Energy meter connection

Limitation of active power to [W]

Set the max. feed-in capacity. Requirements relating to this are generally specified by the energy supply company (e.g. a limitation to 70 %). The inverter's max. power serves as the default. Use the calculator to easily calculate the reduction.

Storage of excess AC energy from local generation

If there is an additional AC energy source in the local house grid (e.g. an additional PV system or a combined heat and power unit), the AC energy generated by this source can be stored in a battery connected to the PLENTICORE plus.

NOTE! The function can only be activated if the energy meter has been installed at the grid connection point (position 2) and there is a battery connected to the inverter. If storing surplus AC energy from local generation (Smart AC Link function) has been activated, the "Smart Battery Control" function is not available.

Activated: The AC energy generated can be stored in the battery.

Deactivated (default): Extra generated AC energy is not stored in the battery.

Activate receipt of broadcast control signals

If there is a ripple control receiver connected to another inverter's digital inputs, the signals for active and reactive power control can be allocated to all inverters in the local area network (LAN) by means of UDP broadcast. A local energy manager can also generate signals for active and reactive power control in the local area network.

Activated: The inverter is controlled by means of a ripple control receiver connected to another inverter.

Deactivated (default): The signals are not evaluated. The inverter is not controlled by means of a ripple control receiver connected to another inverter.

 

MPP tracking optimisation settings.

Parameter

Explanation

Generator settings

None: No optimisation is perform.

Shadow management: If PV strings are in partial shading, the PV string affected no longer achieves its optimum performance. If shadow management is activated, the inverter adapts the MPP tracker of the selected PV string such that it can operate at maximum possible performance.

 

If a battery is connected to the inverter, its behaviour and usage of the battery can be configured here.

IMPORTANT INFORMATION

notice

If a battery is set up at a later date via the Webserver or inverter, use the DC switch to switch the inverter off and on again after configuration so that the settings are adopted.

Parameter

Explanation

Battery type

Select the battery connected to the inverter.

Battery control

The battery can be controlled by an external battery management system (e.g. energy supplier). In this case, the charge/discharge capacity of the battery is controlled by the external supplier. The plant owner then receives remuneration for the energy provided, e.g. from the external supplier.External battery control

Internal (standard):

The external control is deactivated.

Via digital I/O:

External battery management is carried out via the digital inputs on the Smart Communication Board (terminal X401) of the inverter. A presetting can be selected or the digital inputs can be configured according to the provider's specifications.
If there are no control signals, the system switches to internal control. It is still possible to read out the device status in parallel using Modbus (TCP)/SunSpec. External battery control

Via Modbus (TCP):

The external battery management is provided via the Modbus RTU protocol. The control signals are received via the LAN interface. If there are no control signals, the system switches to internal control. It is still possible to read out the device status in parallel using Modbus (TCP)/SunSpec.

Battery discharge as of grid demand of [W]

Input of a minimum grid demand value as of which the battery is used. (Standard 50 W.)

Example: If a value of 200 W is set, the battery can only be released to cover the home consumption when the measured grid demand from the public grid exceeds 200 W. The battery is blocked again for home consumption when the grid demand falls 50 W below the set value (in this example 150 W).

Min. state of charge (SoC) [%]

Set the minimum depth of discharge of the battery.

If the smart battery control is also activated, the depth of discharge is automatically adjusted depending on the weather conditions and forecast to make optimum use of the battery.

Smart battery control

Charging and discharging of the battery are controlled completely automatically here. This function should only be activated if the connected PV power is greater than the PV power of the inverter (limitation of inverter set e.g. to 70 %). You should not use this function if an electric vehicle is charged via a wallbox, as no clear consumption forecast can be determined here.

If Storage of excess AC energy from local generation (Smart AC Link function) has been activated, the "Smart Battery Control" function is not available.

You will find a detailed description in Smart battery control.

Time-controlled battery usage

The charging and discharging operation can be configured very flexibly at different times (tariff periods).

There are times when the costs of electricity procurement are relatively high (different tariff models). Therefore, it may make sense to allow the battery to discharge during these periods and to allow charging outside of these periods.

The times set here can be overridden by the specifications of an activated external battery management system.

Battery charge blocked: battery discharge permitted in the event of demand from house.

Battery discharge blocked: battery charge permitted in the event of excess power.

Advanced battery options – Service charging (only possible with service code)

Start service charge to 100%

If the SoC of the battery is very low during initial commissioning, this function can be used to charge the battery to 100% once. This is done with solar power or, if there is not enough solar energy available, with energy from the public grid. In this case, "Service charging" is displayed on the inverter.

Explanation

Residual current protection equipment

Compatibility of type A RCD:

If this function has been activated, type A RCDs can be used as residual current protection equipment. In such cases, the inverter shuts down when the residual current becomes incompatible with a type A RCD.

If the function is deactivated, a type B RCD must be used as residual current protection equipment if an RCD is stipulated.

 

Parameter

Function

none

There is nothing connected to the digital inputs.

External battery control

If you have activated external control via the digital I/O ports in the "Battery settings" menu, you can define the functions of the inputs here. Assign the desired charge or discharge power to the inputs.

Active power control

For the connection of a ripple control receiver with standard switching specifications.

Detailed description in chapter Self-consumption. Active power control

Activate the distribution of ripple control signals in the house grid.

Activated:
If a ripple control receiver is connected to the inverter, the control signals of this ripple control receiver are distributed in the local LAN network by means of UDP. Other inverters can therefore also be controlled using the connected ripple control receiver.

Deactivated:
The control signals are not distributed in the local LAN network by means of UDP.

User-defined active/reactive power control

For the connection of a ripple control receiver. Unlike the standard active power control, here you can specify up to 16 settings. These are usually specified by the energy supply company.

Detailed description in chapter Self-consumption. Active power control

Activate the distribution of ripple control signals in the house grid.

Activated:
If a ripple control receiver is connected to the inverter, the control signals of this ripple control receiver are distributed in the local LAN network by means of UDP. Other inverters can therefore also be controlled using the connected ripple control receiver.

Deactivated:
The control signals are not distributed in the local LAN network by means of UDP.

 

The inverter is equipped with four switched outputs. The switched outputs can switch external consumers for the purpose of increasing self-consumption or can be configured as indicators for statuses or events. A detailed description can be found in and a description of installation in Connection of switched outputs.

Set the function of the switched outputs (terminal X1401 and X1402) on the Smart Communication Board. The 2-pin terminal can be assigned various functions.

Parameter

Explanation

Output

Shows outputs 1-2 on terminal X1401 and outputs 3-4 on terminal X1402.

Operating mode

Select mode:

Off: The switched output is deactivated.

Load control: Switches on loads when conditions are set (e.g. PV excess).

SG ready: Using the SG Ready function is a simple and cost-effective solution to increase PV self-consumption by using a heat pump. The inverter makes it possible to control a heat pump compatible with SG Ready. The SG Ready specification's operating statuses 2 (normal operation) and 3 (start-up recommendation) are supported.

Wallbox: For controlling a wallbox so that it starts the charging process for an electric vehicle connected to the wallbox under certain conditions. The wallbox must have a control input. For more information, please refer to your wallbox's manual.

Events: The output is switched when a certain event occurs. The event must be selected from the list.

External control: The output can be switched by an external energy management system via the Modbus/TCP protocol.

State

Select the function of the switched output. Function as potential-free normally open contact (NO) or normally closed contact (NC).

The contact is closed or opened when the set conditions are met.

Battery use for switching based on PV power

The settings made here apply to all outputs where switching is configured based on PV power.

 

Activate the evaluation of an external message signal. The inverter can evaluate the message output of the overvoltage modules (SPD) and output a message if an event occurs. Information on connection and wiring can be found under Connecting the signal contact for the external overvoltage protection (SPD – Surge Protective Device).

NOTE

Info

The setting can only be carried out by an installer with a service code.

Evaluation of the external message signal
