Frequently asked questions about GK's Solar Rooftop
BESS Basics & Understanding
Is kW the same as kWh?
No. kW is the rate of power; kWh is stored or delivered energy. Both are required to describe a BESS.
How long will a battery run my load?
Approximate duration equals usable energy divided by load, but actual duration also depends on conversion losses, auxiliary consumption, temperature, state-of-charge reserve and battery age.
What is an augmentation?
Additional battery capacity installed during project life to compensate for degradation and maintain the contracted usable energy or duration.
Backup, Grid & Solar Integration
Can BESS replace a diesel generator?
It can reduce or, in suitable cases, replace generator operation, but autonomy, recharge source, long outages, motor starting, black-start capability, and regulatory requirements must be engineered.
Can the battery charge from rooftop solar?
Yes, with a compatible AC-coupled or DC-coupled design. The preferred architecture depends on the existing solar plant, backup requirement, metering and interconnection rules.
Can the battery charge from rooftop solar?
What happens when the grid fails?
Performance, Life & Safety
What is the life of a BESS?
Life is not a fixed number. It depends on chemistry, calendar age, cycles, depth of discharge, power rate, temperature, state of charge, and warranty conditions. Evaluate both years and guaranteed energy throughput.
Is LFP completely fireproof?
No battery system should be described as fireproof. LFP is generally regarded as having stronger thermal stability than some other lithium-ion chemistries, but it still requires engineered prevention, detection, isolation, and emergency response.
