8kW hybrid PV system
A hybrid solar installation sized against the household’s actual load profile rather than roof space alone — prioritising self-consumption over export.
Monitored performance since commissioning shows the system carrying the majority of daytime load, with the balance drawn from grid during low-generation periods.
36kW three-phase hybrid system — The Parkwood Boutique Hotel
A turn-key hybrid solar installation for The Parkwood Boutique Hotel — three 12kW three-phase SUNSYNK inverters, 35.7kWh of LiFePO₄ battery storage, and 24 solar panels, integrated with the site’s existing 80kVA generator and multi-property supply.
Full SANS 10142-1 certified installation across three separate properties on-site, with automatic changeover between grid, solar and generator supply — commissioned and handed over with Certificate of Compliance.
