Premium 10kW Smart Home Energy Hub with DC Fast Charging

The Challenge

Modern homes with high energy demands—including electric vehicles and heat pumps—require more than just basic solar panels; they require an integrated ecosystem. This project involved a complex triple-roof layout, meaning the system had to be expertly designed to capture maximum sunlight throughout the day across different orientations. The client's priority was high-density power generation, significant storage capacity, and the ability to charge their EV at speeds usually reserved for public charging stations.

The PAC Solution

To achieve maximum yield from the available roof space, PAC engineers installed 21 ultra-efficient Aiko 485W panels. These were secured using the ValkAce mounting system, chosen for its durability and sleek aesthetic on domestic tiles. Our in-house engineering team handled all roof works, including the meticulous installation of BirdBlocker to ensure the array remains free from debris and nesting birds for years to come.

The "beating heart" of this installation is the SigenStor system. We integrated a 10kW Sigen Single Phase Controller with two 8kW batteries, providing a substantial 16kWh of storage. To manage the home’s transition to off-grid or backup modes, a Sigen Single Phase Gateway was installed. The standout feature, however, is the 25kW Sigen EV DC Charger. Unlike standard 7kW AC home chargers, this DC unit allows the homeowner to utilise their solar energy to fast-charge their vehicle at more than triple the standard speed.

The Results

By combining market-leading panel efficiency with the most advanced AI-driven storage and charging technology available, PAC has provided this homeowner with total energy independence. The triple-roof string layout ensures consistent generation from dawn until dusk, while the 16kWh battery stack handles evening loads with ease. With the 25kW DC charger, the client has effectively brought the power of a commercial "Rapid Charger" directly into their own driveway.
