Our client approached us with two main objectives: to eliminate load shedding and reduce reliance on grid power. We designed a multi-phase project that would adapt to their evolving needs, offering both functionality and aesthetic appeal for their home.

In Phase 1, we began with a small 15kWh/day PV generator, initially using six 415W panels, paired with a 3kVA inverter and a 3.5kWh battery backup. This setup achieved a substantial 50% reduction in grid consumption. In Phase 2, we expanded their storage by adding another 3.5kWh battery, reducing grid reliance by an additional 10-15% and doubling the backup duration during load-shedding.

As the project progressed, we saw an opportunity to optimize the PV system further. Wanting to expand beyond six panels, we recognized that new panels would differ in size from the original ones. To maintain a cohesive and elegant look for the property, we bought back the six initial panels and replaced them with nine 540W panels, ensuring the system met the estate’s aesthetic standards.

In Phase 4, we upgraded the inverter from 3kVA to 5kVA and added a third battery, enhancing both capacity and backup coverage. This final phase completed a versatile, reliable power system that balances robust functionality with refined design, delivering uninterrupted energy and a seamless integration with the home’s surroundings.
