Types and Uses of the Inverter Generator
Types and Uses of the Inverter Generator
Since a long time, I was a 12-volt man on board our trawler, Patricia Ann. Twelve volt DC systems were usually easy, safe, and had their uses. But subsequent to a recent five-day voyage on our boat where we needed to power-up the generator in order to supply power to the 115-volt AC freezer to preserve temperatures I began to think about some other options. We used up over 90 hours on the genset in just five days. It's time for another oil change! Then I thought about installing an inverter for the freezer. What is an inverter? An inverter is an electrical device that converts battery direct current (dc) power to alternating current (ac). There are a lot of possibilities to pick from, where do I start? When you are looking to choose the best power inverter to fit your boat, the options can be confusing. With a lot of choices available it is crucial to comprehend what the variations are so that you can choose the right one for your particular needs. Your main concern will be the power. Inverters are sized by the wattage they can handle. Think about the equipment you'll be running as well as the amps they require. It is also important to consider the amount of them you will be running simultaneously to decide which size of inverter is the mua bán biến tần cũ most suitable for your requirements. You do not want to overload your inverter by putting on a lot of powerful items simultaneously. You'll probably notice that the cost of inverters rises in proportion to the amount of power. You can locate the wattage by studying the manufacturer's sticker on the appliance. If just the amps are displayed, you can use the formula (amps + 120 voltages= wattage) to convert to Watts. The next issue is whether you should purchase an inverter that is true sine wave or an inverter that is modified. True sine inverters are one that can provide you with an excellent current similar to what you get from the power company. A modified sine inverter is at times less pure. Modified sine inverters is designed to provide a cost-effective alternative over the traditional sine inverter. You will discover that even though the pure sine inverter will provide the most efficient electrical flow, it will also be the most expensive. A modified 1800 watt sine inverter will cost you about $350.00. While the modified sine inverter is more affordable, it has its individual difficulties. For the majority of smaller appliances, such as hair dryers, refrigerators, or refrigerators using a modified sine inverter will suffice. But with certain appliances such as plasma TVs, you could be aware of a lack of accuracy. In this situation, a sine inverter could be an ideal solution to make sure that you will get the highest quality output. It is important to be aware that a modified sine inverter can't be upgraded to a genuine sine inverter. You should ensure that you purchase an inverter that is suitable for your boat's needs at the beginning. It is recommended to inquire about overload shut-off indicators or switches on your inverter just in case you overload the inverter; the majority of inverters come with these switches in their standard features. It's also worth it to look into whether the inverter is equipped with thermal and short circuit shut downs to stop such emergencies also. In addition, some inverters come with built-in shutdown features if the battery storage levels reach a specific low point. I chose to install an Xantrex 1800 modified sine inverter that can handle a power output of 1000 watts of continuous load. This inverter has a built-in transfer switch that switches between the shore power and the inverter power. The last issue to consider is the battery bank on the vessel you are going to draw water from. The inverter will be drawing from this battery bank and you must be able to figure out the length of time that your inverter will function before a recharge must be made. Look over your battery and determine the amp hours for them. Amp-hours are amps for time hours. A battery bank with 2 8D batteries would have approximately 580 amp hours. So, I am aware that my freezer draws 2 amps and runs for 20 mins every hour which is about 7 hours per 24-hour period. So the total amp-hours the freezer can use in 24 hours is 14. Therefore, we could run the inverter for around 41 days without recharge, but should we? It's not wise to run batteries all the way all the way to zero. The life of a battery is directly linked to the extent to which the battery's cycle is every time. If a marine battery is discharged to 50% each day, it'll last roughly twice as long when it's cycled to 80percent of discharge every day. If it is cycled at a rate of 10% of discharge it'll last around five times the time as one cycled to fifty percent. This does NOT mean you won't be able to go all the way to 80. However, you'll need to know the size of the volumes. You should plan for an average discharge of roughly 50% to ensure the best capacity vs. price. Furthermore, there's an upper limit to the discharge - batteries that are continuously cycled at 5% or less will by and large not last as long as one cycles down 10 percent. This happens because at especially short cycles, lead dioxide can form on the positive plates. I prefer to cycle my batteries at a rate of 20 percent before recharge. Monitoring your batteries is possible, however I would prefer to use the Trimetric 2025-based monitoring gadget. This electronic gadget permits me to keep track of the battery banks amp-hours use precisely. With some careful planning Inverters can make boating a more pleasant event. Once you've selected the right inverter for your yacht, make sure you have it correctly installed. If you're not confident about working with electricity then it's best to have a specialist do the job for you. So, you can go on your on the right track knowing that you've got everything you need to keep your boat running on sufficient power. We had another trip of four days during this New Year holiday with our new inverter and I am happy to say we only used the generator six hours over the course of four days. Life is good.
