Plug&play installation
The cabinet structure is easy to transport and install directly at the site. This avoids the need for on-site assembly and makes installation much quicker.

Cost reduction
This solution is designed to guarantee maximum energy efficiency without the need for air conditioning with outside temperatures of up to 50C. Air-conditioned cabinets are however available upon request. These include a specific air conditioning unit for each inverter and are recommended when installed in particularly hot places to prevent power limitations due to eternal overtemperatures. Air conditioning
functions include: free cooling, cooling, anti-condensation.

Modularity and flexibility
A modular solution with possible power upgrades up to a maximum of four 330 kW inverters. Optional accessories are also available to configure systems to meet the full range of customer requirements.

Accessibility
Cabinets are supplied as turnkey solutions and are specifically designed to ensure access to all internal components and inverters, to facilitate inspection and servicing.
