Choosing the Best Solar Generator for Your Home

1. Battery Capacity (Wh or kWh)

Higher capacity = longer runtime.

• Emergency essentials: 1,000–1,500Wh
• Daily backup: 2,000–3,000Wh
• Whole-home lite backup: 3,000–6,000Wh

2. Inverter Output (W)

Determines how many appliances can run at once:

• 1,200–2,400W → basic essentials
• 3,000W+ → refrigerators + power tools + medical devices

3. Solar Input Capacity

Faster solar input = faster recharge.
Look for:

• 400W–800W input for small systems
• 1000W–2400W input for larger home backup units

4. Battery Chemistry

LiFePO4 is ideal because it offers:

• 3–4× longer lifespan
• Better safety
• Higher efficiency

5. Expandability

The best systems allow:

• Add-on batteries
• Additional solar panels
• 240V split-phase pairing for larger home loads

6. Port Selection

Look for:

• Multiple AC outlets
• USB-C PD ports
• DC carport
• RV/TT-30 ports
