What voltage is best for my off-grid system 12V, 24V, or 48V?
When more batteries, or cells, are connected in series you get higher voltage battery banks, like 24V, (25.6V lithium) and 48V (51.2V lithium). The Decisions Making Process. When trying to decide what system voltage is best, we recommend starting low, at 12V, until you find reasons why 12V would be impractical. Then, look at 24V.
