Engineering answer
Select from the load backward.
Confirm the real connected load, phase, starting or inrush behaviour, power-quality requirement, target runtime where relevant, site conditions and future headroom before locking capacity or configuration.

Heavy-duty pure sine-wave inverter architecture for commercial, industrial, motor and emergency loads that require dependable outage backup.
How to select
Choose the right system before you choose the rating.
A heavy-duty inverter should be sized from real operating and starting demand, not only the arithmetic sum of nameplate watts. Fujitronix publishes its ARS 335 high-capacity platform with DSP control, IGBT switching and three-phase output across multiple ratings.
- Running load
- Motor / compressor starting current
- Input and output phase
- Backup duration
- Battery type and voltage
- Ambient and installation conditions
Commercial selection
What changes the final configuration and quote?
Provide connected and starting load, motor/compressor details, phase, expected outage duration, battery preference, operating environment and critical-load priority. These drive both inverter and battery selection.
System operation
Running load and starting load are two different sizing checks.
Motors, pumps, compressors and transformers can demand much more power for a short period than during normal operation. A proposal should show that the inverter can support both the continuous load and the expected starting sequence without excessive voltage drop or nuisance shutdown. Where several motors exist, define whether they start together or one after another.
Lifecycle planning
The battery, charger and inverter must remain matched over the full service life.
Backup time can fall because the load grows, batteries age or the charger is not set correctly. Routine checks should record operating load, DC voltage, battery/string condition, charger behaviour, cooling, alarms and connections. When batteries are changed, confirm chemistry, bank voltage, usable capacity, cable suitability and protection instead of copying only the old Ah label.
Site planning
Installation planning for heavy duty inverter.
Heavy-load backup must account for distribution, starting current and the battery/DC system—not just inverter placement. Cable sizing, protection, ventilation, motor behaviour, battery location and maintainability should be checked before final commissioning.

RFQ checklist
What to send before requesting a heavy duty inverter proposal.
Share connected and starting load, motor or compressor details, phase, expected outage duration, battery preference, operating environment, critical-load priority and any planned future load increase.
Fujitronix approach
A useful proposal should answer more than capacity.
Fujitronix combines requirement review, product selection, manufacturing and lifecycle service. For a useful proposal, share the load schedule, phase, backup objective, site conditions and any monitoring, bypass, battery or integration requirement. The quotation should clearly state the recommended system and what is included.
Buyer & engineering checklist
Four decisions that shape the heavy duty inverter proposal.
Clear answers at the enquiry stage reduce incorrect sizing, missing accessories and price comparisons between unlike systems.
What is the peak power requirement?
The inverter and battery must meet the highest simultaneous load and any starting surge, measured in kW or kVA.
How much energy is required?
Usable kWh is selected from the critical load, target hours, allowed depth of discharge and system losses.
Is solar part of the system?
Share PV capacity, MPPT/inverter details and the required grid/solar charging behaviour.
Can capacity be expanded later?
Expansion must be planned around compatible modules, BMS limits, inverter capacity and installation space.
Avoid weak specifications
Common mistakes that lead to the wrong quotation.
- 01Buying on Ah without checking battery voltage
- 02Ignoring BMS continuous and peak current
- 03Sizing energy without checking inverter power
- 04Assuming every lithium battery communicates with every inverter

Frequently asked questions
Clear answers before you shortlist a system.
Practical answers for purchase teams, consultants, facility managers and business owners planning a serious enquiry.
01What should I check before buying heavy duty inverter?+
Provide connected and starting load, motor/compressor details, phase, expected outage duration, battery preference, operating environment and critical-load priority. These drive both inverter and battery selection.
02What makes an inverter suitable for industrial loads?+
Industrial selection typically considers phase, surge current, motor starting behaviour, protection, duty cycle, battery architecture and maintainability in addition to the nominal kVA rating.
03Does Fujitronix publish 10 kVA industrial inverter capacity?+
Yes. The current ARS 335 product information lists 6, 8, 10, 15, 20, 30 and 50 kVA ratings.
04How is inverter backup time decided?+
Backup time is primarily a function of connected load, battery voltage and usable battery capacity, with system losses and discharge limits included in the engineering calculation.
05What should I send Fujitronix for a faster heavy duty inverter recommendation?+
Share connected and starting load, motor or compressor details, phase, expected outage duration, battery preference, operating environment, critical-load priority and any planned future load increase.
06Can heavy duty inverter be selected only from price or nominal rating?+
Not reliably. Provide connected and starting load, motor/compressor details, phase, expected outage duration, battery preference, operating environment and critical-load priority. These drive both inverter and battery selection. A comparable proposal should state the assumed load, topology, included battery or accessories, installation scope and the conditions used for sizing.
07What should be verified during installation or commissioning of heavy duty inverter?+
Heavy-load backup must account for distribution, starting current and the battery/DC system—not just inverter placement. Cable sizing, protection, ventilation, motor behaviour, battery location and maintainability should be checked before final commissioning. The exact commissioning checklist should follow the selected product documentation and project scope.
08Does Fujitronix support installation and after-sales service for heavy duty inverter?+
Yes. Fujitronix's supplied company profile lists consultation, installation, operator training, maintenance, battery replacement, upgrades, emergency support, and comprehensive or non-comprehensive AMC options. Final coverage, response and inclusions depend on the product, site and agreed commercial scope.
