Description
The EcoFlow Solar Parallel Connection Cable is a branded EcoFlow cable with MC4 connectors for connecting solar panels in parallel. It combines two panels into one line, which then goes to the station through an MC4 to XT60i cable. If you want to buy EcoFlow Solar Parallel Connection Cable, below we explain how a parallel connection differs from a series one and when you need it.
Parallel or series
In a series connection the panels’ voltages add up while the current stays that of one panel. In a parallel connection it is the other way round: the voltage is that of one panel and the currents add up.
A parallel connection is needed when the total voltage of two panels in series would exceed the station’s solar input limit. For example, RIVER 2 takes 11-30 V, so two panels in series may go over the limit, while in parallel the voltage stays within a safe range.
According to EcoFlow, the cable is needed to connect two panels in parallel to RIVER series stations or four panels to DELTA stations.
How to connect
1. Connect the positive leads of the two panels to one Y-cable and the negative leads to the other. 2. Connect the Y-cable outputs to the EcoFlow MC4 to XT60i Solar Cable 2.5 m or its 3.5 m version. 3. Plug the XT60i into the station’s solar input.
Before connecting, check that the panels’ total current does not exceed the maximum current of the station’s solar input. For example, it is 15 A for DELTA 2 and 8 A for RIVER 2. If the current is higher, the station cannot use the surplus.

Which panels to combine
It is better to combine identical panels: the same model and the same power. Different panels do work in parallel, but the weaker one limits the efficiency of the pair. Panels with MC4 connectors in our catalogue include the EcoFlow 100W Flexible Solar Panel and the EcoFlow 2x100W Rigid Solar Panel.
Lightweight panels have a built-in XT60 connector rather than MC4, so this cable does not fit them without adapters.
What is in the box
The box holds the EcoFlow parallel connection cable. In EcoFlow’s photos it is a pair of Y-cables: one for the positive leads and one for the negative leads. The cable to the station and the panels themselves are sold separately. If you plan a system of two identical panels, we can put the whole set together at once: panels, Y-cables and an MC4 to XT60i cable of the right length.
FAQ
Can I connect more than two panels?
One Y-cable joins two lines. More panels need additional cables, and the total current must stay within the station’s input limits. Write to us and we will work out a layout for your station.
What is better for DELTA 2 Max or DELTA Pro?
These stations have a wide voltage range, so a series connection is often more convenient. Parallel makes sense when the panels stand in different places and are partly shaded.
How do I order?
You can buy EcoFlow Solar Parallel Connection Cable on its own or together with panels and a cable to the station.
