The GoodWe GW60KS-MT from the SMT series is a 60 kW three-phase grid-tied inverter, and its real selling point is not the 60 kW headline but the six independent MPPT trackers packed into one unit, which changes how an array can be laid out on a hotel or factory roof. It is one of the units our engineers specify when designing commercial systems for hotels, resorts and industrial buildings across Phuket, Phang Nga and Krabi. This page explains what each specification means for real annual yield. For the wider system picture, see our equipment overview.
What is the GW60KS-MT, and why do six MPPTs matter on a hotel roof?
The GW60KS-MT is a commercial string inverter rated at 60,000 W, able to push up to 66 kVA and 66 kW, designed for medium-sized rooftop arrays. Its defining feature is six independent MPPT trackers, each accepting two strings. An MPPT is the circuit that continuously tunes the array to its maximum power point, and it can only find one operating point per tracker. When panels facing different directions or receiving different amounts of shade are forced to share a tracker, the well-lit group gets dragged down to suit the compromised one. Phuket hotel and factory roofs are rarely one clean plane; they are broken into levels by height restrictions, plant rooms, water tanks and air-conditioning condensers that cast moving shade through the day. Six trackers let the array be divided to match that reality. On the DC side the unit accepts up to 1,100 V, operates between 200 and 950 V, takes 30 A per tracker and withstands 37.5 A of short-circuit current, which comfortably covers today's high-current modules. One honest caveat: the datasheet for this series does not state a numerical maximum PV input power, so any aggressive DC oversizing has to be confirmed with the manufacturer rather than assumed.
Highlights from the datasheet
- Six independent trackers, two strings each: the roof can be divided into six groups that operate separately, so panels shaded by a water tank in the afternoon do not pull down the output of a clear section. On a segmented roof this shows up as measurable extra kilowatt-hours, not just neater cabling.
- 30 A per MPPT with 37.5 A short-circuit rating: module currents keep climbing with each generation, and this headroom keeps panel selection open while still allowing two strings paralleled per tracker without hitting the current ceiling.
- 66 kVA apparent power on a 60 kW rating: that 6 kVA of headroom exists to meet power factor and reactive power requirements a utility may impose, so it is functional margin rather than a marketing figure.
- 98.1% European efficiency: the European figure is weighted across realistic part-load conditions all day. For a hotel running the system every day of the year, a difference at this level accumulates into visible kilowatt-hours on the annual bill.
- Thai grid settings printed in the datasheet: the document carries a footnote specifying 220 / 380 V output for PEA in Thailand, which means the factory has prepared settings for the local grid and reduces on-site configuration work.
- Rated to +60 °C and 0 – 100% humidity: a concrete roof deck in Phuket runs far hotter than ambient air in the afternoon. A wide operating window means more margin before the unit starts derating for temperature.
- Limitations worth stating: the datasheet gives no numerical maximum PV input power and no noise rating, and the unit uses smart fan cooling rather than the fan-free design of the residential models, so mounting position near guest rooms needs thought.

Why this model suits Phuket
- Hotel roofs are never one clean plane: local buildings are broken into levels by height limits and plot shape. Six MPPTs make it practical to use almost every usable square metre without sacrificing the good sections to the worst one.
- Humidity and salt air: the unit is rated to 100% humidity with IP65 protection, but because it uses fan cooling we select a mounting position out of direct sea breeze and schedule cleaning of the airways as part of maintenance.
- Hospitality load profile: the dominant loads are air conditioning and refrigeration, which peak at exactly the hours the array produces most. A 60 kW system is generally consumed inside the building rather than relying on export arrangements.
- PEA territory: Phuket is supplied by PEA, not MEA. We prepare the complete PEA permits package from electrical drawings through to inspection, and confirm the model's registration status with PEA before filing.
Who it suits
- Medium-sized hotels and resorts: buildings with multi-level roofs and heavy daytime cooling and hot-water loads
- Factories and warehouses: large metal-sheet roofs where fewer, larger inverters keep the switchboard compact and maintenance simple
- Restaurants and large commercial buildings: businesses where daytime electricity is a leading cost and the roof deck carries plant equipment that shades parts of the array
- Owners planning a phased rollout: starting with one unit and adding more later from the same family, keeping spares and servicing consistent
- Facility managers who need complete documentation: projects where manufacturer specifications must accompany permit applications and handover inspection
Summary
The GW60KS-MT suits commercial Phuket roofs that are anything but a single flat plane. Its practical strengths are six MPPTs at two strings and 30 A each, plus 98.1% European efficiency. The point to handle carefully is that its datasheet states no numerical maximum PV input power, so any oversized DC design must be confirmed with the manufacturer rather than estimated.
