UPS Function

UPS Function
The inverter only has straight AC conversion function, also has a maximum limit to carry forward the usefulness and functionality of the solar system maintenance function problems. Summed up the initiative to stop the operation and function of the maximum pure sine wave online ups point tracking control function, anti-alone operation function (and network systems), active voltage regulation function (and network systems), DC detection function (and network systems), the DC ground fault detection function (and network systems). Here brief introductions active operation and shutdown function and maximum power point tracking control function.
An initiative to stop the operation and function of the morning after sunrise, solar radiation intensity gradually strengthen, the output of solar cells also increased, when the tasks required to reach the inverter output power, the initiative to start the operation of the inverter. After entering operation, the inverter output will be at all times the solar cell module custody, only the output power of the solar cell module is greater than the inverter output Offline ups required for the task, the inverter will continue to operate; stop until sunset, even rainy days inverter can operate. When the output of solar modules become smaller, the inverter output is close to 0, the inverter will constitute standby mode.
2, the maximum power output of the solar tracking control function module is included with the intensity of solar radiation and the solar cell module itself temperature (chip temperature) and change. Else because the solar cell module having a voltage drop with the increase of the current characteristics, and thus be able to obtain the best task exists the maximum power point. Changes in the intensity of solar radiation is obviously the best task point is also in transition. Related to these changes, the task has been to make solar modules at maximum power point point, the system always get the maximum power output from the solar components, such restraint is the maximum power point tracking control. Most important feature of solar power inverter system that covers the use of the maximum power point tracking (MPPT) in this

 

UPS is in on-line UPS when power supply is normal

UPS is in on-line pure sine wave online ups when power supply is normal, the power input voltage noise filter removes all the way through the grid frequency interference in order to obtain pure AC is rectified and filtered into the rectifier and converts AC power to DC smoothing, then divided into two, all the way into the charger to charge the battery, and the other way supply inverter, and inverter turn DC into AC 220V, 50Hz supply load.
When utility power outage occurs, AC input has been cut off, the rectifier is no longer working, then the battery discharge the energy delivered to the inverter, and then by the inverter converts DC into AC for load. Therefore, the load, despite the utility has ceased to exist, but this time the load is not interrupted due to electricity outage, you can still operate normally.

UPS string inverters

UPS string inverters
String inverters are now on the international market has become the most popular inverter. String inverters are based on each PV string (1kW-5kW) through an inverter, the DC side with a maximum peak pure sine wave online ups tracking based on a modular concept, in parallel with the AC-side and network
. Many large-scale photovoltaic power plants using string inverters. The advantage is the difference between the modules without strings and impact of shading, while reducing the optimal operating point of PV modules
In the case of the inverter mismatch, thereby increasing the generation capacity. Technically these advantages not only reduces system cost, but also increase the reliability of the system. Meanwhile, in the string between the introduction - the concept of "master-slave", so in the system in a single string of energy can not work a single inverter case, several groups of PV strings together, so that one or several working to produce more Solar panel inverter. The latest concept for several inverters with each other to form a "team" instead of "master - slave" concept, making the reliability of the system one step further.

 

Online offline UPS UPS to the role

Online offline UPS UPS adaptation range is different, change UPS online offline UPS output voltage in the + 10-15% of the general normal computer use voltage. When the city electricity exception or interrupt,telecom ups online offline UPS UPS immediately in the machine battery electric energy supply computer system through the inverter,Uninterrupted power supply soft hardware online offline UPS UPS to maintain the normal operation of computer system and to protect the computer from loss. The classification and characteristics of solar power system for outdoor and UPS UPS power according to the working mode can be divided into online and off-line two categories, online offline UPS UPS according to the output waveform can be divided into square wave and sine wave outputs two.telecom upsUninterrupted power supply Online UPS UPS offline backup online offline UPS UPS power supply in the electric power supply is normal,telecom ups Uninterrupted power supplythe city electricity through the exchange of the bypass channel again after the switch directly to the load power supply,telecom ups inverter machine in a stopped state. The outdoor solar power generation system in the UPS power substantially equivalent to a voltage range of power regulator. Outdoor solar power system and online offline UPS UPS it in addition to the city, pure sine wave online UPS fluctuation of voltage has improved, adverse effects of online UPS offline UPS in voltage frequency instability,Uninterrupted power supply Uninterrupted power supplywaveform distortion as well as from the string into the power grid disturbance basically did not have any improvement.telecom ups Only the solar UPS when the power supply is interrupted or below 170V, pure sine wave online UPS battery to online offline UPS UPS power supply, Uninterrupted power supplyand provides stable, stable frequency AC power to the load.telecom upsUninterrupted power supply Advantages of solar power generation system backup online outdoor UPS off-line UPS power is high efficiency, low noise, Uninterrupted power supplythe price is relatively cheap, solar UPS is mainly applied to city waves moving little,telecom ups online offline UPS UPS on power quality requirements is not high. Online online offline UPS UPS power supply in the electric power supply is normal, the first commercial AC power into DC power supply, Uninterrupted power supplythen the pulse width modulation, filtering, and the DC power to AC power supply, which is usually composed of alternating current through the rectifier and inverter to the load by way of AC power supply. solar UPS and online offline UPS UPS once the power interruption,telecom ups solar UPS immediately replaced by battery with the inverter to provide AC power supply load. Therefore, pure sine wave online UPS for online UPS power supply, under normal circumstances, online offline UPS UPS with or without electricity,Uninterrupted power supply it is always a UPS inverter power supply power to load, thus avoiding all brought by the electric power grid voltage fluctuations and disturbances.
