UPS efficiency solar inverter

UPS efficiency solar inverter
The purpose is to provide safe isolation and power grid at night and fault isolation in the event. The second structure is non-isolated solutions. Wherein, DC voltage of AC voltage output from the boost stage directly. The third innovation topology structure of the high frequency online ups switch and the power diode, and AC to boost production section of functional integration in a special topology, although the conversion efficiency of solar panels is very low, so that the efficiency of the inverter as possible close to 100% is very important. In Germany, mounted on a south-facing roof of 3kW series module with an estimated annual generation 2550 kWh. If the inverter efficiency from 95% to 96% more than a year will be able to generate electricity 25kWh. The use of additional solar module generates this 25kWh costs associated with increased quite an inverter. Because efficiency from 95% to 96% so that the inverter will not double the cost, so the more efficient inverter investment is the inevitable choice. Emerging designs in the most cost-effective way to improve the efficiency of the inverter is a critical design criteria. As for the reliability and cost of the inverter are two other design criteria. Higher efficiency can reduce the temperature fluctuation on the duty cycle, thereby improving reliability, and therefore, these criteria are actually associated with. Use module will improve reliability.

UPS inverter power in the case of access to electricity

UPS inverter power in the case of access to electricity, and every time you open UPS, we heard the sound of the relay repetitive movements, UPS panel, low battery voltage indicator is lit and the buzzer sounding.
According to the above symptoms can be judged: the failure is caused by the battery voltage is too low, leading to an unsuccessful start caused by Home inverter ups. Remove the battery, the first for a balanced charge (charging all batteries in parallel), if we do not succeed, then only replace the batteries.
6, open the mains power supply is normal UPS, inverter operation indicator flashes, the buzzer sounds intermittently,high frequency online ups inverter can only work in the state, can not be converted to electricity working condition.
Failure Analysis: power inverter can not be converted to electricity supply, indicating that the inverter power supply fails to convert part of the electricity supply, we should focus on testing:
- Mains input fuse is damaged;
- If the mains input fuse is good, check the mains rectifier filter circuit output is normal;
- If the mains rectifier filter circuit output is normal, check the mains detection circuit is normal;
- If the mains detection circuit is normal, and then check the inverter power supply is normal to the mains power switch control output.

UPS works in normal electricity mains via surge absorption filter circuit

UPS works in normal electricity mains via surge absorption filter circuit → AC DC converter circuit to convert alternating current circuit → → DC and AC output converter supply the load and charge the battery at the same time; once microprocessor control circuitry to detect to mains interruption immediately discharge circuit → AC → DC converter converts AC power output from the battery and supply load. If UPS microprocessor control circuit detects a fault, then high frequency online ups will jump to borrow from the relay (RELAY) bypass (BYPASS), mains power supply load, and audible warning the user.
Performance
· Sine wave output
Whether in mains mode or battery mode, can be low-distortion sine wave output power for the user to load equipment for the best power protection.
· Zero transfer time
When power cut or re-power, UPS switch between AC mode and battery mode is no conversion time, effectively ensuring the reliability of the load operation.
Input zero line of fire detection
To avoid UPS mains input zero FireWire reverse the machine with zero FireWire reverse detection.
· Bypass output humanity
To prevent users make UPS work in BYPASS MODE not boot, causing electricity interruption, UPS and equipment are abnormal shutdown. ups mains input is normal, the default output without bypass. Must be turned on, will have a normal inverter output.

Application of telecom companies and offline UPS

Telecom and offline UPS: usually in the ups battery state of charge, the offline UPS in power inverter emergency switch to working state, the direct currentchange battery provides for AC output stable, so the backup UPS is also known as the offline UPS. Advantages of UPS backup UPS power line is: high efficiency, low noise, the price is relatively cheap, off-line UPS is mainly applied to city waves moving little, offline UPS on power quality requirements are not high, the telecom company tip: offline UPS more suitable for home use.However,emergency power ups the UPS has a switching time, therefore not suitable for use in power supply can not interrupt the crucial place. But in fact the switching time is very short, the offline UPS generally ranged from 2 to 10 ms, and the switching power supply of computer itself in power should be maintained around 10 milliseconds, so the personal computer system is generally not because theswitching time and problems. high frequency online ups backup UPS generally only a few minutes to tens of minutes of continuous power supply, is mainly lets you havethe time to backup your data, and finish the work as soon as possible, the price is low. The computer application is not too critical, such as individual home users, you can backup with small power UPS.
