A hybrid inverter is the brain of the system. It performs three main functions:
1. Converts DC from solar panels to AC for home use
2. Charges batteries with excess solar power
3. Manages power flow between solar, batteries, and grid
4. Provides seamless switching between power sources during grid failure

Lithium-ion batteries are best for most hybrid systems because:
• Higher efficiency (95-98%)
• Longer lifespan (8-10 years)
• Maintenance-free operation
• Faster charging
• Higher depth of discharge
Lead-acid batteries are economical but require maintenance and have shorter lifespan.

Battery lifespan depends on type and usage:
• Lithium-ion: 8-10 years or 4000-6000 cycles
• Lead-acid: 3-5 years or 1200-1800 cycles
• UTL solar batteries: 5-7 years or 1500-2000 cycles
Proper maintenance and avoiding deep discharges extend battery life.

Yes, hybrid systems are designed for expansion. You can:
1. Add more solar panels to increase generation
2. Add more batteries to increase backup capacity
3. Upgrade inverter capacity if needed
It's best to plan for future expansion during initial installation.

Net metering allows you to export excess solar power to the grid when your batteries are full. You get credits for this exported power, which are deducted from your electricity bill. Hybrid systems with net metering provide the maximum financial benefits by ensuring no solar energy goes to waste.

Hybrid system costs vary based on size and components:
• 3kW system: ₹2,10,000 - ₹2,50,000
• 5kW system: ₹3,20,000 - ₹3,80,000
• 10kW system: ₹5,80,000 - ₹6,50,000
Costs include solar panels, batteries, inverter, installation, and net metering setup.

Savings depend on your current electricity bill and system size:
• 3kW system: Save ₹3,000 - ₹4,000 per month
• 5kW system: Save ₹5,000 - ₹6,000 per month
• 10kW system: Save ₹10,000 - ₹12,000 per month
Most systems pay for themselves in 4-6 years through electricity bill savings.

Yes, under the PM Surya Ghar Muft Bijli Yojana, you can get:
• 30% subsidy on system cost up to 3kW
• 20% subsidy for additional capacity up to 10kW
• Additional benefits for systems with battery storage
We help with complete subsidy application and approval process.

Typical ROI periods:
• With subsidy: 3-4 years
• Without subsidy: 4-6 years
• Commercial systems: 2-3 years (due to higher electricity rates)
After ROI period, you get free electricity for the remaining system life (20+ years for panels).

Minimal maintenance costs:
• Annual AMC: ₹5,000 - ₹15,000 per year
• Battery replacement: Every 8-10 years for lithium
• Panel cleaning: ₹500 - ₹1,000 per cleaning
Maintenance costs are typically 5-10% of annual savings.

Recommended maintenance schedule:
• Daily: Visual inspection of indicators
• Monthly: Clean solar panels
• Quarterly: Professional inspection
• Annual: Comprehensive maintenance
• Battery-specific: As per manufacturer guidelines
