System Applications
-
Residential Hybrid Systems – Split-load operation with essential and non-essential circuits.
-
Small Commercial Installations – Combine multiple inverters for 3-phase or higher capacity setups.
-
Off-Grid Systems – Fully autonomous with generator backup integration.
-
Zero-Export Self-Consumption – Ideal for grid-restricted environments such as estates or farms.
Installation Guidelines
- Ensure correct string configuration within the MPPT voltage range (125 V–425 V DC).
- Use appropriately rated DC isolators, surge protection and cabling (sized in mm² for both PV and battery circuits).
- Allow minimum clearances of 200 mm around the inverter for ventilation.
- Install by a qualified electrician or PV installer in accordance with SANS 10142 and local authority requirements.
- Connect CT clamp for zero-export control where required.
Environmental and Efficiency Advantages
This Sunsynk hybrid inverter maximises solar self-consumption, reducing grid reliance and monthly Eskom costs. Its smart management system ensures that solar energy is prioritised, batteries are charged efficiently, and the grid is only used when absolutely necessary. The high efficiency (up to 97.6%) ensures minimal energy losses, while the IP65 weatherproof rating makes it suitable for South African conditions—from the Cape’s coastal humidity to the heat of the Karoo.
Included Accessories
