1500W 12VDC to 230VAC Pure Sine Wave Inverter - Electrically Isolated


Ask a Question

This pure sine wave inverter is suitable for mobile or permanent power installations. It is capable of providing 1,500W continuously and a 3,000W surge. Ideal for powering microwaves, power tools, TVs, and other power thirsty devices when you are away from mains power. It features a standard 240VAC mains outlet as well as a USB port (2.1A) to charge USB devices. To avoid your 12V battery going flat, a low voltage alarm will alert you when the battery voltage reaches 10.5V, and then shutdown the inverter when the battery reaches 10V. All of the safety features you expect, short circuit protection, overload, low/over voltage, and over temperature. Two built-in cooling fans automatically run when the inverter gets too hot so you can run it for longer in hot conditions. Supplied with heavy duty DC leads and remote control kit.Features:• 1500W AC Output• 3000W max power start for 10 seconds• Greater than 90% Efficiency• Low voltage alarm and shutoff• USB port to charge USB devices

Application Suitability - Inverters

We DO NOT recommend that you use these products to operate the following: FRIDGES, AIR COMPRESSORS, AIR CONDITIONERS An inverter is a device which converts 12 or 24VDC into 240VAC. The240VAC generated is as lethal as the power in homes, and should be treated with the same respect. Inverters can be easily damaged, and connecting the input voltage terminals the wrong way around on the battery can damage the unit - be careful!!• Appliances most suitable for connection include: Most power tools, lights, most TVs, video recorders / players, most computers, fax machines and most audio equipment.• Fluorescent lights can give a highly inductive load on start up which can damage inverters. Appliances NOT suitable include:Electric blankets, toasters, hair dryers, irons, radiators and heavy power tools (large angle grinders, circular saws etc.)Inverters will generally drive inductive loads such as electric motors, but only if the startup current is not high. Generally high startup current situations are when the motor is permanently coupled to a load such as a refrigeration or airconditioner compressor (Imagine the compressor at rest just before top dead centre you can easily realise the start up load on the motor!). Many other motors such asin drills, small angle grinders, buffers etc. start up under virtually no load and this is usually OK for the inverter provided the tool is within the inverter rating.It needs to be pointed out that one of the major differences between a domestic power point and inverter is that the source impedance of a power point is very low compared to the inverter. This is why inverters have trouble with appliances with high start up currents and a domestic power point does not. Another thing that must be remembered is the special case of fluorescent lights with ballast chokes in them (by far the most common type).Manufacturers of fluoro lights assume that they are just going to be installed to a normal 240V 50Hz sine wave supply. They are required to supply a product that does not overly distort the mains waveform. They generally comply with this by installing a, say,3.3F non polarised capacitor ac cross the mains/neutral supply inside the housing of the lamp fitting. This is called a power factor correction capacitor. This seems to work OK for a sine wave supply from a low source impedance.When you drive such a device with modified sine wave 240Vpower, different things start to happen. The power factor correction capacitor presents a much greater load to a modified sine wave signal (which is a complex collection of high and low frequencies)than it would if it was a sine wave.The bottom line is to reduce this capacitor to about 0.47?F or take it out completely. Inverters are generally OK then. It is also possible for an inverter to be damaged by the surges in current generated when using standard flourescent starters. This can be prevented by replacing the starter with an electronic starter.
