The Huawei SUN2000-50KTL-M3 photovoltaic inverter is a three-phase 50 kW inverter with 4 MPPT and up to 8 monitorable strings, designed for large commercial and industrial photovoltaic systems. With efficiency up to 98.7%, IP66 protection and integrated protections, it is a reliable solution for large-scale production.
A string inverter for commercial use
The M3 series is Huawei's string range for large C&I systems. The 4 MPPT with up to 8 strings optimise production even with different roof pitches and orientations, reducing losses. String-level monitoring simplifies maintenance (O&M) on large systems.

Frequently asked questions
Is it a hybrid inverter?
No. The M3 series is a range of string (grid-tie) inverters for commercial photovoltaic production, not natively prepared for home storage.
Why are 4 MPPT an advantage?
The 4 MPPT independently manage several string groups, optimising production when panels have different orientations, tilts or shading — common on large roofs.
Can I monitor individual strings?
Yes. The inverter allows monitoring of up to 8 strings, useful for quickly identifying yield drops or faults on large systems.
Can I install it outdoors?
Yes. The IP66 rating allows outdoor installation with high resistance to dust and water jets.
