Frequently asked questions about home battery installation

The survey must first confirm cupboard and location are suitable. Separate meter cupboard work may follow on its own visit. Material and installer scheduling come next — especially in busy months. That is normal process, not admin delay. After the survey you get a realistic timeline.

You cannot always tell yourself. Count free breakers, check for old fuse boards or one cupboard shared by solar, induction and EV charger — upgrade is more likely. Your installer assesses this at survey and explains whether one extra circuit suffices or a larger board is needed — without you measuring.

Opening the board sometimes reveals something unexpected — old wiring or a full rail. The installer prefers to stop rather than work unsafely. Small fixes may happen same day; larger work is rescheduled. That is why survey and optional prior cupboard visit matter.

Only if someone else aged 18+ is present and reachable for questions and handover. The installer cannot work in your meter cupboard or finish without supervision. Stepping out briefly is usually fine; being away all day with no contact can cancel the appointment.

Usually not. Only circuits being worked on may lose power briefly — often minutes to half an hour around connection. Fridge and freezer are usually on other circuits. The installer warns before switching. Avoid critical home office work during cupboard connection.

Limited: drilling for fixings, sometimes a cable pass, unpacking materials. No digging or major construction. In terraced housing neighbours may hear brief drilling — usually one morning to afternoon, not multiple days. Dust is minimised; the installer tidies after handover.

No. Only models rated for outdoor use (IP rating) within system temperature limits. Wall, rain and sun on the spot matter too. The survey decides if outdoor is safe. If not, garage or utility room is usually the alternative — not a DIY choice.

Often yes, depending on cupboard and chosen system. Inverter coupling differs from an existing solar setup. That is discussed in consultation — not every combination is standard. The survey confirms whether your situation is technically feasible.

It functions after handover, but software may fine-tune to your consumption and solar over days to weeks. Temporary odd charge levels or app alerts are often normal. Persistent fault codes mean contact the installer — not DIY cupboard work.

The battery itself has manufacturer product warranty — often several years on the unit. Mounting, wiring and connection fall under agreements with your installer. Before handover, ask explicitly about installation warranty and who to call for faults. Those are two separate tracks.

Usually: date, work performed, test results (charge/discharge), photos of mount and cupboard connection, serial numbers and handover confirmation. Useful for warranty and future sale. If something is missing, ask before the installer leaves — not weeks later.

Little. Keep ventilation clear, do not stack items against the unit, and check app or display for fault alerts. Do not open internal battery parts yourself. The manufacturer may advise inspection intervals in the manual. You do not re-do mounting work yourself.
