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.
