Some equipment requires a high starting current. Such devices include motor driven equipment. Items such as power drills and compressor fridges require a high starting current to get them moving. This can be up to six times the normal running current and needs to be factored in when specifying the inverter. Of course, you still need to know whether the output of the inverter is a pure sine wave or not. If a pure sine wave is needed you could consider a generator without an inverter built-in. This will probably be cheaper although the frequency might not be as stable. The best advice is to connect directly to the leisure battery via a fuse using clamp type terminals. It is also advisable to keep the DC wiring to the inverter as short as possible to minimise voltage drop, with the associated loss of power. Where long runs are unavoidable you need to compensate by increasing the size of the connecting cables. If in doubt seek professional advice. Sunshine Inverters are supplied with heavy duty leads fitted with terminal rings for easy connectivity to your battery. At its simplest, an inverter could be a DC motor driving an AC generator although such a device is more commonly referred to as a rotary converter. The inverters here all use electronics to achieve the desired result. This eliminates any moving parts while improving both efficiency and reliability. Uses of inverters

Many small inverters (300W and under) come with crocodile clips which are attached to the positive and negative terminals of the battery.e) Reliably powers the following devices that normally won’t work with modified sine wave inverters:

All in all, it is best to choose an inverter with a continuous power rating of at least twice the cooking power of the oven. As 600W is twice the power of the highest power device and the total power of 430W is still within the maximum power rating of the inverter. Of course it will be more ideal to move one step up and choose a 1000W inverter which would allow for additional devices to be powered or added on in the future. Reproducing such a waveform from a steady DC input voltage is not easy or cheap. However, producing something that resembles it is. This is what modified sine wave inverters do.

There are two principal types of inverter output – modified sine wave and pure sine wave. The former may also be referred to as quasi sine wave. These definitions refer to the AC output waveform of the inverter. It is important to choose carefully before you part with your money. Note: Refrigerator or similar to the refrigerator load equipment, need to choose 10 times more power inverter. Most often the start-up load of the appliance or power tool determines whether an inverter has the capability to power it. Pure sine wave inverters should not cause damage but could easily become overloaded and you do not want them charging the leisure battery, especially if that is powering the inverter.Under no circumstances should the output of an inverter ever be connected to the mains supply. The inverter will be damaged and may even catch fire.

Most leisure and marine batteries will provide an ample power supply for 30 to 60 minutes even when the engine is off. Actual time may vary depending on the age and condition of the battery, and the power demand being placed on it by the equipment being operated by the inverter. If you use the inverter while the engine is off, you should start the engine every hour and let it run for 10 minutes to recharge the battery. A lead acid battery rated at 100Ah is good for about 50Ah before it should be recharged. This is calculated over a discharge time of 20 hours. If you discharge it faster you will get less than 50Ah; if more slowly, you will get more. This is an effect known as Peukert’s law and is something to bear in mind when working out what you might be able to run using an inverter. It may be advisable to operate the inverter from an array of 12V batteries of the same type in a"parallel" configuration. Two such batteries will generate twice the Amps/hour of a single battery; three batteries will generate three times the Amps/hour, and so on. This will lengthen the time before your batteries will need to be recharged, giving you a longer time that you can run your appliances. Avoid placing the inverter on or near heating vents, radiators or other sources of heat. Do not place the inverter in direct sunlight. Ideal operating temperature is between 10° and 30°C.A powerful alternator coupled with a lithium battery can power microwave ovens, vacuum cleaners, hairdryers and so on, while the battery itself has a fast recharge rate. While such set ups are, and are likely to remain, expensive, they do point the way forward for mobile power in motorhomes. If you can stretch your budget to a lithium battery, do so. Lithium batteries can be repeatedly discharged down to about 20 per cent of capacity and can be recharged very rapidly.
