Power Rating of the Excel Power XL4000ii

  • 3.8KW Maximum Watts (The absolute maximum output that your Generator will give you for about 3-5 minutes tops, before overloading)
  • 3.5KW Running Watts (The all-important continuous Rated power that your Generator will comfortably run at to provide power to your chosen equipment, also this is the most relevant value to compare against other models)

This petrol inverter generator is extremely compact and strong with a tough and durable casing, so can be stored with ease in various load spaces. With a generous fuel tank of 10 L, the Excel Power XL4000ii petrol generator is perfect for your workshop or next outing in your caravan or motor home. Plus, its surprisingly light, just 52KG. With an easy-to-use configuration this portable petrol generator gives you a fantastic balance between performance and price.

Do Inverter Generators Have Low Emission Engines?

Not all do but the requirement since 2021 is to have a low emission certified ‘Euro V’ engine – all Excel Power petrol generators are certified to this low emission standard. You can rest assured that this generator has a low impact on our environment.

Is the Excel Power XL4000ii Easy to Start and Use?

You bet it is – Simply push a button and the generator start up (electric start). There is also a remote key fob start function, just click the key fob button to start and stop the generator. The easy recoil start (pull start) is for emergency use which is smooth and silky.  On a well-maintained unit it starts first pull every time – it is engineered to run on the new E10 petrol now available so there are no worries there either.

There are two Uk 3-pin 13A sockets, 1 X 12V DC port and 1 USB port to connect your electrical equipment up to. Also this unit has as an easy-to-read onboard digital display so you can see information such as, hours run, output voltage and frequency. A great feature is the Power Meter which shows you when you are getting close to full load and the fuel gauge so you can see when to refuel at a glance – no more having to stop your generator and open the filler to peer in!

The hours run meter is 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.

Using Sensitive Equipment with the Electrical Power from the Excel Power XL4000ii

The power produced by the Excel Power XL4000ii enables a smooth voltage output, true sinewave inverter technology. It keeps the 230v output clean and stable 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 Excel Power XL4000ii is surprisingly quiet at just 62 dBA @ 7 metres.

Eco Mode on The Excel Power XL4000ii

Fuel consumption can be minimised by the implementation of Eco Mode on the XL4000ii. Simply select Eco Mode and the suitcase generator will lower its revs to increases fuel efficiency and extends the lifespan of the unit.

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. The XL4000ii can be used with E10 petrol.

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.

Specialist Couriers – Some items such as the larger portable power stations are sent by specialist courier as standard couriers will not accept them. These specialist couriers are very reliable but sometimes don’t have tracking or timed delivery.

Split deliveries – We sometimes need to send orders for more than one item by different courier networks (portable power stations for example) – so you may receive items at different times.

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. Pricing for extended shipping areas like Northern Ireland, the Scottish Highlands and outlying Islands, Outer Hebrides, Channel Islands, Isle of Man, Scilly Isles, and other postcodes not considered as UK mainland can be obtained also by calling our offices.

Please note that the processing of a payment and acknowledgement email does not constitute a legally binding contact. In the case of mispricing, changes in stock quantity, or if we believe the machine will be misused, we reserve the right to cancel the order and provide a full refund.

Heavy Items

You will be contacted by phone after ordering a larger item to confirm a delivery date before your order is dispatched. 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.

Heavy items will require the recipient to make arrangements to take delivery of the goods and may require the recipient to help the courier unload the item. For items that are delivered on a pallet the courier will leave the pallet as close to your door as possible.

1500rpm diesel generators will require forklift (or similar) offloading; if this is not available then we can arrange a Hiab offload at an additional price – please call us to discuss any delivery requirements.
