PIKO MP plus

PIKO MP plus as a hybrid inverter: Generate and use solar power efficiently, even in smaller PV systems

The single-phase KOSTAL PIKO MP plus as a hybrid inverter enables solar power to be generated and the solar energy obtained to be stored.

KOSTAL PIKO MP plus: the hybrid inverter for small photovoltaic systems

The PIKO MP delivers extremely stable yields and its broad input voltage range provides numerous wiring options for the PV modules.

In combination with the KOSTAL Smart Energy Meter, the PIKO MP plus changes from a pure solar inverter to a hybrid inverter and, in addition to the PV generator, also offers a connection option for charging and discharging a storage unit. The PIKO MP plus hybrid inverter is ideally suited for small photovoltaic systems on single-family homes.

PIKO MP plus: independently tested

PIKO MP plus being tested

The PIKO MP plus clearly outperformed the established market leaders in HTW Berlin's 2021 Energy Storage Inspection.

The single-phase PIKO MP plus 4.6-2 showed its strengths in both DC and AC operation, achieving high efficiencies with an SPI of 90 percent (DC) and 89.6 percent (AC).

This is thanks to its high battery efficiency coupled with fast settling time and low standby consumption with high inverter efficiency.

The single-phase inverter of the PIKO MP plus series is therefore particularly economical as a conversion and control unit for solar systems with connected storage.

Benefits for you

Battery option possible at any time with KOSTAL Smart Energy Meter

Battery functionality for devices with two MPP trackers for DC-coupled battery connection: ideal for new installations or AC coupling for simple battery retrofitting

Extended MPP range – perfect for repowering

Perfect for small photovoltaic systems

In the power ratings from 3.0 to 5.0 kW, the PIKO MP plus offers variants with 2 MPP trackers, one of which can be used as a bidirectional port for PV, as well as for a high-voltage battery. This means that the PIKO MP plus can be used as a hybrid inverter in combination with the KOSTAL Smart Energy Meter. In this case, the KOSTAL Smart Energy Meter takes over responsibility for the energy management and controls the energy flow of the inverter.

The PIKO MP plus is particularly well suited as a hybrid inverter when installing a new photovoltaic system on a small roof area or in a country where most house connections are single-phase.

Generate and store solar power with the PIKO MP plus hybrid inverter

Can be used as a solar inverter and can be retrofitted with a battery at any time using an activation code.

Small system & shading – what to do?

Like all solar and hybrid inverters from KOSTAL, the PIKO MP plus also includes integrated shadow management. Thanks to this, high yields can be achieved even when there's shade as a result of chimneys or trees, for example.

The shadow management system adapts quickly and individually to the location's conditions.

Product advantages

Integrated shadow management that adapts individually to the installation location

Standard integrated communication package with data logger, system monitoring and Webserver

Connection of KOSTAL Smart Energy Meter for battery control

Single-phase grid feed-in: perfect for smaller PV systems

Zero feed-in possible

Free PV system monitoring via the KOSTAL Solar Portal and KOSTAL Solar App Product advantages

Install the hybrid inverter now and simply retrofit the battery later

The PIKO MP plus gives the operator the option of installing it as a solar inverter without a battery to start with. The second MPP port can be used for the battery at a later time. And the owner only pays for this option when it's really needed. Simply purchase an activation code and the KOSTAL Smart Energy Meter via the KOSTAL Solar webshop and the retrofitting can begin. This function only applies to performance ratings 3.0-2, 3.6-2, 4.6-2 and 5.0-2, as the PIKO MP plus is equipped with 2 MPP ports.


With the PIKO MP plus, you can also decide on a battery at a later date. You only pay for the battery upgrade when you really need it.

Also perfect as a replacement device for old inverters 

Currently, when connecting the battery, the high-voltage battery from BYD can be used. As a hybrid inverter, the PIKO MP plus offers the perfect replacement option for old, single-phase PV inverters. At the same time, the single-phase device has a compact design, so it requires less space than many older generation inverters. Thanks to the battery option, system owners are also perfectly equipped for new technologies in the future.
