Rooftop solar
InverterManages energy flow
Your home
Surplus → battery · Further surplus → grid
Solar supplies household loads first. Spare generation charges the battery; further surplus can flow to the grid within your export limit.
Bring daytime energy into your evening.
Charged battery
InverterManages energy flow
Your home
Grid supplies any shortfall
Stored energy supplies your home through the inverter. The grid tops up when demand exceeds system output or the battery reaches its reserve.
Keep selected essentials running.
Backup battery

Essential circuits
Grid disconnected for safety
A backup-capable system isolates from the grid and supplies selected circuits. Runtime depends on charge and loads; backup needs suitable equipment and circuit design.

A system chosen around your home.
FoxESS · storage & inverter
Flexible storage. Built around your home.
🔋 Modular, expandable battery systems
Choose storage to suit your household today, with room to plan for changing energy needs. CQ7 uses 6.96kWh modules; the four-module CQ7-L4 provides 27.84kWh. EP11 offers a separate battery pathway. Expansion is checked against the exact inverter, battery configuration and manufacturer requirements.
🛡️ Flexible, durable design
CQ7 combines lithium iron phosphate (LFP) cells, IP65 protection and natural-convection cooling, with a rated 100% depth of discharge. That means flexible indoor or outdoor placement and access to its rated usable storage, subject to installation requirements and system settings. We assess a suitable location and reserve settings for your home.
🏆 Recognised manufacturer. Local support.
FoxESS was named on BloombergNEF’s Q4 2024 Tier 1 energy storage manufacturer list. For your home, we pair that manufacturer platform with SUNNY’s local advice and a clear contact for installation and aftercare.
JinkoSolar · for new solar + battery
More from your roof. Energy for your home.
☀️ High-efficiency solar generation
The JinkoSolar JKM475N-48HL4M-DV combines 475W rated output with 23.77% module efficiency under standard test conditions. We plan the layout around your roof and shading to make good use of the available space.
🛡️ N-type cells. Dual-glass construction.
N-type cell technology and glass on both sides form a durable panel design. Its −0.29%/°C power temperature coefficient describes how output changes as cell temperature rises above test conditions; real generation also depends on sunlight, orientation and shading.
📄 Long-term product and performance cover
The Australian datasheet lists a 25-year product warranty and a 30-year linear power warranty, with 87.4% rated power at year 30. These cover different things: product defects and specified output retention, subject to the manufacturer's warranty terms.

After installation
A clear place to start when you need help.
Contact SUNNY about the system we supplied. Keep your installation address, fault code and app screenshots handy so the issue can be assessed.
1 · Tell us what changed
Call 1300 013 888 or email admin@sunnyenergy.com.au. Let us know when the issue started and whether there was a power or internet outage.
2 · Identify the right next step
Monitoring, equipment and installation issues need different checks. SUNNY coordinates the support pathway, involving the installation team or manufacturer as appropriate.
3 · Understand the scope
Your written proposal and handover documents set out the relevant product and workmanship cover. Coverage, site visits and any chargeable work need assessment; a battery warranty is not a promise that every service is free.
Sizing questions
Asked at almost every kitchen table.
What size battery do I need for my home?
Start with the electricity you use after solar production falls, then check how much surplus solar is available to charge the battery. Household size alone does not establish the right capacity. We compare your bills or interval data, existing solar, phase and backup priorities before recommending a system; a larger battery is not automatically better value.
Is my existing solar compatible with a battery?
Most homes have a workable retrofit path, but not every battery connects directly to every inverter. We check the complete inverter model, phase, metering, PV arrangement and required blackout behaviour before recommending AC coupling, a hybrid inverter change or a broader redesign.
Can the battery power my whole house in a blackout?
Backup is designed per property. Essential circuits are the usual starting point; wider backup may be possible after checking the switchboard, inverter EPS output, battery discharge limits and large-load starting demand. Battery kWh alone does not prove whole-home capability.
Can I start smaller and expand later?
Some modular systems allow later expansion, but this must be checked against the exact battery and inverter combination, supported module count and manufacturer requirements. Tell us about planned EV charging or other new loads before choosing the initial system; later expansion is not automatic.
Do you offer solar and battery packages in Brisbane?
Yes. SUNNY Energy can assess both battery-only retrofits and complete solar-and-battery systems. The written proposal confirms the panel, inverter and battery combination, standard installation inclusions, site-specific work and the applicable rebate rather than relying on a generic package label.
