Photovoltaic Solar Inverter Series ES Electrical Installation
ES series 38
Attention! Danger of material damage
In determining the required panels in the PV string, please take note of
the following points:
To avoid damage to the photovoltaic solar inverter, make sure that
the output on the PV module is never above 500 VDC.
Make sure that the maximum open circuit voltage U
OC
of each PV
string is less than 500 VDC. Voltages of over 500 VDC may damage
the photovoltaic solar inverter.
Make sure that the short circuit current of the module is not greater
than the measurement on the photovoltaic solar inverter.
To achieve the maximum energy output from your PV module, make
sure that the voltage does not fall below 150 VDC at maximum UMP
performance or exceed 450 VDC.
Within one tracker, only modules of the same type with the same power
can be used.
Two strings can be connected with the ES4200 / ES5000 models. Here it
should be ensured that the load on both strings is symmetrical.
This means: One input on the photovoltaic solar inverter can process
50% of the rated power and may be overloaded by a maximum of 10%.
To connect the PV module to the photovoltaic solar inverter, proceed as
follows:
1. Check whether the generator terminals have the correct polarity and do not
exceed the maximum voltage for each string.
2. Connect the positive (+) wire of the PV string 1 to the positive quick
connection terminal on the photovoltaic solar inverter.
3. Connect the negative (-) wire of the PV string 1 to the negative quick
connection terminal on the photovoltaic solar inverter.
Repeat steps 2 and 3 for other PV strings.
