Energy duty
Quantify surplus, evening use, tariff windows or peak periods across representative days.
Battery storage
Would a battery help you use more of your own power?
FLO checks when you use power and what you want the battery to do, so you can decide whether storage is worthwhile.
Every property is different. The free survey checks what is possible before you commit to a system.
The answer you need
How do you choose the right battery size?
Define the objective first, then use real demand and generation data to test how often a proposed capacity will charge, discharge and create value across different seasons.
The property-specific checks
What will FLO check for your property?
We use these details to work out what is practical, what needs more investigation and what the next step should be.
Power duty
Check instantaneous charge and discharge limits against the loads being shifted.
Control and safety
Define operating mode, location, protection, monitoring, warranty and emergency information.
The next step with FLO
What will your assessment and quote cover?
FLO starts with your property, then explains the recommended work, the price, important exclusions and the next steps in writing.

Good to know
Questions you may have.
Can a battery work without solar?+
Yes, where tariff shifting or another defined duty supports it. The model should show how it will charge and create value.
Will a battery run the building in a power cut?+
Only where the equipment and installation include an appropriate backup arrangement. Many grid-connected systems shut down during an outage.
What does usable capacity mean?+
It is the energy available within the allowed operating range, which can differ from the headline nominal capacity.
What might change the recommendation?+
A large battery is not automatically better. Capacity that rarely cycles can add cost without equivalent value, and standard systems do not necessarily provide backup during a power cut.
