Best Solar Panels Compatible With Maxoak Bluetti EB150/EB240

Charge Your Maxoak Bluetti EB150/EB240 With Solar Panels

The Maxoak Bluetti EB150 and EB240 are two large power stations, also known as solar generators, that can be charged with solar panels.

In this post, I am going to help you find compatible solar panels that can charge the Bluetti batteries quickly, efficiently, and reliably. I rely on solar panels and lithium batteries myself as I travel fulltime in a travel trailer, so I know what it takes.

How To Connect Third-Party Solar Panels With MC4 Connectors

Maxoak includes an MC4 to 8mm adapter with the Bluetti EB150 and EB240, so they’re compatible with every third-party solar panel on the table above straight out of the box.

If you’re missing the adapter, this is the kind of adapter you need (click to view on Amazon).

What Makes A Solar Panel Compatible With The Maxoak Bluetti

The Charge Controller

The solar charge controller in the Bluetti EB150 is an MPPT charge controller with a 16-60V limit. This means that your solar panel(s) need to output between 16 and 60 volts. You can see the voltage of each panel above in the “Voc” section.

The EB240 has a slightly more powerful MPPT charge controller capable of input up to 68V.

How Much A Solar Panel Outputs

A 100W 12V panel outputs between 18-22 volts and I recommend using the higher number (Voc) when calculating how many solar panels you can safely combine in a series connection to connect to the Bluetti. The Voc voltage can usually be found in the specifications or manual of a solar panel.

So with a solar panel like the Renogy 100W, which has a 21.5V Voc, two panels in series would output 43V, while three would output 64.5V. Based on these numbers, you could connect two panels to the EB150, and three to the EB240.

Both the power stations have over-voltage protection built-in, so even if you would connect too many panels it won’t blow the charge controller but give you an error code.

The Amperage Limit

So we know now that both of them have voltage limits, but they also have amperage limits. Both can handle up to 10A, no matter how many volts (16-60/68V) your solar panels are outputting.

How To Reach The Maximum Input

There is a 500W max input on both power stations, which can be hard to reach by connecting panels in either series or parallel.

One solution is to use both a series and a parallel connection, a so-called series-parallel connection.

To do this, you need at least four panels. Let’s use the Renogy 100W in this example. Take two of the 100W panels, and connect them together with a MC4 Y Branch which connects the positive wires to one adapter, and the negatives to the second adapter separate from the positive.

Do the same thing with the two remaining 100W panels, and you should have two separate parallel pairs. Now take one of the pairs and use the MC4 male connector on one of the adapters to connect to the MC4 female connector on the second pair.

What you should be left with is an MC4 male connector on the second pair and an MC4 female connector on the first pair, this is a series-parallel connection.

Now you can connect the free connectors to the MC4 to DC adapter included with your Maxoak Bluetti.

This won’t reach 500W input, but it’s one way to get close to the maximum amp and voltage input.

Extension Cables

I use MC4 extension cables like the Windynation extension cables. If you’re doing a series-parallel connection, you might need a couple of the shorter versions to reach.

Frequently Asked Questions

Do I Need To Choose A Solar Panel With A Solar Charge Controller?

No, since the Maxoak Bluetti EB150 and EB240 have MPPT solar charge controllers built-in, you shouldn’t add another charge controller in-between.

How Can I Improve The Charging Efficiency/Speed?

One easy way to increase the charging efficiency and speed is to angle the panels so they’re facing the sun directly. This means that you have to move the solar panel throughout the day, but it’s worth it if you rely on the electricity the panel is producing.

It’s especially important to angle/tilt the panels during the winter months, or during the morning/evening hours when the sun is low on the horizon.

Another thing you should do is make sure there is no shade on any of your panels, not even a little bit.

How Much Solar Can I Connect?

Both power stations have a 500W maximum input, which can be hard to reach due to the volt and amp limits.

To reach the highest amount of input, I recommend doing a series-parallel connection with four panels. Wire two pairs in parallel, then do a series connection of the two pairs. This would get you close to both the voltage and amperage limit.

How Long Will It Take To Charge The EB150/EB240 With Solar Panels?

A 100W solar panel generates about 70W, so the EB150 would take about 22 hours, and the EB240 would take 35 hours. Buy two panels, and you’ll double the charging speed.

I would buy two Eco-Worthy 195W Monocrystalline solar panels and connect them in parallel with an MC4 Y Branch. Two of them would generate about 300W at most and charge the EB150 in about 5-6 hours, and the EB240 in 8-9 hours.
