Looking to power your home sustainably? Discover the best solar generators for your house in our latest blog. Imagine harnessing the sun's energy to keep your lights on during an outage, charge your devices, or even power essential appliances. Solar generators are not only eco-friendly but also a reliable backup during emergencies. In this comprehensive guide, we compare top models, highlighting their features, capacities, and benefits. Whether you're a homeowner looking to reduce your carbon footprint or simply seeking a dependable power source, find the perfect solar generator for your needs right here.
Why solar generators are the best power source for home?
Solar generators can be used indoors because they produce no harmful gasses.
Most solar generators can be charged with an AC wall socket, Car DC port, other batteries, solar panels, and Gas generators.
Solar generators can be used while charging.
You can use both portable and conventional solar panels with solar generators. However portable solar panels are not rainproof (only splashproof) and cannot withstand heavy wind. Moreover, conventional panels require structure, which increases the total cost of the plant.
Most solar generators have dual charging options. You can charge them with solar panels + AC wall socket/Gas generator.
You can't take solar generators on flight Learn more.
You can get up to 30% federal Tax credit on the purchase of a solar generator. >>Learn more about the benefits of Investing in Solar generators for House use.

Mango Power E is our second top choice of solar generator for Home backup during longer power outages, due to its Lithium-ion CATL-LFP battery, which has a 5,000-6,000-charge cycle. Whereas its close competitors, Bluetti & EcoFlow have Lithium Iron Phosphate batteries with a 2,500-3,500-charge cycle. That means, where both Bluetti & EcoFLOW need a battery change in 8 to 10 years, Mongo Power E will require a battery change in 15-18 years.
It has a battery capacity of 3,530kWh, which can be doubled by using its expendable 3,530kWh battery. However, this additional battery needs to be purchased separately.
You can pair two expanded units of Mango Power E to achieve a maximum of 14kWh battery backup with 6kW inverter power at 240V. This is a full-fledged home backup bundle that you can connect to your home circuit and is a cool alternative to Bluetti EP500 and EcoFlow Delta Pro.
The Mango Power E Power Station also has a BACKUP mode, which will automatically switch from grid to battery power when there is a power outage.
It has an AC charging capacity of 3,000 Watts, which is a pretty decent capacity for this range. It can be charged via solar panels. Moreover, the 2,000-watt solar input capacity is less than Bluetti's AC500 and AC300. However, 2,000 watts of solar panels are enough to charge an 8,000 Wh battery in a single day.
It has a maximum output power of 3,000 watts. It has a total 16 numbers of ports, which includes 4 numbers of 20A AC ports and One 30 Amp AC RV port.
Here is something cool, its expendable battery also has 3 numbers of DC outputs. Which also, includes a 12V, 10A Car DC port. Its expendable battery can be charged via a 12V Car DC port, without the need of its solar generator unit.

How do you choose the best solar generator for your house?
To choose the best solar generator for a house, we considered different factors like battery capacity, expandability of battery capacity, MPPT rating, Inverter rating, and Converter rating. Some of the factors are explained below.
Battery Type: Lithium batteries are used in solar generators to make them light in weight. Furthermore, most solar generators have two types of lithium batteries, that is LPF and NMC. NCM is one of the newest members of the lithium battery family. However, studies show that its performance is lower than LPF batteries.
However, Monago Power E is the only solar generator, which has a CATL LFP battery. CATL LFP batteries have 1.7 times more charge cycles than LPF batteries.
Also, LPF batteries have a 3.5 times higher charge cycle than NCM batteries. Here, one charge cycle is equal to the charging of the battery followed by 80% depth of discharge. Furthermore, an LPF battery has a charge cycle of 3500, NCM batteries have a charge cycle of 800 and CATL LFP batteries have a 6,000 charge cycle.
Battery Expandability: The power of a house changes as the family members increase as well as new appliances are added to the daily routine. Hence, the backup capacity of a fixed-capacity solar generator won't be that useful.
However, the backup capacity of a solar generator with expandable battery capacity can be adjusted as per the house load requirement.
Inverter Rating: The inverter capacity of a solar generator limits the number of appliances it can run simultaneously. As per the EIA report, the average load demand of houses in the USA is about 2kW.
Hence, for powering the entire house any solar generator with an inverter capacity lower than 2kW, won't fit for its purpose.
AC Input [converter] Rating: To reduce the price of solar generators and keep the profit high. Some solar generator manufacturers reduce the electronic of AC Converter, Hence, their solar generators take more time to get charged. A fast-charged solar generator has more advantages than a slow-charged solar generator.
Solar generators with higher AC converter ratings get charged faster and will get ready for power outages faster.
Numbers of ports: To run the whole house on the solar generator, you will require sufficient numbers of output ports with varieties so that all the required numbers of appliances can be run on it. Most solar generators with a capacity of 2000W and above have 12 to 18 numbers output ports.
We recommend at least 10 numbers output ports so that a maximum number of houses can be run simultaneously. Hence, any solar generator with output ports less than 10 is out of the list.
PV Input [MPPT] Rating: A higher PV input rating means a longer backup time. FYI, 1 kW of solar panel can charge a 2,000 - 4,000 kWh battery in a day. Hence, we prefer solar generators with higher PV input ratings over lower PV input ratings.
The PV input capacity of a high-range solar generator varies from 12,00 Watts to 24,00 Watts.
