The Genius LED indicators are flashing red and green as it is most likely that you have solar panels connected to your caravan and your battery is either full or nearly full.
In this situation the Genius is only required as a power supply and not a battery charger. The red and green LED indicator flashing occurs when the battery voltage is higher than what the Genius requires.
Example: The input amps from the solar panels are high enough to power the caravan (based on current amperage draw). There is no harm to the unit caused by this situation.
If your Genius LED indictors are flashing red and green and you do not have solar panels connected, please contact BMPRO customer service.
