How to choose Off-Grid Low-Frequency Inverter according to electrical appliances and peaks

Many friends ask: How to choose Off-Grid Low-Frequency Inverter for an air conditioner or TV or computer or electric motor? How to match the battery of Off-Grid Low-Frequency Inverter? How long can the Off-Grid Low-Frequency Inverter be used? Wait for these common but difficult questions. Now I will give a detailed explanation of the answers to these questions, and I hope it will play a role in your future purchase of Off-Grid Low-Frequency Inverter.

How to choose a suitable Off-Grid Low-Frequency Inverter To choose a good Off-Grid Low-Frequency Inverter, the first thing to do first is to figure out where the Off-Grid Low-Frequency Inverter is purchased For electrical appliances such as households, they generally face electrical appliances such as TVs, computers, refrigerators, stereos, fluorescent tubes, etc. This type of electrical appliance does not have high requirements for Off-Grid Low-Frequency Inverter, but the voltage stability is comparable to Off-Grid Low. Reasonable configuration of Frequency Inverter power is necessary. So we have to choose the right product for ourselves. We must first understand the continuous power of the off-grid low-frequency inverter, how long we are going to use it, and the peak power of the electrical appliance. The continuous power of Off-Grid Low-Frequency Inverter appliances is the nominal power on our appliances. The planned use time is how much electricity our appliances will consume to complete the work. The peak power is used by the Off-Grid Low-Frequency Inverter at the moment of a startup. What is the impact power of electrical appliances? If we use a battery to power it, the battery is 12V, 36AH, the power it can store is 36x12 = 432W because the Off-Grid Low-Frequency Inverter only has a 95% conversion rate, the battery has 20% of the power capacity that cannot be used, so 432x0.95x0.8 = 328W, which means that on a 36A day, a 12V battery can only provide us with 328W power for one hour, and a 100W TV needs 3600w to work for 36 hours. 36001328 = 10.9. According to theoretical calculations, if we let a 10OW TV work for 36 hours, we need to equip n 12V, 36AH batteries.

We only need to understand: Off-Grid Low-Frequency Inverter can instantly output 2 times the nominal power, Off-Grid Low-Frequency Inverter instantaneous start of capacitive or inductive load 3 to 7 times the peak power. If the Off-Grid Low-Frequency Inverter is determined to be 3 times or 7 times the peak value, it is actually not difficult. Off-Grid Low-Frequency Inverter is 3 times no-load operation, Off-Grid Low-Frequency Inverter is 7 times full-load operation, so what the peak value is, we can judge by the degree of the Off-Grid Low-Frequency Inverter motor drive load.For example, for air conditioners, its Off-Grid Low-Frequency Inverter is purely perceptual, with a large starting peak, because every time the Off-Grid Low-Frequency Inverter compressor starts, the motor works at full load. We can think of its Off-Grid Low-Frequency Inverter startup at 7 times the peak value. 1000w requires an air conditioner with a peak value of 7000W. Off-Grid Low-Frequency Inverter doubles the peak value. 7000W divided by 2 equals 3500W. This means that an air conditioner with a power of 1000W must be equipped with an Off-Grid Low-Frequency Inverter with a power of more than 3500W to start. Today's air conditioners are equipped with Off-Grid Low-Frequency Inverter inverters. 1000w inverter air conditioners must be equipped with a 2000W Off-Grid Low-Frequency Inverter to operate safely. So with a 1000w air conditioner, we can choose Off-Grid Low-Frequency Inverter between 1500W and 2000w.

 

The above is the choice of an off-grid low-frequency inverter, you can choose according to your needs. If you have any questions, please contact SHENZHEN SUNRAY POWER CO., LTD, hoping to help you purchase off-grid low-frequency inverters in the future.
