A reliable connection directly to your photovoltaic system is more crucial than ever before. The daily production, pontial error, faults or warning should be quickly reported back to the user no matter how he is from his solar installation.
To reduce the pontial down-time of the solar inverter, reporting and controlling the installation over the internel is now easy thanks to the network card that operate over the Modbus a high speed and reliable hardwired connection.
By knowing the state of your plant it is possible to optimise the performance, increase the energy yield and take corrective actions if the system encounters any issues.

Modbus Web server is only used for connecting with Energy Meter.
SNMP Box/Card could monitor the inverter through “Intranet” (Internal network). If the inverters will transmit the data through internet then the wifi card/box should be used. An alternative solution for control and monitoring over the web is the SNMP box with RJ45 connection to a classic router. Using the HTPP address the user will be able to access the data logger and real time information online.
Voltacon collected in one place the communication card with Modbus protocol, Wi-Fi cards, Web-servers and the manuals with set up instructions. The products are listed below along with the compatible Voltasol Hybrid inverters made by Voltronic Power in Taiwan.
