Stop Selling Your Solar for Cents and Buying It Back for Dollars
Your solar panels generate most of their energy between 10am and 3pm. Without a battery, that surplus is exported to the grid for 4–8 cents per kWh — while you buy it back at 30–55 cents between 5pm and 10pm.
A properly sized solar battery eliminates that imbalance entirely: it stores your daytime solar surplus and delivers it on demand all evening, overnight, and during a grid outage.
- Use your own solar after dark instead of grid power
- Cut evening peak-tariff costs — the most expensive power you buy
- Keep the lights on during blackouts with automatic backup
- Stack federal and NSW rebates to reduce your investment
- Earn ongoing VPP credits by supporting the grid at peak times
- Every system installed and supported in-house by ECR
Two Market-Leading Systems, Matched to Your Home
ECR installs the Tesla Powerwall 3 for the most capable premium home energy storage, and the GoodWe Lynx Home U for outstanding performance at a more accessible price. Both are eligible for government rebates we manage on your behalf.
Tesla Powerwall 3
The most capable residential battery available in Australia. With a fully integrated solar inverter, 13.5kWh of usable storage and 11.04kW continuous output, the Powerwall 3 can run an entire home — including air conditioning — during a grid outage while charging from your rooftop solar. It is a complete home energy management system, not just a battery.
- 13.5kWh usable capacity per unit — stackable up to 4 units (54kWh)
- 11.04kW continuous power output — runs whole-home loads including AC
- Integrated solar inverter — supports up to 20kW DC solar input
- LFP (lithium iron phosphate) chemistry — safe, stable and long-lasting
- Storm Watch — automatically pre-charges before severe weather
- Seamless grid-outage backup with millisecond switchover
- 10-year warranty with unlimited charge/discharge cycles
- Real-time monitoring via the Tesla app — solar, battery, grid & home
- VPP-enabled — eligible for the NSW VPP Incentive (up to $1,500)
Best for: homeowners wanting the market's most capable system, properties with high evening loads (AC, pool, EV), anyone needing full-home backup, Tesla EV owners, and new builds or major renovations.
GoodWe Lynx Home U Series
GoodWe is the world's largest inverter manufacturer by volume and one of the most trusted names in Australian solar storage. The Lynx Home U delivers a sophisticated, expandable LiFePO4 battery system at a price point that delivers compelling payback — the financial and resilience benefits of storage without the premium Powerwall investment.
- Capacity: 5.4kWh per module — stackable from 5.4kWh up to 32.4kWh
- LiFePO4 (lithium iron phosphate) chemistry — safest, longest-lasting available
- 6,000+ charge cycle life — equivalent to 16+ years of daily cycling
- Compatible with GoodWe hybrid inverters (SBP, EH and ES series)
- IP55-rated — suitable for indoor or sheltered outdoor installation
- Scalable from day one — add capacity as your needs grow
- Real-time monitoring via the SEMS Portal app
- 10-year warranty
- VPP-eligible — compatible with the NSW VPP Incentive program
Best for: homeowners seeking strong battery ROI at an accessible price, properties with existing GoodWe inverters, anyone wanting to start smaller and expand, those prioritising LiFePO4 safety, and small-to-medium businesses.
Tesla Powerwall 3 vs GoodWe Lynx — Which Is Right for You?

| ECR recommendation | Premium homes, full backup, Tesla EV owners | Excellent value, modular expansion, LiFePO4 safety |
How Battery Backup Keeps Your Home Running
Both systems include automatic backup. When the grid goes down, your home switches to battery power within milliseconds — and keeps charging from your solar panels during daylight hours.
1. Store by day
Your panels generate surplus solar between 10am and 3pm. Instead of exporting it for cents, your battery captures and stores it.
2. Power by night
From 5pm onwards your home draws on stored solar instead of expensive peak-tariff grid power — slashing the most costly part of your bill.
3. Stay on in outages
If the grid fails, switchover is automatic and near-instant. The Powerwall 3 runs full-home loads including AC; the GoodWe Lynx powers essential circuits.
Maximise Your Savings — We Handle Every Application
NSW residents can stack two incentive programs. ECR is a CEC-accredited installer and Accredited Certificate Provider, so every rebate you're eligible for is captured and applied directly to your invoice.
- Federal Cheaper Home Batteries Program — approximately $244/kWh off eligible battery installations (tiered post May 2026). For a 13.5kWh Tesla Powerwall 3, that's around $3,300 off.
- NSW VPP Incentive (PDRS BESS2) — up to $1,500 for connecting your battery to an approved Virtual Power Plant. Stacks with the federal rebate.
- Combined savings — $4,000–$5,000+ off a typical battery installation, plus potential ongoing VPP credits.
- ECR processes every rebate on your behalf — nothing left on the table

NSW homeowners can access two stackable incentive programs: (1) The Federal Cheaper Home Batteries Program — approximately $244/kWh off eligible batteries (tiered post May 2026). For a 13.5kWh Tesla Powerwall 3, that's approximately $3,300 off. (2) The NSW VPP Incentive (PDRS BESS2) — up to $1,500 for connecting your battery to a Virtual Power Plant. These can be combined for total savings of $4,000–$5,000+. ECR handles all applications.
Yes. Both the Tesla Powerwall 3 and GoodWe Lynx systems include automatic backup capability. During a grid outage, your home switches to battery power within milliseconds — and continues charging from your solar panels during daylight hours. The Tesla Powerwall 3 can run full home loads including air conditioning; the GoodWe Lynx is best suited to powering essential circuits.
A Virtual Power Plant is a network of home batteries that a grid operator coordinates to supply power during peak demand events. NSW residents can earn up to $1,500 through the state VPP Incentive program by connecting their battery to an approved VPP — and potentially $300–$1,000+ per year in ongoing credits. Participation is voluntary, but financially rewarding. ECR advises on the best VPP for your system and location.
Both the Tesla Powerwall 3 and GoodWe Lynx carry 10-year warranties. The GoodWe's LiFePO4 chemistry is rated for 6,000+ charge cycles — equivalent to 16+ years of daily cycling. Real-world data from Australian installations consistently shows well-maintained LiFePO4 batteries performing beyond their warranty period. Tesla's unlimited cycle warranty is particularly strong for high-cycling households.
