These are supposed to be taking the industry lead over life (LiFePO4) batteries, but they've got some serious
drawbacks. One is that their discharge curve is much more linear, meaning their voltage starts to crash drive
when they're around 30% charge. This may cause your inverter to trip offline due to low voltage, meaning you
won't be able to actually use anywhere near their rated watt-hour capacity.
Sodium batteries aren't going to be a viable replacement for lithium in solar and home energy. As they are now,
they're much better suited for large scale grid storage, and possibly E.V. (or even gas automotive) use. One
advantage they have over LiFe is the ability to charge at lower temperatures, which may help with E.V. use in
the colder Northern climates.
