I have a Multiplus 24/3000/70 and I noticed the Bulk light flashing whilst I had been running my generator for about an hour and the genny showing a zero load. I could not find this condition in the user manual. I have had this set up for 15 years so this is not a new thing for me to do. Later on I started the genny again and no flashing Bulk light and normal charging. What was the flashing light about? Any help appreciated.
