Solar battery storage companies

Find a company for your type of installation

This category is a starting point for finding companies associated with solar batteries in existing directory records. Ask whether they install batteries alongside new panels, retrofit storage to existing PV, or support equipment already installed. Those are different services: an installer selling new systems may not diagnose every older battery or inverter. For a fuller comparison checklist and companies with reviewed service statements, use our solar battery installers guide.

Give the installer useful information

Share your postcode, annual electricity consumption, available half-hourly consumption data, existing solar system size and inverter make and model. Explain whether your priority is using more solar generation at home, charging at different tariff times or supplying selected circuits during an outage. These goals may require different equipment and settings. Ask which assumptions the proposed design uses and avoid comparing battery capacity alone.

Compare usable capacity, power and installation work

Ask for usable storage in kWh and the charge/discharge power in kW, along with the exact equipment models. Request a written specification covering electrical work, monitoring, access, commissioning, warranty, maintenance and any exclusions. A battery advertised online without installation is not directly comparable with a complete installed quotation. Ask how the system interacts with existing export metering, inverter limits and warranties before agreeing to a retrofit.

Check backup capability separately

Do not assume a battery will power the property during a grid outage. Ask whether the proposed system includes backup operation, which circuits it supplies and its operating limits. Establish whether additional equipment and electrical work are included in the quote. For a permanently independent supply, use the separate off-grid solar category.

Check the company and product support

Confirm the company’s current postcode coverage, support for the proposed model and any manufacturer relationship. Directory categories are not independent certification. Request separate product and workmanship warranty terms and identify your contact if the installer stops supporting the equipment. Our brand guides provide product-specific questions and links to manufacturer resources.
