Complete Energy Independence with Standalone Off-Grid Solar Systems

Produce, store, and consume your own clean electricity without any dependency on the public utility grid. Ideal for areas with frequent power cuts or no grid connectivity.

  • True 24/7 Power Runs day & night on battery backup
  • Total Grid Independence No utility connection needed at all
  • Lithium Batteries 10–15 year life with a smart BMS
  • Built for Bad Weather Oversized to run through cloudy days

An off-grid solar system — a true standalone setup — is built for remote and rural areas where the grid is absent or so unreliable that power is available for just 2–3 hours a day.

What Is an Off-Grid Solar System?

An off-grid solar system is a completely independent, standalone set-up that is not connected to the government or local utility grid.

It generates electricity using solar panels during daytime sunshine hours to run your home or business appliances directly. Any excess energy produced is stored in a dedicated high-efficiency battery bank, which keeps your property fully powered throughout the night or on overcast days.

1. Solar PV Modules

High-efficiency panels (Mono-PERC or Bifacial TOPCon) built to maximize output even in low light.

2. Off-Grid Solar Inverter

Built-in smart features to monitor thermal levels, loads, and prevent battery overheating.

3. Lithium Battery Storage

Provides maximum depth of discharge and rapid charging compared to traditional lead-acid batteries.

4. Solar Charge Controller

Protects batteries from overcharging and deep discharging.

5. Heavy-Duty Mounting Structure

Wind-tested structures designed to withstand harsh weather conditions.

How Does Off-Grid Solar Work?

From a photon hitting a panel to the light switching on in your home — here is the full journey.

1

Sunlight Absorption

Premium rooftop solar panels trap solar radiation and convert the photons into Direct Current (DC) electricity.

2

Charge Management

The generated DC electricity goes directly into a Solar Charge Controller, which intelligently regulates the voltage and current flowing to the system.

3

Battery Bank Charging

The charge controller feeds the necessary power into a high-capacity Lithium-ion (LFP) battery bank, storing the excess energy for later use.

4

DC to AC Conversion

An intelligent Off-Grid Solar Inverter converts the stored DC power into Alternating Current (AC) electricity, making it perfectly safe to run all standard household and industrial appliances.

Pros & Cons of Off-Grid Solar

Going off-grid buys you true energy independence — but it is worth weighing both sides before you commit.

The Advantages

  • 100% Energy Autonomy. Total independence from the government utility grid and power companies.
  • Zero Outages. Provides an uninterrupted power supply as long as your battery capacity handles the load requirements.
  • Remote Accessibility. The best and often only viable solution for rural areas, farmhouses, and places with minimal or no grid infrastructure.

The Trade-offs

  • Higher Upfront Cost. Batteries account for roughly 50–60% of the entire setup cost, making initial deployment more expensive.
  • Future Replacements. Even high-grade Lithium-ion batteries will require replacement after their operational cycle life is exhausted.
  • No Subsidy Benefits. Does not qualify for government net-metering solar subsidies.

Why We Use Hybrid Inverters

Grid-compatible inverters are simply the better fit for an off-grid power pack.

Lithium-optimisedDirect integration with the Battery Management System (BMS) extends battery life to 10–15 years or more.
97%+ efficiencyDual MPPT captures more solar across changing light and cuts conversion losses by 5–10%.
Rugged performanceHandles voltage surges and high-load appliances like water pumps where grid quality is unpredictable.
Future-proofDecide to connect to the grid or add battery storage (BESS) later and the same inverter supports it — no rewiring, no swap.

For reference, the off-grid inverter is about 10–15% of the total setup cost, the lithium-ion battery is roughly 50–60%, and the remainder covers all the other solar components.

Off-Grid Solar System Price in India in 2026

Price depends on the system capacity, the type of panels, the type of inverter, the battery capacity and the battery chemistry (lithium-ion vs lead-acid).

System Size (with lithium battery)Indicative Price in 2026*
1 kW off-grid system + 1 kWh lithium battery₹95,000
2 kW off-grid system + 3 kWh lithium battery₹1,80,000
3 kW off-grid system + 5 kWh lithium battery₹2,65,000
5 kW off-grid system + 7.5 kWh lithium battery₹4,30,000
7.5 kW off-grid system + 10 kWh lithium battery₹6,50,000
10 kW off-grid system + 15 kWh lithium battery₹8,50,000

What about an off-grid solar subsidy?

To set the record straight: the Indian government does not offer a subsidy on off-grid solar systems with battery storage. The PM Surya Ghar: Muft Bijli Yojana subsidy (up to ₹78,000 central) applies only to grid-connected systems. To claim it, you would need to install an on-grid or hybrid system instead.

How to Size a Battery for Off-Grid Products

The battery is the biggest line item in any off-grid system, and four design inputs drive its size.

1 day
Autonomy

The bank is sized to cover your full 24-hour load, with enough reserve to carry you until the sun returns the next morning.

80%
Depth of Discharge (DoD)

Lithium batteries can safely use about 80% of their rated capacity, so the bank is oversized to protect long-term battery health.

85%
Round-Trip Efficiency (RTE)

Some energy is lost charging and discharging. Sizing accounts for the ~15% round-trip loss so real-world output meets your need.

Split
Day – Night Load Split

Loads used after dark must come entirely from storage, so a higher night-time share means a larger battery bank.

This is why the battery in an off-grid solar product is typically 2 to 4 times larger than the battery in a hybrid solar power pack of the same system size.

Off-Grid vs On-Grid Solar

The main difference between off-grid and on-grid systems comes down to batteries and the grid connection.

FeatureOff-Grid Solar SystemOn-Grid Solar System

Conclusion

An off-grid solar system is the right call when your grid is unreliable or simply not there. It buys complete energy independence with battery backup, but it costs more upfront and earns no subsidy, so battery sizing and component quality matter enormously.

That is exactly where Clans Machina comes in. We design, supply, install and monitor your off-grid system end to end — sizing the battery correctly the first time and backing it with a 25-year performance warranty. Book a free consultation now for an exact, itemised quote.

Frequently Asked Questions

In 2026, an off-grid system with a lithium battery starts at around ₹95,000 for 1 kW and rises with capacity — roughly ₹2,65,000 for 3 kW and ₹8,50,000 for 10 kW. The final price depends on your battery sizing, panel and inverter type, and site conditions.

No. The PM Surya Ghar: Muft Bijli Yojana subsidy applies only to grid-connected (on-grid) systems. Off-grid systems with battery storage are not eligible for any government subsidy.

It depends on your daily energy use and how much autonomy you want. The bank is sized to cover a full 24-hour load with reserve — which is why an off-grid battery is typically 2 to 4 times larger than a hybrid system of the same size.

Yes — provided the system and battery bank are sized for it. Air conditioners are heavy loads, so we factor in their running hours when designing the panels, inverter and battery capacity.

If your grid is reliable, on-grid is cheaper, qualifies for subsidy and pays back faster. If your grid is absent or very unreliable, off-grid is the better choice because it delivers true 24/7 independent power.
