How to Build a Mobile Floor-standing Energy Storage System

 


Awesome—building your own mobile floor-standing energy storage system is a great project! Let’s break it into the key components and design steps so you know what to consider.

 System Overview

You’re essentially creating a modular battery-powered system that can:

  • Store energy (from solar, grid, etc.)
  • Deliver AC/DC power to various loads
  • Be moved when needed (but not carried)

 Core Components

1.  Battery Pack

  • Type: LiFePO₄ (preferred for safety, longevity, thermal stability)
  • Voltage: 48V is common for high-capacity systems
  • Capacity: Depends on use case (e.g., 5kWh, 10kWh, 15kWh)
  • Example: 16s configuration of 3.2V 100Ah cells = ~5.12kWh @ 48V

2.  Battery Management System (BMS)

  • Monitors voltage, current, temperature
  • Protects against overcharge, overdischarge, short circuit
  • Choose one rated for your battery pack (e.g., 16s BMS for 48V system)
  • Option: Smart BMS with Bluetooth or RS485/RS232 for monitoring

3.  Inverter (DC → AC)

  • Pure Sine Wave: For compatibility with sensitive electronics
  • Power rating: Match your load (e.g., 3000W, 5000W)
  • Many inverters include solar charge controllers

4.  Solar Charge Controller (optional)

  • If using solar, use MPPT (Maximum Power Point Tracking)
  • Match voltage and current to your solar panel specs

5.  AC/DC Output Ports

  • AC outlets (120V/230V) from inverter
  • USB ports, 12V DC ports for direct DC loads
  • Circuit breakers or fuses for safety

6.  Display & Monitoring

  • LCD or TFT display for system status
  • Optional Wi-Fi/Bluetooth for mobile monitoring
  • Smart meters for energy flow visualization

7.  Enclosure & Mobility

  • Metal or rugged ABS casing with proper ventilation
  • Wheels or castors for mobility
  • Handles or latches for transport
  • IP rating (dust/water protection) if used outdoors

8.  Safety Systems

  • Fuses or circuit breakers
  • Cooling (passive or active fans)
  • Grounding system
  • Optional smoke or thermal sensors

 Example Build: 10kWh / 48V System

ComponentExample Spec
Battery Cells16 × 3.2V 200Ah LiFePO₄
BMS16s 200A Smart BMS
Inverter5000W Pure Sine Wave Inverter
EnclosureSteel frame w/ wheels
DisplaySmart LCD or TFT w/ sensors
Ports2×AC, 2×USB, 1×12VDC
Charge SourceGrid + Solar (optional MPPT)

 Planning Considerations

  • Use Case: Backup power? Mobile workbench? Outdoor events?
  • Daily Load Profile: How many kWh/day do you need?
  • Portability vs Capacity: More energy = more weight
  • Budget: LiFePO₄ isn’t cheap, but it’s worth it long-term

 Next Steps

If you’d like, I can help you:

  • Size your battery based on your energy needs
  • Sketch a wiring diagram
  • Pick specific parts (cells, BMS, inverter, etc.)
  • Plan the layout for airflow, wiring, and accessibility

Just tell me more about:

  • What you’ll use it for
  • How many devices or watts you need to power
  • Whether you want solar or grid-only charging

Let’s build something awesome!

Issues to consider when installing wall-mounted energy storage batteries

Installing a wall-mounted energy storage battery is a task that requires careful planning and execution. Here are some issues to consider: 1. Safety: - Battery type: Choose a battery type with high safety, such as lithium iron phosphate batteries. - Fire prevention measures: Make sure the installation area has fire prevention measures and complies with local fire regulations. 2. Installation location: - Ventilation: Choose a well-ventilated location to avoid overheating of the battery. - Waterproof: Avoid installing in places where water is easily ingressed. - Space: Make sure there is enough space for installation and maintenance. 3. Structural requirements: - Wall load-bearing: Make sure the wall can bear the weight of the battery. - Fixing method: Use appropriate fixing brackets and bolts to ensure that the battery is firmly installed. 4. Electrical connection: - Line design: Plan the connection lines between the battery, inverter, and grid to avoid voltage loss caused by too long ...

The Ultimate Guide to RV Batteries

图片
When it comes to powering your RV adventures, having the right batteries is crucial. Here is the ultimate guide to RV batteries to help you make informed decisions: Types of RV Batteries : Lead-Acid Batteries : Traditional and cost-effective, available in two types: flooded (wet cell) and sealed (AGM, gel). Lithium Batteries : Lightweight, high-performance, longer lifespan, but more expensive upfront. Gel Cell Batteries : Sealed and maintenance-free, resistant to vibration, suitable for deep cycling. Battery Capacity : Amp-Hour (Ah) Rating : Indicates the amount of energy a battery can store. Higher Ah means more capacity. Consider Usage : Calculate your daily power consumption to determine the capacity needed for your RV. Battery Maintenance : Regular Inspections : Check for corrosion, loose connections, and electrolyte levels in lead-acid batteries. Proper Charging : Follow manufacturer guidelines for charging lithium-ion batteries to maximize lifespan. Charging Systems : Converter :...
