How to expand the capacity of a Bluetti EB150/240 with external batteries.

I'm building out a new on grid/off grid backup power system for my house so I thought I would show how to charge/expand a Bluetti Eb150/240 with external batteries while I had 2 free ones waiting on my project.

I did something similar. I bought 4 - 50ah Power Queen batteries . 51.2V in Series, it charges my Ecoflow Delta 2 at 500 watts.

I was thinking of doing something similar with 24V and a Bluetti EB3A. Nice to know it works!

Absolutely do this scenario with a eb70s, and talk more about different ways to charge up the batteries. All options please, thanks for sharing.

Thanks for this. I've done the 12/24 step up converter and ran a Bestek 300w pure sine inverter connected to the ac brick. Another way is to get a AC200p 400w ac brick with a higher watt inverter to the EB150 port. The EB150/240 are great machines, too bad Bluetti discontinued them.

I wish there was a way to attach batteries like this that charge like the over priced expansion batteries most companies sell.

@jw3843 Жыл бұрын

I would say this is great for emergency situations or just to prolong the use of the power station without paying the high price for the units with expandable batteries. For this model I would recommend 4 batteries in series to max out the charging input around 48 to 52 volts since this model can take up to 60 volts and up to 10 amps charging. It would work great at night when solar is not available or you can have a good size solar charger and solar panel set charging the batteries while charging the power station and running something like a window unit for longer run times.

you can charge while you use the inverter, right? So effectively is like having a bigger battery

@@jw3843 how is that possible? i thought most people with expensive setups or few batteries have solar charge controller and inverter connected all the time.

@jw3843 2 ай бұрын

@@user-rp1vu1gk5u All you have to do is use the batteries as solar input to the power station which will charge the power station like solar would. The older version of bluetti ones only take dc input. The easy way would be to use the solar charging cable, connect them to the batteries and use the charging plug for the power station. You can still have the batteries connected to a solar charge controller during the day. If used for this purpose you would not need to have an inverter separate from the power station. Of course, if you have the batteries set up for 48 volts, then you would need a solar charge controller made for 48 volt batteries.

THANK YOU! I was considering doing something similar using 2x 50AH 12V batteries hooked up to a Bluetti EB3A exactly like that. I was considering the Redodo 50AH 12V ($170), two of which fit perfectly inside a Milk Crate box topped off with a plywood cap the EB3A would sit on (I don't like messy wire setups).

I have the 240 and went with the B300 and have 800 watts of solar running the system - my concern is leaving the inverter on 24/7 to run the fridge. We will see how this goes - I can't protect the 240/B300 - the temps in the cabin run 14F to 125F - let the games begins. Like your set up and would likely do similar later but with an inverter not a solgen and use my solar, or new solar. I like the panels are getting smaller but more powerful too - don't have the real estate to cover with panels right now. So less being more is nice. Costs are leveling off for the short term, so I best bite soon.

Scroll to 6:30 in the video. You need an external charger.

@uhjyuff2095 Жыл бұрын

if using solar to charge all the batteries you would need another solar charge controller for the external batteries and might as well get a few more panels too. So you need more batteries, more chargers, more wires, and more panels. So its like you just need two complete solar generators minus the second inverter.
