What is a Solar Portable Generator?
A solar portable generator or solar portable power station delivers power from a battery instead of fuel like a traditional generator. It’s a type of portable power station that has the ability to charge the battery through solar energy. Hence, you will need portable solar panels that you can connect to the solar generator.
Not all portable power station are necessarily capable of charging via solar. However, most of the portable power stations on the market today offer that option.Nevertheless, there are many differences between models in terms of solar charging performance. For instance the solar charging speed will be determined by the maximum Wattage input through solar. This maximum value depends from model to model. Also the amount of solar panels that can be applied and how large (in terms of watts) play an important role.
In this buyer guide we’ve selected the best performing solar portable power stations where the most important assessed criteria is solar charging performance. If you want to now what’s the best overall portable power station have a look at our Top 10 Portable Power Stations.

Top 3 Best Solar Portable Power Stations
- EcoFlow Delta Pro Portable Power Station (3600Wh)
- ZERO BREEZE ElecHive 2200 (2500Wh)
- EcoFlow Delta 2 Max Portable Power Station (2048Wh)
1. TOP PICK: EcoFlow Delta Pro Portable Power Station (3600Wh)
EcoFlow Delta Pro Review score: 4.7/5 stars
The EcoFlow Delta Pro received a high score based on our extensive tests and results. It showed excellent solar charging performance and has 1600W max solar input.
Best DealBattery Capacity and Power
The EcoFlow Delta Pro performed excellent in our tests. It has a large battery capacity of 3600Wh. This unit offers 5 AC outlets that give a maximum power of 3600W continuously and 7200W surge. There is an option that is called X-boost mode which allows you to even power an appliance of 4500W. However, this will be at a lower voltage so it’s not advisable to use this mode when your fine electronics are plugged in such as laptops etc.
By adding some additional batteries you can create a backup system of up to 25000Wh! These kinds of setups can also be eligible for a -30% tax credit (Clean Home Energy Credit).
Solar Performance
The EcoFlow Delta Pro has impressive solar charging capabilities. This makes it a great choice for off-grid and emergency power solutions. It supports a maximum solar input of 1600 watts. This high input capacity means you can achieve rapid recharging when paired with suitable solar setups. The solar recharge time depends on the panels used and sunlight conditions. For instance, with ideal conditions and the maximum 1,600W solar input, the Delta Pro can fully recharge in approximately 2.8 to 3.5 hours. This is a great solar performance. Though, charging time will vary depending on sunlight conditions and the number of panels used. You can use any solar panels as long as they use MC4 connectors and their combined voltage and current are within 11-150 volts.
Using this capacity, you can connect up to 8 portable solar panels, such as EcoFlow’s 400W panels. If you chain two Delta Pro units together with the EcoFlow Double Voltage Hub, the total solar input capacity doubles to 3200 watts, allowing for up to 16 panels in total​
Additionally, the Delta Pro is compatible with foldable and portable solar panels, providing flexibility for different outdoor or home backup needs. When combined with other charging methods, such as AC power or dual charging, the unit offers fast and reliable recharging to maintain readiness​.

How we test – Best Solar Portable Power Stations
We test portable power stations using a protocol that includes several important factors. These factors helped us evaluate the quality and performance of the power stations, and enable us to compare different models. Our product tests were either done in the “lab” or in the field to gain real life user experience. Here’s what we did:
- Battery Capacity: We fully charged the power station and then discharged it by running various appliances to determine how long it lasts. This enabled us to measure the battery capacity and how long the power station can last on a single charge.
- Power Output: During our moderate and heavy load tests we connected various appliances to the power station and measured the power output. This helped us determine how much power the station can deliver to devices.
- Charging Time: We connected the power station to various charging sources, such as wall outlets and solar panels, and measured the time it took to fully charge. This helped us determine the charging time of the power station.
- Weight and Portability: We carried the power station for a period and evaluated how easy it is to transport. This helped us determine the weight and portability of the power station.
By following this testing protocol we were able to evaluate and compare different portable power stations, and choose the best ones that suited our needs. For this “Solar Portable Power Stations” buyer guide we specifically looked for the best solar performance out of all the tested models.
