Component Details

5.12kWh Lithium Battery:

LiFePO4 (lithium iron phosphate) for safety, longevity (~6,000 cycles), and high efficiency (90-95% round-trip)

Stores excess solar energy for use during nighttime, cloudy days, or outages

Supports ~1-2 hours of full 3kW load (80-90% depth of discharge) or longer for lighter loads

Compact design, typically with BMS (Battery Management System) for overcharge/over-discharge protection

3kW Hybrid Inverter:

Converts DC from panels/battery to 220-240V AC for household appliances

Features MPPT charge controller (~98% efficiency) for optimal solar energy harvesting

Hybrid functionality: prioritizes solar, switches to battery or grid as needed, supports grid-tie for excess power export (if permitted locally)

Includes protections (overload, short-circuit, low battery) and often app/Wi-Fi monitoring

4 x 550W All-Weather Solar Panels:

Total capacity: 2.2kW (4 x 550W)

High-efficiency monocrystalline panels, IP65+ rated for resistance to rain, snow, hail, and high winds

Designed for durability with tempered glass and corrosion-resistant frames

Mounted at 20-40° tilt, south-facing (Northern Hemisphere) for maximum sunlight capture

DC Breaker:

2-pole, ~63A rating, installed between panels and inverter

Isolates DC circuit during faults, overcurrent, or maintenance, preventing damage or fires

Ensures compliance with electrical standards (e.g., NEC or local codes)

Change Over Switch:

Manual or automatic, rated for ~16-32A to handle 3kW loads

Switches between inverter output (solar/battery) and grid power for uninterrupted supply

Ideal for outages, ensuring seamless transition to backup sources

AVS (Automatic Voltage Switcher):

Monitors AC voltage from inverter or grid, disconnecting loads if outside safe range (<180V or >260V)

Protects appliances from surges, brownouts, or unstable power with auto-reconnect delay (~3-5 minutes)

Installed on AC output side for system-wide protection
