This is a Deye SUN-20K series grid-tied (on-grid) solar inverter rated at 20kVA, designed for three-phase, low-voltage commercial and light-industrial solar installations. Unlike a hybrid inverter, a grid-tied unit feeds solar power directly into the property's grid-connected circuit and shuts down without grid reference — it does not manage battery storage or provide backup power during an outage on its own, so it is not, by itself, a load-shedding backup solution unless paired with separate battery/hybrid equipment. It's aimed at solar installers and businesses in South Africa sizing a mid-size three-phase PV system (roughly a 20-25kW array) to offset grid electricity costs, sold and installed by qualified solar/electrical contractors rather than as a DIY consumer product.
