LOHER DYNAVERT R
A photovoltaic inverter for intelligent grids
With LOHER DYNAVERT R, Siemens offers a ready to run grid inverter with high reliability, high efficiency and high power quality to supply energy from photovoltaic sources grid compliant to the AC grid.
The energy transmission and distribution requires more intelligence to operate with volatile energy generation, which is the case with renewable energy sources, and keep the grid stable for example in terms of voltage drop and other unwanted reasons. Inverters are here needed, to decouple the variable energy source generation from the grid and to control a constant and stable energy supply to the grid. We provide high dynamic control functions for a stable and intelligent operation.
Technical data overview
Up to 826 kVA
Maximum DC start voltage
Up to 930 VDC (1050 VDC with option)
Cooling air temperature range
From -10 °C up to +45 °C without derating
Efficiency up to 98.8 %
Auto increased AC power
Active and reactive power control
Lightning protection (LPZ2)
Supporting Low Voltage Ride-Through (LVRT)*
Maximum Power Point Tracking (MPP Tracking)**
Optimized for Inverter Management Software (IMS)
* With LVRT support power generating solar plants can continue to operate through short periods of low grid voltage and not disconnect from the grid.
** MPPT takes care that the load characteristic that gives the highest power is optimized and gives you the maximum point of efficiency due to the amount of sunlight falling on the solar panels.
LOHER DYNAVERT R offers lasting customer benefits:
Top quality and maximum availability based on decades of experience in electrical engineering for inverters and the application of robust SIEMENS industrial standard inverters proven millions of times worldwide.
Best in class efficiency and compactness:with an efficiency of maximal 98.8 % a benchmark in all global markets. Furthermore its compact and robust design makes integration into containers with limited space very easy.
functionalities for grid operation, communication options and control functions it is a rounded solution for renewable energy supply to the grid.
Based on state-of-the-art
dual processor technology, the CB08 control board controls the complete converter sequence. The CB08 masters all situations, starting from the grid monitoring, through synchronization to the grid, up to a defined shutdown when faults occur.
The inverter includes also
lightning protection at AC and DC side, lightning protection zone 2 (LPZ2).
The inverter offers easy
connectability due to a separate DC and AC cabinet integration.
