Who is this for?
Three Real-World Use Cases
Whether you face frequent power cuts, live in a remote area, or want to slash your peak-hour electricity bill — Solar + BESS has a solution for you.
Use Case 1
Residence with Unreliable Grid
Frequent power cuts? Never again.
The ProblemFrequent load shedding of 4–8 hrs/day. Generators are noisy, costly, and polluting. Inverters drain overnight.
- ✓Solar charges the battery during the day
- ✓Battery powers your home during cuts — silently
- ✓No generator fuel cost, zero noise
- ✓Automatic switchover in milliseconds
- ✓Lights, fans, fridge, TV — all covered
Use Case 2
Remote Homes & Commercial Sites
Where grid either doesn't reach or is highly unreliable.
The ProblemNo grid connection or erratic supply. High cost of extending grid lines. Diesel gensets running 24×7.
- ✓Fully off-grid or hybrid operation
- ✓Solar + battery covers day & night load
- ✓Eliminate ₹80–120/litre diesel cost
- ✓Scalable — add panels or batteries as needed
- ✓Ideal for resorts, farmhouses, clinics
Use Case 3
Commercial & Industrial — Peak Shifting
Store cheap solar energy. Use it instead of expensive grid power.
The ProblemHigh ToD peak-hour rates (6–10 PM). Excess solar generated at noon goes unused or exported at low rates.
- ✓Excess solar stored in battery during daytime
- ✓Battery discharges during costly evening peak hours
- ✓Avoid grid ToD surcharge of ₹2–4/unit
- ✓Maximise solar self-consumption to 90%+
- ✓Reduces MD (Maximum Demand) charges
How it works
The Hybrid Inverter — Your Smart Energy Brain
A hybrid inverter connects solar panels, battery, grid, and your home or business loads — and decides every second which energy source to use. Think of it as a very smart traffic controller for electricity.
Energy priority order — how the inverter decides
1
Powers your loads directly from panels
2
Used automatically when solar isn't enough
3
Expensive; the inverter minimises this
4
Earns net-metering credits (where allowed)
What happens at different times of the day
Morning (6 AM – 9 AM)
Solar starts generating. Inverter powers your loads from solar. Surplus goes to charge the battery. Grid not used.
Peak solar (10 AM – 3 PM)
Maximum generation. Loads fully powered by solar. Battery charges to 100%. Excess exported to grid, earning credits.
Evening (4 PM – 10 PM)
Solar reduces. Inverter switches to battery automatically — avoiding costly ToD peak-hour grid rates.
Grid cut / night
Battery continues powering essential loads. If battery is low and grid is available, it tops up automatically.
The result — maximum solar self-use, minimum grid dependence
A well-sized Solar + BESS system with a hybrid inverter achieves 85–95% solar self-consumption. For every ₹100 of electricity you'd normally pay the grid, you now pay under ₹10. The inverter handles all switching automatically — you don't touch anything.

Common questions
FAQs — Solar + Storage
Can I add battery storage to my existing solar system?
Yes, in most cases. If you have a regular solar inverter, it can be replaced or supplemented with a hybrid inverter, and batteries added. Our team will assess your existing system and recommend the most cost-effective upgrade path.
How many hours of backup will I get?
It depends on your battery size and your load. A 10 kWh battery can power a typical 3 BHK home (essential loads: lights, fans, TV, fridge) for 8–12 hours. We size the system based on your actual consumption data.
Is LFP battery safe? How is it different from normal inverter batteries?
LFP (Lithium Iron Phosphate) batteries are among the safest lithium chemistries — no thermal runaway risk, no toxic fumes. They last 4–5× longer than lead-acid batteries, need zero maintenance, and can be mounted indoors. They are a completely different technology from old tubular/lead-acid inverter batteries.
What happens to the battery on a cloudy/rainy day?
The battery will charge partially from whatever solar is available. For prolonged cloudy periods (3–4 days), the hybrid inverter automatically draws from the grid to top up the battery — so you are never without power. We account for local weather patterns when sizing your system.
Does BESS qualify for government subsidy?
The PM Surya Ghar Muft Bijli Yojana subsidy covers the solar panel component. Battery storage is currently not subsidised separately under most central schemes, though some state-level incentives exist. Our team will guide you through available subsidy options for your specific case.
