With an easy-to-use configuration this portable petrol generator gives you a fantastic balance between performance and price.

Is the Stephill SW200AC Easy to Start and Use?

You bet it is – the easy recoil start (pull start) is smooth and silky. On a well-maintained unit it starts first pull every time.

There are 2 x 16A 110V & 2 x 16A 230V BS4343 sockets to connect your electrical equipment up to, along with 3 x DIN 25 welding sockets and voltage selector switch.  Also this unit has low oil shutdown, the generator has a reset circuit breaker overload protection and a voltage selector switch.

Using Sensitive Equipment with the Electrical Power from the Stephill SW200AC

The power produced by the Stephill SW200AC enables a smooth voltage output via the brushless waveform alternator. This keeps the 110/230V output within tolerance making it safe to use with electronic equipment like PC’s, laptops TV’s and more besides.

Low Noise Levels

You might think having a portable petrol generator will be very noisy. Well think again; the SW200AC is surprisingly quiet at 72 dBA @ 7 metres.

What Happens If I Do Not Use My Generator for Long Periods?

As with all petrol engines, if you are planning to store your generator for a long period its ‘best practice’ to either drain the fuel tank then run the generator until it stops. This will prevent any unused fuel congealing and clogging the carburettor. Or to stop the fuel from going off use a petrol additive. Remember, stale fuel can stop your generator from starting when you need it.

Hampshire Generators can also maintain your generator with a regular cost-effective service plan or one-off visit. Simply call 01329 722390 or inquire via contact us page for more information.

When will I receive my order?

In most cases, a product on our website will give you an indication of the current stock availability, but shipping is not uniform for all products. We maintain fantastic relationships with all of our suppliers and we aim to get products to customers within 3 business days of the order being taken. This availability is based on information from our suppliers and from sales and supply patterns. The availability information given is a guide only and not a guarantee as there are external factors that we may not have control over.

Coronavirus Update – UK couriers and transport companies will not currently guarantee delivery times and we are seeing a slight delay in deliveries – please bear this in mind when ordering.

1500rpm machines or larger diesel gensets however are typically priced on application and all depend on the destination. We will be happy to quote on any large diesel generator and discuss your needs over the phone or via email.

Most orders placed before 12pm on a business day will be shipped from our suppliers on the same day provided the product is in stock. If you need to be certain an item is in stock and available, or if you need a lead time, it’s worth calling our sales team on 01329 722390.
