Solar photovoltaic (PV) systems and battery storage are increasingly popular in Staffordshire homes, driven by high electricity prices and growing environmental awareness. The solar panels themselves are installed by MCS-registered solar installers, but the electrical integration of the system with the household supply — including the inverter connection, generation meter, export meter, and battery storage wiring — involves significant electrical work that must be carried out correctly.
A solar PV system converts sunlight into DC electricity via the solar panels, then converts this to AC via an inverter. The inverter output is connected to the household consumer unit via a dedicated circuit and a generation meter. Excess generation that is not consumed by the household is exported to the grid, recorded by a smart export meter. The entire connection to the consumer unit must be carried out by a competent electrician.
Battery storage systems — such as those by Tesla Powerwall, GivEnergy, or Growatt — add a further layer of complexity. The battery connects between the solar inverter and the consumer unit, or in some systems directly to a dedicated backup circuit. A DC-coupled battery stores energy directly from the solar panels; an AC-coupled battery stores energy from the AC system (either solar generation or off-peak grid). All battery storage systems require a dedicated electrical connection and appropriate protection.
Homeowners considering solar and battery storage should involve an electrician in the system design before committing to a solar installer. The condition of the existing consumer unit, available space for additional metering and wiring, and the routing of cables from the roof to the consumer unit are all factors that the electrician needs to assess. DP Power Solutions works alongside MCS-registered solar installers to provide the electrical connection and certification work for solar and battery storage installations across Staffordshire.
