Even though portable power stations, also known as solar generators can be charged with solar panels, most of them do not include solar panels. There are brands that sell kits that include compatible panels, but if you want to connect a third-party panel you must do some research before you buy one.

When connecting solar panels to a portable power station, understanding the input limits is crucial. Here’s a guide to help you figure out these limits and ensure safe and efficient use.

I will also provide some examples and how I found them.

What Are Input Limits?

Input limits refer to the maximum amount of voltage and current that the power station can safely handle. Exceeding these limits can damage the unit or reduce its efficiency.

The solar charge controller (which regulates the electricity generated by solar panels) in the power station decides what the limit is, and there isn’t anything you can do to change the limit with most power stations.

If the solar panel has a voltage too high for the charge controller in the power station and you’re somewhat technical, you can use a DC buck converter like this one by Drok (click to view on Amazon). This specific one supports input from panels with a working voltage between 10-65V and can reduce the voltage to 0-60V, and up to 12A.

Most portable power stations/solar generators have safety features that will simply prevent charging with a voltage that exceeds the limit without damaging anything, but it’s still a good idea to not push the limits.

The input current limits can usually be exceeded, and that’s often necessary to reach the max power input (watts). I do that with all of my power stations, but it’s unclear whether that voids the warranty or not.

Again, there is a difference between the input voltage limit and the input current limit. The input voltage limit should not be exceeded.

Based on my experience, if a power station accepts the voltage and current and starts charging, it’s fine. I haven’t had a single power station fail because of an exceeded current, but I know others have.

Steps to Determine Input Limits

Read the User Manual

The user manual is your primary resource. It includes detailed specifications about input voltage, current limits, and recommended panel configurations.

Look for sections specifically addressing solar input or charging limits.

What you’re looking for in the specifications is usually the numbers next to “DC Input”, “Solar Charging Input”, “Solar Input”, “MPPT Limits”, “Open Circuit Voltage Limit”, “Charging Input Voltage”, etc.

Check the Specifications Label:

Most portable power stations have a specifications label on the unit itself. This label usually lists the maximum input voltage and current.

Manufacturer’s Website:

Visit the manufacturer’s website to find the product page for your specific model. There you can find detailed specifications and often FAQs or support documents.

Customer Support:

If you’re unsure, contact customer support. They can provide precise information about the input limits and any compatible accessories or configurations.

Examples

Here are some examples, and how I found the information.

Jackery Explorer 1000

The Jackery Explorer 1000 has these specific input limits:

  • Input Voltage: 12-30V (from manual)
  • Input Current: Up to 7.5A (from manual)
  • Max Power Input: 200W (from product listing online)

These specifications mean you should ensure that the combined voltage of your solar panels does not exceed 30V and the current remains within 8A.

I found these numbers by looking at the product listing on both Amazon and Jackery’s website. It’s also in the manual, specifically by “DC Input” in the specifications.

The most important number here is the input voltage. It’s usually OK do exceed the input current limit even though the charge controller isn’t going to be able to use more than 8A, but you should never exceed the input voltage. The reason I say it’s OK to exceed the amperage limit is that it’s often necessary to achieve the max power input, since a panel isn’t 100% efficient.

EcoFlow Delta 2

The Delta 2 has these specific input limits:

  • Input Voltage: 11-60V
  • Input Current: Up to 15A
  • Max Power Input: 500W

These specifications mean you should ensure that the combined voltage of your solar panels does not exceed 60V.

I found these numbers by looking at the product listing on EcoFlow’s website. It’s also in the manual, specifically by “DC Input” in the specifications.

Anker Solix F2000

The Solix F2000 has these specific input limits:

  • Input Voltage: 11-60V
  • Max Power Input: 1000W

These specifications mean you should ensure that the combined voltage of your solar panels does not exceed 60V.

I found these numbers by looking at the product listing on Anker’s website.

Note that they do not list the input current limit, but tells us that the max input wattage is 1000W. As long as the panel(s) you connect doesn’t exceed the 60V limit, you’re good!

Connecting One Or More Solar Panels – Step By Step

  1. Check Panel Specifications:
    • Before connecting, check the voltage and current ratings of your solar panels.
    • Ensure that the total voltage when panels are connected in series or parallel does not exceed the power station’s input limits. If it does and you know what you’re doing, you can use a DC buck converter like this one by Drok (click to view on Amazon).
  2. Use Compatible Adapters:
    • Use the appropriate adapters or connectors recommended by the power station’s manufacturer to ensure safe and efficient connections.
  3. Monitor Charging:
    • Once connected, monitor the power station’s input display to ensure it’s receiving the correct voltage and current.
    • Avoid overcharging by using panels that match the power station’s specifications.

Why It Matters

Understanding and adhering to the input limits:

  • Prevents Damage: Protects the power station from overvoltage or overcurrent, which can lead to damage.
  • Optimizes Efficiency: Ensures the power station charges efficiently, providing reliable power when needed.
  • Safety: Maintains safe operation, preventing potential hazards like overheating or electrical faults.

  2. An early Christmas gift from my wife was a Jackery Explorer 1000 (model JE-1000D) and a 100 watt TWELSEAVAN solar panel (model TCSP-100w -M) .The cables, sold with the generator, seem to match the diagram sold with the panel. They are identified as MC4output at the panel and 4-in-1 at the generator. I have no input wattage into the generator with a fully charged and partially depleted battery. The panel connectors exit an unmarked black rectangular box. What connectors are required to correct this or what panel should we buy? Any help would be appreciated.

    • Hi,
      I think that’s the Explorer 1000 Pro model, so you need a DC7909 to DC8020 adapter. The Jackery should’ve included two of those, so try to connect one of them to the 8mm connector on the adapter provided by Twelseavan.
