Inverters for Residential Systems
PLENTICORE G3 – Latest-Generation Universal Inverter
The PLENTICORE G3 is Kostal’s premium model.
- Hybrid-ready out of the box, with an integrated battery charging port that can be flexibly expanded
- 2 plus 1 MPP trackers, offering high flexibility in system design
- Optional battery connection that can be enabled
- Integrated EEBUS communication for smart consumption control
- Compatible with select high-voltage storage systems such as the KOSTAL HELIVOR HV and BYD Battery-Box Premium; Type 2 DC surge protection can be retrofitted as an option; IP65
- MDC-capable with the appropriate software version
The PLENTICORE G3 is ideal for residential systems, energy storage solutions, and sector coupling. It is manufactured in Germany and offers high safety, flexible expandability, and convenient commissioning.
PLENTICORE MP G3 - Single-Phase and Flexible
The PLENTICORE MP G3 adds a single-phase solution to the Kostal system portfolio.
- For smaller PV systems, repowering, and energy storage applications
- 1 plus 1 or 2 plus 1 MPP trackers, depending on the device variant
- Optional battery connection and flexible power expansion
- MDC-capable with the appropriate software version
This makes the PLENTICORE MP G3 the ideal solution for projects that require a compact design, simple planning, and high system flexibility.
PLENTICORE plus G2 - The proven all-rounder
- Also hybrid-compatible
- 2 MPP trackers plus an activatable battery connection or third DC connection
- With integrated energy management[KR1.1]
The G2 is the robust solution for small to medium-sized PV systems.
HELIVOR HV - The Battery Storage Solution That Always Fits
- Safe prismatic LFP cell technology
- Easy installation (Plug & Play) with PLENTICORE’s automatic battery detection
- Wide range of capacities (6.4 – 28.8 kWh)
- Parallel operation of up to 8 battery towers
- IP65 protection rating
Multi Device Control – More Power in a Network of Devices
Multi Device Control – More Power in a Network of Devices With Multi Device Control (MDC), Kostal is expanding the PLENTICORE G3 and PLENTICORE MP G3 inverters to include central control for systems with multiple battery storage units. One inverter acts as the host, controlling up to two additional compatible devices. This creates a high-performance system comprising up to three hybrid inverters with up to 60 kW of combined charging and discharging power.
Key Benefits for Installers
- Centralized configuration and visualization in the host inverter
- LAN networking of devices
- Flexible combination of compatible battery storage systems from different manufacturers and with varying capacities
- Suitable for projects with high self-consumption, dynamic grid connection control, and controllable loads
- Existing devices can be integrated into the MDC network via a software update
For operation within the MDC network, a Kostal Energy Meter (KEM) or a Kostal Smart Energy Meter (KSEM) is required at the grid connection point. Both devices monitor the system’s energy flows and provide the host inverter with important data on consumption and feed-in
Wallbox and Smart Charging with Kostal
ENECTOR - The Smart Wallbox from Kostal
- PV surplus charging possible via the Kostal Smart Energy Meter
- AC charging power up to 11 kW
- Ready to connect, easy installation
- Optional activation code for additional convenience features
- IP54 protection rating, suitable for indoor and outdoor use
The ENECTOR Wallbox complements the Kostal system ecosystem with a simple and efficient charging solution for electric vehicles. When combined with an inverter, storage system, and energy meter, self-generated solar power can be specifically used for e-mobility.
