AGM BATTERY BANK

48 VOLT SYSTEM

CHARGER:

Battery type = Custom

  • Absorb = 57.6
  • EQ= 57.6
  • Float = float = 53.6
  • Absorb time = 3 hours
  • EQ time = 12 hours
  • Final charge stage = Multi
  • Max charge rate = 100%
  • Max charge time = 18 hours
  • VAC dropout= 100 VAC (if a good generator)
  • EQ reminder = 15 to 30 days

 

BMK:

  • To your battery bank size
  • EFF= Auto

 

AGS:

  • Voltage start to 46.0 for 2 minutes
  • Voltage stop to 55.0 for 120 minutes
  • SOC start to 50%
  • SOC stop to 90%
  • Charge to 100% every 14 days

 

INVERTER:

LBCO= 44.0

AC in  , depends on gen size, typically a few amps below the generator breaker size

PT 100 should be linked when you connect.

Once or twice a month after the batteries are at 100% or in float mode push and hold the charger button for 5 seconds while the generator is running and this triggers the EQ mode. Then in this state with gen running needs to be running for 7 to 12 hours depending on the typical SOC level you go to. Once you have solar you can push both buttons on PT100 and it will do this but there needs to be a full bank of batteries and this should be done every 14 days in the sunnier times. This depends on the loads you have going at the time and the amount of solar. The batteries need to held at the EQ voltage for 7 hours minimum every two weeks
