ATTERY IFETIME
Cycling a battery in permanent charging
mode from 0 to 30% is often a cause of early
aging of batteries, particularly in solar home
systems.
In order to enhance the battery lifetime, the
AJ inverters are equipped with a unique
function that will readjust the low voltage
disconnection (LVD) threshold according to
the behavior of the user consumption. This
allows a full recharge of the battery.
This function can be activated at anytime as
per the procedure described p. 8.
An indicator (green LED 2) only available on
from AJ 275-12 to 700-48 is lit or blinks when this
function is activated. The number of blinkings
indicates the LVD currently applied.

Eliminate the short circuit.
Push the ON/OFF button to reactivate the
inverter.
Use the inverter only in the range of its
nominal power. Regular use in overload
power diminishes the lifetime of the
inverter.
Push the ON/OFF button to reactivate the

Back to manufacturer for testing.
If this indicator is lit continuously, this means
that the use of the battery is correct and that
it was well charged. The LVD is then set at
0.87*unom (10.5, 21or 42V) as per the model.
This also means that you have the widest
availability of the energy stored and that your
battery is likely to last longer.
If the indicator is blinking one or several times,
this means that the use of the battery is
restricted and that the disconnection voltage
was set according to the table below (+/- 2%).
