Design consideration
Grid-connected storage does not automatically provide backup. Backup requires isolation, transfer equipment and designed circuits.

How the system works together
SYSTEM FLOW / CONCEPT
Understand where power comes from — and where it goes
Explain the solution by operating state, not just equipment. The key questions: how it charges by day, supplies at night, and protects loads during local or citywide outages.
01Solar generation
Serve loads first, charge surplus
02Inverter / PCS / protection
Defines safe transfer
03Site loads
Use power by operating strategy
Day charging
Conceptual flow, not an electrical single-line diagram. Wiring, protection and transfer performance require project design and testing.Day: solar serves loads first; surplus charges storage or exports where permitted.
01Solar PV
Produces electricity as sunlight allows.
02Hybrid inverter
Coordinates solar, batteries and household AC power.
03LFP battery
Stores energy; BMS monitors cells and protection limits.
04EV charger
Charges within vehicle, site and energy limits.
05Home EMS
Monitors flows, backup reserve and schedules.
Functional overview · wiring, protection and equipment follow the project design.
Night: discharge with a reserve
The battery supplies selected demand. Tariff optimisation respects backup reserve; the same energy cannot serve both at once.
Outage: isolate and supply selected circuits
Only a backup-enabled design can do this. Solar charging during outages depends on inverter capability, controls and available battery charge.
kW: simultaneous load
List running power, starting peaks and phase allocation. A monthly bill alone cannot size an inverter.
kWh: required duration
Average backup load × duration gives load-side energy. Account for usable capacity, losses, reserve, temperature and ageing.
Compatibility: new or retrofit
Share existing PV inverter, meter and switchboard details to assess AC/DC coupling, battery communication and space.

Everyday solar & storage Use solar at home during the day and store surplus for the evening. Suits households seeking greater self-consumption and less grid electricity. PV + compatible inverter + battery + metering Grid-connected storage does not automatically provide backup. Backup requires isolation, transfer equipment and designed circuits.
Backup for essential circuits Prioritise lighting, refrigeration, connectivity and selected sockets. Define what must run before deciding how long it should run. Solar-storage + backup transfer + essential-load panel Check motor starting currents and single/three-phase supply. Whole-home backup requires additional power and capacity.
Solar, storage & EV charging Schedule EV charging around solar surplus or tariffs after household demand and backup reserve, with limits on total site demand. Home storage + controllable charger + home energy management Confirm charger protocols, driving schedules and service capacity. Vehicle-to-home is a separate capability requiring verification.

Questions worth asking
Will solar alone work in an outage?
Not necessarily. Conventional grid-tied inverters normally stop during grid failure. Outage supply needs island-capable equipment, isolation protection and a verified backup design.
Can I add batteries later?
It depends on permitted parallel units, expansion windows, firmware and battery matching. Document the expansion path at initial design.
Can I go fully off-grid?
It can be assessed, but requires worst-season generation, prolonged low-solar periods, future loads and backup generation to be modelled. Occasional backup and year-round off-grid operation are different requirements.
