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

Is the Gentech 3500W Auto Start Generator in stock?

Yes. It is in stock and ready to ship from builditshop.co.za.

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

R9,990 at Build It Hillcrest. Free delivery on orders over R950.

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

It connects to your UPS, inverter or transfer switch with 2 wires. Power fails, your inverter sends a signal, and the generator starts on its own. Power returns, it shuts down automatically. No manual work needed.

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

Most major brands, including Sunsynk, Victron, Deye, Axpert and Voltronic. Most transfer switches work too. Check your inverter's generator input specs to confirm.

What is the difference between this and the standard 3500W model?

Both give the same pure sine wave power. This model adds 2-wire auto start. It connects to your inverter and runs automatically. The standard model needs a manual pull start every time.

Is the pure sine wave output safe for my solar inverter?

Yes. Solar inverters need pure sine wave power to charge safely. This generator matches Eskom mains quality, so it works with Sunsynk, Victron, Deye and other SA brands.

How quiet is the Gentech 3500W Inverter Generator?

At 56dB it is near-silent, like a quiet conversation or a dishwasher. That is far quieter than conventional generators at 94dB.

Can I still start it manually?

Yes. The pull-start cord is still there as backup. Auto start is an extra feature, not a replacement.

Do you deliver to Johannesburg, Cape Town and Pretoria?

Yes. We deliver nationwide, including Johannesburg, Cape Town, Pretoria, Durban, Bloemfontein, Port Elizabeth, East London, George, Polokwane, Nelspruit, Pietermaritzburg and Richards Bay. Free delivery over R950.
