Frequently Asked Questions
"Direct current" (abbreviated as DC), also known as "constant current", is a kind of direct current, which is a type of direct current that does not change in magnitude and direction.，while alternating current (abbreviation as AC) refers to alternating current in which the direction of the current changes periodically with time, and the running average in one cycle is zero. A power inverter is an electronic device that convert DC(Direct Current)battery power to standard AC(Alternating Current)power.
This solar power inverter is extraordinarily designed for home use, which can convert DC 12V/24V of portable power supply to AC 110V/220V/230V and it works for almost all the household electrical resistive appliances such as MP3/MP4 player, cell phone, laptop, emergency light, electric blanket, electric shaver, electric cooker, digital camera, digital video, CD/DVD player, XBOX/PS4 game player, ordinary electric lamps, bulb, fluorescent light, rice cooker, electric iron, desktop computer, graph scope, fax machines, printers, LCD TV, electric fans, cell phone chargers, electric iron , drinking fountain, hair dryer and so on. (Note: Only pure sine wave inverter can run sensitive electric appliances that are including refrigerator, washing machine, microwave oven, induction cooker, electric drill, compressor, air conditioner, mercury lamp, sodium lamp and so on).
Actually, no. This is the only component of a solar energy system that is not absolutely required. However, if you don't use one, you will not have 120 volts AC and will have use battery power alone. This might be acceptable in a small RV or cabin, but most people want to use normal AC appliances.
Two kinds. Pure sine wave and modified sine wave. Pure sine wave inverter could provide high quality AC and carry various loads, while it requires high tech and high cost. Modified sine wave inverter load poorly not carrying inductive load, but the price is moderate.
Pure Sine Wave inverters produce AC power that is similar to power from Public state grid system. Pure sine wave power operates even the most sensitive and sophisticated electronics. We adopt new and imported for important inner components like IGBT and MOSFET. Saving energy; environmental protection;100% security; built-out fuse; portable for your life. Pure sine wave inverter is ideally suited for any electrical systems.
The AC sine wave of a pure sine wave inverter is just as good as the utility company's AC power. A modified sine wave inverter is not as close but is still quite satisfactory in most cases. Certain motor control circuits don't like the modified wave. Modified sine wave inverters are also much less expensive.
If your load is resistive loads, such as bulbs, you can choose a modified wave inverter. But if it is inductive loads and capacitive loads, we recommend using pure sine wave inverter. For example: fans, precision instruments, air conditioner, fridge, coffee machine, computer, and so on. Modified wave can be started with some inductive loads, but effect for load using life, because capacitive loads and inductive loads need high quality power.
Single phase, off-grid and high frequency power inverter.
It refers to the application of electromagnetic induction’s principle, produced by high-power electrical products, such as motor type, compressors, relays, fluorescent lamps, electric stove, refrigerator, air conditioner, energy saving lamps, pumps, etc. These products ’power are far more than the rated power (about 3-7 times) when start. So only pure sine wave inverter is available to them.
Generally speaking, appliances like mobile phones, computers, LCD TVs, incandescent, electric fans, video broadcast, small printers, electric mahjong machines, rice cookers etc. All belong to resistive loads. Our modified sine wave inverters can drive them successfully.
We will usually have a formula to calculate, but it is not hundred percent accurate, because there is also the battery's condition, the old batteries have some loss, so this is only a reference value: Work hours = battery capacity * battery voltage *0.8/load power
Absolutely. Our inverter is designed with a good regulator circuit. You can even check it when measuring the true value by a multimeter. Actually, the output voltage is quite stable. Here we need make an especial explanation: many customers found it is unstable when using conventional multimeter to measure voltage. We can say the operation is incorrect. Ordinary multimeter can only test pure sine waveform and calculate data.
Different types of load demand for power are different. You can view the load power values to determine the size of the inverter. Notice: resistive load: you can choose the same power as the load. Capacitive loads: according to the load, you can choose 2-5 times power. Inductive loads: according to the load, you can choose 4-7 times power.
We usually believe that cables connecting battery terminal to inverter shorter is better. If you are just standard cable should be less than 0.5M but should correspond to the polarity of the batteries and inverter-side outside. If you want to lengthen the distance between battery and inverter, please contact us and we will calculate the recommended cable size and length. Due to long distances using a cable connection, there will be a reduced voltage, which means that the inverter voltage would be far below the battery terminal voltage, this inverter will appear under voltage alarm conditions.
Put the product in a place where is well ventilate, cool, dry and water-proof. Pls do not stress and do not put foreign objects into the inverter. Remember to turn on the inverter before turn on the appliance.
In domestic market, the high and low inverter brands are mixed together. There are many low-cost inverters is actually some assembled small unlicensed workshops, it crudely, to reduce costs and use of substandard components for assembly, there is a very big security risk! In order to protect the pro personal and property safety, please do not covet low price, be sure to choose a reliable inverter!
