When using energy storage products, you should understand what is and what is WH . and the difference between them, so as to safely buy the products that meet your needs. The analysis is as follows.
1. W represents watts in the energy storage power supply. that is, the size of the output power. For example. the output power of 500W means that it can drive devices of less than 500W. and the output power of 1000W means that it can drive devices of less than 1000W.
2. Before using the equipment. we must know the power (W) of the equipment before using it. otherwise it may cause energy storage power protection and cannot be used. At this time. after the equipment is disconnected. the energy storage power supply can be used. If it cannot be started, it can be restored after charging.
3. WH represents watt-hour in the energy storage power supply. that is. the capacity size of storage. For example. for energy storage products with a capacity of 600 WH. the equipment you use is 50W which can use time is about 12 hrs(600 WH / 50 W =12 hrs). For example, for energy storage products with a capacity of 1200 WH. your equipment is 1000W which can use time is about 1.2hrs (1200WH/1000W=1.2hrs). That is to say, the power of the equipment is low the discharge time is relatively long. On the contrary. the discharge time is relatively short when the equipment power is large.

PCBA function declaration
UPS function description
We refer to the dual phase inverter, refers to the product of the motherboard can output inverter and reverse battery charging. It is the use of inverter output LC circuit, input electric supply filtering circuit, and then use the inverter of four full bridge SPWM circuit in the four MOS tubes in the diode for rectification, after filtering at the same time, a high voltage DC is obtained.
In the charging part, four MOS tubes are used to generate PWM waveform, and then a low voltage is obtained through the inverter transformer. After the full bridge rectification, the battery is charged. The functions are shown in the figure.

Domestic many factories are no design capability. they sell back after the PCBA from the outside. return to the factory and then to assemble. after complete test, shipment.
Our factory all PCBA is designed by myself. battery protection board in the making. we design inverter we have our own plan. charging circuit part has its own patent technology. from the design of the PCB to the completion of PCBA. and assembled finished products. with the aging process of three times.
From another factory owners to sell PCBA. from hezekiah sell BMS. and so on. all of the materials are purchased. not design capability. so the price is high. Our actual product shipment price is the cost of their factory. We can earn money is just a PCBA.
We are design company. the original factory. can be customized with different specifications. different requirements of products. custom speed. high success rate.
