Frequently Asked Questions — Gentech 3500W Auto Start Generator South Africa

Is the Gentech 3500W Auto Start Generator in stock?

This generator is currently sold out due to high demand. New stock is on its way from Gentech. Check back on builditshop.co.za for updates on availability.

What is the price of the Gentech 3500W Auto Start Generator?

R9,990 at Build It Hillcrest (builditshop.co.za). Free nationwide delivery applies on orders over R950 once stock is available.

What is 2-wire auto start and how does it work?

The 2-wire auto start connects your Gentech 3500W to your UPS, inverter or automatic transfer switch using a simple 2-wire connection. When your home loses grid power your inverter or transfer switch sends a start signal through the 2 wires and the generator starts automatically. When Eskom power returns it shuts down automatically. No manual intervention is needed.

Which SA inverter brands are compatible with the 2-wire auto start?

The 2-wire auto start works with most major SA inverter and UPS brands, including Sunsynk, Victron Energy, Deye, Axpert and Voltronic, plus most transfer switch systems. We recommend checking your inverter's generator connection specs for compatibility.

What is the difference between the Gentech 3500W with auto start and the standard 3500W?

Both produce identical pure sine wave power output. The key difference is the 2-wire auto start capability. The auto start model can be connected to your inverter or transfer switch to start and stop automatically with your power supply. The standard model requires a manual pull start every time.

Is the Gentech 3500W pure sine wave safe for my solar inverter?

Yes! Solar inverters and hybrid battery systems require pure sine wave input to charge correctly and safely. The Gentech 3500W produces pure sine wave power identical to Eskom mains, so it charges your Sunsynk, Victron, Deye or any other SA inverter brand safely.

How quiet is the Gentech 3500W Inverter Generator?

At 56dB measured at 7 metres this generator is near-silent, roughly the same volume as a quiet conversation or a running dishwasher. This is far quieter than conventional generators at 94dB, which sound like a lawnmower. Inverter technology adjusts engine speed to match power demand.

Can I still start the Gentech 3500W Auto Start manually?

Yes! The generator retains its manual pull-start cord as a backup. Auto start is an additional feature, not a replacement for manual starting. You can start it manually at any time with the pull cord.

Will Build It Hillcrest deliver this generator to Johannesburg, Cape Town and Pretoria once it's back in stock?

Yes! We deliver nationwide, including Johannesburg, Cape Town, Pretoria, Durban, Bloemfontein, Port Elizabeth (Gqeberha), East London, George, Polokwane, Nelspruit, Pietermaritzburg and Richards Bay. Free delivery applies on orders over R950 once stock arrives.

What warranty does the Gentech 3500W Auto Start Generator come with?

Gentech's manufacturer warranty covers defects and workmanship. Build It Hillcrest also offers a 30-day money-back guarantee on all purchases from builditshop.co.za. We are an official authorised Gentech dealer, so your warranty is fully valid.
