At the heart of the Inmesol AH-550 petrol generator is the super economical and reliable Honda GX-270 4-Stroke engine. It produces the 4.5kVA of power effortlessly in spheres such as; commercial use, tradesmen or simply home or garage use

Getting the power where you need it has been made easy. There is an optional wheel kit available for the Inmesol AH-300.

Using Sensitive Equipment with The Electrical Power from The Inmesol AH-550

The power produced by the Inmesol AH-550 enables a smooth voltage output via the optional Inmesol AVR alternator. It keeps the 230v output within tolerance making it safe to use with electronic equipment like PC’s, laptops TV’s and more besides. However, the Inmesol AVR alternator is sturdy enough to cope with building site equipment and the power tools and paraphernalia within that industry.

Is the Inmesol AH-550 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 is also available an electric start version which can be purchased via the options.

There are 2 single phase sockets fitted to the Inmesol AH-550 to connect your electrical equipment up to. Also, as an optional extra there is an easy to read onboard display. You can see information such as; hours run, output voltage and frequency. This is important, as you will need to know when your generator will need servicing after the scheduled hours run time has been reached, this will keep your generator maintained and running for thousands of hours use.

What Happens If I Do Not Use My Petrol 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.

Large or heavy items are dispatched through a pallet network, so if we can’t get in contact with you, we may be unable to send out your item on a next day delivery. Please be sure to include a working phone number with your order.
