"The BOX"

BOX DESCRIPTION

The BOX, currently in patent-pending status, is a power station comprising 2 separable elements: a hybrid inverter and a modular lithium battery. 

Both elements are flat-shaped and separable, and the top handles make them easy adaptable to both operation modes. In portable mode, both elements are assembled together on a trolley. In home mode both elements are mounted on the wall close to the electrical board and connected to power home circuits. 

Two lateral connection boxes in the battery make them modular in both operation modes. 

In portable mode battery modules are piled one in front of the other and connected in parallel by cable through same side connection boxes. In home mode battery modules are mounted on the wall side by side and connected through adjacent connection boxes.

The swapping from one mode to the other is easily done by the user is just 1 minute and with no tools.

Technical characteristics

The hybrid inverter apart from providing the AC output to power the loads includes a DC input/output connection for the battery, an AC input for the grid and a DC input for the PV panels. This DC input is internally connected to an MPPT controller that maximizes the PV panels performance. The connectivity is completed with Wi-fi and serial port communication to monitor all the energy parameters. The hybrid term of the inverter refers to the capacity to work in several operation modes depending on the priority given to either the PV generation or the grid, and the configured charge thresholds of the battery. 

2 battery coatings of different sizes have been designed to hold 2 lithium-ion technologies (Lithium Iron Phosphate - LFP and Nickel Manganese Cobalt - NMC), in combination with up to 3 different inverter powers of 24 and 48V configurations.
