About this Manual 1. About this Manual This manual contains a detailed description of the ComBox, including precautions, methods of installation and operating instructions. The specifications described in this document apply to the current version of the product. We reserve the right to make changes or update our product to introduce new functions and overall improvements.
ComBox has two versions: ComBox and ComBox WiFi. 2.1 Product Overview The ComBox is an integrated monitoring device, which can be installed inside the inverter, and collects the inverter’s data and events in the PV plant. When an Internet connection is present, the ComBox will upload the collected data to the Solarcloud to facilitate on-line web monitoring and data analysis.
The details information about Scope of Delivery please refer to the ComBox Quick Installation Guide. 2.5 Environment and Attention The ComBox operational ambient temperature is -25 ° C to 75 ° C. 2.6 Safety Symbols Please pay attention to the following safety symbols in the manual: Information Provides information about installation or use.
In order to ensure safety, before assembly, please read the inverter user manual carefully. Assembly is strictly prohibited when the inverter connected to electricity or is in operation. 3.2.2 Assembly For details regarding mounting please refer to the ComBox Quick Installation Guide.
4.1 Connecting via Ethernet The ComBox is connected to the Ethernet by simply connecting the Ethernet cable from the router to the Ethernet port. The connection between the ComBox and the Internet is shown in Fig. 4-1. Fig. 4-1: Network connection The ComBox obtains an IP address from the router via DHCP automatically and displays it on the LCD of the inverter.
Step1: Power on the inverter, which will also power ComBox, and use a mobile device or laptop to search for the wireless access point (AP) of the Combox WiFi. A new AP of ZEVERSOLAR -XXXX is displayed, Select this AP to connect. The password is “zeversolar”.
