STANDARDS
Safety: EN60335-1, IEC 62109-1
EMC: EN 61000-6-1, EN 61000-6-3, ISO 7637-2
1) For 12V use 36 cell solar panels
For 24V use 72 cell solar panels and
cells in series
For 48V use solar panels 2 to 72
cells or 4 x 36 cells in series
2) The controller switches to lower float voltage
2 hours after reaching the absorption level.
As soon as the battery voltage drops below 13V, a new one will start
charging period.
