UPS
Computers, hi-fi and microwave ovens consume electricity a lot, so if you're considering, with them on board, you will probably need the inverter.
An inverter is probably one of the first extras most owners for the purchase of their boat, the size. The ability to use 240V equipment when you are on passage or moored away from a shore supply is estimated by many people. At the same time, an inverter is one of the easiest items to install, offersunderstand the basic steps. Inverters range in size from 50 W to 4 kW and can supply most of the items you need now plug into the outlet, but to understand their limits, and for this you need to understand what makes them tick.
They work as an inverter voltage at low current (DC) takes the place of batteries, usually 12 or 24, and turns them into high voltage alternating current (AC) and 110V, 230V or 240V. The procedure is the same as the charger, but in reverse,Combined charger and some models twice, with the same basic electronics inside. First inverter transformers used to intensify the tension, and were heavy, but most models use modern solid-state electronics, is to convert the voltage and current from direct current to alternating current, and consequently lighter.
Power your home network follows a sinusoidal shape with a rounded tip, as the current delegate. But while this waveform can be easily generated by rotating a generator in a streamStation, is much more complex and expensive for the production of electronic waste and more power. Instead many inverters with modified sine wave or quasi-sine wave, which has a flat top and sharp edge. The modified sine wave AC power equipment, but may face a number of items, particularly electronics with internal power supply and digital timers, such as computers, televisions and microwaves. They recently had the internal power supplies for most electronic equipment switch-mode systems changedbetter manage the quality of the incoming AC poorest. At the same time has improved the standard of the best modified sine waves clearly suggests that a pure sine wave.

An inverter is a high performance, but it has all this power to come out of batteries. Short burst high-power devices such as microwave, kettle, toaster and hair dryer are running well, but a heater or machinery for a long time, you need a very large bank of batteries or motorPower.
As we said, virtually everything can now plug into powered by an inverter, but will adjust the size of the device, what will be. They run up to 500W, can the computer, TV, hi-fi, mobile phone chargers and cameras, and even a domestic refrigerator 240V, but not always all at the same time.
Up to 1,000 W, and you can add a small travel hair dryer. For many people, but the big advantage is the ability to run a microwave oven and for this you needat least 1,500 W, preferably 1800 W. Is to be confused by 80OW 60OW or evaluation on most microwave ovens. This is the most useful cooking power they generate, not the amount of energy that will be twice this figure.
And in that size, if your drive is also a hairdryer standards, plus maybe a manufacturer kettle, toaster and coffee, even if this requires 2kW.
The installation of an inverter is available to a qualified electrician do it yourself, but if you have any doubt, leave ita professional. A 2kW, 12V inverter is working on the batteries 200A, more than many starter, you have links with a large diameter cable, short runs, and good. For higher output models, using a line 50mm (35mm for small services), up to 1.5 m with properly crimped ferrules, not screwed, as they dissolve. Anything less and you might too much power down the line, which means reducing the power and potentially losing the unit. You mustsuitable cable from a dealer or battery electric automotive suppliers. Measure the exact length you want before buying. You will probably crimp the connectors for you, but check the diameter of the tunnel. Most batteries will be 8 mm, but the inverter can l0mm.
If you drive further away to be mounted, using the supplied 70mm, or two 35 mm parallel cable for both positive and negative.
If a fuse of the main entrance is already installed, you must install a 250A fuse in the feeder.There is also a good idea to have a special switch of the battery are in line, so you can completely disconnect from the mains. This must be capable of 250A continuous load. Check the size of the connector pins - which usually l0mm.
The DC-input jack on some units were very close to each other, risking a short circuit. If there is no cover with plastic, customize your own.
Your battery bank is an important aspect of assembly is the smallest inverter ... If you take out 200Afully charged 200 Ah bank, the terminal voltage of 12.6 V to 11.0V battery drop the inverter. If the bank pays only half the voltage to 10.5 V, near the lowest point of the network 10,0-10.5 trip voltage V
If you are installing a 21kW inverter, you should have a minimum of 400 Ah batteries, preferably 600Ah. For a 1-kW system, you must 200Ah, 300Ah instead.
All these numbers assume the engine is not running, what is the normal situation, when at anchor.When you start, you will get some input from the alternator and the battery voltage will increase, leading to improve the situation, but you should not rely on it.
The condition of the battery is important. High continuous power drains will hammer the bank, and quickly find the weak cells. Gel or AGM will be better able to handle heavy loads continuously.
The output of the inverter 230 is one or more outputs on the front, or you may needHard-wire cable internally re-do only if you're sure your skills are. UK three-pin plugs are the best side or upside equipped to large plugs or power currently provides basic foul.
Because the inverters have the proximity to the batteries, are usually mounted in the engine compartment, or at least away from the kitchen. But because most of them still continued demand for electricity in standby mode should let you do not need it permanently switched on. ARemote Control Panel, you can disable the inverter if it is not necessary.
Ideally, you should activate a switch setting in the output circuit between the entry cost AC power, generator and inverter. It 'important that you do not have two different power sources feeding the main ring, at the same time. Getting the correct polarity when connecting the DC or you could damage the device
Every piece of electronic equipment is a high short-termOutput, but will be cut quickly, as it heats. The best practice is to use continuous assessment to describe the device. That said, the rating is important intermittently, as some pieces of AC devices, especially those with motors in them, have a start-up surge protection, a short burst of higher power demand.
Most converters a continuous discharge current when switched on, even if you disagree with them. These standby current is 2A at least, sometimes more, within 24 hourscould 50Ah or more drain on the batteries.
Therefore, a remote control is important. Some models have a power saving mode. This sends the unit to sleep, but nothing is connected, and so is when he is needed. The disadvantage is that small streams, as the light of the timer in a microwave oven, will not trigger the device, so that the microwave will not start. Upload your phone is not able to allow inverter, then you still need to activate it manually.
