FAQ

1¡¢The price of photovoltaic inverter

Small capacity of 1 ~ 10kW PV inverter, the price is about 1.0 ~ 1.5 yuan / W, the greater the capacity is, the price is cheaper, 500kW may be only 0.5 yuan / W, the specific prices refer to inverter manufacturers offer.

2¡¢Why we should choose inverter with full rated power?
Inverter with insufficient power will mislead you to drive the load which with much actual power, so it is easy to burn; although the price of inverter with full rated power is more expensive, it will be better able to protect your appliances and avoid a lot of troubles.
 
There are many inverters with insufficient power on the market, in addition to ask whether they are with sufficient power or not, you should also call the seller to test fact to fact, which is to see whether the inverters are in long time to reach the power on the label.
3¡¢What does a power inverter do, and what can I use one for?

    A power inverter changes DC power from a battery into conventional AC power that you can use to operate all kinds of devices ... electric lights, kitchen appliances, microwaves, power tools, TVs, radios, computers, to name just a few. You just connect the inverter to a battery, and plug your AC devices into the inverter ... and you've got portable power ... whenever and wherever you need it.

    The inverter draws its power from a 12 Volt battery (preferably deep-cycle), or several batteries wired in parallel. The battery will need to be recharged as the power is drawn out of it by the inverter. The battery can be recharged by running the automobile motor, or a gas generator, solar panels, or wind. Or you can use a battery charger plugged into an AC outlet to recharge the battery.
 

4¡¢Can inverter continuous working for 24 hour?

Generally, the Power Equipments should meet the function that 24 hours of uninterrupted work, as long as the load is not loaded. However, in order to extend the service life of the inverter, we recommend that the inverter should be cut off to have a rest after long hours of work.

5¡¢Can i use my computer with an inverter?

Pure sine wave and modified sine wave power inverter output will operate a computer, However, some monitors and laser printers can only be powered by sine wave output.

6¡¢What¡¯s the difference between a 12-Volt and 24-Volt Power Inverter?
The difference is the type of battery you want to run your power inverter on. Most vehicles run off a 12 volt battery. The 24 volt are generally used in large trucks or industrial motors.

7¡¢What¡¯s the difference between Modified Sine Wave Inverter and Pure Sine Wave Inverter?

The difference between Modified Sine Wave Inverter and Pure Sine Wave Inverter is quite great, the mian different is the output waveforms. The circuit diagram of Modified Sine Wave Interver is much simple, and cost is lower for manufacturing; Pure Sine Wave Inverter with the same power, but the peak power is larger, so the lifespan of Pure Sine Wave Inverter is much longer than Modified Sine Wave Inverter, comparatively, the price is higher, so you need to choose the inverter according to your own actual need.

Please check the specifications of our company’s Pure Sine Wave Power Inverter and Modified Sine Wave Power Inverter.

8¡¢How to choose the power inverter?

      You should first define your needs. Then you need to learn about the inverters that are available. Inverter manufacturers print everything you need to know on their specification sheets (commonly called "spec sheets"). 

      In addition, the factors you should consider are application environment, power capacity, safety certification, electromagnetic charging function, standby power consumption etc.,

      At Jinhua Sunrise , we will be happy to help you finding the products that are suitable for you, about pricing and product information. You can send a mail to us  sales@jinhuasunrise.com£¬We'll also answer any questions you might have about your system.

9¡¢What is converting efficiency of your company¡¯s inverter?

      The efficiency of inverter is the ratio of inverter input power and output power. It is one of the indexes for evaluating the performance of the inverter. If a inverter with 100W DC input and 93W AC output, then it’s efficiency is 93%.

      Because the inverter itself needs energy, so the efficiency may not reach 100%, In general, the converting efficiency of inverter is about 90%~93%, and the European standard is 97.2%, but prices are more expensive.

      At present, the efficiency of our 1500W sine wave inverter can reach 93%, and the price is much cheaper than the imported.

      Besides the converting efficiency, select the inverter waveform is also very important. Recommend checking: Select the right Waveform and Capacity of inverter
