You can ﬁnd this installation guide in our download area for the PIKO MP plus under Operating

manual.

The installation guide does not replace the operating instructions or manuals for the inverter,

battery and KOSTAL Smart Energy Meter required for correct assembly and installation.

IMPORTANT INFORMATION

Installation may only be carried out by a trained and qualiﬁed electrician!

Follow the safety instructions in the operating instructions for the inverter, battery and KOSTAL

Smart Energy Meter.

A battery activation code for the KOSTAL Smart Energy Meter and a computer / tablet are requi-

red to put the storage system into full operation and to make all the necessary settings.

For all work on the devices or on the supply lines, the power supply in the house, the inverter and

the battery must be completely de-energized. Take a look at the corresponding operating inst-

ructions for the respective devices (inverter / battery / KOSTAL Smart Energy Meter).

PIKO MP plus applications

The PIKO MP plus can be used as a PV inverter, battery inverter or as a hybrid inverter with and without

a battery.

input to battery, press the SET button in the main menu of the inverter under Settings > Service >

Inputs > DCx until Battery is shown in the display for the DC input. Exit the menu with the ESC key.

The DC input is now switched to battery.

DCx = DC1 for PIKO MP plus xx-1 (AC-storage mode with 1 MPP tracker)

DC2 for PIKO MP plus xx-2 (AC- or hybrid storage mode with 2 MPP trackers)

INFO

To access the service menu, press the arrow keys and on the keyboard simultaneously for

a few seconds in the Service menu.

P After this conﬁguration, the display of the inverter lights up in red and shows the following error

message because the inverter and the battery in the KOSTAL Smart Energy Meter have not yet been

conﬁgured.

14. Finally, the transfer of the data to the KOSTAL Solar Portal must be set up.

Set up data transfer to the KOSTAL Solar Portal

The yield data of the overall system can be called up via the KOSTAL Solar Portal or the KOSTAL Solar

App. To do this, the inverter and the KOSTAL Smart Energy Meter must be conﬁgured to send data to

the KOSTAL Solar Portal.

1. The transfer of data (yield data) is activated in the PIKO MP plus as follows:

2. The transfer of data (house consumption, self-consumption and battery values) is activated in the

KOSTAL Smart Energy Meter via the menu item „Inverter „Solar Portal“.

Set up the PIKO MP plus inverter and the KOSTAL Smart Energy Meter in the KOSTAL Solar Portal

via the menu item „System list“ > „Inverter“
