1. The diagram of the whole energy storage system by Sermatec:


There are two options to connect PCS with Grid. 1.GPRS, 2. Internet
PCS Remote Monitor include control,adjustment,inspection and connection
Three levels monitor: equipment, station level, Cloud(App ), including:EMS-Access, EMS-Branch,EMS-Cloud(EMS-Express),the diagram belows:


2. Introduction of monitoring configuration

The diagram shows above,equipment monitoring means:EMS-Access, installed in PCS,a intelligent controlling unit base on Linux,deploys 8 inch touchable screen,friendly interface in simple control,supplying Provide real-time data on local devices and batteries. Abundant connections such as:CAN,RS485 supporting Mobus,CAN2.0,IEC104,TCP/IP connected with SCADA system. The main functions are:

Obtains operation data from BMS(batteries,single module,warning)presents in LCD screen;
Obtains  operation data in PCS and presents in screen;can be sourced the history data;
Obtains warning data in PCS and presents in screen;can be searched the history warning data;
Obtains operation records and presents in screen;can be searched historyoperation records;
Local EMS  functions:Count total charing&discharing amount and time,calculateing cost accroding to user's electricity bill,Provide running reports and analysis reports totally;
Accept scheduling commands from systems (such as EMS-Branch, EMS-Cloud, or third-party system);
Upload local device data to a remote system(such as EMS-Branch, EMS-Cloud, or third-party system);
The system operation parameters can be configured, and the data can be exported locally to the U disk or uploaded to the remote system through the network.;
a remote upgrade function;
Built-in backup, peak-valley price, command and custom four intelligent operation modes;
Built-in battery secondary protection and a variety of intelligent charging and discharging strategies;
Can be connected to air conditioners, electricity meters, flooding, intelligent temperature and humidity sensors and the third-party equipment and dry contact signals;

Sometimes, many pcs and monitoring equipment in applicaiton that could be managered by EMS-Branch system,then connected with EMS-Branch or SCADA system. EMS-Branch deployed on a general server,is a WEB server base on Windows Server B/S .Designed with a variety of new technologies, the interface is friendly, easy to operate instability and reliability.MySQL and Oracle databases are compatiable, The main functions:
Be accessed up to 1000 pcs or the third-party PCS;
With access to video surveillance;
access to other system equipment such as photovoltaic, wind power, charging devise..etc.;
Montioring the system by control,adjustment,inspection and connection.
Strategy of Plant-level/PCS-level intelligent economic operation  based on customer load data analysis;
Plant-level/PCS-level load forecasting based on big data;
Multi-dimensional,  professional data analysis reporting system;
Access to our products through a proprietary TCP/IP-based protocol; access to third-party devices;
Provide Mobus, IEC104 and other interfaces based on TCP/IP protocol to access other SCADA systems;
