This project was for a wonderfully compassionate and devout retired couple, whose warmth and kindness made working with them an absolute pleasure. While they’re not fully off-grid, they manage their energy use thoughtfully, manually disconnecting the AC input to rely on their system during load shedding or when grid reliability is low. With all household loads routed through the inverter, essential appliances are prioritized via AC-Out1, while non-essential items run on AC-Out2.

In Phase 1, we installed a 5kW inverter, a 3.7kWh battery, and six 415W PV panels, creating a solid foundation for dependable power. As their needs evolved, Phase 2 brought an additional 7.4kWh battery from the same manufacturer, enhancing their storage capacity and extending backup duration. For Phase 3, we sourced identical 415W panels to expand the PV array, maintaining a cohesive look and ensuring aesthetics remained consistent.

With a love for the outdoors, especially exploring in their 4x4 caravan, this phased, flexible setup allows them to enjoy peace of mind at home, knowing their energy needs are fully covered, no matter the circumstances. This harmonious energy solution perfectly complements their active, outdoor-loving lifestyle, providing resilience and reliability whenever they need it.
