System Voltage
12V
Why this matters
12V systems are simplest but limited to ~2,000W. Good for small RV/cabin builds with short wire runs.
Battery Chemistry
LiFePO4
Why this matters
LiFePO4 (lithium iron phosphate) lasts 3,000-5,000 cycles, handles 90% depth of discharge, and won’t catch fire. The gold standard for off-grid.
