Figure 1. EMS Screen Configuration
Real‐time weather data represents weather in the field based on API real‐time weather data; the
battery charge/discharge amount displays the cumulative charge data of the previous and current days .
Photovoltaic generation and transmission amount shows the accumulated charge data of the previous
and current day.
With real‐time equipment status, it is possible to monitor the operating status of air conditioning
and other facilities, and the temperature setting of the air conditioning facility provides a control
function (when an additional sensor is configured).
PCS displays brief PCS status information such as operation status, and voltage and current of the
power converter; BMS displays status information such as battery charge status, remaining life, voltage,
current, temperature, and upper and lower limits of charge/discharge amount.
The current status of the fault history is displayed as the PCS and battery fault history by date,
time, error code, and error name, and more history can be checked via the button to read the fault
history.
