100% Renewable Energy Storage & DC Distribution Bus to Micro-grid DC Operation Clusters

The target is zero fossil fuel used in our micro-grids.
They operate using HVDC for power distribution
utilizing large solar arrays/ wind generation at a central plant.

Design based on DC Power Distribution vs AC/DC

Higher Efficiency:
  • Reduced Power Losses: DC systems generally have lower transmission losses over long distances compared to AC systems. This is particularly beneficial in mining operations where power needs to be transmitted over extended distances
  • Stability: DC systems offer better voltage stability, which is crucial in maintaining consistent power supply to lighting and other equipment in harsh mining environments
Safety and Reliability:
  • Extra Low Voltage (ELV) Lighting: Using 48V DC for lighting is considered safer for workers, reducing the risk of electrical shocks and improving overall site safety
  • Robustness: DC systems are less susceptible to issues like reactive power and phase imbalance, which can be problematic in AC systems, especially in the rugged conditions of mining operations
Simplified Infrastructure:
  • Fewer Conductors: DC systems often require fewer conductors than AC systems, which can simplify the infrastructure and reduce installation costs
  • No Need for Phase Synchronization: DC systems eliminate the need for phase synchronization, simplifying the design and operation of the power distribution network

DC Reliability and Efficiency

High reliability of power to 99.999% can be achieved with a distributed DC micro-grid. 

  • A five-nines availability mandates a given service will be unavailable for no more than 5 minutes and 15 seconds a year.
  • Four-nines: 99.99% is unavailable 52 minutes and 36 seconds per year.
  • Three-nines: 99.9% allows 8 hours and 46 minutes of downtime per year.

When you want to eliminate your energy bill AND achieve Three Nines + availability, our Micro-grid is attractive.

WHAT WE DO

We are a one-stop shop providing 100kWh-1200kWh Energy Storge linked to 800V DC DC to 48V and 24V DC electricity services to anyone without a stable grid connection. We use a suite of DC DC Converters to mini-grids. We can provide 800V inter-connects between 48V sub-systems for efficient redundancy. Our Storage has integrated inverters at 415VAC from 100kW to 500kW off-grid. . Our software solution helps you understand your current energy needs better, optimize and model new technologies for your customized energy needs and operate and control your microgrid for an enlighted energy future. 

Micro-grid simulation and assessment software

Design based on Distribution of Renewable Energy at the DC level for maximum efficiency.

Renewable power is an uncontrolled source of power, but availability can be predicted. Energy storage solves the big issue of capturing excess renewable power, storing it, and releasing when required. For commercial operations of only 5/6 days/week, there may be surplus renewable solar power on weekends.

Data Analytics

Safiery’s dedicated team of engineers use data analytics to assess each customer’s energy requirements. Customers describe their lifestyle and the appliances they wish to use.  Safiery’s AI model uses this information to tailor a complete energy solution using a combination of different replenishment power sources of solar and vehicle alternators. Customers are then presented with a three-tier weather scenario and a forecast of time to go for lifestyle options.

Monitoring

However, it’s the monitoring of this customer after system installation that closes the loop on the theory and matches the real results to the model. None of this would be possible without accurate battery energy flow analysis and the CANbus Lithium provide this.
