Ecoflow delta 1300 with MC4 to SAE adapter?

My 1 month old EF delta battery accepts dc 12v from car. But not solar Via mc4 to sae adapter (from Igreely) with either renology panels (2x100w) or a 130W blanket.

EF support says should only use our panels (despite advertising “universal solar compatibility“).

any suggestions welcome as to what I may be missing?. Newbie here.

Unfortunately, I don't feel like you've supplied the necessary information.

From:


Page 9:

"Users can buy universal solar panels of MC4 connection standard on their own to power EF DELTA, as long as the voltage and current (10-65V DC, 10A max) comply with the specifications of EF DELTA, the panels will be able to recharge EF DELTA through the MC4 to XT60 conversion cable. However, EcoFlow will not be responsible for providing free repair services for any damage to the product caused by the quality issue or improper operation of the third party solar panels, even during the warranty period. "

The "what's in the box" section of the website indicates you should have a:

"MC4 to XT60 Solar Panel Charging Cable"

That should allow you to connect an MC4 panel to your unit with the supplied cable. Add parallel adapters as needed.

Yes the box has the MC4 to XT60 connector, however if your solar panels do not use the MC4 connection, then an adapter is necessary. What I'm reading seems to be unless your solar panel has this specific connection, you're out of luck? Hardly "universal" as it seems anderson or SAE are far more common.

Yes one could splice on an MC4 connection, but how is that different than buying an adapter to make connection. I just don't understand what is happening with the current through an adapter that is preventing the charge.

It is my understanding that MC4 connectors are prolific and the most common type of connector for STANDARD panels. Everywhere I look, I see panels with MC4 connectors. Given that every panel intended for mounting has MC4 connectors and that mounted panels comprise the vast majority of the panels produced in the world, I would argue that MC4 connectors are vastly more common and "universal".

Even these flexible solar panels come with MC4 connectors:


For portable panels or market niche application, they may be less common.

Can you explain what you mean by this:

"I just don't understand what is happening with the current through an adapter that is preventing the charge."

I'm not saying it wouldn't. They probably say that (if they do) because if you create or purchase an adapter, there's a chance polarity gets reversed, and something pops.

If you find an adapter that works for your situation, I would say it's fine if you triple check that the polarity is correct.

Ok I have the adapter: but it does not work, with or without the polarity reverse dongle it comes with. So it sounds like whatever I plugged in first was bad and killed the MPPT in the DELTA. awesome. I was unaware that polarity issue could brick the device, and since I'm in the field, do not have a voltmeter with me to check.

DIY learning often comes with costs associated with the learning part.

It sounds like they may warranty the unit however based on the thread you posted looks to be a bout a 2 month process.

For others that find this thread, Will does make a note to check his polarity via a meter in his videos (he shows doing it) before connecting batteries and pannels. You should always have a meter to do the same.

edit this to say the unit does not charge from DC car cable either anymore. the xt60 input is not accepting any charge.
