Applications
The FLEXpower ONE is intended for on-grid, off-grid, and grid-interactive applications. It is
designed to use photovoltaic (PV) panels to harvest solar energy and a battery bank to store the
harvested energy.
On-Grid Applications
In on-grid applications, the FLEXpower ONE can use the grid power as the primary power source or as
the backup source of power. If the FLEXpower ONE is used as backup to the grid, the FLEXpower ONE
will take over when the grid fails. If the FLEXpower ONE is used as the primary source, the grid power
will be used when the batteries have been drained. In this situation, the AC power or PV harvest can
be used to recharge the battery bank.
