What is the difference between the Gentech 3500W and the GP4500IQ 4500W?

The GP4500IQ delivers 4500W peak vs 3500W peak — an extra 1000W of capacity. In real terms this means you can run a microwave at the same time as your other appliances, handle bigger startup surges from appliance motors, and charge your solar battery bank faster. The GP4500IQ is the right choice for larger homes or anyone who wants more headroom.

Is the GP4500IQ compatible with my Sunsynk solar inverter?

Yes. The GP4500IQ produces pure sine wave power, the required input type for all SA solar inverters including Sunsynk, Victron, Deye, Axpert and Voltronic. Combined with the auto start feature, your Sunsynk can automatically start the generator when battery levels drop low.

Can the GP4500IQ run a microwave?

Yes. With 3800W rated output and 4500W peak capacity, the GP4500IQ comfortably handles a microwave up to 900W alongside other running appliances.

How quiet is 58dB?

58dB at 7 metres is near-silent, roughly the volume of a quiet conversation or running dishwasher. The inverter technology automatically reduces engine speed when load is low, making it significantly quieter than conventional generators at 94dB.

Does Build It Hillcrest deliver to Johannesburg, Cape Town and Pretoria?

Yes. Nationwide delivery including Johannesburg, Cape Town, Pretoria, Durban, Bloemfontein, Port Elizabeth, East London, George, Polokwane and Nelspruit. Free delivery over R950.
