On-Grid Three-phase Inverter Growatt 10kTL3-X Hybrid, 10kW

The panels produce direct current, and this device turns it into the current in the socket and distributes it on the three phases of the house. It has two independent trackers, which means you can mount panels on two roof slopes, oriented differently, without the weaker group dragging down the production of the other. It cools itself, without fans, so it works quietly and has fewer moving parts.

With 10 kW of rated power, it suits an installation of approximately 8-12 kWp, the typical size for a house with a three-phase connection or a small office. The maximum efficiency is 98,6% (98,1% European efficiency), and at night it consumes only 1 W. It weighs 14 kg and measures 425 x 387 x 178 mm, so it can be wall-mounted by a single installer, and the IP66 protection allows placement outdoors too, at temperatures between -25 and +60 degrees C. Production is tracked in the ShinePhone app, and an LED display shows the status locally as well. Note the commercial name: the code 10KTL3-X is the pure on-grid version of the MOD family; the hybrid version, with a battery, is 10KTL3-XH, and the specifications here are those of the on-grid version.

DC: maximum voltage 1.100 V, start-up from 160 V, MPPT range 140-1.000 V, 2 MPPT with 2 inputs (MC4 connectors), maximum DC current 26 A. AC: maximum current 16,7 A, frequency range 45-65 Hz, THD below 3%; transformerless topology. Maximum efficiency 98,6%, European efficiency 98,1%, night consumption 1 W. IP66 enclosure with natural cooling, 425 x 387 x 178 mm, 14 kg, -25...+60 degrees C, maximum altitude 4.000 m; communication RS485, USB and WLAN, with local LED display and ShinePhone monitoring.

Who it suits

Suitable for a house with a three-phase connection and a system of 8-12 kWp, especially when the panels are split over two different roof orientations.

Terms explained

• On-grid: System connected to the grid, which uses solar energy in real time and sends the surplus into the grid; it does not work during a power outage.
• European efficiency: A weighted average that shows how efficiently the inverter works over a real year, not only at maximum power.
• MC4 connector: The standard plug used on photovoltaic panel cables, with a lock, so that it does not come apart accidentally.

Technical specifications

Recommended applications

• Residential three-phase photovoltaic systems of 8-12 kWp
• Household prosumers connected on a three-phase connection
• Small commercial consumers: offices, practices, workshops
• Installations with a roof on two different orientations (2 MPPT)

Technical details

Series-level specifications — valid for the product family

Growatt MOD 10KTL3-X is a three-phase photovoltaic inverter connected to the grid, with a rated AC power of 10 kW and output on 3 phases. The DC side accepts a maximum voltage of 1100 V, starts from 160 V and works over a wide MPPT range of 140-1000 V, through two independent MPPT trackers with two DC inputs (MC4 connectors) and a maximum DC current of 26 A. This configuration allows the strings to be oriented on two different slopes or azimuths without significant production losses.

On the grid side, the inverter delivers a maximum AC current of 16,7 A, works in the frequency range 45-65 Hz and keeps a THD below 3%. The maximum efficiency is 98,6%, and the European efficiency 98,1%, values typical for the transformerless topology used by the MOD X series. Night-time consumption is only 1 W.

Constructively, the enclosure has IP66 protection with natural cooling (without fans), dimensions of 425 x 387 x 178 mm and a mass of 14 kg, which allows mounting by a single installer. The operating temperature is -25...+60 degrees C, the maximum altitude 4000 m, and communication is done through RS485, USB and WLAN, with a local LED display and monitoring through the ShinePhone app.

Note the commercial name: the code 10KTL3-X corresponds to the pure on-grid version of the MOD family; the hybrid version with battery coupling is coded 10KTL3-XH. The specifications above are those of the on-grid version MOD 10KTL3-X.
