Temporary power is often required before a permanent grid connection is available. Road construction, bridge projects, remote industrial operations, telecommunications sites, and emergency response teams may all need a reliable electricity supply that can be deployed and relocated as project requirements change.
A trailer-mounted energy storage system provides a flexible approach to these situations by combining battery storage with power conversion, intelligent energy management, and, depending on the configuration, solar generation and diesel backup.
For project developers and equipment procurement teams, the main consideration is not simply battery capacity. The system must match the site's power demand, daily energy consumption, available power sources, transportation requirements, and expected operating period.
INJET New Energy develops the HanCang hybrid energy storage system for temporary power and distributed energy applications. The HanCang 261kWh integrates solar, battery storage, and diesel generation in a transportable solution designed for remote sites, telecommunications stations, and small off-grid facilities.
A trailer-mounted energy storage system is a transportable power solution that stores electrical energy and supplies it when required. Depending on the design, it can combine batteries, power conversion equipment, monitoring, energy management, and connections to other power sources.
Unlike a conventional stationary battery installation, a transportable system is designed with deployment and relocation in mind. This can be useful when a project moves between work areas or when a permanent electrical connection is not yet available.
A hybrid configuration may coordinate several energy sources:
Battery energy storage for supplying stored electricity
Solar photovoltaic generation when suitable sunlight is available
Diesel generation for additional energy supply when required
Grid electricity where a connection is available
An energy management system to coordinate power sources and loads
The precise configuration depends on the product model and project requirements. Buyers should confirm the transportation arrangement, installation method, output power, energy capacity, and compatible power sources before selecting a system.
Temporary power requirements can change substantially over a project's life cycle. A construction site may need electricity for site offices and lighting during one phase, followed by pumps, welding equipment, or other higher-demand equipment during another.
Installing permanent electrical infrastructure may not be practical for short-term projects or locations where grid connection is delayed.
A mobile energy storage system can provide another option by bringing an integrated power solution to the site. It may reduce the need for extensive temporary electrical infrastructure and allow the power system to be redeployed when the project moves.
The actual benefits depend on the site's electrical requirements, equipment configuration, operating schedule, and available energy sources. A mobile system is not automatically the lowest-cost option for every project, so a load assessment should come before equipment selection.
Construction projects may operate far from existing grid connections, particularly during early-stage infrastructure development.
A hybrid energy storage system can support temporary site facilities, lighting, pumps, and other electrical equipment. Solar generation can contribute energy when conditions allow, while battery storage helps balance supply and demand. A compatible generator or grid connection can provide additional power when required.
INJET's Road and Bridge Construction solution describes the use of hybrid power for temporary infrastructure projects, including sites where grid access is unavailable or connection timelines are prolonged.
Remote industrial operations may need electricity for monitoring equipment, site facilities, tools, and auxiliary systems.
In these environments, transportation, environmental conditions, maintenance access, and fuel logistics can all affect the power solution. A hybrid system should therefore be evaluated as part of the site's complete energy plan rather than as a standalone battery.
For locations with limited infrastructure, the ability to coordinate storage with solar generation and backup generation may offer greater operational flexibility than relying on a single energy source.
Telecommunications infrastructure may be located in areas where grid availability is limited or power reliability is a concern.
A hybrid energy storage system can be assessed for suitable telecom applications based on the site's continuous load, required autonomy, available solar resource, backup arrangements, and monitoring needs.
INJET lists telecommunications stations among the intended applications for its HanCang 261kWh system. The final configuration should be confirmed against the actual site's load profile and operating requirements.
Emergency teams may need temporary power for lighting, communications, medical support facilities, and other essential operations.
A transportable power solution can be useful when the permanent grid is unavailable, but emergency projects require particular attention to access routes, setup procedures, electrical safety, environmental conditions, and backup planning.
For emergency-response projects, buyers should also confirm how the equipment will be transported, connected, monitored, and maintained in the intended deployment environment.
A hybrid energy storage system coordinates energy sources according to the site's operating requirements.
In a solar-storage-diesel configuration, the control strategy may prioritize available solar power, use the battery to store or supply energy, and call on diesel generation when additional power or energy is needed.
A simplified operating sequence is:
Solar generation → Battery storage and energy management → Site loads
When solar generation is insufficient, the system may use stored energy or another configured power source. If the battery's available energy becomes insufficient for the required load, a compatible generator or grid connection can provide additional supply according to the system design.
The control strategy depends on the equipment and settings. Buyers should confirm whether the system supports the required operating modes, including grid-connected operation, off-grid operation, source switching, and remote monitoring.
INJET's HanCang 261kWh product is designed around a hybrid architecture that integrates solar, storage, diesel generation, grid input, and intelligent dispatching according to the configured application.
Selecting a suitable system requires more than matching a battery's kWh rating to an estimated daily energy figure.
Two measurements are particularly important:
Power capacity (kW): The rate at which the system can supply electricity.
Energy capacity (kWh): The amount of energy stored for use over time.
A site with several high-power machines may require substantial output power even if those machines operate for relatively short periods. A remote site with a modest continuous load may need more stored energy to support longer operating hours.
Before requesting a quotation, gather the following information.
List the equipment that may operate simultaneously and identify the highest expected load. Motors, pumps, compressors, and other equipment can have starting-current requirements that differ from their normal operating power.
The supplier should review both continuous demand and short-duration peaks.
Estimate or measure the site's total electricity use over a typical operating day.
If the project has different work phases, provide separate load estimates where possible. This helps the system designer account for changes in energy demand rather than relying on a single average figure.
Determine how long the system must operate between charging opportunities or generator support.
The required duration depends on daily consumption, battery operating limits, conversion losses, weather conditions, and the availability of alternative power sources.
Confirm whether the system will use solar PV, a diesel generator, grid electricity, or a combination of these sources.
The charging configuration affects the energy balance and the amount of stored energy available during periods of high demand or low renewable generation.
If the project may grow, ask whether the system supports additional storage capacity or parallel operation. Any expansion should remain within the manufacturer's approved configuration and electrical design.
INJET's HanCang 261kWh is positioned as a compact, transportable hybrid energy storage solution for temporary power and distributed applications.
According to the official HanCang 261kWh product page, the system integrates solar, energy storage, diesel generation, grid input, and intelligent dispatching. Its published battery capacity is 261.2kWh, with a rated AC output power of 125kW.
The product page also lists LiFePO4 battery cells, intelligent liquid cooling, remote monitoring, and built-in fire protection at the battery-pack level. The available configuration and technical limits should be checked against the current specification sheet before procurement.
This model may be considered for projects that need a transportable hybrid power solution, including selected remote sites, infrastructure applications, telecommunications facilities, and emergency-power requirements.
The correct system should still be determined from the actual load, operating duration, environmental conditions, charging arrangements, and site connection requirements.
For EPC contractors, equipment distributors, infrastructure developers, and industrial procurement teams, a technical review should cover the complete system rather than battery capacity alone.
Evaluation Item | Questions to Confirm |
|---|---|
Rated output power | Can the system support the site's continuous load? |
Peak load capability | Can it handle equipment starting and short-duration overloads? |
Battery capacity | Is the stored energy sufficient for the required operating duration? |
Charging sources | Are solar, grid, and generator inputs supported in the required configuration? |
Operating modes | Does the system support the intended grid-connected or off-grid operation? |
Transportation | What transport arrangement and lifting method are specified? |
Environmental protection | Are the enclosure and operating limits suitable for the site? |
Monitoring | Are local controls, remote monitoring, and fault alerts available? |
Safety systems | What battery protection, fire protection, and emergency shutdown features are provided? |
Maintenance | What inspections, service access, and spare parts are required? |
These details should be documented before the order is confirmed. A supplier should also clarify which items are standard, which are optional, and which require project-specific engineering.
A diesel generator and a battery-based hybrid system serve related but different functions. The appropriate choice depends on the site's operating profile and power supply strategy.
Consideration | Diesel Generator | Hybrid Energy Storage System |
|---|---|---|
Primary energy source | Diesel fuel | Stored electricity plus configured charging sources |
Power duration | Depends on fuel supply and generator operation | Depends on battery energy and available charging or backup sources |
Solar integration | Requires additional compatible equipment | Can integrate solar when supported by the system design |
Load management | Depends on generator controls and configuration | Can coordinate battery, solar, generator, and grid input when supported |
Relocation | Depends on generator and installation arrangement | Depends on the system's transport design |
Maintenance | Engine and fuel-system maintenance | Battery, power electronics, cooling, and associated system maintenance |
A hybrid system may reduce generator operating hours when renewable energy or stored electricity can meet part of the load. However, fuel savings, emissions reduction, and operating costs depend on the system configuration, local conditions, load profile, and energy management strategy.
For projects requiring long-duration power with limited charging opportunities, generator capacity and fuel logistics remain important considerations.
Transportability is only useful when the equipment can be delivered, positioned, connected, and commissioned safely at the destination.
Before ordering a trailer-mounted energy storage system, confirm the system's dimensions, total weight, transport arrangement, lifting points, site access, and unloading method.
The term “trailer-mounted” can refer to different product designs. Some systems are integrated with a road trailer, while others are transportable enclosures designed for trailer delivery and lifting into position. Buyers should verify the exact arrangement rather than assuming every unit can be towed directly on public roads.
The site plan should also cover:
Ground conditions and placement area
Access for transport and lifting equipment
Clearance for ventilation and maintenance
Electrical connections and grounding
Cable routing and protection
Emergency access and shutdown procedures
Local electrical and fire-safety requirements
INJET's product information lists trailer transport and flexible deployment for HanCang 261kWh, as well as lifting and forklift handling specifications. The required handling method should be confirmed using the current product documentation and site conditions.

It can provide temporary or mobile electricity for suitable construction sites, remote facilities, telecommunications stations, infrastructure projects, and emergency applications. The specific use depends on the system's power rating, energy capacity, available charging sources, and operating environment.
Some hybrid systems support off-grid operation by combining battery storage with configured power sources such as solar PV and diesel generation. Buyers should confirm the available operating modes for the selected model.
Start with the site's power demand, daily energy consumption, required operating duration, and charging opportunities. The supplier should then assess battery capacity and output power together.
Yes, where the system supports PV input or an appropriate solar integration configuration. Solar contribution depends on array capacity, sunlight conditions, system limits, and the site's energy demand.
No. Suitability depends on the site's peak load, energy use, equipment starting requirements, operating schedule, and available backup sources. A project assessment is needed before choosing a capacity.
Provide the application, load list, peak power, estimated daily energy use, required operating duration, available power sources, site conditions, delivery destination, and any relevant technical requirements.
A trailer-mounted energy storage system can provide a flexible power option for temporary projects where grid access is limited, delayed, or unavailable. The right solution depends on more than battery size: power demand, operating duration, charging sources, transportation, safety, and deployment requirements all need to be considered.
