Designed for sites with on-site solar generation, Polinovel’s semi-solid-state energy storage cabinet brings PV connection and battery storage into a single outdoor unit. It gives commercial and industrial customers a way to store solar energy for later on-site use, with the system configuration matched to their PV array and load requirements. The compact cabinet format also makes it easier to plan where the system will sit within an existing facility.
Polinovel’s outdoor energy storage cabinet brings battery storage, solar PV input, and outdoor deployment into one system.
1
Built with semi-solid-state battery cells for commercial and industrial energy storage projects.
2
Four independent MPPTs and up to eight PV string inputs give installers room to plan the connections around the site’s solar array.
3
The IP55 enclosure, air cooling, and −20°C to +50°C operating range give project teams clear conditions for assessing an outdoor installation.

For commercial and industrial sites planning solar PV and battery storage, the right cabinet configuration depends on more than system capacity. PV layout, on-site loads, and installation conditions all need to be considered.
Factory rooftops can provide space for PV panels, while the battery cabinet is installed outdoors at ground level. When evaluating a project, check the distance between the PV array and cabinet, available installation space, and the facility’s daily load profile.
For offices, retail facilities, and other commercial buildings, the cabinet can be assessed as part of a solar-plus-storage installation. The starting point is how much solar power the site produces, when the building uses electricity, and where outdoor equipment can be placed.
Solar PV connects to the outdoor energy storage cabinet through its PV inputs. When generation exceeds the site’s immediate needs, energy can be stored in the cabinet’s battery and used later as demand changes or sunlight fades. The system connects this solar input and stored energy to the facility’s AC loads, helping the site make more use of its own PV generation.
The IP55 cabinet is designed for outdoor installation and operates from −20°C to +50°C. C3 corrosion resistance is standard, with C4 and C5 grades available for sites with more demanding conditions.
Integrated air cooling helps manage heat inside the cabinet during operation. The enclosure’s ventilation design supports operation across the specified outdoor temperature range.
An aerosol and water fire suppression option is listed for the cabinet. Its configuration can be matched to the project’s fire protection requirements.
