The Deye SUN-16K-SG01LP1-EU is a single-phase hybrid solar/battery inverter rated at 16kW, designed to manage power flow between solar panels, battery storage, and the grid — used in South Africa primarily to keep a home or business running through load shedding by automatically switching to battery/solar power during an outage. At 16kW it's sized for larger residential installations, small commercial premises, or multi-inverter setups, well beyond a typical single-room backup UPS. Installing and configuring it requires a qualified solar installer, since it needs to be paired with compatible battery banks and PV panel arrays sized to the household's or business's actual load and desired backup duration.
