Hi, I set up the 15KVA Quattro as a UPS with a battery capacity of 48V 400Ah.
Install on a work boat
Want to know the following:

  1. When will the battery be auto recharge? From the manual it wrote, “SOC drop 5% or more below the value of min SOC in the ESS menu.” As we did not turn on the ESS mode, when will the battery be recharge?
  2. When will the battery enter float mode? We did a test for 5 days and we still did not see it enter float mode
