy for use in the evenings when electricity is most expensive. Most households use 50–70% of their solar generation with a battery, compared to 30–40% without one.

Modern lithium-ion solar batteries typically last 10–15 years or more. The batteries we install from Tesla, Hanchu, Fox ESS, and Sigenergy are designed for 6,000–10,000 charge cycles, which translates to 15–25 years of daily use. Our lifetime warranty on batteries gives you complete peace of mind.

Yes, if you have a hybrid inverter and battery system. During a power cut, a hybrid system can disconnect from the grid and power your essential appliances using stored battery energy. Not all systems offer this — it depends on the inverter type. Our team designs systems with backup capability if this is important to you.

Battery size depends on your energy usage and solar panel system. A typical UK household uses 8–10kWh per day. A 5kWh battery covers evening usage for most smaller households, while a 10–14kWh battery provides more independence and better backup during outages. Our free survey includes an analysis of your energy usage to recommend the right battery size.

Yes, we can retrofit a battery storage system to an existing solar installation. Depending on your current inverter, we may be able to add a battery-compatible unit or install a separate battery inverter. Our team assesses your existing system during a free survey and designs the most cost-effective solution.

A single-room split air conditioning system typically costs £1,500–£3,000 installed, depending on the unit size and installation complexity. Multi-room systems cost more depending on the number of indoor units. All our installations include the indoor and outdoor units, refrigerant pipework, electrical connections, and commissioning. We provide detailed quotes following a free site survey.

Yes, modern air conditioning systems are reversible heat pumps — they can cool your home in summer and heat it in winter. They're extremely energy efficient for heating, typically producing 3–4 units of heat for every unit of electricity consumed. This makes them a cost-effective supplement or alternative to traditional central heating, especially in individual rooms or extensions.

We recommend annual servicing for domestic air conditioning systems and biannual servicing for commercial systems. Regular maintenance ensures optimal performance, energy efficiency, and air quality. ElectriFusion Solutions offers scheduled maintenance contracts that include annual or biannual service visits, priority emergency response, and discounted repair rates.

Modern split air conditioning systems are remarkably quiet. Indoor units typically operate at 20–30 decibels — quieter than a whisper. Outdoor units are slightly louder but are designed to minimise noise disturbance. Our team positions outdoor units to comply with building regulations and minimise any impact on you or your neighbours.

We hold seven industry accreditations: MCS Certified (solar PV and battery storage), NAPIT Registered (electrical installation), TrustMark Endorsed (government quality mark), RECC Member (consumer code), CHAS Regulated (health and safety), REFCOM Regulated (air conditioning F-gas compliance), and CTSI Approved Code (trading standards). This comprehensive accreditation portfolio ensures the highest standards of quality, safety, and consumer protection.
