Bigbattery Ethos

[rsmiele]

Has anyone looked into the new Bigbattery Ethos stackable batteries? They look like an alternative to the EG4 PowerPro except the price per kWh is high. Bigbattery also resells their version of the PowerPro as the Rhino 2. I plan to mate these batteries with the Luxpower 12kw inverter ( aka EG4 18kw); approx 30 kWh battery storage total. I like the ease of the stackable concept for installation and expansion, the the price premium is too high. Thoughts?

Bigbattery Ethos $375 kWh

EG4 PowerPro $265 kWh

Will, please add Ethos to your list of batteries to do a review to review.

Would love to see Will do a review on these

Just got an email from SS about them, interesting but not compelling compared to the EG4 18Kpv/PowerProWallMount ESS. https://signaturesolar.com/big-battery/
Lower weight per battery is good, 114# per module compared to 305# for the PowerPro, but other than that I got nothin...

I would rather have 1x 280Ah than 3x 100Ah modules.

They are actually heavier than the LL-S series. And price is higher, as noted.

I prefer the 100Ah versions as you can swap them out (lower cost and effort) if one were to go bad.
