1 Single Phase Inverter – Power Management & EEG Set-Up

1.1 Introduction

This standard operating procedure (SOP) details the steps that are required to successfully activate
and deactivate the Power Management & EEG settings from the front LCD of a Zeversolar single phase
inverter. Typically the Power Management settings on the inverter is required when using a ComBox,
ZeverCom or ZeverManager whilst the EEG setting is for use in Germany. Please note for firmware

versions that are older than the versions listed in Table 2 no Power Management or EEG Set-Up is
necessary.

1.2 Assumed Knowledge

This guide assumes the following:

 A Zeversolar single phase inverter has been installed;
 Either a Zevercom or Zevermanager has been installed for Active Power Management

(optional);

 The installation manuals for both the inverter, Zevercom and/or Zevermanager has been read

and fully understood.

1.3 IMPORTANT – CHECK GRID CODE SETTING DURING COMMISSIONING!

The grid code, power management and EEG settings should be checked during the commissioning of
a PV plant. It is essential to ensure that the correct grid code/safety setting has been selected for the
relevant region. Each Zeversolar inverter is set to a default grid code which is based on the serial
number suffix that can be found on the label affixed to the inverter and its packaging, see Figure 1
below.

Figure 1 - Serial Number with UK Suffix

Inverters shipped to Europe have three distinct suffixes and as such the default grid code is set
accordingly, please see Table 1.

Table 1 - Default Grid Code Settings

Therefore it is necessary to check the serial number suffix and ensure that the correct grid code is
set. For example, an inverter being installed in the UK may have the DE suffix, in this case the inverter
grid code should be changed from the “VDE-AR-N-4105” grid code to the relevant UK grid code “G83/2
or G59/3.” Please contact Zeversolar to receive a copy of the Grid Code set-up guide.

1.4 When is Power Management & EEG Required

Please note: For countries that do not require Power Management then it is recommended that both
the Power Management and EEG settings are deactivated from the front LCD panel.

1.4.1 Power Management

Power management is required when the PV plant requires one or more of the following modes of
operation:

 Ripple Control Mode – this allows the Distributed Network Operator (DNO) to control the

power produced by the PV Plant, via a remote radio ripple control receiver, in defined limits of
PV plant output e.g. 0 %, 30 %, 60 %, 100 % of inverter rating;

 Cos(phi) Fixed Mode – the PV plant will regulate the reactive power according to a fixed

Cos(phi) (Power Factor) value;

 Cos(phi) Variable Mode – the PV plant will regulate the reactive power according to a defined

characteristic which is a function of P/Pn;

 Q Fixed Mode – the PV plant will regulate the reactive power according to a fixed reactive value

which is a percentage of the instantaneous AC power generated by the PV plant;

 Q Variable Mode - The PV plant will regulate the reactive power of according to a defined

characteristic curve which is a function of U/Un;

 Active Power Limitation – The PV plant will limit the active power based on either the rated

inverter AC output, rated DC array power or an export limit.
The modes of operation must be set on the webserver page of either a ComBox, ZeverCom or
ZeverManager, please refer to the ZeverCom or ZeverManager instruction guide.

1.4.1.1 Where is Power Management Required?

Countries include - Germany, Cyprus, Austria. Typically for all other countries, such as the Netherlands
and the UK, please ensure that the Power Management setting is DEACTIVATED, however when in
doubt it is necessary to consult with the relevant DNO in the region to determine what modes of
operation are required.

1.4.2 EEG – 70 %

This setting is required only in Germany as the German Renewable Energy Act (EEG 2012) stipulates
that PV plants up to 30 kWp must operate via the Ripple Control Mode or by limiting the active power
feed-in at the grid connection point to 70 % of the installed PV power (kWp). The latter of these
methods can be achieved by simply activating the EEG setting from the front screen of the inverter
which automatically reduces the inverter AC output to 70 % of its maximum AC rating. For all other

countries please ensure that the EEG setting is DEACTIVATED.

1.7.1 Checking Firmware Version

It is necessary to ensure that the inverter has the appropriate firmware version. For older firmware
versions it is not necessary to deactivate or activate these settings. To check the firmware version of
the single phase inverter please follow the steps outlined in Table 3.

Table 3 - Firmware Version Check

1.7.2 Power Management & EEG Set-Up

Power_Management_1_Phase_Inv_Rev1_20160426 5

1. Navigate to the “Normal” screen by

pressing the control button on the front
panel.

2. When the “Normal” screen is displayed,

press and hold the control button for
approximately 10 seconds.

3. To deactivate the Power Management &

EEG setting, press the control button
repeatedly until “ActiveP&EEG : OFF” is
displayed. To confirm the setting simply
release the control button and wait until
the “Normal” screen is displayed.

4. To activate the Power Management,

press the control button until
“ActiPowFun: ON” is displayed. To
confirm the setting simply release the
control button and wait until the
“Normal” screen is displayed.

5. To activate the EEG setting, press the

control button until “EEG : ON” is
displayed. To confirm the setting simply
release the control button and wait until
the “Normal” screen is displayed.
