What this model can do
Shave power peaks
An industrial site is billed on the highest peak measured during the month. Starting machines or a chiller is enough to push it up. The battery covers the excess instead of the grid.
Consume your own generation
Electricity generated in the middle of the day by a photovoltaic system is used in the evening, instead of being exported to the grid.
Arbitrage the price of electricity
Charge when electricity is cheap, discharge when it is expensive. The on-board control system decides, based on prices and on your load curve, with no intervention.
Run without the grid
The Mercury units operate grid-connected or off-grid. Changeover and back-up power are defined at configuration.
Charge fast without upgrading the connection
A fast charger draws power that a site’s grid connection cannot always supply. The battery acts as a buffer between the grid and the charger.
Support a solar farm
On a new or an existing plant, storage smooths generation, shifts export and holds the power committed to the grid operator.
Pair it with a fast charger
A DC charger draws power that a site’s grid connection cannot always supply. The battery acts as a buffer.
