What is an inverter?
An inverter is a converter that connects to a sealed lead acid (SLA) battery that is usually connected to a car, a truck or a solar panel. The inverter can connect to the battery either through a car accessory plug or by clipping directly to the battery. A mains powered device can then be plugged directly into the inverter’s AC socket. Inverters vary in capacity and can power devices of up to a specific wattage. Inverters can be split into two categories: pure sinewave and modified sinewave.

What makes this inverter unique?
This inverter connects directly to the car power using the included alligator clips. Its metallic frame is mountable within your vehicle allowing you to position the inverter unobtrusively. The inverter can power a device – even with sensitive electronics – up to 1000W in power, such as a refrigerator, a hair dryer or a halogen oven. It is highly efficient, converting over 85% of its energy into output power. The inverter includes shutdown protection to power down the inverter if the battery power drops below a certain level.

What is the difference between pure sinewave and modified sinewave?
All household mains sockets output a sinewave along the cable to transfer power from the source, such as the battery or socket the product is plugged in to. This product is a pure sinewave inverter which produces the same quality energy as a household mains socket, unlike a modified sinewave inverter which produces an approximation. A pure sinewave inverter can power electronics such as motors, power tools or clocks, including products with more sensitive component parts. Unlike a modified sinewave inverter, there will be no electrical interference using a pure sinewave inverter, improving a user’s experience with this type of product.

Rated 1 out of 5 by from I bought this to use with power tools, as I read that modified sine wave inverters don't work well with power tools. It worked well with a 400W jigsaw and a 500W drill, but interestingly only at full power, if I tried the speed knob on the jigsaw or depressed the trigger gently on the drill the inverter sensed an overload and shut down. It worked very well with a 1000W reciprocating saw as well. It did not work with a 700W microwave oven, then I found out that the over actually draws 1200W, but intermittently, so on average it consumes 700W. However, the inverter failed after a few months, while charging a dustbuster, drawing maybe 5W. I'll see how the warranty works out.

Rated 4 out of 5 by from Inverters of this size often claim to run power tools etc., but beware! Bought this to run a 450 watt mower, which starts up but inverter quickly cuts out and sounds alarm but no overload or over-temperature indication being lit. Needs a soft-start to cope with the start-up peak current (usually five times run current for about 100 mains cycles - i.e., two seconds). Will try to update this when I figure out a practical way to do it that works. Cable is too short to reach the ground from car battery and you need to buy battery clips to attach it this way.

Rated 4 out of 5 by from A good unit These are good units and do the job they are designed for. But beware, some loads require a high peak inrush current at start up which can trip the overload circuit. My unit will run my absorption type fridge and separate freezer, but the unit trips out when the fridge or freezer thermostat initially cuts in. The unit needs a soft start circuit on its input to dampen the initial peak inrush current. I've tried various circuits externally, but it really needs a longer delay on the internal trip circuit to hold off the trip until the surge has passed. The output waveform is a nice clean sinewave at 50Hz and 250 volts. I've been running all my TV's, radios, computers, printers and some light fittings around my house from this unit for over a year with no problems, but not my fridge or freezer.

Rated 4 out of 5 by from A 800w microwave is the MICROWAVE power. The INPUT power is about 1300w!! So you need a 1500w inverter, not a 1000w. Pure sinewave is important for a lot of digital equipment. This is a vast improvement over a modified sine wave version.

Hi I'm trying to work out whether a pure sinewave inverter like this or a modified sinewave inverter is possible to power an 850w baby bottle preparation machine (tommee tippee perfect prep)? I imagine the only moving part is a tiny pump perhaps

Asked by: Engfuser83
An update for those interested, I purchased the modified sinewave 1000W version to try out as it was all my local maplins had in stock and good news, it functions fine. Of course I have only tried it a couple of times so no long term data to give.&nbsp;

Hi I have recently bought one of these inverters. When I don't have anything plunged into it all 3 lights are flashing power temp and overload is this normal. Also it shuts down when I try to use a 800 watt microwave cooker.

Can this inverter safely operate with a battery voltage of 14.4V i.e. run from a battery with a solar charge controller operating at full charge voltage?

Asked by: Andy
Yes, I am pleased to advise the item will support this use.

Do you sell the remote control for this unit &amp; how much ?

Asked by: Luke
On this occasion Maplin do not stock a product that exactly meets your requirements, or indeed anything close enough to offer you as an alternative.

The output frequency is given as 50/60 Hz. How is that selected? From the photos, I can see no means of selecting the frequency. To run UK appliances I expect that the frequency MUST be 50 Hz.

Asked by: Anonymous
I THINK that Dominic is saying that the output frequency is fixed at 50 Hz, which is what I would like from this INV. The rhetorical question then arises &quot;why in the specs is the frequency confusingly shown as 50/60 Hz?&quot;
