What is the line interactive ups?

The line interactive UPS power supply is also called a 3-port UPS power supply, with a IGBT low frequency transformer inside. From the perspective of energy transfer, there are three energy flow ports in the transformer: port 1 is connected to the mains input; port 2 is connected to the battery through the bidirectional converter; port 3 is output. When the utility power is supplied, the AC power flows into the transformer through the port 1, and the appropriate transformer tap is choosed under the control of the voltage stabilizing circuit, and the output on the port 3 is jointly adjusted by the energy conversion of the battery under the action of the bidirectional converter of the port 2. The voltage is used to achieve a better voltage regulation effect; when the mains is powered down, the battery supplies power to the transformer through the bidirectional converter via port 2, maintaining the AC output on port 3. line interactive UPS power supply In the process of transformer tap switching, the bidirectional converter works as an inverter. The battery is powered, so that the output voltage can be uninterrupted, and there is no conversion time in the switching process from the mains supply to the battery supply. The circuit of the line interactive UPS power supply is simple to implement, and there is no separate charger, which brings about a reduction in production cost and an increase in reliability. Such products do not have AC/DC, DC/AC conversion when the utility power supply works, which improves the efficiency of the whole machine. The line interactive UPS combines many of the advantages of a backup UPS and an online UPS, and is a very good form of transformation. However, because it uses a power frequency transformer, it also has the problem of being bulky and bulky.

line interactive UPS features:
With bidirectional converter design, UPS battery recharge time is shorter;
Have the transfer time
The control structure is complex and the cost is higher than the high frequency online ups.
Protection performance is between on-line and off-line UPS, and it has poor ability to suppress mains noise and surge

Baykee have two type of line interactive ups: one is from 1kva to 6kva, without battery inside. The other one is from 600va to 5kva. Besides the line interactive ups,Baykee also supply online ups, outdoor ups, off line ups, EPS(emergency power source), Modular ups, suit for different need and area. welcome to visit our web www.baykee.com or www.upsindustry.com 

How to choose a suitable MPPT solar charger controller for your solar PV system?

The MPPT solar controller detects the solar panel's generated voltage in real time and tracks the highest voltage and current value (VI), allowing the system to charge the battery with maximum power output. It is the brain of photovoltaic system used in solar photovoltaic systems to coordinate the work of solar panels, batteries and loads.

The Maximum Power Point Tracking (MPPT) system is an electrical system that enables the photovoltaic panel to output more power by adjusting the working state of the electrical module. The DC power generated by the solar panel can be effectively stored in the battery. It can effectively solve the living and industrial electricity consumption in remote areas and tourist areas that cannot be covered by conventional power grids, and does not cause environmental pollution.

The output power of a photovoltaic cell is related to the operating voltage of the MPPT controller. Only when operating at the most suitable voltage will its output power have a unique maximum.

Pulse Width Modulation (PWM) refers to the use of the digital output of a microprocessor to control an analog circuit. It is a method of digitally encoding the level of an analog signal. Digitally controlling analog circuits can significantly reduce system cost and power consumption. PWM controllers are included in many micro controllers.

Both of MPPT solar charger controller and PWM solar charger controller used in the off grid solar inverter system, the main function is to charge and recharge the battery, MPPT performs much better, its efficiency reach 98% or more, and track the peak power of the solar panel, and then extremely take use of the solar energy power.

How to choose a reliable and suitable MPPT solar charger controller for your solar PV system?
Solar charge controller China manufactures focus on the solar inverter business for many years, the mppt solar charger controller developed from the PWM solar charger controller, has a great improvement in the technology and design. More suitable for the various need of market. Firstly, you need to know the voltage of your hybrid solar inverter, and battery voltage, then need get a accurate quantity of solar pv panels, then ask for engineer’s help choose a suitable type mppt solar charger controller for your off grid solar system. Secondly, make a competition about those mppt solar charger controller manufactures, so can choose a reliable manufactures for you. Among all the supplier, the price of the solar charger controller cannot be the only judgment standard, its technology and reliability is also very important. At last, need to mention that, baykee’s Mppt SOLAR CHARGER CONTROLLER,  from 48v50a to 384v100a, have nearly 11 years experience, besides, we have many successful solar pv system project overseas, Australia, Pakistan, India, Philippines, Nigeria and so on.

What is the regular and popular ups capacity in the Market?

UPS or called uninterrupted power supply, now is very widely used in Telcom, Metro, Railway, Manufacturing, Industrial, Hospital, and large smart Building. Among them, based on our calculation and orders before, we have some very hot sale model, even, our factory have arranged many stocks in case of the large demand. For example, the railway and metro industry is one of very hot field for our company, our branch office around the all the cities every year, have millions dollars orders, at one time place 300pcs or more EPS(emergency power supply), 1kva to 10kva, 3 phase high capacity ups, from 100kva to 500kva, some modular ups even can reach to 1000kva. So For those orders, we always have rich stock, it reduce the delivery time and make sure each ups or eps with high quality.

Besides, our ups also have the best prices. When compared with other supplier in China, you may think why our price is high, actually as an old saying: the higher the price, the better the quality; We use the brand known infini IGBT to make sure the high efficiency of the transformer, and keep the safety use of the UPS. Besides, our breaker and switch all choose DELIXI or ABB, to guard the safety of the input and output. What is more important, we Baykee offer the 7*24hours online service, can solve the problem and make you no worries when use our ups. Whatever, Baykee is very brand known company in China, we have 11 years experience in UPS and inverter, you can also have a credit investigate about our company, can know that we are trustworthy and reliable. Baykee’s ups and solar inverter is reliable, cost-effective and can bring more and more profits for you.

What is the using life time of the ups and EPS?
When purchasing the ups, our clients are all worry about the using lifetime about them. For the ups, now it is very mature products, with familiar technology and art, designed to be used for 5-10 years. But every products need to maintenance timely, so for this special machine, our engineer suggest to check the operation of the ups timely, included the wire, cables, terminators, battery, battery connectors, so can find the questions on time, can reduce any loss for it. When used more then 6 years, we suggest to reply the battery even the whole ups system.The new ups system have higher efficiency and more function than the old one.
