Frequently Asked Questions

A commercial battery storage system allows businesses to store excess electricity generated from renewable sources like solar panels or wind turbines, or from the grid during off-peak hours for later use, reducing energy costs and improving energy resilience with back up power function.
Adding an EnSmart commercial battery storage system to your business can be a smart investment, see why it’s worth it below:
· Lower Electricity Bills - Charge and store energy at low rates, use at high rates (load shifting).
· Reduce Peak Demand Charges - Avoid expensive spikes in energy consumption.
· Backup Power - Protect against outages and grid failures
· Maximise Solar Energy - Store and use excess solar energy instead of losing it
· Revenue Generation - Sell energy back to the grid (if applicable)
· Support Sustainability - Improve your company’s green credentials and reduce carbon footprint.The battery storage capacity (kWh) depends on your daily energy consumption (kWh) , peak load requirements, and the specific back up time goals (e.g., 1-hour vs. 2-hour backup).
First you need to analysis your daily energy consumption and determine critical loads and peak usage time.
A typical calculation is: Daily usage ( kWh) x Autonomy time / Depth of Discharge = Required Capacity ( kWh)
Factors like system efficiency (85-95%) , 90% DoD - The percentage of battery capacity used. Lithium-ion (80–90%) allows deeper discharge- .and future load growth should also be considered.
If your business has 50kWh daily consumption, you want 1 day of backup with a 90% DoD ( dept of discharge ) : 50kWh / 0.9 = 55.5 kWh
55.5kWh / 0.9 ( Efficiency) = 61.7 kWh total battery storage capacity needed.
EnSmart Power offers modular scalable systems like the Smart ESS-50K/100kWh Smart ESS 100K/215kWh which allow scalability and redundancy for your future growth.
For a 10 kWh daily usage, wanting 1 day of backup (autonomy), using a 90% (0.9) DoD lithium battery:
