a. Stop
The test stops all ESS operations. This test stops operations, such as PV
generation, battery charge/discharge and energy sales/purchase to/from Grid.
Check whether all operations for display and measurement stop during the test.
b. PV Only
This test also stops the battery process. The remaining energy is sold to Grid. If
the energy for the load is greater than the PV generated energy, the balance is
purchased from Grid. For this test, check whether the measurements by PV
and Grid are correct.
c. Battery Charge
The test forcibly charges the battery set. For a normal charge test, configure
the settings for the target charge energy and SOC using options. Through this
test, check whether the energy measurements for the battery set are correct.
When SOC is 95% or higher, charging does not occur. In this case,
perform the battery discharge test first.
d. Battery Discharge
The test forcibly discharges the battery set. For a normal discharge test,
configure the settings for the target discharge energy and SOC through the
options. Through this test, check whether the energy measurements for the
battery set are correct.
When SOC is within 5%, perform the battery charge test first. If SOC is
too low, the battery life is significantly shortened.
e. Automatic
This test finishes manual tests and automatically starts ESS operations.
To operate the product normally, be sure to perform automatic
conversion.
