LIVOLTEK grid inverter 20 kW
The LIVOLTEK HP3-20KT2 inverter is a three-phase grid-tied inverter with a power of 20 kW, intended for connection to the electrical grid in residential and commercial solar power plants. Thanks to two MPPT trackers and built-in Wi‑Fi, it provides high efficiency and convenient system performance monitoring.
Main features:
-
Two MPPT trackers: optimal energy management from different groups of solar panels.
-
Built-in Wi‑Fi: monitoring and control via a mobile app or web interface.
-
High efficiency: up to 98.1% efficiency, minimal energy losses.
-
IP65 protection: suitable for outdoor installation in harsh weather conditions.
-
Wide MPPT voltage range: 150–950 V, compatibility with various solar modules.
-
Grid-tied operation mode: direct connection to the grid without support for off-grid battery use.
-
Scalability: ability to expand the system as energy needs grow.
