Hybrid solar & battery storage
Hybrid solar and batteries: keep the power on in a power cut
For properties with grid or generator power where outages disrupt essential equipment, or where generator running costs are high. Solar and storage work alongside your existing supply.
01 · DaySolar powers the home first; the surplus charges the battery.
02 · EveningAfter sunset the battery takes over — the grid only tops up.
03 · Power cutThe grid goes down: the system switches to battery backup and essential loads stay on.
04 · Grid backWhen the grid returns the system switches back — and at sunrise solar refills the battery.

When a hybrid system makes sense
Frequent outages
Grid supply is available but interruptions affect daily operations or comfort.
Generator-dependent sites
A generator runs for long hours; solar and batteries can take over part of that load.
Essential equipment
Refrigeration, security systems, network equipment, water pumps or other loads that should keep running.
Keep the fridge, pump and Wi-Fi running in a power cut
Back up what matters most, not the whole building. Essential loads go on a backup circuit — we agree the list with you.
Example only — the final list depends on your loads and battery size.
On the backup circuit
- Fridge & freezer
- Lights
- Wi-Fi & network
- Security & CCTV
- Water pump
Usually not backed up
- Aircon
- Water heater
- Oven & cooker
Switchover and monitoring
Switchover
Depends on the inverter and backup wiring — we explain what to expect.
App monitoring
Solar output, battery level and use — where the equipment supports it.
Grid rules
We advise what applies to your setup.
Design variables we work through with you
- Which loads need backup, and for how many hours
- Peak and starting power of those loads
- Daytime vs night-time consumption
- Available roof or ground space for PV
- Battery type and capacity
- How the grid and/or generator connect to the system
- Room for future expansion
- Budget range
What we need to prepare a proposal
You don't need all of this to start — send what you have and we'll ask for the rest.
- Site location (town / area, and whether access is by road, boat, etc.)
- Current power situation: no power, generator, grid with outages, or grid
- List of equipment you want to run, with power ratings (watts) if known
- Hours of use for each item, and whether it runs in the day or at night
- How long backup should last during outages or cloudy periods
- Where the panels and equipment could go — photos of the roof or ground area help
- Budget range (optional) and any plans to add loads later
