personal injuries and/or property damage. These instructions must be complied with
at all times.
If you are not able to understand the language used in this documentation sufficiently,
please contact and inform the supplier of the situation.
Do not try to attempt to install or put the GridManager with FEED-IN function into
service until you have read through all the documentation supplied thoroughly.
Solutronic Energy shall accept no liability for damages resulting from non-observance
of the warnings given in this User Manual.
If you sell on, hire out or pass on this device to someone else in some other way,
make sure that you give the new user these safety instructions, too. Trouble-free and
safe operation of the GridManager with FEED-IN function presumes proper,
professional and workmanlike transportation, storage, mounting and installation as
well as careful operation and thorough maintenance.
3.2 Intended use
This device must be used only for the purpose described in this User Manual:
accessory for use in grid-connected photovoltaic installations.
All safety regulations must be complied with. All installation work must be carried out
precisely as described in this manual. No modification of any kind to or in this device

Prerequisites

GM_User Manual_A8_EN6/28
The energy provider requires a temporary power reduction of the installation:
The inverters are regulated to produce no more power than the current allowed
amount plus the current consumption.
The connected power is generally limited: The inverters are regulated to produce
no more power than the allowed amount plus the current consumption.
There is no feed in allowed / required: The inverters are regulated to produce no
more power than the current consumption minus a small margin for regulation.
5 Mode of Operation
The GridManager covers the power management of the inverter as a function of local
consumption.
It’s located between the SOLPLUS inverters and appliances; and the power meter.
The typical reaction time for power regulation is 4 Milliseconds.
If e.g. a maximum of 70% of the installed DC power may be fed in but refrigerator,
lights etc. are switched on. The consumption of these is added to the 70% and allows
the inverter to produce more power to compensate for this.
Potential uses for GridManager:
Mode of Operation

GM_User Manual_A8_EN 7/28
6 Installation GridManager 63
Connection
3x 230 Volt, N, PE, 50 Hertz, max. 63 Ampere per Phase
It shall be installed between the meter (reference counter when feed in is zero
or bidirectional meter when grid-feed is limited) and the local distribution for
appliances and PV-inverter
You may install either a GridManager or a PowerReductionCard, installing both
at the same installation will not work.
Connect appliances to the same phase as the inverter, especially if only one
inverter is used.
Installation
AC-voltage measurement and power supply
The grid voltages L1, L2 and L3 and neutral line N are connected to the green
4-pin connector at the bottom side. L3 and N (230 V AC, 50 Hz) are used to
supply the GridManager. Wire cross-section 1,5 mm².
Check for correct phasing
For overall one phase operation connect the one phase used to all 3 pins L1,
L2 and L3 of the 4-pin connector for voltage measurement. This can be
achieved by bridging all 3 pins.
For correct display of the measured voltages connect ground to the GridMan-
ager. This is best done on the shield of the Ethernet connector. However, the
GridManager will regulate fine without ground connected.
AC-current measurement
The power lines have to be separated on terminals and routed from the
bottom-up through the current transformers of the GridManager.

8 Connecting GridManager, inverters and PC
All devices are connected using a standard ethernet-switch and -cables.
The GridManager itself has no display. In the first 60 seconds after starting up the
GridManager uses always the IP-address 192.168.0.98. If a connection to this address
is established, the GridManager will continue to use this IP-address, otherwise it will
switch to the set IP-address after these 60 seconds.

SOLPLUS+ and it’s manuals are available on our homepage www.solutronic-en-
ergy.de. Please use the latest version available, at least the version stated in
chapter 4. To setup the GridManager you’ll need the professional version of
SOLPLUS+. If you need a professional key, please contact our service.
Note
In“Administration” of SPLPLUS+you may add the GridManager like a inverter in a
plant using“TCP/IP individual” as connection type.
For the first setup set your PC to the IP-address 192.168.0.10 and use this data in
SOLPLUS+ to create a new inverter (=GridManager):
(Default) IP-address: 192.168.0.98
SPP-Address (=Serial number): see the silver serial sticker on the GridManager

11.2 Total AC power of connected inverters
These parameters define how much inverter AC power is connected to the 3 phases L1,
L2 and L3.
Add up the maximum output of all connected inverters. Maximum parameter value is
320000 W. If one phase is not connected to a inverter enter 0 (zero) on this phase.
The 4th segment of the IP address using the format xxx.xxx.xxx. 98
To use DHCP enter 0 (zero) in all 4 parameters 110-113. The GridManager will receive
a IP-address from the DHCP server. If no DHCP server is present the default
IP-address 192.168.0.98 is used.
However. for use with SOLPLUS+ we suggest using a fixed IP-address to avoid
changes in the administration.
(Not changeable up to Version 1.09. Make sure no other applications use this port) This
port is used for broadcasting the control signal to the inverters. If you change this
parameter, you need to change the parameter “network port for UDP packages” on the
inverters also.

Note
11.3 Minimum withdrawal from grid / Maximum feed in to
the grid
These parameters define how much power per phase should be either
-withdrawn from the grid in case of zero feed in
or
-fed into the grid in case of power reduction
11.3.1 Minimum withdrawal from grid (Zero Feed-in)
These parameters define how much power should be withdrawn from the grid. For
each inverter add 50 W with a total minimum of 100 W. This will prevent any feed in to
the grid, as there is always a small amount of consumption.
Positive values define the withdrawal. Maximum value is 320000 W
