Growatt MOD 10KTL3-HU – 10 kW 3-phase hybrid inverter with backup

The Growatt MOD 10 KTL3-HU is a powerful 10 kW 3-phase hybrid inverter for those who want to generate a lot of solar power now and easily connect a high-voltage battery later. With three MPP trackers, integrated backup function and support for Growatt APX batteries, you can build an installation ready for dynamic energy contracts and emergency power supply.

This inverter combines high efficiency with comprehensive protection: AFCI arc flash detection, Type II overvoltage protection on both AC and DC sides and integrated DC switch. Natural cooling ensures quiet operation and, thanks to IP66, you can mount it indoors or outdoors.

Key benefits of the Growatt MOD 10KTL3-HU

• 10 kW 3-phase hybrid inverter – suitable for 3×400 V + N connections in homes, farms and small businesses.
• Battery ready – directly compatible with Growatt APX high-voltage batteries; no additional battery inverter required.
• Integrated backup function – emergency power capability without separate backup box (with additional cabling/group).
• Three MPP trackers – ideal for multiple roof surfaces or combinations of pitched/flat roof.
• High efficiency – maximum efficiency up to approx. 98.6% and high European efficiency for minimum conversion losses.
• AFCI arc detection – increases safety in DC wiring on long runs and large roofs.
• Type II SPD on AC as well as DC – integrated surge protection against lightning and switching surges.
• Quiet operation – transformerless and natural convection cooling, so no noisy fans.
• IP66 protection rating – dust- and waterproof, suitable for mounting in the technical room, garage or outside on the facade.

Application: when to choose the MOD 10KTL3-HU?

The Growatt MOD 10KTL3-HU is a logical choice if you:

• Have a 3-phase house connection (3×400 V + N).
• Want to connect between roughly 10 and 20 kWp of solar panels (overdimensioning up to about 200% is allowed according to datasheet).
• Have multiple roof areas (e.g. east/south/west) and want to optimise the strings separately via 3 MPP trackers.
• Want to add a Growatt APX high-voltage battery in the future without additional hardware.
• Want to have backup power for critical groups (refrigerator, lighting, router, e.g. via a separate backup group).

Installation tips for do-it-yourselfers and installers

• 1. Check your grid connection
  This inverter is designed for a 3×400V + N connection. Check in your meter box whether this corresponds to the main connection and the grid operator’s requirements.
• 2. String design over 3 MPP trackers
  Divide your roof areas logically over the three MPP trackers (e.g. east, south and west). Make sure each string falls within the MPPT range of 140-1,000 V, even at low winter temperatures.
• 3. Reserve space for battery and backup
  If you want to add a Growatt APX battery and back-up groups later, plan the location of battery, DC cabling and back-up distributors now.
• 4. Choose mounting location
  Hang the inverter on a solid wall, out of direct sunlight and with enough free space around it (top/bottom/side) for cooling and maintenance.
• 5. Set up monitoring immediately
  Connect the communication (e.g. via WiFi or LAN dongle) and register the installation in the Growatt monitoring portal. This allows you to see yield, consumption and battery status from day 1.
• 6. Mains connection by a certified installer
  In most cases, you can prepare and install the system yourself, but it is best to have the final grid connection, grid code settings and commissioning done by a certified installer.
