1, first look at the overall situation of the company:
Goodway has been focusing on the application of "series photovoltaic inverter" in the distributed field of China. Since the establishment of 20 10, it has maintained a rapid growth momentum, which also benefits from its emphasis on R&D team building. At present, there are more than 120 core technology R&D personnel, and sales and engineering service centers have been set up in China, Australia, Britain and the Netherlands. In short, these years can be said to be devoted to doing inverters, specializing in inverters.
Sanjing was established earlier (2005). I used to be a frequency converter, and later I started to be a solar water pump controller. Gradually, the inverter was started at 20 1 1. At that time, its new energy division was established, and it was a little late to put it on the market on a large scale. As far as the inverter is concerned, it is slightly lagging behind.
2. Product line:
Goodway has developed and produced photovoltaic products such as NS single-phase single channel, D-NS single-phase double channel, SDT, DT three-phase double channel, MT three-phase four channel, HF high-frequency isolation, ES bidirectional energy storage, BP energy storage converter, H-ES energy storage integrated machine, etc. , power coverage 1.0kW to 80kW.. The inverter has complete series and strong selectivity.
Tri-crystal inverter is mainly in Plus series, including single-phase Sununo Plus 1kw-6kw and three-phase Suntrio Plus 4kw-33kw. The power range of the product is slightly narrow, and the maximum power is 33kw. I have seen dozens of kilowatts or more photovoltaic system projects at photovoltaic exhibitions before, and the recommended scheme is to use two or three 33kw inverters as the solution. Slightly single.
3. Core technologies:
Photovoltaic inverters are mainly divided into grid-connected inverters and energy storage inverters. If we want to compare the reliability of inverters, the most direct thing is to look at the service life (involving the selection of components) and the reliability of products. Who is good and who is bad, you will know when you use it. The only thing is that the cycle is longer. In fact, compared with the product technology of photovoltaic circle, we can look at the energy storage inverter with high difficulty coefficient in inverter products from another angle, and its advantages and disadvantages are obvious. As early as 20 12, Goodway began to develop and produce energy storage inverters. Now four or five series of energy storage products have been developed, and the technology is stable and reliable. Sanjing has just started the energy storage inverter. Comparatively speaking, Goodway walked ahead and saw the development direction of photovoltaic utilization in the future.
Above, for reference only! No matter which company it is, it is hoped that it will continue to maintain the craftsman spirit of independent innovation and provide reliable and assured photovoltaic products for the majority of users.
