Features of storage battery facility with the new power conditioner

1.High degree of freedom in terms of locations of installation
Since transportation, carrying-in, and installation work can be performed for units of storage battery panels, no special vehicles or large cranes are required for installation.
Compared to the large container-type storage battery facilities that have become mainstream in recent years, this system offers much greater flexibility when it comes to the selection of the installation site, including in terms of transportation routes used at the time of installation, and can be installed in narrow areas.

2.High degree of freedom in terms of facility design
Flexible design support is possible by increasing or decreasing the quantity of storage battery panels according to the required storage battery capacity.
