Absorption LED and Float LED blinking simultaneously. Voc PV is good but total power ecxeed

Hi everyone,

I am on a charger 150/100 with 21 panels 320 Wc (Isc=9,03A ; Voc=44.6V; Vmp=37.5V). Batteries are temporarily in 24V but should be in 48V in 2 days.

There are 7 chains in parallel done with 3 pannels in series.

I read that when Absorption and float Led blinks simultaneaously, there is charger over voltage. After verification of Voc, it is below 150V. I also read that if there is too much power from PV, the controller will automatically limit the input power. My question is can I run installation during the 2 days. Is it dangerous? Many thanks for your quick answer. Please my client want to run the site
