This battery is On-Grid and Off-Grid, AC & DC Coupled, Indoor or Outdoor Rated, Stackable, Safe LFP Design and UL-1973/UL-9540! The ETHOS can power 96% of homes in the USA at a price point that is HALF of most other competitors; I am very proud of what our engineering team has accomplished!

Do you have a video explaining an ac coupled battery with your ethos back up battery?

Hi, thanks for your question! To clarify so we can point you in the right direction, you're looking to understand how to connect an ETHOS stack to an existing AC-coupled system?

@@BigBattery I have SunPower panels. They all have mini inverters. That means that the power coming from my roof is AC. I am asking how your inverter deals with incoming AC.? It seems to me that it would need to be converted back to DC to charge ethos batteries. Then back to AC to power my home and the grid. I would lose some power in all 3 conversions. Please tell me if I’m wrong. Or tell me of an advantage that I am not seeing. I live in the southern ca high desert and air conditioning is a top priority I’m slowly changing out all propane equipment for heat pump or electric when heat pump is not available. I like your ethos battery backup mostly because I can start with 3 bricks and add on when needed. I like the small jump in storage at a reasonable price. Powerwalls cost a lot more if you need more than one but 2 is over kill.

​@@Skookman Thanks for the clarification! We hear you about the hassle and cost of upgrading your power when it comes to other single-unit options. The stackable, expandable design of the ETHOS is a great for an initial home system. To your question, the 12K Lux inverter(s) that's paired with our ETHOS Systems can absolutely handle any incoming AC power from your panels. These inverters feature both a standard grid connection port, as well as a second port specifically for external AC sources such as a generator or your solar panels. In regards to power loss during conversion, there will always be some nominal amount of loss during transfer for every inverter on the market, but with high efficiency conversion and fast transfer times, that loss becomes negligible. The 12K inverter we offer has a transfer time of 20 ms or less, with 95% - 99.9% efficiency so you shouldn't experience any noticeable loss of power between conversions. Plus, these inverters allow you to set timeframes where your solar panels are feeding directly to your home appliances, bypassing the battery and reducing conversion steps. Feel free to give us a call at (818) 280-3091, or send us an email to Sales@BigBattery.com, and one of our team members here can go over your current system in-depth and offer a personalized recommendation for your power needs!
