MAX 230K, 253K 15 MPPT Product Appearance

1) There are a total of 15 MPPT channels on the BOOST side. Each 3 MPPT share a BOOST-IGBT module. Each channel has two freewheeling diodes. tubes (all integrated inside the module); each module has a matching flying capacitor plate

2) No fuse design on the PV side, two MPPT string inputs per channel, and standard string detection function

3) The bus capacitor adopts an electrolytic + film combination scheme. The electrolytic capacitors are distributed on two electrolytic capacitor plates, and the film capacitors are divided into Distributed on POWER board;

4) The inverter side adopts an I-shaped three-level topology, and each phase output uses an inverter-IGBT module.

5) The filtering at the AC output adopts LCL topology, which can better reduce THD and meet grid connection requirements.

6) Support reactive power scheduling to meet static SVG requirements

7) Equipped with secondary lightning protection function to ensure safe operation of the inverter

8) With leakage current protection function to ensure the safety of installation, operation and maintenance personnel

9) With AFCI function (optional);

9) This model does not have PID function internally and requires external configuration (optional)
