220v inverters HS150K3 PV grid-connected inverter manual

With the development of resonant switching power supply , thinking resonant converter is also used in the inverter power supply system , which constitutes a resonant inverter efficiency . Solar power inverters‍ The inverter is the use of a zero voltage or zero-current switching technology in the DC / DC converter , and thus can basically eliminate switching losses , even after more than 1MHz switching frequency when more power efficiency is not significantly reduced. Experiments show that : in the same operating frequency , the resonant conversion loss comparable non-resonant mode conversion was reduced by 30 % to 40 %. Currently, the resonant frequency of the power supply of up to 500kHz to 1MHz.

Also worth noting is that the study of photovoltaic pure sine wave inverter‍ systems with small power inverter is moving in the direction of the development of modular , which uses a combination of different modules , can constitute different voltage waveform conversion system .

Undoubtedly, medium power PV systems will use high-frequency inverter power conversion circuit structure. In some of the technical details , will be different from the power inverter other occasions , such as the addition to the pursuit of high reliability, high efficiency outside , but also for the photovoltaic industry, the characteristics of the control , the inverter effectively combined, ie PV inverter should be designed with overvoltage , undervoltage , short circuit , overheating, reverse polarity protection. This not only reduces the cost of the system, and improve the reliability of DC AC power inverter‍ the system.

220 volt inverter Small power inverter

Small power inverter is one of the independent AC photovoltaic system is an important part of household, the reliability and efficiency of the promotion of photovoltaic systems, energy solar inverters‍ efficient, reduce the cost of essential system? Thus PV experts in various countries have been working to develop suitable for indoor use power inverter, to promote better and faster development of the industry. 

PV systems with small power inverter power inverter power by converting technology can be divided into frequency conversion and high conversion. Frequency transformation is the use of discrete devices or manifold generate 50Hz square wave signal, then the signal is to promote the use of the power switch, the use of frequency step-up transformer produces 220V AC. This power inverter simple structure, reliable operation, but because of defects in the circuit structure itself, not suitable with inductive loads, such as refrigerators, electric fans, water pumps, fluorescent DC AC power inverters‍ lighting. In addition, due to the use of this power inverter frequency transformer, thus bulky, heavy, high price. Currently mainly used in large-scale solar photovoltaic power plants.

220 volt power inverters Principle Power Inverter

Using a thyristor circuit to convert the direct current alternating current, this corresponds to a reverse process of the rectifier, the inverter defined. For example: Application 12v to 240v inverter‍ thyristor electric locomotives, so that when the downhill braking DC motor as a generator to run the locomotive's potential energy into electrical energy, trans go to the AC grid. Another example is the operation of a DC motor, to make it quick braking, the electric motor as a generator also allows operation of the motor kinetic energy into electrical energy, anti-delivered to the grid. 

The inverse DC into AC inverter circuit circuit called. In certain cases, the same set power sinverter‍ of thyristor rectifier circuit not only for, but also as an inverter. 

Converter in the inverter state, if the inverter AC side connected to AC power, the inverter converts DC to AC power with a frequency counter to go, called active inverter. If the change is not the AC side current grid connection, but directly to the load, which is a frequency inverter converts DC or AC adjustable frequency supplied to the load, then called passive inverter. AC frequency converter uses this principle to work. Except for the active inverter DC reversible speed control system, but also for the exchange of spare lines rotor induction motor cascade car inverter‍ control and other aspects of HVDC.

220v inverters Car Inverter Introduction

Car inverter is designed for the production of small mppt solar charge controller‍ electrical appliances inverter, which is currently the most advanced DC - AC conversion of the product. The 12V DC vehicle into a 220V AC provides commonly used, widely used in various electrical equipment, such as: mobile phones, laptops, cameras, camera, razor, air cleaners, current chargers and other electrical appliances. Is a car race, white, field work, travel, mobile office, AC power inverters‍ special vehicles of essential goods, electric vehicle successfully solve problems.

220v inverters Car inverter Precautions

* Some chargers may be due to the converter outlet; 

* This product is DC24V car special, DC AC power inverter‍ do not use in other voltages; 

* This product is a negative ground vehicle specific, positive ground vehicles can not be used; 

* This product is not applicable core transformer for 5W traveling charger. 

* May appear to "recharge" the former charging status indicator flashes red full off, the charging process becomes lit when charging. Red full off. This is a normal phenomenon. Does not affect the quality of any charge. 

* Some of the charger plug is inserted because of the mppt solar charge controller‍ direction that they can not work, this situation is to ask the conversion plug direction, then use.

220 volt inverter Car power converter Cautions

Properly connected in the following order: 

1, start the car engine 

2, plug in the AC powered car (the case of switching off) 

3, open the car AC power switch 

4, plug in electrical split pure sine wave inverter‍ equipment 

5, after use, turn off the car AC power switch 

6, turn off your vehicle engine 

Avoid using vehicle power supply failed, inferior DC AC power inverter‍ products may cause the principal burned car.
