Introducing BigBattery’s 48V ETHOS Systems. These revolutionary, stackable, on-grid power systems were designed to push the boundaries of efficiency, flexibility, and reliability when it comes to powering your residential homes, cabins, and commercial offices. This Control Box, which connects to both your inverter and battery modules, regulates and monitors your ETHOS system. With just a glance, you can stay up to date on the health and performance of your power using the LED interface located on the front of the unit, which displays system voltage, remaining capacity, BMS status codes alerting you to the condition of your batteries, as well as communication configurations for your inverter. Keep in mind that this is not a battery module in itself and would need to be combined with at least 2 stackable 5.12kWh ETHOS battery modules to be a working system.

How do I connect this battery into my existing system?
These batteries use a standard
amphenol ESS connector. Each
module can be connected using the included cables. You
may also purchase additional
cables from BigBattery.
How many times can I putthis battery in parallel/series?
These batteries are not series
capable but can be connected
in parallel up to 16 times. Make
sure that the total amount of
these batteries in your configuration never exceeds sixteen total batteries. When connecting
batteries in parallel, ensure all
batteries are within 0.3 volts of
one another.
How long will my battery last,and what do I do at the end ofits life?
Lithium iron phosphate (LiFePO4) batteries can be cycled
from 3500 - 5000 times (80%
DoD, 0.5C). If you cycle the battery daily, you can get over 10
years of use from your battery.
When your battery is at the end
of its lifespan, contact us & we’ll
