Earthing is a critical safety feature in Uninterruptible Power Supply (UPS) systems

TECHNOLOGY BLOGS

Earthing (or grounding) is a critical safety feature in Uninterruptible Power Supply (UPS) systems. It ensures the safe operation of the UPS and connected devices by providing a path for fault currents to dissipate into the ground, preventing electric shock, equipment damage, and fire hazards. The earthing connection in the UPS back panel is a key part of this system.

Back panel of UPS

Purpose of Earthing in a UPS

Safety: Protects users from electric shock by providing a low-resistance path for fault currents.
Prevents buildup of static electricity.
Equipment Protection:
Safeguards the UPS and connected devices from voltage surges, lightning strikes, or short circuits.
Reduces electromagnetic interference (EMI) and noise.
Stable Operation:
Ensures proper functioning of the UPS by maintaining a stable reference voltage.
Compliance:
Meets electrical safety standards and regulations (e.g., IEC, NEC, or local codes).

Earthing Connection in the UPS Back Panel

The earthing connection is typically located on the back panel of the UPS and is marked with the earth symbol (⏚) or labeled as “Ground”. Here’s how it works:

Earthing Terminal:
A dedicated screw terminal or connector for attaching the earth wire.
Usually made of brass or another conductive material for reliable conductivity.
Earth Wire:
A thick, insulated copper wire (usually green or green-yellow) connects the UPS to the building’s earthing system.
The wire should have low resistance to ensure effective grounding.
Connection to Building Earthing System:
The earth wire from the UPS is connected to the building’s main earthing point, such as a grounding rod or earthing busbar.

Steps to Connect Earthing in a UPS

Locate the Earthing Terminal:
Identify the earthing terminal on the UPS back panel (marked with ⏚ or “Ground”).
Prepare the Earth Wire:
Strip the insulation from the end of the earth wire to expose the copper conductor.
Connect the Earth Wire:
Attach the stripped end of the earth wire to the earthing terminal on the UPS.
Tighten the terminal screw securely to ensure a good connection.
Connect to Building Earthing System:
Run the other end of the earth wire to the building’s main earthing point.
Ensure the connection is secure and meets local electrical codes.
Verify the Connection:
Use a multimeter to check the resistance between the UPS earthing terminal and the building’s earthing point.
Ensure the resistance is within acceptable limits (typically less than 1 ohm).

Importance of Proper Earthing in a UPS

Prevents Electric Shock:
Fault currents are safely diverted to the ground, protecting users.
Reduces Fire Risk:
Prevents overheating and electrical fires caused by short circuits or surges.
Ensures Reliable Performance:
Proper grounding minimizes electrical noise and interference, ensuring stable UPS operation.
Compliance with Standards:
Proper earthing is required by electrical safety standards and regulations.

Common Issues with Earthing in UPS Systems

Loose Connections:
Loose or corroded earthing terminals can lead to poor grounding and safety hazards.
Regularly inspect and tighten connections.
Inadequate Earthing:
Using undersized earth wires or improper earthing points can compromise safety.
Ensure the earthing system meets local electrical codes.
No Earthing:
Operating a UPS without proper earthing is extremely dangerous and can lead to equipment damage or electric shock.

Solar Hybrid PCU MPPT 2.5KVA Mobile Application

Su-vastika

What is solar hybrid PCU having MPPT technology. https://suvastika.com/what-is-ai-based-solar-pcu-and-how-does-it-work/

Su-vastika 2.5KVA Solar Hybrid PCU with MPPT integrated with Bluetooth and Wi-Fi connectivity, designed for smart energy management and user-friendly control via a dedicated mobile app:

Key Features of the 2.5KVA Solar Hybrid PCU:

MPPT Solar Charging:
- High Efficiency: MPPT (Maximum Power Point Tracking) optimizes solar panel output, ensuring up to 30% more energy harvest compared to PWM controllers.
- Fast Charging: Faster charging of the batteries compared to the PWM Charge controller
- Wide Voltage Range: 2.5KVA comes in 24V and 22V model which can take up to 110V from the solar panels. It can support 1000 Watt solar panels which is ideal for Lithium battery 2.4KW capacity or Tubular Lead Acid battery 200Ah capacity 2 numbers.
  Solar PCU 2.5KVA solar panel connectivity. It can be connected with 540Watt panels as well.
Hybrid Power Management
- 4-in-1 Operation: Seamlessly blends power from:
  - - Solar priority: When the battery is charged to a certain level the load will be shifted to the Solar power even the grid is available so that the power bill can be saved during the solar sunshine.
    - Grid Bypass: The grid will be by passed when the battery is being charged through the solar power so that battery can charge faster and shift the power to solar energy. Bypass of Grid and charging is also done through the grid mode as solar is not available.
  - Battery and Solar Power for Backup: In case of power outages the systems work on battery or solar mode or both on battery and solar power depending upon the solar availability and battery power and load being run on the system.
  - When there is no Solar Power and the system is working on Mains (Grid) mode, then the Solar PCU will Bypass Mains (Grid) to flow directly to the Load and use Mains (Grid) to charge the battery.
    Overload Status
  - The Grid and Solar Sharing for Charging: Depends on the solar power availability and battery charged condition, If the battery is not charged properly and solar power is not sufficient to charge the battery then the Grid power will also start charging the battery along with the Solar Power so that battery remain in charged condition in case of power failure.When Mains and Solar are both available, the Solar PCU will use the following logic to determine which source to use for battery charging:
    - If the Mains(Grid) is available and the solar panels generate low current than the set charging current for the battery charging, then the Solar PCU will take the remaining current from the mains(grid) for charging the battery. It is called Grid sharing with Solar energy. For example; if the set charging current is 15A and solar panels generation is 10A then the remaining 5A current will take from Mains(grid).
    - If the mains(grid) is available and the solar panels are producing more current than the required current by the battery for charging, then the Solar PCU only use the solar panel’s current to charge the battery.
    Solar & Grid Charging Mains Mode
- UPS Functionality: Instant switch to battery mode during grid outages (<5ms) for uninterrupted power to critical loads. So all computers and TVs will not be switched off during the load shedding or switching from Solar to Grid mode or vice versa.

Smart App Integration (Bluetooth + Wi-Fi)
- Real-Time Monitoring: View live data on:
  - Solar generation, battery SOC (State of Charge).

  - Priority modes (Solar > Grid > Battery or custom),
  - Battery charging/discharging limits,
  - Load scheduling (e.g., run appliances during solar peak hours).
- Alerts & Diagnostics: Receive push notifications for:
  - Faults (overload, overheating, low battery),
  - Maintenance reminders (battery health, firmware updates).
- Historical Data Logging: Analyze daily/weekly/monthly energy reports to optimize usage.
Battery Management
