How to Choose the Right Solar Generator for Your Home

What should I look for in a solar generator?

When shopping for a solar generator, start by considering your specific power needs. Are you preparing for short-term power outages, powering a small off-grid cabin, or keeping essential devices charged during emergencies?

Key factors to evaluate:

• Battery capacity (Wh): The total amount of energy stored, this determines how long your solar generator can power your devices.
• Inverter size (W): Determines how many watts can be used at once
• Port options: AC outlets, DC, USB-A, USB-C, Anderson, etc.
• Weight and portability: Most portable solar generators range from 10 to over 50 lbs, depending on battery capacity and power output.
• Solar input compatibility: Ensure your solar backup generator accepts the input wattage you need
• Recharge time

You want the right balance between power output, portability, and price. For most home backup power needs, a portable solar generator between 1000 and 2000Wh provides the ideal mix of capacity and convenience.

How Much Wattage Do I Need from a Portable Solar Power Station?

Calculate the total wattage of the devices you plan to run. Here’s a simple breakdown:

A 1000Wh solar generator can run:

• A fridge (~100W) for 8-10 hours
• A laptop (~60W) for 15 hours
• Multiple lights for days

If you want to power multiple devices simultaneously, make sure your solar power station's inverter can handle the combined load.

Do I need solar panels included?

Not all solar generators come with panels, and not all panels are equal.

Look for:

• Panel wattage: Higher wattage = faster recharge
• Portability: Foldable and lightweight panels for easy transport
• Compatibility: Ensure voltage/amperage aligns with your generator

Solar Panels are essential if you plan to be off-grid or recharge during long-term power outages. For home backup, wall-charging ahead of time may be enough.

Portable vs. Stationary Solar Backup Generators: Which Is Right for You?

Portable Solar Generators:

• Ideal for: RVs, camping, short power outages, versatile home backup
• Weight: Lightweight (10-30 lbs)
• Capacity: 500Wh-2000Wh typical
• Pros: Easy to move, store, and deploy. Best solar generators for beginners.
• Cons: Limited capacity for whole-home backup

Stationary Units:

• Ideal for: Full-home or long-term backup, permanent off-grid installations
• Heavier: Often over 50 lbs
• Capacity: 2000Wh-10,000Wh+
• Pros: High capacity, solar panel expandability, can power entire home
• Cons: More expensive, less portable, complex installation

If you're looking for daily utility and peace of mind during emergencies, a mid-size portable solar generator with 1000-2000Wh is a solid choice.
