CHARGING STAGES
(continued)
Stage 1:
Direct solar energy to charge the battery until the battery voltage reaches 14.5V, switches to stage 2.
Stage 2:
Overpressure pulse charging, when the battery voltage is lower than 14.5V, charger pulses for 1 sec on and 1 sec off. This will occur for 2 hours, or until 14.5V
average is reached whichever comes first. Then will switch to Stage 3.
Stage 3:
Pulse floating charge, pulse 1 sec on 1 sec off at 13.8V
Stage 1:
Charging with increasing voltage and constant output current.
Stage 2:
Perform constant voltage charging at 14.5V, when current is lower than 3A, switch to stage 3.
Stage 3:
Performs float charging with 13.5V. If batteries voltage drops below 12V, then switches back to stage 1 for recharging.
Stage 1:
Charging with increasing voltage and constant 30A output current.
Stage 2:
Perform constant voltage charging at 14.1V, when charging current is lower than 6A, switch to stage 3.
Stage 3:
Performs float charging with 13.1V. If battery voltage drops below 12V, then switches back to stage 1 for recharging.
