Solar Battery Storage for Cairns & the Atherton Tablelands
Adding battery storage turns your solar from a daytime export into 24/7 energy independence. Shorecan specialises in Pytes LV1 batteries for homes and Dyness Stack 100 banks for commercial and off-grid sites — both engineered for FNQ's heat and humidity.
Backup power when the grid drops
Cyclone season takes the grid down for hours or days at a time. With battery + Deye hybrid inverter, your fridge, lights and internet stay on automatically.
10-year, 6,000-cycle warranty
Pytes LV1 carries a 10-year warranty rated at 6,000 cycles — roughly double the throughput of comparable Sigenergy 5 kWh and 8 kWh batteries on the market today.
Real return on investment
Self-consuming your own solar at ~33c/kWh instead of exporting at 8c/kWh typically halves a household power bill. We model the actual ROI on your data before you commit.
Modular and expandable
Start with what you need today and stack more capacity later. Both Pytes and Dyness are modular — no need to scrap the system to upgrade.
We compare every battery on the same metric: Minimum Throughput Energy (MWh) over the warranty period. A Pytes LV1 5 kWh module is warranted for 30 MWh of throughput. A Sigenergy 5 kWh battery is warranted for 15.85 MWh. Same nameplate capacity — nearly double the lifetime energy. That difference is what makes the long-run economics work.
For commercial sites and off-grid systems, we deploy the Dyness Stack 100 series. These deliver high continuous current, scale to 100+ kWh banks, and pair cleanly with three-phase Deye hybrid inverters — the same platform we use for dairy farms and motels across the Atherton Tablelands.

Frequently asked questions
How big a battery do I need?
For most FNQ homes, 10–15 kWh of usable storage covers overnight load plus a buffer for cloudy days. We size from your actual interval data (or estimate from recent bills) so you don't over-spend or run flat at 3am.
Will the battery power my whole house in a blackout?
Most installs back up essential circuits — fridge, lights, internet, key power points — rather than the entire house, so the battery lasts through a multi-day outage. Whole-home backup is possible with larger battery banks; we'll quote both options.
Pytes LV1 vs Sigenergy — what's the real difference?
Both work. The difference is warranty throughput: Pytes LV1 is rated to 6,000 cycles / 30 MWh per 5 kWh module. Sigenergy 5 kWh is rated to ~3,048 cycles / 15.85 MWh. Over 10 years, the Pytes is engineered to deliver substantially more lifetime energy.
Can I retrofit a battery to my existing solar?
Yes, in two ways: an AC-coupled battery alongside your current inverter, or a full replacement to a Deye hybrid. AC-coupling is faster; replacing the inverter usually delivers better economics over 10+ years. We'll cost both.
