Collection: 9 Variable Speed Drives (Solar VSD)
Hybrid Solar VSD Drives – Direct Solar Pumping South Africa
Hybrid Solar VSD Drives for 3-phase pumps & motors in South Africa. Run directly from solar panels + grid/diesel backup. Save up to 100 % on electricity. Nationwide delivery & finance from R1,999/mo.
Energy of Africa’s Hybrid Solar Variable Speed Drives (VSDs) let you run 380 V three-phase borehole pumps, irrigation systems, cold rooms, compressors and industrial motors directly from solar panels – with automatic seamless switching to grid or generator when the sun goes down.
Key advantages
- Zero daytime electricity bills – pure solar pumping
- No batteries required (optional battery input on some models). See our High Voltage Lithium VSD DC Battery Bank listed seperately.
- Soft-start protects pumps & motors (extends equipment life)
- Built-in MPPT for maximum solar harvesting
- Automatic grid/solar/generator change-over
- Remote monitoring via Wi-Fi/4G (selected models)
- Full SANS/IEC compliance & CoC included
Popular applications in South Africa
- Borehole & irrigation pumps (2.2 kW – 455 kW)
- Pivot irrigation & centre-pivot systems
- Cold-room & refrigeration compressors
- Commercial & industrial 3-phase motors
- Municipal & farm water reticulation

Frequently Asked Questions
Do I still need batteries?
No – these VSDs run the pump directly from panels during sunlight and seamlessly blend or switch to grid/generator when solar is low.
Specially developed High Voltage DC batteries optionally available to extend runtimes up to 24 hours from solar power + batteries.
What size panels do I need?
Rule of thumb: 1.3–1.5× motor kW in panels. Example: 11kW pump → 15–18kW panels.
Can it boost low-yield boreholes?
Yes – soft-start and variable speed increase daily yield by up to 40% vs fixed-speed pumps.
