SOROTEC UPS

In the solar power generation system, it is mainly composed of PV module, storage battery, solar controller and load. Although the cost of solar energy controller is only a small part of the PV system, the choice of the controller can optimize the system to a large extent.At present, the popular solar controller on the market is mainly ordinary solar controller, PWM solar controller and MPPT solar controller. Ordinary solar controller is the first generation technology, due to the factors of the internal resistance of battery, it is difficult to charge batteries fully, and solar panels is not fully utilized, the MPPT tracking efficiency is only 70%-76%, so it has been out of the market. PWM solar controller is the most popular used,  solar MPPT controller  is nowadays trend, so more and more people in the industry have to make a choice between PWM solar controller and MPPT solar controller. PWM solar controller is the second generation technology, it use the PWM control mod...

Power supply and distribution system as an important part of the information system, the basic requirement is that the system must be able to work continuously. In order to achieve the purpose of continuous work, the first is that the system should have high reliability, and secondly the system must be able to quickly repair. If it can not be repaired quickly , you may face second failures leading to the risk of paralysis of the entire system, can not guarantee the load continuous work. In terms of rapid repair,  modular UPS  has a natural advantage. First of all, in the repair time, due to the characteristics of quick plug, modular UPS can complete the replacement at the scene, the average repair time in half an hour, compared to the traditional tower UPS for repair time of 24 hours, the repair speed improved significantly. Secondly, in the repair quality, repair the  modular uninterruptible power supply  through the fault module replacement, while the traditiona...

1. Solar power inverter  requires high efficiency. Due to the high price of solar cells, in order to maximize the use of solar cells, improve system efficiency, we must try to improve the efficiency of the solar inverter. 2.Solar inverter requires high reliability. Solar power generation system is mainly used in remote areas, many power station unattended and no maintenance, which requires the inverter with a reasonable circuit structure, strict screening of components, and requires the  solar system inverter  with various protection functions, such as input DC reverse polarity protection, output short circuit protection, overheating protection, overload protection etc.. 3.Solar inverter requires a wide range of DC input voltage. The solar battery terminal voltage varies with load and sunshine intensity, although the voltage of solar cell battery plays an important role, but because of the battery voltage fluctuate varies with the change of residual capacity and inte...

1.Whether  online interactive UPS  in the normal city power supply, or power supply interruption, both power supply from the battery to the  inverter , in the meantime, the power supply to the load is provided by the inverter of the UPS. This basically eliminates the impact of any voltage fluctuations and interference from the city power grid on the load, the realization of the load without interference voltage regulator. At present, the online interactive UPS on the market can achieve regulated power supply to the load, when the voltage range of 180 ~ 250V, the general output voltage stability can reach 220±6.6 V. 2.Online interactive UPS sine wave output waveform distortion coefficient is relatively small. At present, the distortion coefficient of the products sold in the market is less than 3%. 3.When the power supply interruption, the  line interactive UPS system  can achieve the real uninterrupted power supply to the load. UPS manufacturer found that i...

The main difference between  low frequency online UPS  and  high frequency UPS  is reflected in rectifier and transformer. Low frequency UPS rectifier uses SCR, the voltage stress is small and the current stress is high, the high frequency UPS mainly uses the IGBT device, the current stress is small, the voltage stress is big. SCR and IGBT are mature devices, as long as the application is properly, there is no difference in reliability. In fact, the  inverter  part of low frequency UPS is also used of IGBT, and therefore does not reduce the reliability of low frequency UPS, there is no evidence that the inverter is the weak link in the low-frequency UPS. Topologically, low frequency UPS use phase controlled rectifier and full bridge inverter, while high-frequency UPS use high frequency rectifier and half bridge inverter. These topologies are very commonly used in power electronics technology, there is no problem about who is more reliable in principle, its...

The  solar MPPT charge controller , is the automatic control equipment which used in solar power generation system, control multiple solar array to charge the battery and the battery supply power for the solar inverter load. Almost all of the solar power systems that use battery power supply need a solar charging and discharging controller. The function of the  MPPT solar charge controller  is to adjust the power, from the solar panel to the battery. Battery overshoot, at least significantly reduced battery life, the worst damage to the battery is until it can not be used properly. The basic function of the solar energy controller is to control the battery voltage and open the circuit, when the battery voltage rises to a certain extent, stop charging the battery. The old version of the  solar MPPT controller  mechanically to turn on or off the control circuit, stop or start the power delivered to the battery. Solar controllers are used in most PV systems to...
