Backup power for printing plants
For print shops and printed-packaging manufacturers
Backup power for printing plants
A print run depends on the whole production chain. We design backup power for printing plants with Sungrow equipment for agreed printing and finishing processes, ventilation and controls, from site assessment to operating tests.
Where an interruption affects the job
Include the press and its supporting processes
A stopped press, dryer or finishing line has different consequences. Work with the process team to define dependencies, interruption limits and the response for each line.
Printing presses
Drives, feeding, controls and auxiliary units. Assess production duty, makeready and the conditions needed to resume the job.
Drying and cooling
IR, hot-air, UV or LED UV systems where fitted. Identify dryer technology, electrical demand, cooling and extraction requirements.
Postpress operations
Cutting, folding, die-cutting, laminating or gluing. Select operations according to the job route and simultaneous use of equipment.
Air, extraction and automation
Compressors, ventilation, controllers and job systems. Establish what must remain active when the main drives stop.
For production and commercial decision-makers
Build the backup brief around the print job
The objective may be to finish an agreed operation, retain supporting functions or supply a selected line. Establish that objective before choosing battery capacity.
A defined response to interruption
Agree where cycle completion is feasible and where stopping is required. Check machine-manufacturer supply requirements with the process team.
Evidence of job disruption
The print shop supplies records of repeat makeready, material losses and delays. Use validated figures when comparing scenarios.
Room for equipment changes
Another printing unit, dryer or finishing line changes demand. Review the new operating profile before extending the storage system.
Day and night shifts
Assess solar against daytime self-consumption and backup against critical-job schedules. Night production cannot be treated as solar-hour demand.
From the distribution board to the operating brief
Coordinate power across the production chain
Press power alone does not describe the complete line. The design includes dependent units, sensitive controls, source transfer and recovery after an interruption.
01. Define the backup boundary
Map presses, dryers and supporting systems on the electrical diagram. Identify the functions required for each operating scenario.
02. Capture electrical operating modes
Measure printing, makeready, starts and drying demand. Review controller interruption limits and any dedicated UPS requirement.
03. Coordinate sources and protection
Review storage, the existing generator, controls and the grid. The selected electrical arrangement must support the intended island mode.
04. Test the return to production
Check the auxiliary and machine restart sequence, control recovery and charging. Avoid an unplanned simultaneous restart.
Storage does not replace process interlocks or guarantee uninterrupted printing. Machine documentation and the print-plant team define interruption limits and shutdown procedures.
Sungrow matched to print-plant scale
Select storage around lines and shifts
Assess PowerStack for defined loads. Consider PowerTitan 2.0 for a large printing site with suitable aggregate demand, grid connection and installation space.
Sungrow PowerStack 510CS-4H
- Rated AC output
- 125 kW
- Nominal battery capacity
- 514 kWh
125 kW and 514 kWh. More nominal stored energy for the agreed load. Doubling capacity does not mean twice as many presses can operate simultaneously.
Sungrow PowerTitan 2.0 ESS
- Output depends on configuration
- up to 2.5 MW
- Nominal battery capacity
- 5,015 kWh
Configurations: 2,500 kW (2h) or 1,250 kW (4h). These labels describe equipment, not guaranteed running time for your print job.
A container system for a large printing or packaging complex. Connection, island operation and the utility site need separate engineering checks. This is not a default package for every print shop.
These are nominal equipment ratings. Suitability for your line, usable energy and backup duration require the actual project inputs.
Dryer operating modes
Account for makeready, printing and standby separately. Heating, cooling and extraction belong in the agreed demand profile.
Combined electrical demand
Compare concurrent presses, compressors and finishing lines. Check brief peaks separately from average consumption.
An engineered energy area
Plan siting around paper, inks, dust, cables and maintenance access. Verify the actual conditions at the site.
Financial assessment from print-plant evidence
Compare investment with your operating scenario
Compare options using the same machine list and operating duty. Separate the costs of backup, self-generation and electrical-network modifications.
Your production inputs
Job schedules, shifts, measured demand, interruption limits and budget. The business validates the effects of stoppages and repeat makeready.
An agreed quotation scope
Equipment, transfer, boards, cable routes, site preparation and commissioning. Identify service terms, VAT, currency and quotation validity separately.
Pricing and financial scenarios follow an enquiry and data collection. Include electricity-contract terms, losses and battery life. Lower peaks do not automatically mean a lower tariff.
Implementation around the job schedule
Connect during an agreed production window
Agree access, production interruptions and test criteria before installation. Include printing, electrical and site teams in the preparation.
01
Review schedules and machines
Collect printing, finishing, drying and ventilation data. Identify operating modes that need measurement.
02
Approve the electrical design
Record backed-up circuits, equipment, sources and location. Prepare a quotation and scenario-specific acceptance criteria.
03
Install around planned work
Schedule site preparation and connection around plant operations. Agree any required shutdown before work begins.
04
Test the cycle and recovery
Test agreed duties, transfer and restart. Hand over documentation and confirm the service arrangement.

Questions from printing businesses
What to clarify before backing up a print plant
Line boundaries, drying, controls and generators. Use these answers to prepare a technical enquiry.
Can backup cover just one printing press?
That boundary can be considered, but first check drying, cooling, feeding, compressed air and control dependencies. The dedicated circuit must include every function needed for the agreed operation. Diagrams and measurements determine the final scope.
Does a battery guarantee an uninterrupted print run?
No. It depends on the machine’s interruption limit, transfer design, load and usable energy. The objective may be completion of an individual operation or a controlled stop. Agree the conditions with the process team and test them at commissioning.
How are UV, LED UV and other dryers assessed?
Use the actual technology and model. Electrical ratings, operating modes, cooling and ventilation are required. Where an external heat source is used, electrical backup does not replace it. Do not apply one dryer’s consumption to all technologies.
Why include a postpress line?
Include it when required by the agreed job route. Cutters, folders, die-cutters and other finishing machines have their own duty and drives. Check whether they operate alongside printing and which steps can be deferred.
Do printing controls require a UPS?
Review controller and press-manufacturer requirements. If the permitted interruption is shorter than the selected transfer can provide, a separate continuous-supply solution is needed. Assess storage and UPS equipment for their different roles.
How many hours can Sungrow support the plant?
Establish the machine list, work schedule and usable energy first. Include charge state, losses, dryers and auxiliary equipment. The 2h or 4h equipment designation does not promise a printing duration for your line.
Can we use the generator already installed?
Assess its rating, condition, controls and existing wiring. The design defines transfer, load allocation and potential storage charging. Parallel or island operation must use a verified configuration.
What inputs should a printing business provide?
Printing schedules, machine inventories, finishing-line power and the conditions for completing and restarting a cycle. Add supply diagrams, dryer and ventilation details, generator data and measured consumption. Identify future equipment demand separately as a forecast.
Is solar worth assessing when we run night shifts?
Review daytime demand, annual schedules, available space and connection conditions. Night operation affects the model but does not determine it alone. Standard grid-tied solar without a backup architecture cannot supply an outage.
Where should storage be installed at a printing site?
Check the location against equipment documentation and site conditions. Consider paper, inks, dust, vehicle movement, engineering clearances and maintenance access. For leased premises, clarify usage rights and occupancy duration.
When can we receive a quotation and payback assessment?
After an enquiry, an agreed operating brief and data collection. The financial model includes the complete works, operation, battery life and electricity-contract terms. The print shop validates downtime impacts; there is no universal payback period.
How are warranty and support arranged?
The proposal records equipment and installation warranties. Separately agree monitoring, planned inspections, contact procedures and response times. Handover includes documentation and operating-test results.
