Czech Republic Goes Green: Growatt MID 30KTL3-XH Inverters and APX HV Batteries in Modern Green Offices

The Czech Republic is experiencing a renewed focus on solar energy adoption, driven by government initiatives and EU funding. After a period of slower growth, the country is revitalising its solar sector to address rising energy costs and enhance energy independence.

Government Support and Funding

In 2023, the Czech Republic secured CZK 55 billion from the European Union's Modernisation Fund to expand the New Green Savings (Nová Zelená úsporám) initiative. This funding aims to support both residential and commercial solar projects, making renewable energy more accessible and affordable. The initiative encourages energy-efficient renovations, including solar panel installations and energy storage systems.

Project Overview: 49.1kW Solar Energy Storage System by a Czech Office

With increasing government support for solar, a Czech office installed a comprehensive Growatt Commercial and Industrial Energy Storage System designed to achieve self-sufficiency.

The project details include:

Inverters: 2x Growatt MID30KTL3-XH (60 kW total capacity)

Battery System: Growatt APX HV (100 kWh total capacity)

Backup System: 2x Growatt SYN backup boxes

Solar Array: 49.1 kWp, oriented East/West

EV Charging Stations: 6x THOR 22 kW AC chargers (132 kW total capacity)

This customer can expect to generate approximately 49,100 kWh of energy annually with Growatt's energy storage system, significantly reducing their reliance on grid electricity and moving towards energy self-sufficiency. Furthermore, they can utilise the surplus energy to power their electric vehicles with THOR EV Chargers, forming a comprehensive energy storage system to power the office and electric vehicles.

Future-proofed C&I Energy Storage System: MID 30KTL3 XH Inverters + APX HV Batteries

The Growatt MID 30KTL3-XH inverter boasts a maximum efficiency of 98.6%, making it one of the most efficient C&I inverters on the market. It integrates seamlessly with high-voltage solar batteries like the APX HV series, supporting up to 30 kWh per unit and scalable up to 180 kWh with multiple units. This combination is ideal for businesses seeking a high-powered energy storage system to meet their substantial energy demands.

Key Features of MID 30KTL3-XH Inverters:

Maximum Efficiency: 98.6%

Type II Surge Protection: Available on both DC and AC sides for enhanced safety.
