SUNSYNK-5K-SG03LP1 · Sunsynk
Good to know
- Runs the home from panels, a battery and the grid, and keeps the power on in a power cut when a battery is connected.
- Output 5000 W, surge 10000 W for 10 s.
- Takes up to 6500 W of panels (up to 500 V, 2 MPPT inputs).
- Battery: 48 V (40-60 V), charging up to 120 A.
- NRS 097-2-1 (the South African grid code): stated. Municipalities generally ask for this certificate before you connect a system that can feed the grid.
- Warranty: 5 years (10 years when installed with a Sunsynk battery). Sunsynk publishes a South Africa-specific 'Manufacturer's Warranty T&C's' PDF on sunsynk.org (image-only, terms not machine-read).
