System Voltage
48V
Why this matters
48V is standard for large systems (5kW+). Lower current means less copper, less heat, and better efficiency over long 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.
