Absorption Charge Mode
As the inverter continues to run on nominal AC input (shore power / genset),
and the batteries have been successfully “bulk” charged, the inverter will enter
the second stage of charging. The inverter’s green LED will flash once every
second (fast flash) to indicate absorption charging for 1 – 3 hours, depending
on the battery bank selected (see separate ME “Remote” manual for selection
information). The charger then switches to it’s final mode.
Float Charge Mode
As AC input (shore power / genset) continues, the inverters green LED flashes
once every eight (8) seconds (slow flash) to indicate the third and final state
of charge. The batteries are held at the “float charge” voltage (13.6 VDC GEL,
13.1 VDC for AGM, and 13.4 VDC for liquid lead acid) as long as AC is
present at the inverters input. Float charging reduces battery gassing,
minimizes watering requirements (for flooded batteries) and makes sure the
batteries are maintained at optimum capacity.
Battery Saver Mode
This mode is designed to keep batteries fully charged over long periods
(storage) without drying them out. When the charger is in the “float” mode for
over 4 hours with no DC loads running, the charger will turn off. If the battery
voltage dips below 12.5 VDC, the charger will automatically initiate the
“Float” charge mode to return them to full charge.
Inverter Fault / Alarm Conditions
Fault / Alarm Conditions
The inverter monitors the incoming AC power (shore power / genset), the
batteries, and itself. Whenever a condition occurs that is outside the normal
operating parameters, the inverter will take the necessary steps to protect your
appliances, batteries, and itself from damage.
Low Battery
Whenever the battery voltage reaches a low level (programmable from 9.0
VDC to 11.0 VDC), the inverter will initiate “Low Battery Cut Off” (LBCO),
which automatically shuts the inverter down, along with all connected loads,
to protect the batteries from over discharge damage. The green LED on the
remote panel turns off, and the red “Fault” LED turn on to indicate the fault
condition.
