About this service
Battery storage captures electricity from solar generation or the grid and releases it later. A system may reduce imported energy, support time-of-use tariffs or provide selected backup functions when designed for that purpose.
Capacity in kilowatt-hours, power in kilowatts and usable operating modes are different decisions. Location, fire safety, temperature, noise, inverter compatibility, metering and what should happen during a power cut all need to be agreed.
Common problems we help with
Solar export is high during the day
A battery may store surplus for evening use if its capacity and charge rate suit the generation profile.
Tariff charging is poorly controlled
Incorrect schedules can charge or discharge at unhelpful times.
Customer expects whole-house backup
Not every battery provides backup, and available power may not support all circuits.
No suitable equipment location
Weight, ventilation, temperature, escape routes, clearances and cable access restrict placement.
How we carry out the work
Review consumption and objectives
We examine available data and decide whether savings, solar use, tariff shifting or resilience is the priority.
Design battery, inverter and protection
Power, capacity, location, metering, isolation and backup circuits are specified.
Install, commission and set operating modes
The system is tested, connected to monitoring and explained to the customer.
What is normally included?
- Initial discussion about the property, symptoms, priorities and timescale
- Assessment of the relevant circuit, equipment, access and existing protection
- A written scope for the proposed battery storage installation work
- The agreed installation or repair work, with disruption kept to a reasonable minimum
- Inspection, electrical testing and appropriate handover documentation
Before the work starts
- Current consumption, proposed generation and the customer’s operating priorities
- Existing metering, distribution equipment and available installation space
- Equipment compatibility, monitoring and safe shutdown arrangements
- Whether backup operation, time-of-use tariffs or future expansion are required
What affects the price?
The price depends on the existing installation and the amount of work required. For battery storage installation, the main factors normally include:
- System capacity and equipment specification
- Cable routes, access and distribution alterations
- Monitoring, backup and control functionality
- Testing, commissioning and coordination with other installers
Testing, certificates and handover
Once the installation work is complete, we inspect and test it and provide the records that apply to the job.
- Operating modes and monitoring demonstration
- Electrical test and commissioning records
- Isolation and shutdown information
- Equipment documentation and maintenance expectations
Battery Storage Installation questions
Can a battery be added to any solar system?
Often, using AC- or DC-coupled arrangements, but inverter compatibility and existing design must be checked.
Will it run an electric shower in a blackout?
Large loads may exceed backup output. Essential circuits are usually selected deliberately.
Can the battery charge from the grid?
Many systems can, subject to product capability, settings, tariff and network requirements.
Booking the work
What happens after you contact us
1. Discuss the job
Tell us about the property, the symptoms or the result you want. Photographs and model numbers are often helpful.
2. Inspect and quote
We check the relevant installation and give you a written quotation showing what is included.
3. Complete and test
We carry out the agreed work, verify it electrically and explain any controls, labels or certificates at handover.
