Huge demand for capacity with a storage solution
KOSTAL’s inverter partnership
KOSTAL has the perfect solution for these higher power solar systems: namely a partnership involving an inverter from the PLENTICORE plus series and an appropriate storage solution from a well-known manufacturer, such as BYD, BMZ or Nilar.
If customers opt for two PLENTICORE plus inverters in their device network, they can easily install systems of between 3 and 30 kWp. The entire PV power is then available for surplus charging of the connected battery storage unit. This makes dynamic 70-percent limitation (as required by the Renewable Energies Act) possible as well as external limitation via a ripple control receiver. Five MPPT inputs provide maximum flexibility in terms of the module design, enabling any roof orientation to be covered.
The self-learning shadow management feature of the PLENTICORE plus inverter ensures maximum yields from solar power generation. It is incredibly simple to interconnect the two inverters with the battery unit.
How to produce systems conforming to the Renewable Energies Act
The battery is connected to the more powerful of the two PLENTICORE plus when in “hybrid inverter” mode. The second inverter is easily integrated into the system as a pure solar inverter. When the “storage of surplus AC energy” function is activated, the PLENTICORE plus supplying the battery can also receive this energy on the AC side and transfer it to the connected storage unit.
The energy generated via the two inverters is then available to charge the battery. At the same time, two inverters provide a total of five PV inputs for high-performance solar operation. This guarantees sufficient power even when the sun is not shining.
Depending on the device combination, the AC power can be easily and purposefully aligned with the PV system in say 1.5 kW steps. Therefore, battery capacities of between 5 and 22 kWh can be achieved with ease.
PLENTICORE plus: great performance, great flexibility
As a three-phase hybrid device, the PLENTICORE plus is suited to both new installations and retrofits. This hybrid inverter from KOSTAL reliably delivers between 3 and 10 kW – perfect for extending a PV system with an appropriate storage unit, e.g. from BYD, BMZ or Nilar.
