Ideal For
The 12kW unit is ideal for small-to-medium businesses (offices, light manufacturing, retail), farms with three-phase supply, and large residential estates. With 18kW of solar input, you can install 20–24 solar panels and generate significant daytime energy to cover most of your consumption.
High-Voltage Battery Compatibility
Unlike many smaller inverters limited to 48V batteries, the SUN-12K-SG01HP3 supports high-voltage (HV) battery packs up to 560V. This enables larger battery capacities with fewer battery units, reducing system complexity and cost for commercial installations.
FAQ
What is the payback period for a 12kW three-phase commercial system?
At R28,990 for the inverter plus solar panels and batteries, a typical commercial system (48 panels + 30kWh battery) has a payback period of 3–5 years at current Eskom tariffs — sooner if rates continue rising.
Can it operate fully off-grid?
Yes. With sufficient solar and battery capacity, the SUN-12K-SG01HP3 supports fully off-grid operation — ideal for farms and properties without reliable grid access.
Does Deye have local South African support?
Yes. Deye is one of the best-supported inverter brands in South Africa, with multiple authorised distributors and service centres across major cities.

Had a local installer fit the Deye 12kW Three-Phase Hybrid Inverter SUN-12K-SG01HP3 and the whole job was done in a single day. The unit has been flawless for five months now. Stage 6 outages are no longer a problem for us. Highly recommend both the product and PowerVault as a supplier.
