• EMC EN 61000-6-1, EN 61000-6-3, ISO 7637-2

1) Use 36-cell solar panels for 12V. Use 72-cell solar panels for 24V or 2 36-cell solar panels connected in series.

2) The controller switches to the float voltage level 2 hours after the absorption voltage is reached. Whenever the battery voltage drops below 13 V, a new charging cycle is started.
