Ecoflow mobile battery

[toto64]

Hello everybody
I would have liked to make a mobile inverter like the ecoflow Delta-pro.

The use would be for a pellet stove or the consumption would be 300w for 15 minutes then 75w for 5 hours.
At the moment I don't have solar panels.
I have a generator. I would like to use this mobile battery to filter my generator current.

I find information in this doc:
https://www.victronenergy.com/upload/do ... ual-fr.pdf

It remains too vague for the moment, a Phoenix converters, a BMV battery controller from victron and a 2.4kWh Pylontech Lithium battery, I find it difficult not to over or undersize elements.

Overall what do you think of this project?
It's useless, it already exists or it can allow you to make your DIY charger/battery system.

Looking forward to reading you.

hello, it smells a bit like disguised advertising, but so be it.




If your need is to provide electrical service for your pellet stove, assuming it plugs into AC220V, just buy yourself
* a 12V battery charger
* a 12V battery preferably slow discharge, 50 Ah or more
* a 500W "pure sinus" inverter (DC12V to AC220V)
* an electrical outlet to be wired to your stove

and connect all this in cascade from your EDF network

Given the risk of power cuts for this winter, this assembly may be useful!

Budget level?

Remundo 300 vs Victron 2000?

ps: why an electrical outlet? There is at least one on the inverter...

[Remundo]

I was talking about a male plug.

maybe the inverter does not have a male plug (connected via domino or on circuit breaker)

vui for the budget is about that.

An old pc inverter, new batteries, because I think you have to aim for 1000VA, possibly help out with old car batteries, which can still go for that, but unable to start a car, but it will not hold years ...

But you have to have a mini juice available, that's just to protect yourself from breakdowns...

But pokey budget, like 50€ for the inverter, we find some, and maybe 50-150€ for new batteries, for a short autonomy....

I think that now a slow discharge battery, in 100Ah, it must be between 200-300€ for one, to see how many you need.
But there, if it is for solar production, the pc inverter is to be forgotten I think.

Thank you already for your comments.
for disguised advertising, I understand I chose a brand of inverter which is known to enlighten me on the subject.
For the Ecoflow and co gadget, the reviews on the product are not sufficiently highlighted, but I consider them prohibitive to buy this type of product.

For the project I actually have a pc inverter lying around in my garage I will first check if the power of 300w is possible.

Concerning hybrid inverters transforming solar panel or generator to a battery and then restoring this energy.
For the moment, I found it very difficult to configure and the continuous consumption of these devices is around 50w. Which is nothing.

[phil59]

Attention, 300Wh in starting power, it can be a peak of 600-900W at start-up, which is classic, for a few seconds max, but to be seen....

[Petrus]

It is also necessary to see if the pellet stove will react well to the square signal of an inverter for PC.

Hello,
According to your data, it takes about 1 kWh/d and therefore at least 500 W of panels to ensure the winter months https://re.jrc.ec.europa.eu/pvg_tools/en/

It must be a universal motor, we should see if it is not possible to supply the stove with DC, which would reduce losses.

a 500W "pure sine" inverter

For example ?

[toto64]

Alright, I'm moving slowly.
For the Pc inverter, actually the garage one has the following characteristics:
input 220-240Vac, 4,5A P.out 480w, 800VA

For phil59, if there is an inrush current, I don't know if it will pass. It is the resistance that heats the pellet for the start, then it is only an endless screw.
For izentrop, no photovoltaics planned. I have a gas generator.
For Petrus, I think Remundo came up with a pure sine for that reason. The electronic board won't like it, you're right to point that out.

I want a solution to power a pellet stove when there are power outages.
It's nice these exchanges, I did not think at all of a solution to a PC inverter.

For Remundo, thank you for your description, it's very constructive.
1-a 12V battery charger connected to the battery (8A)
cost 30€
2-one battery 12V 110Ah AGM battery slow discharge Deep Cycle SC 110 marine
cost 220€
3-1000W Pure Sine Car Inverter DC 12V to AC 230V Conversion
cost pure sine 1000W 170€

So the DIY solution would cost around 420€ with battery.

I do not count the wheels and the wood for the dressing.

One note though, a low-end 2,4kW Hybrid Inverter costs $300. In this case the converter 220v --> 12v then 12v --> 220v costs 200€
it is the same range but the power available is 1/2 of that of the inverter.
If you have links for purchasing the items, I imagine the quality will be different.
