ESA series can also capture, display, and save the output voltage and current Waveforms and
store them inside the power supply for retrieval and analysis by users.

The output terminal of ESA series can be short-circuited and supports short-circuit test.
According to the technical specifications of photovoltaic power generation grid-connected
inverters, the photovoltaic inverter must have a short-circuit protection function. When a
short-circuit condition on the AC output side is detected, the inverter must automatically
disconnect from the grid. In the PV inverter test, the short-circuit protection function must be
verified to ensure that the photovoltaic inverter can accurately and timely trip protection
when a short-circuit condition occurs. ESA series can also provide software and hardware
support for the short-circuit test of photovoltaic inverters. Users can set parameters on the
GUI software panel according to the standard to simulate various short-circuit faults of the
power grid for meeting the short-circuit test requirements of the inverter.
