Use more of your own solar
Move suitable surplus generation into evening and peak-price periods.
HOME BATTERIES / SUITABILITY FIRST
Store energy for the
hours that cost more.
A battery can shift solar into the evening, support selected loads in an outage and respond to tariffs or VPP opportunities. The right capacity depends on your load—not the biggest rebate or the largest cabinet.
Check battery suitability
WHAT CHANGES FOR YOU
The practical value.
Define backup properly
Choose the circuits, reserve and power level that matter during an outage.
Manage tariff exposure
Test time-of-use, demand or VPP value without presenting it as guaranteed income.
YOUR OPTIONS
Compare the paths.
Self-consumption
Regular evening demand and sufficient solar surplus.
CHECK BEFORE COMMITTINGDaytime imports, export value and round-trip losses.
Backup
Outages materially affect comfort, work or essential home loads.
CHECK BEFORE COMMITTINGGateway cost, circuit selection, starting currents and reserve settings.
Tariff / VPP
A compatible retailer plan or VPP supports the household objective.
CHECK BEFORE COMMITTINGProgram terms, control rights, event frequency and changing electricity prices.
BEFORE YOU DECIDE
Get the variables clear.
Will a battery save me money?
It may, but the result depends on surplus solar, evening use, tariff spread, battery losses, control strategy, installed cost and how long you keep the property.
How much backup do I get?
Capacity is only one part. Inverter power, gateway, supply phase and the selected circuits determine what can run and for how long.
What rebate applies?
Federal support is certificate-based and depends on eligible equipment, capacity, installation timing and scheme rules. The calculator shows an estimate, not an entitlement.
What the proposal
needs to establish.
- Current federal battery support modelled with eligibility gates
- Tesla, Sigenergy, GoodWe, FoxESS, Fronius and SolarEdge pathways
- Backup hardware treated separately from battery capacity
- Bill-first assessment; no instant-approval claims
QUESTIONS & ANSWERS
The details that matter.
Should I buy now or wait?
Buy when the current economics, backup need and site design work for you—not because of a countdown. Support factors and equipment change, but so do tariffs and installation costs.
Does solar keep working in a blackout?
Ordinary grid-connected solar normally shuts down during an outage. Backup requires compatible battery, inverter, gateway and a deliberately designed backup circuit arrangement.
Can Nexen compare brands?
Yes. The builder preserves customer choice while enforcing same-platform controller and battery compatibility where required.
