This is terrible advice. A DIY system such as this offers way more capability, expandability, and repairability. All at a much cheaper price

The Ecoflow is locked into a proprietary system for expansion batteries and if something like the inverter or BMS breaks you pretty much have to trash the entire system.

The Ecoflow's advantage is for portability but for home storage, DIY systems are the way to go. Unless the Delta Ultra is on sale

This can easily be built into a "power bank" with 5kWh of capacity if you just add a string of 4 100 ah 12v batteries in parallel for a total of around $800. Obviously not portable though, but easily less than half the cost of a pre-built power bank with the same capacity.

ecoflow river3plus has 400watts continuous 800 peak and better investment if you can live with that low

delta3 much better investment imho

wifi/bluetooth monitoring, etc.

Considering adding this to the EW 165AH 12V metal case battery, should sit right on top, or I can secure it somehow to the top (metal case has a handle on it). This gadget allows 1K watts out, up to 55 amps in (battery charging), for a reasonably quick recharge, so nearly perfect for a smallish camping/travel rig. Could compliment a larger van rig/RV, but sized well enough for pickup/overlander/Jeep....

Yeah this can be a good solution for someone that wants to keep a fridge and some electronics running in a power outage.

Just order the 4 * 314 Ah cells here:

And for $630, you have 4kWh of storage

Instead of AC, can we use Solar panels to charge the batteries using this inverter?

If you used the Eco-Worthy only as an inverter, and not as a charger (in other words the Eco-Worthy would be connected to batteries, but not plugged into A/C), you should be able to do this. However, you would also need a solar charge controller between the panels and the batteries. In this mode, you would also likely lose the 20ms UPS function of the Eco-Worthy.

You'd need a separate solar charge controller to do so.
If you want an 'all in one' unit, look at Hybrid inverters - they'll have the AC -> DC battery charger, DC -> DC solar charge controller, and the DC -> 120V AC inverter. They do tend to consume more idle power than inverter-only units though.

Did you add a BMS?

Sorry for my ignorance -- if I was looking to create a UPS/backup battery for my server rack, would this + Eco-Worthy LiFePO4 rackmount batteries be a good solution? The 20ms switchover from grid should not be a problem. There would be no solar in the mix. Do I need a BMS?

Rackmount batteries would have a BMS inside, but the reviews on Amazon suggest this is not well engineered: reversed hot-neutral, non-serviceable fuses, reliability issues? It may work--until it doesn't.
Edit: Oh, and 95% of rackmount batteries are 48V, which would NOT work with this unit...

Thanks, Prof --- that's really helpful. I'm both shocked and somehow unsurprised that these batteries have those sorts of issues, especially given how much they show up here on SD. You have any thoughts around piecing together a DIY rackmount UPS with LiFePO4 batteries? I'm sick of the SLA lifespan, but I can't justify the cost for the native lithium UPS units from APC and others. :-\

The Delta3 can take 500watts input continuous via xt60 which is open/cheap standard

Delta3 1500 right now is $450+tax with the new extra ebay 10% coupon

https://www.ebay.com/itm/146448954017

That's a massive battery and it has 5 year warranty when registered with ecoflow

the inverter on that can do 600-1000 watts continuous or 2000 watts burst

15ms switchover which is faster than this

and it has fans and mppt and bluetooth and wifi interface

at full price of $700 it would not be worth it but for $450 it beats DIY

This inverter does not have fans? It clearly does lmao.


And just having an XT-60 solar input (which actually you need the EcoFlow XT-60i to get max current input) is not at all similar to a truly open battery and inverter setup. You literally need just standard wires to connect the batteries with the inverter. You can expand the system as much as you like. And quality LFP 12v 100Ah batteries are ~$120 now, so EcoFlow looks crazy overpriced in comparison.

If any of these individual components fail in the EcoFlow, you need to send the whole unit in for costly repair.
