Battery retrofit in Inverness
Can I retrofit a battery to my solar panels in Inverness?
Quick answer: Yes, we install batteries in Inverness and the surrounding Highland area. Inverness is in the SSEN DNO area. Rural Highland properties may have three-phase supply and longer G99 lead times. A no-obligation survey confirms your exact compatibility and price.
Inverness is the gateway to the Highlands and falls within the SSEN distribution area. The city has a mix of granite and sandstone properties, newer developments, and rural surroundings where self-consumption of solar generation is particularly valuable.
DNO: SSEN
Inverness is served by SSEN (Scottish and Southern Electricity Networks). Batteries over 3.68kW per phase require G99 prior approval — typically 4 to 8 weeks, though rural Highland connections may take longer due to network capacity checks. Smaller systems use G98 notification within 28 days of install. We handle all DNO paperwork as part of the process.
Housing types and battery siting
Granite and sandstone properties in the city centre may require careful cable routing. Newer developments in Culloden, Milton of Leys and Smithton typically have loft or garage space and modern wiring that simplifies the retrofit. Rural properties around the Moray Firth often have three-phase supply, which affects G99 thresholds and battery configuration.
Typical system sizes and yields
Existing solar systems in Inverness range from 2kWp to 4kWp. A typical 4kWp system in Inverness generates roughly 2,680 to 3,080 kWh per year, per MCS MIS 3002 — lower than the Central Belt due to its northern latitude. However, long summer days at this latitude produce extended generation windows that suit battery storage well. These are ranges — a no-obligation survey provides exact figures.
Rural and Highland considerations
Many Highland homes are off the gas grid and rely on electricity or oil for heating, making self-consumption of solar generation particularly valuable. Three-phase supply is more common in rural areas, which can allow larger batteries without G99 prior approval but requires a compatible three-phase inverter. Transport of heavy battery units to Highland locations may add time to the schedule. We discuss these factors with you upfront so the timeline is clear.
Frequently asked questions
Do you install batteries in Inverness?
Yes. We serve Inverness and the surrounding Highland area. Inverness is in the SSEN DNO area. Batteries over 3.68kW require G99 prior approval; smaller systems use G98 notification. We handle all DNO paperwork.
Can I add a battery to my existing solar in Inverness?
Yes — if you have a string inverter installed before 2018, AC-coupling (Tesla Powerwall 3) or a hybrid swap is likely. If you already have a hybrid inverter, a Pylontech US5000 add-on may be possible. Run the compatibility checker to confirm.
