Offgridtec Solar-Direct 1800Wp HMT-2000-4T Solar System for 3-Phase Grid Connection

The Solar Direct all-in-one systems from Offgridtec (MPN 015570) are an ideal way to generate some of the electricity your household needs yourself and thus lower your electricity costs. The system includes four 450 W solar modules from Luxen Solar with a total output of 1,800 Wp, a Hoymiles HMT-2000-4T microinverter with 2,000 VA output power, and the necessary connection cables for professional installation. Our support team is here to assist you with advice and guidance on custom mounting options for the modules.

Highlights of the HMT Solar System:

• Scalable performance: With the appropriate technical design, the system can be expanded with additional compatible HMT units. The additional components and connection requirements needed for this must be verified on a case-by-case basis.
• Three-phase grid feed-in: Ideal for properties or commercial operations that have a high electrical base load during the day.

Important installation note: The solar system has a nominal inverter output of 2,000 VA and is not intended for standalone operation via a standard household outlet. Connection to the power grid and commissioning must be performed by a qualified electrician in accordance with applicable electrical regulations and technical connection requirements. The existing electrical installation must be checked for suitability before connection.

The 1,800W Solar-Direct Complete System includes:

• 4x Luxen Solar 450W bifacial solar modules TopCon N5 Full Black
• 1x Hoymiles HMT-2000-4T 3-phase micro-inverter

Installation and Grid Connection in Germany

The solar system has a nominal PV power of 1,800 Wp and a nominal inverter output power of 2,000 VA. This exceeds the 800 VA inverter power limit applicable to simplified plug-in solar devices, and the system must therefore be installed as a grid-connected PV system in accordance with applicable technical regulations.

The three-phase connection to the home electrical system and commissioning must be performed by a qualified electrician. The electrician will inspect the existing electrical installation and ensure a suitable, standards-compliant connection solution. This kit is not intended for self-commissioning by plugging it into a standard household outlet.

The system must be registered in accordance with applicable legal requirements and the requirements of the responsible grid operator. This includes, in particular, registration in the Federal Network Agency’s market master data registry.
