There are other details that will appear on the screen that will assist the user to read at what point the
MPPT and batteries are
6.1
Float Mode
The
*
flashing next to the
BATTERY
indicates that the
MPPT
is in FLOAT mode
and the batteries are full.
6.2
Panels Limiting Energy
The
*
flashing next to the
PANEL
indicates that the PV panels
are limiting the amount of energy delivered to the MPPT to
charge the batteries
6.3
Equalise Mode
The
!
sign next to the
EQUALISE AT
line indicates that the
batteries are being charged in the Equalise mode and the
batteries have not reached the
“
Equalise Voltage
”, for every
12volt in the battery pack, system this would be 15 volts
Once the batteries have reached the EQUALISE VOLTAGE
then the display will change to
This shows that the battery is at the
EQUALISE Voltage
and that the MPPT is in the 1 hour bulk charge mode.
6.4
Boost Charge Mode
When this is complete the charger switches to the
BOOST
mode and will hold the voltage at the programmable value
say 14.5 volts until the charge current has fallen below the
programmable BOOST amps, say 5.0 amps
When the charge current falls below the programmed value
of say 5.0 amps,
The screen changes to
6.5
Float Mode
This shows that the
battery is in FLOAT mode
and is
Indicated by the flashing
‘*’
