What is a BESS?
A BESS is a set of batteries, a power conversion system (inverter) and a battery management system that controls charging, discharging and safety. It can charge from the grid, from solar, or both.
Where battery storage helps
- ·Backup power: keep critical loads running through outages without noisy diesel generators.
- ·Peak demand management: discharge during peak periods to reduce the maximum demand that appears on an HT bill.
- ·Solar self-consumption: store midday solar for use in the evening or night shift.
- ·Power quality: smooth out voltage dips and short interruptions for sensitive equipment.
Capacity: kW and kWh are different
Power (kW) says how fast the battery can deliver energy, and capacity (kWh) says how much it can store. A good design matches both to your load profile. We study your demand data before suggesting a size.
What to check before you buy
- ·Battery chemistry, cycle life and warranty, including what capacity is guaranteed after how many years.
- ·Battery management system and safety features such as thermal monitoring and fire protection.
- ·Space, ventilation and installation requirements at your site.
- ·How the system will be controlled, and whether it integrates with your existing solar and panels.
- ·Whether the savings from peak shaving or backup justify the investment for your tariff and load.
When battery storage may not be worth it
If your outages are rare, your load is steady in daytime and your solar is fully used, a battery may add cost without much benefit. In that case, a well-designed solar plant alone is often the better investment. We will tell you honestly which case you are in.
