MAX 100-150KTL3-X LV/MV
MAX 100-150KTL3-X LV/MV has same modbus protocol type with MAX 50-80KTL3 LV/MV
MAX 100-125KTL3-X LV
Datasheet
Feature
▲ BOOST has a total of 10 MPPTs, each with only a single IGBT (freewheeling diode SiC), and different MPPTs work with each other
operate in interleaved mode; There are 10 channels in boost, and each channel does not play waves at the same time, but the other is that 10 channels are interleaved on average within 360°
▲ Two string inputs for each MPPT, with string detection function as standard;
▲ DC-LINK capacitor adopts electrolytic + film combination scheme, increasing capacity has a very obvious effect on output characteristics/stability
role, and then to be solved is to reduce the electrolytic ripple current to ensure life;
▲ The inverter adopts three-level I-shaped TOP;
▲ AC output adopts LCL topology;
▲ Nighttime SVG functionality, added as a new feature
▲ PID SPS and AC SPS integration;
▲ The control board follows the main DSP+secondary DSP+CPLD scheme of the MAX 80K series;
▲ The monitoring display adopts STM3 ARM chip, LCD display is optional, USB/RS485 communication
▲ In terms of other functions, it meets the second-level lightning protection and is reserved for optional AFCI;
▲ Support remote programming
