This was delivered few days back, the DURAVOLT 18inches AC/DC fan, having used cloud energy for about 6 months before the motor gave up, I have to say the highest speed of the cloud energy is almost the same with the least speed of this DURAVOLT, maybe this is as a result of their power consumption being different, 25watts/15 watts, and the cloud energy being 16inch. I'll update again after 6 months 😆

Secondly, so some solar padi I just made let me try my hands on a Cworth 12.5v 100ah lithium ion phosphate battery, oh well I wasn't surprised with the performance when connected to the Ecoflow to charge through the solar input port, the battery being 12volts, and Ecoflow pulling 8amps, it only charged at 100watts.
I have a River2pro that can pull up to 220watts (dc charging )but not from a 12.5v battery.
So, the advice goes thus, like I have said before, when you want to increase your back up time by buying a third party battery, make sure you're buying at least a 24v battery, the 12v won't cut it, charging at 100watts is like not charging at all, and the system would eventually auto shut off and you run the risk of damaging the inbuilt battery of the Ecoflow power station if you have a load as little as 80 watts connected while this extra battery is plugged in, not worth it, get at least the 24v.
Now, I am looking at this brand making the news, colarsolar, saw a 24v 3.5kwh battery of this brand for 490k.

Nice one there. I have some questions...
1. How do you charge the external battery? Ecoflow or external source.
2. When being used together, which battery drains 1st? Ecoflow or external battery.

1. How do you charge the external battery? Ecoflow or external source.
2. When being used together, which battery drains 1st? Ecoflow or external battery.

I didn't try this experiment with a charger for the external battery, but on YouTube, people who have this setup installed have dedicated solar s for charging this battery ( total wattage of s depends on the total voltage of charge of the battery, battery capacity) and then these solar s are connected to solar charge controllers to charge the battery and then the battery is connected to the power station through the O ring to xt60 cable.
The external battery drains first, look at the external battery like the sun, just like when the power station is connected to a solar and in use, if the load on the power station is less than the power coming in from this external battery, then you get a 100 percent charge, it tops itself up and then repeats, if the load is more than the total power coming in from the external battery then the Ecoflow battery starts to drain very slowly, just like what happens when connected to the s, heavily loaded and in use during the day.
This back up trick is great, no losses from this external battery as it is DC to DC you get to use 100 percent of its total capacity, only loss will be the normal inverter loss from the Ecoflow inbuilt inverter, I'm looking at a 3.5kwh battery 😆 I want 24hrs now.
This has been rewritten properly, the Ecoflow power station battery doesn't get emptied before the external battery, the external battery is emptied first, this external battery only tops up the Ecoflow's.

How many speed settings does it has? I got one yesterday for my mum with 3 speed settings and the least speed is crazy. I want the one with at least 5 speed settings. I would have preferred Qasa but she doesn't likes it because it does not has turning knob 😀

Three speed settings sir, and the airflow on the least speed setting is still a lot, especially on a cool night.

Has anyone try colasolar??

I’ve been using the Hithium Hero EE1 for abh two months. It’s been particularly useful although I haven’t connected it to the changeover to carry the lighting and ceiling fans in the apartment. I haven’t also bought solar s.

I only connect an extension to carry a 58” TV, 125watts and a 60watts standing fan (I use it at lowest speed) which might not be up to 60watts.

With load of abh 185watts, the Power station still manages to give me 3hours on each bar. Totalling more than 10hours to drain.

Can any solar engineer help me connect it to run the house fixing the solar ?

This won't serve you good, you'll only be able to charge at about 100watts max, that'll take forever, won't be able to top up from this battery while loads are connected to the power station, get at least the 24v, and from my market survey, it does seem there are many brands offering higher capacity batteries (wh) for just a little over the price Ecoflow is selling it's 12v battery.

That sounds pretty good. I currently have the Delta 2 (1kWh), but it doesn’t last very long for my needs. I haven’t connected it to solar for charging yet. I’ve been considering selling it to get the Delta 2 Max instead. However, after reading your review, I’m now thinking it might be better to just get the ColaSolar 2000 (2kWh) as a backup for when my Delta 2 runs out. My only concern is that their power stations are so cheap—I just hope they’re not using low-quality materials that might fail within a year.

I’m buying ColaSolar(2Kwh) in a few weeks time for the apartment since it gives a 1kWh output unlike Hithium. I’ve spoken to a seller, he says the ColaSolar 2000, two s and the wire is 780K.

I’ll give it a try. I just don’t know how much for the installations.

I could see a backup use case for the Cola.

Your fears are valid.
Off-brands are a dream when they're in good working order.
But when you do need to report something or make an inquiry, you'd pull your hair out.

To be clear, they're all Chinese (primarily Shenzhen labs).
A 100% markup is a lot when they're sourced from the same factories.
You'd have to decide whether the better internals (everything from efficiency to protection/controls is objectively better), better customer service (you intuitively know which brand is more likely to send a replacement unit over splitting hairs about warranty coverage), and a large community (very helpful) is worth a 100% markup.

If you're getting the Cola to serve as a backup, start planning out your modular solar buildout in earnest.
As it is anyone's guess how many years you'll wring out of it.
Unless you buy a dud, it'll def pay for itself. But do not set lofty expectations.

I used the car charger that came with my river 2 pro as I couldn't find the XT60 to MC4 cable.

It's showing that it's charging from a car while it's my solar that's connected and it's not giving more than 70W for a 200W .

What could be the reason?

The reason is because you are not using the right cable,

Ensure to get a proper mc4 to xt60 cable or whatever it is required for your river
And the right solar extension cables too.

I am happy to announce to you,even if you use a delta 2 max,you would have the same issue.

Power stations even though they are made to work like a bigger capacity power bank,are not totally meant to work like one that would depend on only grid charging.

Get your self a proper jinko required for your delta 2,

My delta 2 powers my whole apartment 24 hours and I have enough juice to last me tru the night.

Simply because I run heaviest appliances during peak period when sun is blazing and reduce my usage at night.

Even tubular batteries without solar would be very ineffective.

Rather than get a cola,use that money invest in a proper jinko and a delta 2 extra battery,
That's doubles your delta power to 2048kwh.

580w - 620w and enjoy your delta 2.

@nurez305
Get a if it is not impractical in your location.
It's a no-brainer.

Is it a single Delta 2 that powers ur entire apartment for 24hours? What’s ur average load wattage, and what capacity of Jinko solar s are connected?

Everyone knows how useful solar s are for charging batteries without relying on the grid. The real challenge isn’t getting the s, but finding a space to install it. This is the main issue in a rented apartment.

If not for space, I would have done proper solar set up instead of buying a power station. For now I still rely on grid to charge

Yes a single delta 2 powers it,

Runs my large screen tv,home theatre,fridge,freezer,all fans(ceiling and standing),and on some crazy hot days,my AC too
I use a 585w jinko .

You can fabricate a solar rack stand to accommodate your ,also talk to your landlord to confirm if he would allow you install.
Solars are meant to be installed on roofs,
Not sure homes are built without roofs

With just 1kwh 😳😳, that's huge

nurez305:
With just 1kwh 😳😳, that's huge

You are missing the point,
The sun does all the job,
My battery continues to charge as long as the sun is up,
So by the time the sun goes down,I am mostly on full charge.

nurez305:

Delta 2, although 1KWh, it has an output of 1800watts. Unlike the Hithium Hero EE1 dah has an output of only 200watts.

Then again, connecting with solar s means you can use things while the sun is in its peak while the station also charges for backup.

My general load is 640watts (58” TV, Two Fans, Decoder, 4bulbs, PS4, Refrigerator), The Refrigerator and PS4 will be during peak hours, both aside, my load would be abh 305watts.

Switching off the TVset and lights at abh midnight, I’d have only 120watts to handle, exactly why I believe the ColaSolar would deliver. Its output is 1000watts

noobody:

how will sun do all the job? Total solar input for delta 2 is 500watt, Ac alone will take minimum of 700watt. How will 500 watt input take over that output??

Babatundehy:


Three speed settings sir, and the airflow on the least speed setting is still a lot, especially on a cool night.

Thanks, I might consider getting another one for her because the least speed is too much compared to Qasa with six speed settings.

The 500W solar charging is pretty fast!!
As long as you are, getting max input from your solar,
Leave the,delta 2 and the sun to worry about that
I mentioned also,I use my AC on very hot days,I did no say I use it daily.

My thought exactly.

Delta 2 is 1000watts, let’s say it’s at 0% and starts charging by 11am at Sun Peak (500watts/hour) with a load of 260watts(1 TVset, Two Fans, 1 bulb), the PowerStation should get only 240watts/hour.
(Except this isn’t how it works)

In 4hours, the system should be full and ready for night backup.

At night, let’s say from 7pm, u connect 4bulbs(60watts) and two fans(120watts) totalling (180watts), in abh 6hours ur backup should be exhausted.

and he also mentioned AC when the weather is very hot. No matter how hot the weather is, the input can not exceed 500watt. So how is it possible to get your battery charge that way?
