Solar & battery system design

Make solar and battery storage work together.

FLO looks at your roof, electricity use and future plans together before deciding how solar and storage should work.

Every property is different. The free survey checks what is possible before you commit to a system.

The answer you need

Why should solar and battery be designed as one system?

The inverter arrangement, export limit, charge windows, backup requirement and future loads affect both technologies. A combined model prevents panel and battery sizes being chosen independently.

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.

01

One data model

Bring generation, consumption, tariffs and future loads onto the same time basis.

02

Electrical architecture

Define inverter topology, phases, protection, metering, backup and cable routes.

03

Operating modes

Set priorities for self-use, tariff charging, export, reserve level and monitoring.

The next step with FLO

Good to know

Questions you may have.

Should battery capacity match solar capacity?+

There is no fixed ratio. Capacity should match surplus timing, evening demand, tariff strategy and the battery's usable power and energy limits.

Can the design allow for later expansion?+

Sometimes. Confirm compatibility, connection capacity, physical space and whether later changes affect warranty or certification.

Is an export limit a problem?+

It changes the design and value model but may be managed through inverter settings, storage or load control where accepted by the network operator.

What might change the recommendation?+

Annual totals alone can hide timing mismatch. The design should show representative days and seasons, plus what happens when the battery is full, empty or power-limited.
