Based on HF chain and parallel operation technology with DSP, several inverter can be parallel operated and run, simplified the design of the power station. Adopted the IPM module of 5th generation of Mitsubishi, increasing the system efficiency greatly. Self-optimizing of MPPT, increasing the efficiency of power produce of PV Adopted the technology of initiative frequency offset to detect the island, make the grid protecting safe and reliable Large screen of multiple language of LCD display. Power production and CO2 emission reduction calculation for 5 Flexible output setup, suitable to various countries' local regulationSpecialized remote setting and detecting software, make the computer adjusting more intelligently Delicate machinery design and light component configuration Multi-protection design, make it more safe and reliable Electrophoresis painting and machinery design of high protection grade, suitable for install indoor and outdoor Wider range of operating temperature of -25~+50¡ãC Plug-in connection for all DC and AC water proof connector and communication cable, easy to field wiring
