Use solar later
Store suitable surplus generation during the day and use it when household demand rises later.
Add this goal to my plan →Solar battery storage
Keep more of your solar for when you need it.
Start with your household usage, solar surplus and backup goal — then size storage around the job it needs to do.

Actual energy flow depends on the final equipment, settings, available solar generation and household demand.
Start with the purpose
What do you want your battery to do?
The answer should guide capacity, equipment and the way your system is configured.
Increase self-consumption
Use more of the electricity generated at your property instead of exporting every available surplus unit.

Define which loads matter during an outage, then confirm the required equipment and operating limits.

A considered recommendation
Six things to review before choosing storage.
A battery decision becomes clearer when it is connected to real household data and a defined purpose.
- 01Your daytime solar surplus across different seasons
- 02How much electricity your home uses in the evening
- 03The loads you want supported if backup is required
- 04Inverter and battery compatibility
- 05Where the battery can be mounted and cabled at your property
- 06Your tariffs, export rate, budget and future plans
Solar + stored energy
Two packages with Cell-X storage.
Array size is only a starting point. The battery fit still depends on your generation, usage and storage objective.

Battery storage answers
Frequently asked questions
Will a battery power my whole home during an outage?
That should never be assumed. Backup capability depends on the inverter, system design, battery state, available power and the circuits selected for support. The proposal should name the supported loads and explain the operating limits.
Ask about my propertyCan I add a battery to an existing solar system?
It may be possible, but the existing inverter, switchboard, solar array and monitoring need to be reviewed. Compatibility and any additional equipment should be confirmed before a recommendation is made.
Ask about my propertyHow large should my solar battery be?
Capacity should be considered alongside your evening use, typical solar surplus, backup objective, inverter limits and budget. A larger nominal capacity is not automatically the best fit for every property.
Ask about my propertyWho installs the battery?
In Canterbury, Cell-X Solar’s registered electricians install, connect and certify it, and package prices include standard installation. Outside Canterbury, ask us about options for your area.
Ask about my propertyDoes a battery guarantee lower power bills?
No. The result depends on how the system is used, solar generation, tariffs, export rates, equipment losses, control settings and cost. Any financial estimate should show its assumptions and remain an estimate rather than a guarantee.
