Can I charge an Ecoflow Delta 2 with a Victron 100/15 Solar Charge Controller?

[alderotes]

Delta 2 has a 500w, max 60v 15a input. Victron solar charge controller is 100v, 15 amps. I have 2 200w solar panels with 36.4 Voc and 6.6A Isc specs. If I tell the Victron SCC that the Ecoflow is a 24v battery, can I use that to charge the Ecoflow Delta 2?

Otherwise, I have to physically change the solar panel connections when switching from the Ecoflow to charging my 24v LiFePo4 stand alone batteries.

Thank you.

Does the Delta 2 have a built-in SCC ? The 60v rating may suggest so. The Victron 150/15 must be able to sense the internal battery voltage which it will not in this case. You should be able to connect your solar panels directly to this Delta 2 input.

I have a similar battery setup as you. What I did was install dual DC breakers between the panels and batteries. Then jumper the inputs together and switch on whatever battery bank you want to charge. This is the breaker box I used: https://www.amazon.com/dp/B0B5R2LQ4C/

A more expensive, but foolproof alternative would be to use a pre-made MC4 switch. RevoPower makes this one: https://revopower.us/solar-hybrid-switch

Yes you could definitely do this, the DC input on the solar generator/power station does not care where the voltage comes from.

Any DC source below 60V is acceptable.


If you're planning on doing this though, your best bet would actually be to just wire your 24 volt battery directly into the EcoFlow permanently through the PV connector.

That way you'd just keep the charge controller only connected to the external batteries and it'd be powering your usual loads (whatever you were using the 24V bank before) and keeping the Delta 2 constantly topped up at the same time with about 375W of power.

I appreciate the responses. What I'm hoping to do is set up a charging station that I can bring each device to (I have multiple Ecoflows and multiple 12 and 24v batteries). So downstream of the Victron SCC, I would be connecting an Ecoflow, charge that, connect another Ecoflow or a LiFePo4 battery and charge that, and mix and match as needed. So the solar panels and the Victron would be charging either an Ecoflow or a battery until they are all charged.

The controller will be happier if it always 'sees ' a battery. I suggest , controller - battery - Ecoflow.

Does your controller have a load output?

If so it runs at battery voltage. Just use an xt60i pigtail from load output to the ecoflows.

24v x whatever amps the load output allows to be drawn..

It might not be full charging speed but it will protect your battery bank and requires minimal work of just moving the xt60i to another ecoflow.

 

[alderotes]

KnobCountry, so you're saying to charge the Ecoflows from the load output (My Victron has that) and the batteries from the battery terminals? I have XT60i pigtails on all my batteries? All I've ever read about the load outputs on Solar Charge controllers were they are for a muffin fan or led light, something that draws only milliamps. I'll look into that. Thank you!

This is exact way I have my setup. Solar panel to my Victron charge controller. Controller to my battery then I connect the battery to my ecoflow Detta 3 Plus. 2 runs of wires from battery to both solar inputs.

Encox, How do you like your delta 3 plus?
Have you had any issues with charging it from a battery through the solar inputs?

Do you ever disconnect the battery? If you left it connected it at night, I’m assuming the battery would die. Sun rises in the morning and let’s say Victron starts charging the battery at 50 watts. Does the EcoFlow charge at 50 watts or keep shutting down the BMS?

In my case I run all of the loads through a "Victron Battery Protect" that I have set to a specific low voltage cutoff point.
That way nothing can train it to the point of the BMS shutting down.
