Grecell Portable Power Stations: Connect Any Solar Panel

Can I Connect Any Solar Panel To A Grecell Power station?

Grecell is a fast-growing popular power station/solar generator brand that makes and sells both batteries and solar panels.

While they do make their own panels, you don’t have to use them and can use third-party panels.

So the short answer to the question above is yes. Some panels are going to be easier to connect than others, but with the right adapters, cables, and accessories you can connect almost any solar panel.

In this guide, we’ll explore the different Grecell power station models, their input limits, and the best solar panels to pair with them.

If you have any questions, please leave a comment and I will help you as soon as possible.

Grecell Power Stations: Models and Specifications

In the table below, I have listed every power station currently being made by Grecell. If yours is missing, let me know by leaving a comment.

For a solar panel to be compatible with a power station, it must have a compatible voltage. That means the working voltage of the panel must be within the input limits of the power station. You can learn how to find the input limits of your power station here, or see the table below.

The solar panel voltage is a bit easier to find, and you can learn how to do it here.

The voltage limit should never be exceeded. If you already have a panel with a voltage too high for the specific model, you could use a DC buck converter like this (click to view on Amazon). It’s an adjustable power supply module that lets you reduce the voltage from 10-65V to 0-60V, and up to 12A. It requires some tinkering, and I don’t have any experience with them, so if this is something you would like to do I am going to have to refer you to the product manual.

The max input wattage can, however, be exceeded with most power stations. The charge controller will not send more than the amperage limit to the battery, but it’s able to regulate it. Note that you should always check with the manufacturer of your power station whether it is ok or not. You must usually exceed the amperage limit to reach the max input wattage. You can read more about that in this article.

Solar Panels – What You Need To Know

Now that we know the input limits of the Grecell power stations, it’s time to select a solar panel.

There are a couple of things you need to know before doing so, and these are true for all of the different models above.

1. Most power stations, and all Grecell models, have built-in solar charge controllers. That’s a big reason they’re often referred to as “solar generators”. The charge controller regulates the electricity produced by the panel and charges the battery at a safe speed. Because of this, you should not connect a panel that has an external charge controller. You want to make a direct connection between the panel and the input, with nothing in between except for maybe extension cables. If you already have a panel with a charge controller, see if it’s possible to bypass it.
2. To make the connection between the two, you must either choose a panel that comes with a connector that is compatible with your specific model, or use an adapter. In the table above I have specified whether the specific model uses an 8mm, Anderson or XT60 input connector. See what’s included with the panel you want to buy. A lot of the Grecell models have both the 8mm and the Anderson.
3. Since all Grecell power stations include MC4 to DC adapters (8mm, Anderson, or XT60), you actually don’t need to purchase any extra adapters. Unless you plan on connecting two or more panels in parallel, more info about that can be found down below.
4. If you have or plan to buy a panel that doesn’t use MC4 connectors, you’re going to need a different adapter. Please leave a comment and let me know what connector the panel has, and I will help you find the correct adapter.
5. I’ve mentioned it earlier, but the most important thing is that you find a panel with a compatible working voltage. Read this article to learn what to look for.

Solar Panel Recommendations

There are a lot of different type of panels, and I have written an article that talks about the pros and cons of each that you can read here.

Connect Two Or More Panels Together

To increase the charging speed, you can combine two or more panels. If this is something you would like to do, I suggest reading this article that go through the different ways to how that is done.
