Growatt MAC50 70KTL3 X2
Commercial solar installations demand robust inverters that can handle substantial power loads while maintaining peak efficiency. Engineered by Growatt, this Mac50 70Ktl3 X2 model represents advanced three-phase inverter technology designed for large-scale photovoltaic systems. With its impressive 98.8% maximum efficiency rating, this unit minimizes energy losses during DC to AC conversion, ensuring optimal power output for commercial and utility-scale applications. The inverter features dual MPPT channels, each capable of handling up to 64 amperes of DC input current, providing excellent flexibility for complex solar array configurations. Its IP66 protection rating guarantees reliable operation in challenging outdoor environments, protecting internal components from dust ingress and powerful water jets. This makes it particularly suitable for rooftop installations and ground-mount solar farms where weather resistance is crucial for long-term performance and minimal maintenance requirements.

Frequently asked questions
What is the Growatt MAC 50-70KTL3-X2 used for?
The MAC series sits in Growatt's mid-scale commercial line, above the residential MIN and MOD inverters, and the MAC 50-70KTL3-X2 is built for commercial roofs or small ground-mount sites rather than a single home. Its recorded maximum efficiency of 98.8 percent is high for this class, meaning conversion losses stay small even at part load through most of the day.
What does the 50-70KTL3 span in the MAC 50-70KTL3-X2 name mean?
The "50-70" in MAC 50-70KTL3-X2 names a family spanning roughly 50 to 70 kW of AC power rather than one fixed rating, and Growatt does not publish which figure in that range this specific catalog entry represents. What is verified for this listing is a maximum DC input current of 64 A per MPPT channel and 98.8 percent maximum efficiency, both specific to this entry.
How much DC current can each MPPT input on the Growatt MAC 50-70KTL3-X2 handle?
The Growatt MAC 50-70KTL3-X2 accepts up to 64 A of DC input current per MPPT channel, a notably high figure among the commercial Growatt units on this site. That headroom lets an installer put large parallel strings, or several strings combined before the inverter, on a single channel, which reduces the number of separate MPPT inputs a large array actually needs.
Can the Growatt MAC 50-70KTL3-X2 be installed outdoors?
The Growatt MAC 50-70KTL3-X2 carries an IP66 enclosure rating, meaning it is sealed against dust and protected against powerful water jets from any angle, which keeps outdoor mounting within its specification. Temperature range and weight are not recorded for this listing, so installers planning a rooftop or ground-mount site should check those figures on the manufacturer's datasheet.
