Battery
– Charge voltage 'absorption': 14.2V / 28,4V
– Charge voltage 'float': 13.8V / 27,6V
– Low voltage load disconnect: 11,2V / 22,4V
– Low voltage load reconnect: 12,6V / 25,2V (manual
13,1V / 26,2V (automatic)
Enclosure
– Protection class: IP20
– Terminal size: 5 mm / AWG10
Standards
– Safety: 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 or 2x 36 cell in series
2) The controller switches to the lower float voltage level 2 hours after the absorption voltage has been reached.
Whenever the battery voltage becomes lower than 13V, a new charge cycle is triggered.
