The solution is ideal for households with high energy demands or small commercial properties, especially in areas with an unstable grid. This system can easily support multiple high-energy appliances, such as EV charging, underfloor heating, central air conditioning, and water heaters. Notably, the 20.0kWh battery provides Whole House Load support, meaning that even during a power outage, all household electrical devices can continue running without any disruption. In Auckland, this system generates approximately 1,459 kWh per month during winter and up to 2,713 kWh in summer. With smart power management, you can maximize solar energy usage during the day, reduce reliance on the grid, significantly lower electricity bills, and enjoy a clean, reliable energy solution.
