Inverters and batteries are the central nervous system of any solar power system.
The Solar Inverter
The Brains of the Operation
The primary function of a solar inverter is to convert the Direct Current (DC) electricity generated by your solar panels into Alternating Current (AC) electricity, which is the type of power used by all your home appliances. Without an inverter, the energy from your panels would be unusable. But modern inverters do so much more—they manage power flow, optimize energy production, and provide crucial safety features.
The Solar Battery
The Energy Bank
A solar battery is a rechargeable energy storage unit. Its job is simple yet vital: to store the excess solar energy generated during the day. This stored energy becomes your personal power reserve, ready to be used at night, on cloudy days, or during a power outage. A battery system gives you true energy independence, reducing your reliance on the grid and eliminating the impact of blackouts on your home life.
Solar Inverters
1. On-Grid (Grid-Tied) Inverters
What they are: These are the most common inverters used for residential rooftop solar systems. They are designed to work in conjunction with the utility grid.
How they work: They convert DC power from your panels to AC power for your home. Any excess power is exported to the grid through a bi-directional meter, and you receive credits for it (net metering).
Key Function: Their primary role is to maximize the export of excess solar energy to the grid, helping you reduce your electricity bill.
Limitation: A key safety feature, known as Anti-Islanding Protection, automatically shuts down the system during a grid power outage. This prevents your solar system from feeding electricity back into the grid, which could endanger utility workers. This means they do not provide backup power during blackouts unless paired with a battery and a specific backup system.
2. Off-Grid Inverters
What they are: These inverters are used in standalone solar systems that are not connected to the utility grid.
How they work: They manage the power flow between your solar panels, your battery bank, and your home loads. All the energy generated by the panels is either consumed directly by your home or stored in the batteries.
Key Function: They are designed for complete energy self-sufficiency, making them ideal for remote homes, farms, or any location without a reliable grid connection.
Limitation: Since they are not connected to the grid, you have no external backup power source. You are entirely dependent on the energy stored in your batteries.
3. Hybrid Inverters: The Best of Both Worlds
What they are: A hybrid inverter combines the functionality of an on-grid and an off-grid inverter in a single unit.
How they work: This is the most intelligent and versatile type of inverter. It can seamlessly manage power from three sources: your solar panels, your battery bank, and the utility grid. It can decide in real-time whether to power your home directly from solar, charge your batteries with excess energy, or export power to the grid for credits.
Key Function: The biggest advantage of a hybrid inverter is its ability to provide backup power during a grid outage. When the grid goes down, it automatically disconnects from the utility and powers your home from the stored battery energy, all without any interruption.
Why we recommend them: For customers who want the best of both worlds—the savings of net metering and the security of a power backup—a hybrid inverter is the perfect solution.
Batteries for Your Home
The battery is the component that truly unlocks energy independence. The type of battery you choose impacts your system’s performance, cost, and lifespan. We primarily work with two main types of batteries:
1. Lead-Acid Batteries (Tubular)

Shorter Lifespan & Cycle Life: They typically have a lifespan of 5-7 years and a lower number of charge/discharge cycles compared to lithium.
Maintenance: They require regular maintenance, such as topping up the water levels in the cells.
2. Lithium-Ion Batteries (LiFePO4/LFP
What they are: This is the modern standard for solar energy storage. They are the same type of battery that powers electric vehicles and smartphones, but designed for stationary power storage.
Pros:
Cons:
High Efficiency: They boast a very high round-trip efficiency (90-95%), meaning more of your solar energy is available for use.
Longer Lifespan & Cycle Life: They have a much longer lifespan of 10-15 years and can handle thousands of charge/discharge cycles.
Zero Maintenance: They are sealed, maintenance-free units.
High Depth of Discharge (DoD): You can use up to 90-100% of their stored energy without damaging the battery.
Compact & Lightweight: Their high energy density means they can store more power in a smaller, lighter form factor, saving space.
Higher Upfront Cost: Their initial price is higher than lead-acid batteries, but their long life and superior performance can make them more cost-effective over time.
Temperature Sensitivity: Their performance can be slightly impacted by extreme temperatures, although modern Battery Management Systems (BMS) mitigate this.

1. Is a battery necessary for my solar system?
A battery is not always necessary, as it depends on your energy goals.
For On-Grid Systems: If your primary goal is to reduce your electricity bills through net metering and you have a reliable grid connection, a battery is optional. Your excess solar energy is sent to the grid for credits, and you draw power from the grid when needed.
For Off-Grid or Hybrid Systems: A battery is essential. It stores the solar energy you generate, allowing you to have a power supply at night, during cloudy days, or when the grid is down.
2. How long does a solar battery last, and what maintenance do they require?
The lifespan and maintenance requirements vary by battery type.
Lithium-Ion Batteries: These batteries are the modern standard and typically last 10-15 years or more. They are virtually maintenance-free, with a sealed design and an internal Battery Management System (BMS) that optimizes performance.
Lead-Acid Batteries: These are a more traditional and affordable option, with a typical lifespan of 5-7 years. They require regular maintenance, such as checking and topping up the water levels to ensure proper functioning.
3. What is the difference between an on-grid and a hybrid inverter?
The main difference lies in their functionality during a power outage.
On-Grid Inverter: This inverter is designed to work only when the grid is active. For safety reasons, it automatically shuts down during a power outage, meaning you won't have any power from your solar panels.
Hybrid Inverter: This is a more advanced inverter that can seamlessly switch between grid-tied and off-grid modes. When the grid goes down, it automatically disconnects from the utility and provides backup power to your home from the energy stored in your batteries. This ensures an uninterrupted power supply.
4. Are there government subsidies for solar batteries?
The central government's PM Surya Ghar: Muft Bijli Yojana offers substantial subsidies primarily for the installation of residential on-grid solar systems, with the subsidy capped at ₹78,000 for systems of 3kW and above. As of now, the scheme does not directly provide a separate subsidy for batteries. However, installing a hybrid system with a battery is a fantastic long-term investment that provides energy security and can be financed through our flexible loan and EMI options.
