Operating Principle and Use of the System
2. Operating Principle and Use of the System
2.1 Purpose and functionality
The high-quality inverter (HKW10NVP3) converts direct current generated
from the solar modules (DC) into grid-compliant alternating current (AC),
which can be used for self-consumption or fed into the public grid,
or the generated energy can be stored for later consumption in the 2-8
integrated 5.12 kWh battery modules (KKTNVB5.1).
The respective operating status depends on the availability of PV energy
and the corresponding setting.
Furthermore, for power outages, emergency power can be provided
by using the energy (generated by the PV) from the inverter
and from the battery storage.
2.2 Connection types
The energy storage system can be applied
• DC- coupled (mostly new installation),
• AC-coupled (mostly retrofit)
• and Hybrid-coupled (mostly retrofit, and PV capacity-increase),
as the following schemes show:
Note:
The connection diagrams are for reference only.
For connection, also observe the instructions in the corresponding
sections of this manual!
The entire electrical connection must comply with the requirements
of the local regulations.
