19.89kW Solar & 50kWh Battery Upgrade in Berwick: Future-Proofing for Total Grid Independence
The Challenge
This Berwick homeowner had a 15-year-old 5kW solar system that had reached the end of its useful life. While their current electricity bills were manageable, they were looking decades into the future. Their goal was to completely eliminate their reliance on energy retailers and create a self-sufficient legacy home to eventually pass down to their children. To achieve this, they needed a massive, premium system capable of handling full-house blackout protection and their upcoming plans to fully electrify the property—including swapping gas heating and ovens to electric, and adding a high-draw EV charger.
System Specifications
We fully decommissioned the legacy 5kW system and installed a heavy-duty, ultra-high-capacity hybrid solution designed to power the home through virtually anything.
Solar Array: 39 x 510W Jinko Solar Panels (Total: 19.89 kW)
Inverter: 1x 10kW Sungrow Hybrid Inverter (SH10RS)
Energy Storage: 50kWh Sungrow Battery System (2x SBH250 units)
System Extras: Custom configured for full-house backup. In the event of a grid outage, this massive storage capacity ensures the entire home—not just a few lights—remains fully operational.
The Outcome
With nearly 20kW of premium Jinko solar generation and a massive 50kWh of Sungrow battery storage, this property essentially operates as its own micro-grid. The homeowners have successfully future-proofed the estate, securing the massive energy capacity required to confidently disconnect their gas lines, charge an electric vehicle, and enjoy total energy independence for generations to come.
