- 48V, 100Ah: PKR 150,000–200,000
- 12V, 200Ah: PKR 100,000–140,000
- 24V, 200Ah: PKR 180,000–240,000
These prices are higher than traditional lead-acid batteries but are justified by their superior performance, longer lifespan, and compatibility with solar systems.
2. Compatibility with Solar Setups:
Lithium-ion batteries are highly compatible with solar setups due to their advanced technology and efficiency. Key points include:
- High Efficiency:
- Lithium-ion batteries have an efficiency of 95–98%, meaning more energy from solar panels is stored and utilized compared to lead-acid batteries (80–85% efficiency).
- Deep Discharge Capability:
- Lithium-ion batteries can be discharged up to 80–90% without damage, making them ideal for solar systems where energy storage and usage vary daily.
- Faster Charging:
- They charge 2–3 times faster than lead-acid batteries, ensuring quick energy storage during peak sunlight hours.
- Longer Lifespan:
- With 2,000–5,000 charge cycles, lithium-ion batteries outlast lead-acid batteries (300–500 cycles), making them a better long-term investment for solar setups.
- Compact and Lightweight:
- Their smaller size and lighter weight make them easier to install in solar systems, especially in residential settings.
- Temperature Tolerance:
- Lithium-ion batteries perform well in high temperatures, which is ideal for Pakistan’s climate and solar applications.
3. Advantages of Lithium-Ion Batteries for Solar Inverters:
- Energy Savings: Higher efficiency means less energy loss during charging and discharging.
- Low Maintenance: No need for regular water top-ups or cleaning.
- Scalability: Easily expandable for larger solar systems.
- Eco-Friendly: Fewer toxic materials and longer lifespan reduce environmental impact.
4. Popular Brands in Pakistan (2024):
