Backup power for manufacturing
For owners, process specialists and energy engineers
Backup power for manufacturing
Define the process to support, the acceptable interruption and recovery sequence. We select Sungrow using workshop demand, allowing for a generator, solar or grid charging.
From equipment to a production objective
Which area needs support?
Continued operation and a controlled stop are different tasks. Agree the required outcome with process specialists and equipment manufacturers.
Metalworking and CNC
Check machines, auxiliary drives, cooling and controllers. Agree permitted interruption and stop or restart procedures for the actual line.
Polymer processes
Identify circulation, cooling, controls and agreed drives. Assess electrical and thermal needs separately with the process specialist.
Packaging and late shifts
Assess packaging machines, feeding, compressed air and records. For operation after the solar peak, verify actual surplus and battery charge.
Building materials, glass and ceramics
Identify electrical areas, controls and drives. Their backup is not equivalent to supplying every thermal process or furnace.
An agreed engineering brief
Tie backup to the workshop’s task
Describe outage behaviour, responsibility and acceptance criteria. Equipment procurement then has a verifiable production objective.
A clear priority
Identify the line or unit to support first. Check dependencies on compressors, pumps, cooling and control networks.
Verified starting demands
Running demand does not reveal every short peak. Include simultaneous starts and possible restart sequencing.
Protected reserve
Daily storage use must not consume the emergency reserve without control. Agree minimum charge and mode priorities.
A testable result
Define tests for grid loss, source transfer, agreed operation or stopping, and return to the normal shift.
Design around the process
From permitted interruption to backup mode
Energy needs and transfer design depend on the actual process. Storage can operate without solar when charging is available.
01. Define line behaviour
For each unit, specify continued operation, auxiliary support or a controlled stop. Record permitted interruptions.
02. Measure the workshop profile
Measure demand, starts and energy per shift. Assess seasonal peaks and simultaneous machinery separately.
03. Coordinate the sources
Check grid supply, generator, controls, UPS and solar. Protection and controls must support the agreed islanded mode.
04. Confirm recharge and reserve
Define charging between outages. Include losses and emergency charge when assessing tariff operation or solar surplus shifting.
Continuous controllers and sensitive equipment may need a separate UPS. Engineering checks and commissioning tests confirm suitability for the agreed backup mode.
Power and energy serve different purposes
Compare Sungrow against workshop demand
Assess PowerStack for a defined compatible group and PowerTitan for larger scale. Demand profiles and electrical design determine the choice, not the industry label alone.
Sungrow PowerStack 510CS-4H
- Rated AC output
- 125 kW
- Nominal battery capacity
- 514 kWh
PowerStack ST510CS-4H: nominal 125 kW and 514 kWh. Compare a larger energy reserve at the same nominal power.
Sungrow PowerTitan 2.0 ESS
- Output depends on configuration
- up to 2.5 MW
- Nominal battery capacity
- 5,015 kWh
5,015 kWh nominal capacity. Configurations up to 2,500 kW (2h) or 1,250 kW (4h) describe the specified system variant, not guaranteed site backup duration.
Assess PowerTitan 2.0 for larger industrial demand. The project defines connections, voltage conversion, sources and protection.
Nominal specifications do not establish continuity for a particular manufacturing cycle.
Kilowatts for running and starting
Compare simultaneous demand, short starts and the selected configuration’s capabilities. Adjust starting order where appropriate.
Kilowatt-hours for the process
Calculate energy over the agreed period, including losses and available charge. More energy cannot replace required power.
Integration into the plant
Define connections, foundations, protection, routes and service access. Coordinate installation windows with production.
A budget tied to the production task
What belongs in your area’s solution?
Compare quotations using the same process mode and work boundaries. Include required integration as well as the battery.
Current plant operation
Collect bills, profiles, generator costs and substantiated downtime effects. Check tariff scheduling against the electricity supply contract.
Implementation and operation
Equipment, connections, controls, enabling works, installation, tests and service. Define machine or process-line modifications separately.
Economics include losses, battery life and backup priority. Do not assume lower tariffs, defect-free output or payback without substantiated data.
Dedicated solution for printing plantsFrom engineering discussion to commissioning
Commission against agreed operating modes
The energy engineer, process specialist and operator help define the brief and accept the result.
01
Survey the production area
Collect drawings, measurements, machine requirements and permitted pauses. Agree the priority process and acceptance criteria.
02
Design and budget
Define configuration, protection, controls and location. Agree equipment supply and responsibilities with other contractors.
03
Install in the agreed window
Prepare infrastructure and connect equipment to the agreed plan. Conduct tests with the production team ready.
04
Acceptance and operations
Check sources, charging and process behaviour. Provide records, settings, monitoring procedures and agreed service terms.

Materials for an engineering meeting
A presentation for your production task
Describe output, the priority area and available measurements. We clarify these before preparing a solution.
Process and backup criteria
Required line behaviour, permissible interruptions, auxiliary systems and questions for machine manufacturers.
Configuration and delivery
Sungrow comparison, source integration, work boundaries and commissioning scenarios. Tie specifications and budget to the brief.
Production team questions
What should be checked before selection?
An industry name cannot determine transfer requirements, power demand or safe process completion.
Can we back up only a priority production area?
Yes, after checking its dependencies. Compressors, cooling, feeding and controls may sit outside the line itself. Define scope by the required function, not just the workshop boundary.
Will CNC continue operating through an outage?
That depends on allowable interruption, controller and drive supply, and machine manufacturer requirements. Agree continued operation or controlled stopping and test the scenario. Storage alone does not guarantee cycle preservation.
What needs backup in polymer manufacturing?
The process specialist identifies cooling, circulation, controls and drives, and the behaviour of the thermal process. Do not include every heater automatically. Check electrical scope and permitted interruptions.
Can the solution support packaging?
Assess actual packaging machines, feeding, compressed air, records and dependencies. A late shift may use verified solar surplus. Measurements and an emergency reserve are required.
Does backup cover furnaces and the entire materials plant?
Only if explicitly calculated and agreed. Control or drive backup does not supply all thermal needs. Glass, ceramics and other materials require their own process brief.
How can storage work with a generator?
Use the actual model, wiring and controls. Check transfers, protection, charging and permitted interaction. Parallel operation requires confirmed compatibility.
Can the system work without solar?
Yes, if suitable grid charging or an agreed alternative source is available. Check whether the reserve can be restored between required backup periods.
Will the battery replace UPS?
Not automatically. Check allowable interruptions for sensitive controllers and networks. Where continuous power is required, design appropriate UPS arrangements coordinated with storage.
How can daily tariff operation preserve emergency charge?
Define minimum charge and backup priority. Assess daily cycling using the supply contract, demand, losses and battery life. Economic scheduling must remain compatible with the agreed backup task.
How should we choose PowerStack or PowerTitan?
Use simultaneous power, starts, process energy and connection design. More energy does not automatically mean more power. The 2h and 4h specifications are not workshop runtime guarantees.
How are installation, warranty and service agreed?
Define the location, foundations, cables, access and production windows. The contract specifies works, tests, warranties, service and responsibility for adjacent equipment. Check placement against manufacturer requirements.
Which data is needed for the technical meeting?
Production type, location, drawings, machine list, demand profile, starts and permitted interruptions. Add generator and solar data, bills, expansion plans and a process specialist contact.
