The System
Solar, storage & power conversion in one container
The Polinovel Mobile Solar Container with BESS is engineered as a complete, transportable microgrid rather than a bundle of separate parts. A 144 kWp foldable solar array feeds a 261 kWh cabinet-type LFP battery through a 125 kW PCS, while liquid cooling and integrated protection keep the high-value battery safe in harsh outdoor conditions.
Because it uses cabinet-level storage instead of a large containerized battery, the footprint stays compact and easy to arrange in limited project spaces - and the modular build simplifies transport, installation, and site setup. As a manufacturer and OEM/ODM partner, Polinovel configures capacity, voltage, and the optional diesel and EV-charging interfaces around your load and site.
- Foldable PV array - 144 kWp, 720 W modules, fast on-site solar deployment.

Disadvantages of operating diesel fuel at remote sites
Off-grid and temporary projects share the same power problems.
The Mobile Solar Container with BESS is built to solve them in one transportable unit.
No grid, or a weak one
Mining sites, oilfields, islands, and new construction often have no utility connection - or an unstable one that can't carry the load reliably.
Slow, complex site installation
Sourcing and wiring PV, batteries, and conversion gear separately invites delays and field rework - a real risk where skilled labour is scarce.
Diesel cost, logistics & noise
Fuel price swings, remote-haul logistics, refuelling labour, emissions, and round-the-clock generator noise stack up fast on long-running sites.
Mixed AC and DC demands
Many sites need general AC loads kept alive and, increasingly, DC fast-charging for vehicles or equipment - without two separate systems.
Quality & Safety
Engineered around the battery's safety
The Mobile Solar Container with BESS is built around LFP chemistry, liquid cooling, and integrated protection so the highest-risk subsystem stays within a safe operating window.
LFP 314 Ah cells are managed for charge/discharge control and balancing, liquid cooling holds battery temperature across a −30 to +55 °C range, and IP55/IP54 protection guards against dust and moisture on harsh outdoor sites. The system is designed to meet the standards typically required for solar and BESS projects, and compliance documentation and test reports can be provided on request - final compliance for your market should be confirmed before shipment.

FAQ
Q: What is the Mobile Solar Container with BESS?
A: It is a compact solar battery microgrid that combines a 144 kWp foldable solar array, 261 kWh of liquid-cooled LFP storage, and a 125 kW PCS in one transportable 20HQ unit, with optional diesel-generator access and an EV-charging interface. Polinovel configures it for off-grid, weak-grid, and temporary power on remote and mobile sites.
Q: Can it run off-grid?
A: Yes - off-grid operation is supported as an option via an external 125 kW hybrid inverter, alongside the standard grid-tied PCS. A reserved diesel-genset interface also allows hybrid operation, so the unit can run standalone, supplement an existing supply, or work with a generator depending on your site strategy.
Q: Does it include EV charging and diesel backup?
A: Both are optional interfaces. The EV-charging module provides 120 kW over a 200–1000 V range with one coupler, and the diesel interface uses a reserved DG connection with an added AC distribution cabinet (supported by the hybrid inverter). Specify the options you need at quotation and Polinovel will configure them.
Q: What loads can it support?
A: The system is designed for small and medium loads rather than a large-scale power plant. The 125 kW PCS covers general AC loads, while 261 kWh of storage sets the available backup energy. Send your load list and required backup hours and our engineers will confirm whether the standard configuration fits or recommend an adjustment.
Q: Can the capacity or voltage be customised?
A: Yes. As a manufacturer and OEM/ODM partner, Polinovel can adjust PV and storage capacity, PCS configuration, AC voltage/frequency (230/400 V, 50/60 Hz standard), and the optional diesel and EV interfaces to suit your project, climate, and standards.
Q: What is the MOQ and lead time?
A: Because each system is project-engineered, the minimum order is typically a single unit, with project and program pricing for multiple units. Lead time depends on configuration and customisation and is confirmed at quotation - please share your required delivery date and destination so production and shipping can be planned.
Q: Can you provide datasheets, test reports, and certifications?
A: A product datasheet is available, and pre-shipment test records can be provided on request to support engineering review and acceptance. The system is designed to meet the standards typically required for solar and BESS projects; available compliance documents can be supplied, and final compliance for your market should be confirmed before shipment.
Q: Can you provide export-ready packaging?
A: Yes. Systems are packaged export-ready for sea freight, and packaging or branding can be customised for OEM and distributor requirements. Confirm your destination port, Incoterms, and documentation needs early so delivery can be planned smoothly.
Q: What information is needed for a quotation?
A: Please provide your load list, daily operating hours, project location, grid availability, required backup time, voltage/frequency, site environment (temperature, altitude), whether you need diesel or EV-charging options, and your target delivery schedule. With this, Polinovel returns a project-specific configuration and quote.
Q: How do I choose the right configuration?
A: Start from your critical loads and required backup hours, then add site conditions and whether you need off-grid, diesel-hybrid, or EV-charging capability. Use the model selection guide or send your load profile, and Polinovel will recommend a configuration with the right PV, storage, and PCS setup.
