01 / Define the objectiveStart with the business problem—not the cabinet size.
A commercial storage proposal changes substantially depending on whether the priority is critical-load backup, solar self-consumption, peak management, generator coordination or a combination of objectives. Define the operating priority and how success will be measured before selecting inverter power or battery energy.
Backup
List only the loads that must remain powered, their operating schedule and the required autonomy.
Solar self-consumption
Compare daytime solar production with the site's interval load profile and permitted export behavior.
Peak management
Identify when maximum demand occurs, its duration and the tariff or operating reason for reducing it.
Microgrid operation
Describe grid, generator, solar and storage operating modes plus the required transition and control logic.
Use interval data whenever it is available.
A monthly electricity total cannot show short demand peaks, simultaneous equipment operation or the time window in which storage is useful. Fifteen-minute or hourly data is a stronger starting point; measured power-quality and starting-current data may also be needed for motors, compressors and large transformers.
Minimum data
Site voltage, phase, frequency, maximum demand, daily energy and the critical-load list.
Preferred data
At least several representative weeks of interval load data, including high-demand and low-demand periods.
Surge loads
Record motor size, starting method, starting current and whether loads may start simultaneously.
Existing sources
Document PV capacity, generator rating, grid reliability, transformer and main switchboard information.
Size kW and kWh as two different requirements.
Inverter power in kilowatts must cover the required simultaneous load and operating strategy. Battery energy in kilowatt-hours must support the intended duration after allowing for the confirmed operating window, conversion losses, reserve, temperature and aging assumptions.
Inverter power
Check continuous demand, permitted overload, starting surge, phase arrangement and charge/discharge objectives.
Battery energy
Calculate load energy over the target period, then apply the confirmed usable-energy window and system losses.
SAVYEN public range
The HV76.8V314Ah platform uses 24.12 kWh modules, with public 6-11 module configurations of 144.69-265.27 kWh.
Project boundary
Published nominal capacity is not a guaranteed runtime; final usable energy depends on the selected system and settings.
The electrical room and switchboard are part of the system.
Commercial storage selection must account for the connection point, protection, isolation, earthing, cable routes, ventilation, access, fire strategy and local installation requirements. A qualified project team should confirm the single-line diagram and compliance scope.
Electrical
Single-line diagram, transformer, switchboard ratings, fault level, CT locations and protected-load arrangement.
Environment
Indoor or outdoor location, temperature, humidity, dust, altitude, drainage and available clearances.
Operations
Monitoring, remote access, alarms, maintenance access, shutdown procedure and responsible personnel.
Delivery
Destination, route, unloading method, door and corridor dimensions, floor loading and installation schedule.
Send one complete project brief for faster technical matching.
Project identity
Country, site type, application and current project stage.
Electrical data
Voltage, phase, frequency, maximum demand, interval load data and single-line diagram if available.
Operating target
Critical loads, required backup time, peak target, solar capacity and generator or grid behavior.
Commercial scope
Quantity, delivery location, schedule, documentation, branding and required compliance evidence.
