Growatt MOD 8000 TL3-XH – 8kW Three-Phase Hybrid Inverter

The Growatt MOD 8000 TL3-XH is a premium 8kW three-phase hybrid inverter engineered for high-performance solar PV systems in the UK. Designed for homes and light-commercial applications with larger roof arrays, it offers exceptional energy conversion, robust safety compliance, and seamless readiness for high-voltage battery integration. As part of Growatt’s trusted MOD TL3-XH series, it provides long-term stability and flexibility for scalable renewable systems.

High-Efficiency Performance for British PV Systems

With dual MPPT trackers and a broad 140–1000V input range, the MOD 8000 TL3-XH maximises generation from complex or multi-aspect installations. It achieves an impressive 98.4% peak efficiency, ensuring that even under cloudy or low-light conditions, energy production remains steady and consistent. Growatt’s advanced MPPT algorithm maintains near-instant tracking accuracy (99%), helping installers deliver stronger yield performance in typical UK weather.

The inverter’s three-phase output provides balanced load distribution and stable grid interaction, making it particularly suited to small businesses and large residential properties with higher daytime demand.

Built for Reliability & Protection

Engineered with a durable IP66-rated aluminium casing, the MOD 8000 TL3-XH offers full protection from dust and heavy rain — perfect for British outdoor environments. Its natural convection cooling keeps operation silent below 25dB, with no need for fan maintenance. Built-in Type II surge protection (DC side), residual-current monitoring and insulation resistance detection further enhance system safety.

The inverter is fully compliant with G99 and certified to EN 62109 safety standards, ensuring reliable grid connectivity and peace of mind for installers and system owners alike.

Seamless Integration with Solar Panels & Battery Storage

The Growatt MOD 8000 TL3-XH is designed for seamless integration with solar panels and battery storage systems, offering full compatibility with Growatt’s high-voltage LFP technology. Using direct DC coupling, it minimises energy loss and accelerates charging response, allowing efficient transfer between PV generation and storage. Installers can connect up to seven modules in series for scalable capacity, delivering up to 28kWh of storage for homes or small businesses with higher energy usage.

This hybrid-ready system allows you to start as a grid-tied inverter and easily add batteries later — ideal for those planning to upgrade to full self-consumption in the future.

Smart Monitoring & Communication

Real-time performance tracking comes standard through Wi-Fi and LAN connections, with optional 4G modules for remote installations. The Growatt ShinePhone app and Smart Energy Manager platform provide detailed visibility into generation, storage levels, and consumption trends, making system optimisation simple for both owners and installers. Data logging is built in, while RS485, CAN, USB and DRM ports ensure smooth communication with battery management systems and export meters.

Compact Design & Rugged Construction

At just 480×448×180mm and approximately 20kg, the Growatt MOD 8000 TL3-XH balances power density with an installer-friendly design. The robust aluminium housing is fully IP66-rated to withstand the wet and variable British climate, while its fanless cooling keeps noise under 25dB for silent running. The clean external profile and simple bracket system allow easy wall mounting indoors or outdoors.
