What Size Solar Generator Do You Need to Run a Whole House?

Combined with AC charging from your wall, the charging capacity reaches 430 watts and the generator can recharge in as little as 1.2 hours. Our tests also showed that the Jackery Explorer 2000 (the power station part of this generator) uses about 86% of its stated capacity of 2,160 watt-hours. The Jackery SolarSaga 200 (the solar panel part of the generator) has an impressive 24.3% efficiency rating and a capacity of 200 watts. The solar generator can be charged with a maximum solar input of 1,400 watts, the highest mark of any that we tested. How many people living in your home will directly impact the system size you need. If you live alone, you can probably get away with a smaller solar generator, such as the EcoFlow DELTA Pro + 400W portable solar panel.

What’s the Installation Process for Solar Generators?

And when it comes to being prepared for an emergency, the general rule of thumb is that there is no such thing as having too much power. In a standalone solar kit, solar panels are usually permanently installed, although some can be stowed away and only used in case of an emergency. When determining the size of your solar array, it is important to consider your potential electrical load and spatial constraints, with a close eye on panel efficiency and warranty periods. If you’ve got the DIY gene or you're simply looking for your next home improvement project, it is also possible to install a solar kit as a whole house backup system. Here, the only real difference is that each of the solar generator’s components are purchased and installed separately, which can result in both a space-saving and cost-saving solution. A transfer switch is the safest way to connect a solar generator to a home for battery backup.

How we test solar generators

In that case, you’ll need to capture a substantial amount of solar power to keep your solar generator charged. The typical American household uses around 30 kilowatt-hours (kWh) of electricity per day, but using a ballpark figure when investing in a solar generator is never a good idea. Yes, a solar generator can power a whole house, but it depends on the size of the generator, the size of the house, and the household’s energy consumption. Generally speaking, a 2000-watt solar generator should be enough to cater to the needs of a typical house. The power stored in a solar generator’s battery is in direct current (DC), but most devices and appliances use alternating current (AC). If your solar generator doesn’t have a built-in inverter, you will need to purchase one separately, or you can purchase an inverter generator instead.

Frequently Asked Questions About Solar Generators

Solar generators are all-in-one solutions for harnessing and storing off-grid power. With its durable enclosure and ergonomic design, the GB2000 is our top pick for a solar generator you can take anywhere. Visit the SCE Battery Marketplace to explore your options with approved vendors. Once you review quotes and choose a vendor, they’ll help you through the application process. Coming in under $500, this RV-ready portable generator by Champion Power Equipment makes our list as the best budget generator of the bunch. It also features Quiet-Test Self-Test Mode, which runs at a lower RPM for five- or 12-minute tests.

Best Small Capacity

The Delta Pro gives you lots of options when it comes to powering appliances and other electronics. The advantage of an expandable system like the Delta Pro is that all the batteries act like one huge battery. Instead, the main Delta Pro unit draws power from all the batteries at the same time. It’s hard to choose the best 2000W home backup solar generator because there are so many of them in this range. Despite the relatively high output, the Delta Mini is mostly ideal for powering small and medium size appliances as well as recharging devices.

The biggest downside of using a solar generator for home backup is that you are limited in storage capacity. The inverter converts DC power from the solar panels to AC power that is compatible with your home electrical system. Portability is also important in solar tracking, where you move the solar generator and panels to maximize sun exposure. Square sine wave inverters are the cheapest and the least efficient. You are unlikely to find a solar generator with a square sine wave inverter. For years, we have said that solar generators cannot power an entire home.

ROCKPALS Portable Power Station

It also pays to ensure that your chosen solar panels can be linked together, or what's sometimes called daisy chained. For large homes in need of backup energy or permanent off-grid electricity, the Hysolis is a great standalone system to deliver massive amounts of solar power. Of course, if you are only worried about a few bad storms cutting out the power each year, then the Hysolis MPS might be a little bit of overkill to help keep the lights on. However, this generator is so powerful that it can keep nearly any home off of the grid for extended periods of time with continuous solar power. On the other hand, if you plan to limit your home's electricity consumption in the event of a grid failure, a medium-sized solar generator may only be necessary to power your essential items.

On the other hand, if you’ll be using your solar generator day in and day out, choose something with more life cycles, such as the Bluetti AC200P. I rarely need to use all six USB ports, but I always recommend generators with at least three AC outlets. If you have to drive all night and need your solar generator locked and loaded by tomorrow morning, that 12V car charger becomes your best friend. Its 1,000 watts of continuous AC power and the 1,002Wh battery were enough to power my electric grill for 50 minutes, my TV for 13 hours, and my mini-fridge for 17 hours.

The 9 Best Solar Generators of 2024

Propane is easier to store, cleaner and greener, and emits fewer fumes. If your primary goal is to have a solar-powered whole home backup power solution during blackouts, you may not need to consume as much electricity as you do when the grid is available. One of the main benefits of solar generators is that they use clean, renewable energy, which is better for the environment. It can also be better for your wallet, as solar generators avoid having to stock up on fuel to run your generator. Solar generators come with various outlets and charging ports to run several devices simultaneously. Common plugs include AC ports, USB-A and USB-C ports, and car cigarette lighters.

Even better, it features an automatic transfer switch and remote monitoring capability. The largest solar generator on the market is the Goal Zero Yeti 6000X, which has 6000W of capacity. Designed for outdoor events, cabins, and tiny houses, this large solar generator weighs over 100 lbs. Once you pay for the solar power generator and the panels to go with it, everything else is pretty much free. You have an unlimited supply of energy from dawn to dusk, no matter how far from the nearest outlet. There’s also the surge output, which is the extra-high wattage the generator can deliver over a few milliseconds to fire up machines that suck a lot of power at startup.

You can take it where you want to use it, and even go with it camping or in your RV. This makes it much more versatile compared to a wired solar backup system. Solar generators offer a clean backup power solution compared to gas generators. Add up their consumption and get a solar generator with enough watt-hours to last several hours or days. The other issue is the lack of a USB-C port, something that virtually all portable solar generators have.

If you'll need to back up a fridge or run a power tool, for example, make sure that your power station can meet the surge requirements, too. Alex is a co-founder of Shop Solar, a company that he established in 2018 to revolutionize the solar industry by simplifying the process and making it more simple and cost-effective. Between the two technologies sealed (or gel) lead-acid batteries are a massive improvement over traditional flooded technologies.

Like its bigger cousin, the Delta 2, the River Pro uses the same ultrafast charging technology, so you can charge it from the wall from 0 to 80% in an hour. With the Explorer 1000, I was able to charge my Macbook Pro eight times — on a single charge. The new lithium-iron technology gives you still unbelievable battery life of more than 3,500 charge cycles. This means you won’t have to think about getting one for the next 10 years, even with heavy use.
