Growatt MAX 125KTL3-X LV is a powerful 125kW three-phase grid-tied inverter designed specifically for commercial and industrial (C&I) solar applications. As part of Growatt’s advanced MAX series, this inverter delivers the highest output power for a string inverter with multiple MPPTs at the 400Vac level. Whether you’re looking to reduce electricity costs, maximize energy harvest, or achieve a lower levelized cost of energy (LCOE) for your PV plant, the MAX 125KTL3-X LV combines high efficiency, exceptional flexibility, and robust reliability in a single, compact platform.

Maximum Energy Yields
10 MPPT Trackers for Complex Installations
The MAX 125KTL3-X LV features 10 independent MPP trackers, each supporting 2 PV strings for a total of 20 DC inputs. This multiple MPPT design significantly reduces energy loss caused by shadow effects and module mismatch, allowing each string to operate at its maximum power point.
Compatible with High-Power Modules
With 32A MPPT current and 16A per string, this inverter is perfectly matched with today’s high-power and bi-facial solar modules. The wide MPPT voltage range of 180V to 1000V enables the system to start working earlier in the morning and switch off later in the afternoon, extending operation hours to harvest more solar energy.
150% DC/AC Ratio for Lower LCOE
Supporting up to 1.5 times DC oversizing, the MAX 125KTL3-X LV allows for greater PV array capacity, maximizing energy production and accelerating return on investment.

Comprehensive Safety & Reliability
IP66 Enclosure Rating
Built to withstand harsh environments, the inverter features an IP66 protection degree, providing complete protection against dust and powerful water jets for reliable outdoor installation.
Multi-Level Protection
Type II SPD on both DC and AC sides: Integrated surge protection devices safeguard the system against lightning and grid surges;
Integrated DC switch for safe maintenance and emergency shutdown;
Fuse-free design reducing maintenance requirements and fire risk;
Optional AFCI (Arc Fault Circuit Interrupter) protection to detect and mitigate fire risks from DC arcing;
Optional PID recovery function to prevent power degradation from potential-induced degradation;
String detection and IV curve scanning to accurately locate abnormal strings for proactive maintenance.
