Which FlexoLink Cable Length Do You Need?
Cable length, temperature and panel voltage all affect how much power actually reaches your battery. Longer runs and higher temperatures increase resistance — and resistance means loss. On a hot African summer day with a long cable run and a low-voltage panel, those losses add up fast. Less power at the battery means slower charging — and a longer wait before you are back at full capacity. The fix is simple: thicker cable over longer distances. Use the table on the left to match the right FlexoLink to your FlexoSun panel and setup.
