The Growatt MID 50KTL3-X2 is a 50kW three-phase on-grid solar inverter with four MPPT trackers and an 8-year warranty, from Growatt's MID commercial range, built for commercial and industrial rooftops with complex or multi-orientation layouts.
An on grid solar system is the simplest configuration in solar and the shortest payback. No batteries, nothing to replace in five years, nothing to maintain. This growatt solar inverter ties directly to your DISCOM connection, powers your load through the day, and exports the surplus through net metering so your meter runs backward the credit offsets your night and weekend consumption. For a factory, a warehouse, a commercial complex, or an institution with strong daytime load, a grid-tied system at 50kW turns a large roof into the shortest-payback asset on the balance sheet.
Four MPPT trackers, and why that is the reason to choose this over the MAC 50. Both are 50kW three-phase units. This MID version runs four independent MPPT trackers; the MAC 50KTL3-X LV runs three. The extra tracker matters on a roof that is broken up multiple orientations, several shading sources, or an irregular layout across the day. Four trackers let more sections of the array generate at their own maximum instead of being averaged down to the weakest string. On a clean, uniform 50kW roof, the MAC's three trackers are sufficient and the more economical choice. On a complex roof, the MID's fourth tracker recovers generation the MAC would lose. Send our team your roof layout and we will tell you which of the two your site actually justifies the higher tracker count is not always worth the premium.
The 8-year warranty on the single point of failure. In a commercial installation the inverter fails before the panels, and its downtime stops the array, not one string. Eight years of manufacturer cover, backed by Growatt's established Indian service network, is what protects the project economics through payback. On a commercial roof, warranty length and service response time are not features they are the risk model the project is underwritten on.
Sizing it correctly. A 50kW inverter suits roughly a 50–65kW panel array depending on your DC-to-AC ratio and roof orientation. Undersize it and you clip generation on peak days. Oversize it and you have paid for headroom you never use. Send our team your panel count, wattage and roof layout and we will confirm 50kW is right, or point you to the 40kW or 60kW.
SolarClue is India's managed solar marketplace. Our team confirms this inverter matches your panel array, your three-phase supply and your DISCOM's net metering requirements before you order. Compare it against the MAC 50 and against Deye's 50kW on our platform we will tell you which suits your roof, not which we are holding. You book with a token payment rather than the full amount upfront. Supply and installation are coordinated through verified partners, and we handle Growatt warranty support afterwards.
