Appliances You Can Run With Each Generator (Wattage Chart)

Solar generators are perfect for powering essentials during outages or when living off-grid. Even mid-sized models can keep food cold, lights on, and medical gear running. Here’s a quick look at how long common appliances can run on two different generator sizes:

Appliance	Avg. Wattage	Runtime (1500Wh)	Runtime (3000Wh)
Full-Size Fridge	150W	10 hrs	20 hrs
WiFi Router + Lights	50W	30 hrs	60 hrs
CPAP Machine	40W	35 hrs	70 hrs

This chart shows why capacity and efficiency matter. Even a 1500Wh model can keep key appliances going overnight, while a 3000Wh system can stretch that runtime out to multiple days—especially if paired with solar panels for daytime charging.

How to Choose the Best Solar Generator for Home Backup

Picking the right solar generator isn’t just about choosing the one with the biggest battery. It’s about matching the system to your specific needs—your appliances, your usage habits, and how long you want to stay powered during an outage.

To help with that, here are the most important things to think about when choosing a solar generator for your home:

Battery Capacity

The battery capacity, measured in watt-hours (Wh), tells you how much energy the generator can store. The higher the number, the longer it can power your devices without needing a recharge.

For example, a 2000Wh battery can run a 100W light and a 150W fridge for about 6–8 hours combined. If you want overnight or multi-day coverage for appliances like a fridge, CPAP machine, or modem, look for a generator with at least 2,000Wh of capacity—or one that allows expansion later.

Output Power

Output power, measured in watts (W), determines what devices you can run at the same time. You’ll want to check both the continuous (rated) output and surge (peak) output. The rated output is the safe limit you can draw constantly. The surge is what it can handle for a few seconds, which is important for devices with startup spikes like refrigerators or well pumps.

If your generator puts out 3000W, it can run a space heater, fridge, and a few lights at the same time. If your needs include AC units or cooking appliances, you’ll want at least 3000–5000W output—and possibly 240V capability.

Charging Speed

Recharging speed becomes critical during extended outages or off-grid use. A fast solar input or AC input means you’re not left waiting while your generator charges.

Some models support dual charging—solar and AC at once—which can cut charging time in half. Others accept high-wattage solar panels (like 1000W–2400W), allowing you to recharge a 3000Wh battery in just 1.5–3 hours with good sunlight.

Portability and Weight

If you plan to keep the generator in your garage or a permanent backup location, weight may not be a huge concern. But if you’re using it for RV trips or want to move it around easily, weight becomes a major factor.

Generators with built-in wheels and handles are easier to manage, even if they weigh 100 lbs or more. For home users who need occasional transport—like during severe weather warnings—portability matters more than you think.

Smart Features and Safety Protections

Modern generators often come with mobile apps that let you check battery status, input/output levels, and even prioritize energy usage. Look for units with LiFePO4 (LFP) batteries for longer life and higher safety.

Features like UPS (uninterruptible power supply), silent operation, short-circuit protection, and fire-resistant casings are especially valuable for indoor use.

How to Size a Solar Generator for Your Home

Sizing your solar generator starts by understanding how much power you use—and for how long you’ll need it. Your goal isn’t to power everything at once but to cover the essentials during an outage.

Start by listing the critical appliances you need to run, then estimate how many hours per day you’ll use each. Multiply that by the wattage to get your total watt-hours. Compare that number to the generator’s capacity.

Here’s a simple breakdown to help:

• Refrigerator (150W, 10 hrs/day) = 1500Wh
• WiFi + Lights (50W, 12 hrs/day) = 600Wh
• CPAP Machine (40W, 8 hrs/day) = 320Wh
• Laptop (60W, 5 hrs/day) = 300Wh

Total Estimated Daily Usage: ~2720Wh

If you want to run these devices for a full day, a 3000Wh battery would be a good match. For longer outages or cloudy days, consider models with expandable battery banks or faster solar charging. To better understand how much wattage different household items consume, check out our guide on what a 12000-watt generator can run.

Solar Panel Pairing: What to Look For?

Your solar generator is only as good as its recharge system. That’s where solar panels come in—and not all are created equal. The panel’s efficiency, wattage, and voltage need to match the generator’s input specs to ensure fast, reliable charging.

Some generators support up to 2400W of solar input, while others max out at 400–600W. Make sure your panel setup meets (or nearly meets) the input capacity to avoid slow recharges during emergencies.

Here are the key things to consider:

• Panel Wattage: Higher wattage means faster charging. For example, two 200W panels will recharge faster than a single 100W panel.
• Efficiency Rating: Look for monocrystalline panels with 20–23% conversion efficiency.
• Connector Type: Match the connector (MC4, XT60, Anderson, etc.) to your generator.
• Portability: Foldable or suitcase-style panels are easier to store and move.
• Weather Resistance: IP65 or IP68 rated panels perform better in rain, dust, or wind.

Pairing the right panel with your generator can make the difference between a system that keeps up and one that leaves you in the dark.

Are Solar Generators Safe for Indoor Use?

Yes, solar generators are safe to use indoors—unlike gas-powered units, they don’t produce fumes or require combustion. This makes them ideal for bedrooms, apartments, RV interiors, and even offices during outages.

Because they run on lithium batteries, solar generators operate silently and with minimal heat output. Most modern models are also equipped with built-in safety features such as overcharge protection, short-circuit prevention, and UL certifications for indoor use.

Still, it’s important to ensure proper ventilation when charging and to avoid placing units near heat sources or flammable materials. If you’re using a model with high output capacity, give it space to cool naturally—especially during prolonged use.

Solar Generator vs Gas Generator: Which Is Better for Home Backup?

Solar generators are cleaner, safer, and quieter than gas generators, making them a better fit for most home backup needs—especially indoors. While gas units may provide higher power output for some tools or entire homes, solar generators offer unmatched convenience for day-to-day use, medical devices, and long-term savings.

Here’s how they compare:

Feature	Solar Generator	Gas Generator
Fuel Cost	$0	$2–$4/day
Indoor Use	Yes	No
Maintenance	Low	High
Runtime (w/sun)	Unlimited	Limited
Power Output	Medium	High

Gas generators still have a place in extreme backup scenarios, but for most households, solar covers the essentials without the fumes or fuss. And if you do need something with more output, especially for larger homes, it’s worth looking into the whole house generators that offer robust power and automatic operation.

Only high-capacity systems like the BLUETTI EP500Pro or EcoFlow Delta Pro can run whole-home loads—especially when paired with transfer switches or 240V output. Most solar generators are ideal for running essentials, not everything at once.

How long does a solar generator last?

Most quality solar generators use LiFePO4 batteries rated for 3,000–6,000 charge cycles, meaning they can last 7–10 years or more with regular use.

Do I need solar panels with my solar generator?

While not required for initial use (you can charge via wall or car), solar panels are essential if you want off-grid capability or multi-day performance during outages.

Can I leave a solar generator plugged in all the time?

Yes, many models are designed for standby use and include UPS (uninterruptible power supply) features. Still, it’s good practice to check battery health every 1–2 months.
