Guruwatt inverter monitoring and maintenance system is introduced briefly
The thing that operation and maintenance is most dependent on is monitoring. A good photovoltaic monitoring system should be such that when the circuit of the system fails, it will not suffer loss because it is not aware of it, and it will not lose the opportunity because it is helpless. After the PV system design and installation is completed, O&M is the decisive factor. China's PV system has entered the application of large quantities for less than 5 years, and the technology is not mature enough. Most of the employees are also transferred from other industries. There are many human factors. The components and inverters are installed outdoors. They are also affected by the weather and foreign objects such as dust, leaves, and bird droppings. Therefore, the system must be tracked and maintained frequently after installation. This article describes the specific examples of how Guruwatt inverter monitoring and maintenance system and Guruwatt monitoring system can solve the installer's worries. It is understood that there are two forms of photovoltaic power station monitoring: The first is a third-party monitoring platform, such as Amoy, and Miles. The second is the monitoring platform developed by inverter manufacturers. For example, direct Reuter monitoring system. Both have their own advantages: the use of third-party monitoring platform, can monitor the inverters of multiple companies, adapt to the installation company with multiple manufacturers; the monitoring platform developed by the inverter manufacturers can only monitor the inverter of its own company. There are limitations, but the benefits are obvious, the interface is more targeted, the fault handling is faster, and the remote upgrade is more convenient. The monitoring equipment and cloud platform independently developed by Wrightwater are easy to operate and user-friendly. Even people with no experience can register successfully within 5 minutes. You can view the operation status of each inverter through the monitoring system. The interface is user-friendly. More importantly, it is very convenient. The inverter's working status, real-time power, and daily power generation that the customer is most concerned with are placed on the bottom of each inverter. All the data are clear at a glance. The online intelligent customer service system can also provide services on its own initiative. Problems, fault warnings, problem remote diagnosis, and processing functions. Next we look at how Gurvait inverter monitoring and maintenance system helps customers solve problems. First, register an account on your mobile phone, fill out the country name, user name, set a password, and leave a phone and email to facilitate server push messages. The account registered on the mobile phone will be synchronized to the monitoring website. The operation is simple and convenient, and the interface is friendly. Even a person with no experience can register within 5 minutes. In order to facilitate management, an account can set up multiple power stations based on the actual situation. The owner of the I-side is a power station with villages and towns or districts. Currently, there are a total of nine stations, which can be added in the future. There are 5-20 stations below each station. Inverters, each inverter can change the name according to the actual situation, the rest of the boss will mark the power of each inverter. The inverter's working conditions, real-time power, and daily power generation that the customer is most concerned with are placed under each inverter, and if there is a problem with one of the machines at a glance. The figure below shows that there is a 30KW inverter with lower power than 20KW. After checking the input voltage and current of this machine, it is found that the MPPT current of one circuit is obviously low. After observation at the scene, it was found that there are two strings of the inverter will be twigs. Blocked, a part of the tree was trimmed, and the power generated by this inverter immediately returned to normal. There are three types of data collectors: GPRS, WiFi, and LAN (Ethernet). The RS232 interface is connected to the inverter. The LAN needs to be connected to the router through a network cable. The WIFI needs to be connected to the wireless router without any cost. If there is no network at the installation site. , You can use GPRS collector, use a 2G or 3G mobile phone traffic card, the monthly traffic is about 30M, the cost is about 5-10 yuan / month, you can also choose to use Guerva specific data card, 5 years of traffic costs Only costs 240 yuan. After the inverter is installed, if you want to add a new data collector, you only need to use a mobile phone to scan the barcode and solve the problem within 30 seconds. The operation is simple and convenient. On the mobile phone APP, you can view the power generation curve of each station every day, the amount of power generated per day, and the amount of power generated each month. You can also view the operating parameters of each machine on the day, such as PV power, voltage, current, and output. A phase of power can easily find the problem. When a photovoltaic system fails, it first checks the alarm information of the fault inverter, and then finds the corresponding fault handling method according to the information. Most of the problems can be solved on the spot. If you still can not solve, you can choose to ask questions to the customer service, the server-side online customer service will be patient to answer, if it is a system software problem, you can remote online upgrade, if it is inverter hardware issues, online customer service will be the first time to the customer service center, related After the technical engineer diagnoses, he will decide to use the fastest solution for maintenance or replacement. With such an intimate and efficient monitoring system, the cost is not much. It is only necessary to pay for the hardware cost of a data collector. Software costs, server costs, and data maintenance costs are all borne by the manufacturer. Shenzhen Gruitt is one of the few domestic inverter manufacturers that independently research and develop photovoltaic monitoring systems. From the UI interface to the underlying architecture, it has complete intellectual property rights, and can also be customized for different customer needs. It can also provide proactive services, discovery problems, early warning of problems, remote diagnosis of problems and processing functions. Guruwatt Database has over 130,000 PV systems monitored throughout the country. Through analysis of big data, it can also provide customers with many value-added services: 1) Provide customers with installation design, assembly bracket installation angle, azimuth, number of components in series and parallel, component over-provisioning will affect the system power generation, the system can find the local optimal design scheme through big data analysis. 2) When the inverter works normally, the system can automatically analyze the data based on current, power, and power generation to accurately find inefficient components, push messages to users, and provide processing advice, such as whether components need to be replaced or components must be cleaned.
