Electricity powers nearly every moment of our day, from coffee machines in the morning and buzzing laptops to shop counters and fans that keep a summer evening comfortable. In India, that rhythm is increasingly protected as rooftop solar and smart backup options scale; as of July 31, 2025, the country has 119.02 GW of solar, including 19.88 GW of grid-connected rooftop, putting reliable, cleaner power within reach for homes and small businesses.
This is where a solar battery backup system paired with home energy storage changes the game. It lets you run your space on sunshine, store extra power for later, and enjoy an uninterrupted power supply with less dependence on the grid. In this blog, we show how MySine Tata Power does exactly that using a lithium iron phosphate battery to power homes and businesses while cutting down energy bills.
A solar battery backup system combines rooftop solar panels with an energy storage unit that captures excess solar electricity during the day and stores it for later use. This stored power can run your appliances at night or during outages, making your energy supply more reliable.
Energy Storage Systems help balance the ups and downs of renewable generation, deliver power during peak demand, and strengthen grid stability. Storage batteries can be part of net metering systems, allowing homes to first use their solar, then feed surplus to the grid, while keeping backup ready when it’s needed most.
Think of Tata Power MySine as the silent partner that keeps your day running smoothly. In a home, it might mean the fridge stays cold even during an afternoon outage so your groceries don’t spoil. In a retail store, the point-of-sale system never stops billing customers, even if the grid drops. At a petrol pump, the fuel dispenser and security cameras keep working without interruption.
MySine is a smart energy storage system built to handle Indian power realities - from short power cuts in cities to extended outages in rural or semi-urban areas. It draws electricity from your rooftop solar panels or the grid, stores it in a long-life lithium iron phosphate battery, and then delivers it instantly whenever the main supply dips.
The smart features of Mysine include:
- Uninterrupted power supply, even during outages
- Reduced grid dependence, with solar power
- Real-time monitoring of energy consumption via the Tata Power EZ HOME app
- Schedule and automate appliances and energy management
- Easy integration with EZ HOME devices and systems
Eligible under the PM Surya Ghar Yojana (PMSGY)* for residential systems (as per applicable State guidelines), households can now adopt Mysine with the added benefit of government subsidy support, making clean, reliable power even more affordable.
Here’s what happens when you have MySine solar power backup for home installed -
1. Solar generation first: During the day, rooftop panels generate power for your immediate needs.
2. Store the surplus: Any extra is stored in the LFP battery instead of being wasted.
3. Smart switching: If the grid goes down, MySine switches over in less than 10 milliseconds.
4. Nighttime savings: After sunset, you can run appliances on stored solar energy instead of drawing from the grid, reducing your electricity bill.
5. Mobile control: The companion app lets you monitor power flows and battery levels, and even control usage remotely.
Room to grow: If your needs change say you add an AC or expand your shop, you can increase storage capacity without replacing the whole system.
MySine is not just for lights and fans, it is designed to handle the kind of essential and high-usage loads that truly matter in everyday life.
1. For homes, that might mean keeping ceiling fans running through a summer night, with an uninterrupted power supply. This is not just a backup plan but a dependable daily resource.
While traditional lead-acid inverters have been a common choice for backup power, they come with compromises i.e. slower switchover times, higher maintenance, shorter lifespans, and less usable energy per cycle. MySine’s lithium iron phosphate battery is designed to solve these pain points with a more advanced approach.
1. Battery type: The heart of MySine is its LFP lithium iron phosphate battery, known for its safety, long cycle life, and high energy density. It avoids the toxic lead and acid found in older systems, making it safer for your family and the environment.
2. Instant switchover: MySine responds in less than 10 milliseconds when the grid drops, compared to 10–20 milliseconds in many traditional setups. That means your devices keep running without restarting or flickering.
3. Long life and reliability: With over 6,000 charge cycles and a lifespan of 10+ years, the home energy storage unit outlasts most lead-acid options by several years, reducing the frequency and cost of replacements.
4. Higher usable energy: MySine delivers around 85 - 90% usable energy per cycle, compared to just 50 - 70% in many lead-acid batteries. That means more of what you store actually gets used.
5. Faster charging: The solar battery backup system can be charged fully in 2 - 4 hours with efficiency of 97.6%, letting you quickly replenish storage after a cloudy spell or heavy usage.
6. Maintenance-free operation: No need for water top-ups or corrosion checks, MySine is truly set it up and don’t worry.
7. Eco-friendly and cost-effective: With safer materials, recyclable components, and up to 20% lower lifetime cost compared to traditional systems, MySine is both greener and more economical in the long run.

Lithium iron phosphate (LiFePO4/LFP) batteries outlast lead-acid batteries by a wide margin, deliver higher round-trip efficiency, and need minimal upkeep. You get more usable energy for home energy storage or backup power. Lead-acid needs regular watering and ventilation and wears out sooner. In short, choose LFP for dependable daily use.
Home energy storage lets you use rooftop solar power after sunset, keep essential appliances running during outages, and lower costs by shifting use to off-peak hours. A solar battery backup adds reliability and reduces dependence on the grid.
An off-grid solar battery backup system runs only on solar panels and batteries, without grid support. It works for remote areas but depends on battery capacity, sunny days, and upkeep. MySine Tata Power is a energy storage solution that combines solar power, grid supply, and a lithium iron phosphate battery for uninterrupted power supply. It offers near-instant switchover under 10 ms, faster charging, and about 6,000 cycles, giving higher usable energy, zero maintenance, and reliable solar power backup for home use during outages.
