5kVA Dual-Fuel Generator (Petrol or LPG)
R28 738.50 incl. VAT
The 5kVA dual-fuel generator gives you 4kW of usable power on petrol or approximately 3.4kW on LPG, with the ability to switch fuels at any time. At 5kVA, you can run all household load shedding essentials — fridge, lights, microwave, TV, router, and device charging — without approaching the generator’s capacity limits.
During high-stage load shedding when petrol queues stretch around the block, a 19kg LPG cylinder from Builders Warehouse or Afrox keeps you running for 15–20 hours without leaving home.
Safety warning: This generator produces carbon monoxide on both petrol and LPG. Always operate outdoors. Never run in a garage, tent, or enclosed space. Store LPG cylinders outdoors away from heat and naked flames.
Price: R24,990. Contact PowerVault ZA on +27 83 476 8779 for current stock and specifications.

Delivery timelines are estimates. Orders typically arrive within 3–5 business days after payment is confirmed.
Why the 5kVA Dual-Fuel Is the Power User’s Choice
The 5kVA dual-fuel strikes the right balance between power, portability, and fuel economy. It handles every common household load shedding circuit without compromise, and the LPG capability adds a critical insurance layer when petrol supply is disrupted.
A 19kg LPG cylinder at moderate load (approximately 2.5kW draw) runs this generator for approximately 15–20 hours. At R280–R350 for a 19kg refill, the running cost on LPG is approximately R14–R23 per hour — broadly competitive with diesel and significantly more convenient during supply disruptions.
Electric Start and AVR
Most 5kVA dual-fuel models include electric start and AVR voltage regulation. AVR ensures stable output voltage for connected electronics on both fuel types.
Applications
Household load shedding backup for medium to large homes, small businesses that need flexible fuel options during extended outages, rural properties where LPG delivery is more reliable than petrol supply, and camping and outdoor events where LPG is the convenient fuel.
Safety — Carbon Monoxide and LPG
The 5kVA dual-fuel generator produces carbon monoxide on both petrol and LPG and must be operated outdoors at all times. For LPG operation, ensure the regulator and hose are in good condition and check for gas leaks before starting. Store LPG cylinders away from heat sources, direct sunlight, and naked flames. Do not store more than 2 cylinders per dwelling under South African fire regulations.
Frequently Asked Questions
Q: Is there a power difference between petrol and LPG mode?
A: Yes. On LPG, most dual-fuel generators produce approximately 10–15% less power than on petrol. The 5kVA rated on petrol delivers approximately 3.4–3.6kW on LPG — still sufficient for all typical household loads.
Q: Can I use a standard braai gas cylinder?
A: Yes. Standard LPG cylinders (9kg, 14kg, or 19kg) with a standard 30mbar regulator and hose are compatible with most dual-fuel generators. Confirm regulator pressure specifications with PowerVault ZA for the specific model in stock.
