PV installations are usually installed at remote areas, requiring maintenance teams to spend vast amounts of time to travel to the site. Furthermore, if the cause of problem could not be identified during the first visit or if the personnel did not bring the right spare parts or tools, another trip would be needed. This can be extremely time consuming, causing loss of productivity.
With Phoenix Contact’s PV monitoring system, this can help to minimise the downtime as we are able to monitor the PV plant in real time and obtain comprehensive data. Examples of equipment and readings that can be monitored are: inverters, energy meters, weather condition and even down to every string of the PV panel. If there is any anomaly, an alarm notification would be send to personnel via SMS or email. This is made possible by incorporating a 3G/4G router which can also allow access to the system from other parts of the world.

Another reading which has been requested by many owners of solar plants is historical trends with regards to the efficiency of their plant. To store such a large amount of data at the local controller is not a good idea, furthermore security and performance issues which would possibly affect the local controller could arise. By having the data pushed to cloud storage, it is possible to send the entire plant’s data into the cloud. From the cloud’s database, the data can then be re-organised into trends for further analysis. The historical trends are useful for optimising the productivity of the solar energy plant. For example, we could see the amount of energy generated with respect to the weather condition. From these sets of data, we will be able to tell if the PV Panel is generating the expected energy output. Any anomalies in the respective PV Panels can then be identified immediately. With the implementation of such data, the inefficiency of the solar plant would be minimised.

Today, solar technology in the Philippines still revolves around 1000VDC, which is more or less 5 years old already.
However, due to increasing number of foreign investors in Solar projects in the country, this has resulted in a growing demand for the latest developments in Solar technology . With this we had received numerous request from System Integrators, local end users, and electrical contractors for 1500VDC technology.
1500 VDC systems will allows installers to reduce installation time, string size, wire costs etc.
Being a provider for solutions and products in the solar energy area for many years, Phoenix Contact has been keeping abreast on this demand.
The 1500VDC string combiner boxes from Phoenix Contact meet these requirements of collecting and distributing string currents, protecting the individual modules against damage from lightning and surge voltages, and monitoring the performance of the system.
Solar Seminar 2017
We decided to conduct a Solar Seminar featuring Phoenix Contact’s new 1500VDC technology to address this demand. Held recently at Luxent Hotel in Quezon City, Philippines, our speaker highlighted and focused on 1500VDC Technology and its derivative products like our String Combiner box.
If you missed out on our seminar and would like to be informed of future seminars or would like to find out more about Phoenix Contact’s 1500VDC Technology, do leave us your contact using the form below and we will get in touch with you soon.
Photovoltaic (PV) Monitoring System With Visualisation
The Photovoltaic (PV) monitoring system was designed to monitor the performance of the PV panels’ output versus the temperature on the PV panel. There were two different types of PV panels used for monitoring, namely the mono-crystalline and amorphous silicone (Thin Film). The data that was collected were the DC output and the temperature on the PV panels.
The new VAL-MB product family from Phoenix Contact provides powerful and compact protective devices for photovoltaic applications with generator voltages of up to 1500 V DC. The protective devices are specially adapted to DC application requirements and certified by KEMA.
Longer inlet funnels and higher screw shafts provide additional protection against arcing. The product range includes protective devices for generator voltages of 600 V DC, 1000 V DC and 1500 V DC, as type-1/2 lightning current arresters, as well as pure type 2 surge protection devices. Variants are available with or without remote signaling contact. All protective devices have a short-circuit protection of 2000 A and can also be used in high-altitude plants up to 6000 meters in altitude.
The new Solarcheck monitoring system from Phoenix Contact is a new reliable instrument for monitoring string currents in large-scale photovoltaic installations. The easy-to-integrate system detects losses in power caused by dirty or damaged panels. This enables targeted remedial measures to be taken so as to increase system availability and thus revenues.
