Off-Grid Solar Inverter 10kVA - 120kVA (3:3)
Off-Grid Solar Inverter 10kVA - 120kVA (3:3)
This Off-Grid solar system is available in 10 kVA ~ 120 kVA models with DSP digital control technology, it is combined with pulse-width modulation (SVPWM), disturbance MPPT control and multi-level control technology to enable the system to track the maximum power of solar panels fast. Its secure power supply feature provides good quality powerwith regulated voltage and frequency to the loads, and it is featured with energy storage and staggering power consumption as well. It is an ideal inverter for medium-sized or large-scale residential, commercial and industrial PV applications which are off the grid, such as village, farm, factory, office building and islands etc.
