If the specification is 12-volt battery 50 Ah, we multiplied by 50 Ah 12 volt, battery power output reached 600 watts. If the solar inverter efficiency is 90%, we then multiplied by 90% of 600 watts, 540 watts draw. This means that you can move a piece of the battery output power up to 540 watts of solar inverter. Of course, you can take “one step”type of procurement approach
No matter that the first use his car battery current specifications, and buy a power output of 800 watts of solar inverter. Then, the first battery in this moment the extent permitted use, so in the future for a greater use of the car and then full power.
Finally, solar power inverter do not ask, for example, 100 watts is enough, then you can buy a low-power solar inverters. In addition, in determining when the solar power inverter, there is an important principle, namely, the use of solar power inverter, do not run full term, otherwise it will shorten the life of solar inverter, solar inverter failure while Rate will significantly rise. We strongly recommend that users, preferably not more than 85% of rated power using solar energy inverter state.
How to test solar inverter?
Overload Protection: 150W power inverter solar, open the switch, connected to a load greater than the 160W-180W, solar inverter output will be interrupted refuse 220V power supply, the red light flashes. The scope of protection 300W 300W-350W 500W 500W-550W scope of protection
Low-voltage protection: in the solar system can work for some time, the battery’s power gradually reduced to 10.5V when the solar inverter alarm, sensitive electrical appliances (such as computers), please stop using it. Ignore the alarm voltage down to 9.7V-10.3V solar inverters automatically shut down,Overvoltage Protection: Charging system failure, battery voltage rises to 15.5V or more solar inverter stop working.Short circuit protection: solar inverter work, 220V output short circuit, the red light flashing, and remove.Over temperature protection: in the solar inverter full load after a period of continuous work, the shell body temperature reaches 55-65 degrees and cut off the power when the alarm.
Note: If using solar inverter rated power than a refrigerator, air conditioning to start the solar inverter, can be automatically protected if protection is a real good product.
Why Solar inverter causes noise?
Solar inverter output noise as the load directly affects the work of the electronic equipment of concern. Even if electromagnetic compatibility testing by the solar inverter, in practice may still occur when the noise level exceeds the situation. The main reasons are:
a. Inverter with some of the load parameters change after the filter, filter effects reduced.
b. solar inverter on the output impedance of asymmetrical arms, causing the common mode noise level is not equal to the difference between the change in the differential mode noise. If the power inverter output filter inductor in series with one arm way, some of the rectifier when the load is to ease the impact of closing the current, and in its input side (ie, the output of the inverter side) arm cascaded Choke inductor, making arms impedance becomes asymmetric.
c. When the solar inverter input and output side of the common mode filter circuit ground wire connected to the same point, to form a ground loop, the input side of the common-mode noise through the output side of the common mode filter circuit of the grounding line, the Common-mode noise coupled to the output, even if coupled with an EMI filter is invalid.
d. some of the load bearing switching power supply for the load, it can be transmitted to the switching noise of its input side, that is, the inverter output side.
e. the input and output cables laid in parallel and in close proximity, leading to the input side of the noise coupled to the output line, especially the large-capacity boost inverter input current large, the noise coupling serious.
