A battery energy storage system holds power until you need it. Solar generated at noon runs your evening shift. Grid power bought cheaply overnight covers your peak. For most commercial sites the saving comes less from the energy itself than from the demand charge it avoids.
Storage is the piece that connects the two halves of Zenor. On a solar site it moves generation to where consumption actually sits. On an EV charging site it absorbs the draw of a fast charger, so a station can run high-power charging without the connected load – and the demand charge – that would otherwise require.

No. A battery earns its keep on grid power alone by charging when tariffs are low and discharging during your peak demand window. Pairing it with solar adds a second saving, but it is not a requirement.
That comes from your load profile, not from your connected load. We read twelve months of bills and your demand pattern, then size the battery against the peak it actually has to cover.
For many sites, yes. A battery takes over instantly with no start-up delay, no fuel and no noise. Whether it replaces the generator entirely depends on how long your outages last and what has to stay running.
Battery life is quoted in charge cycles rather than years, so it depends on how hard the system is worked. We give you the manufacturer's cycle warranty and what it means for your usage pattern before you commit.
