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 any time 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 blinks
indicates the LVD currently applied.

reaches the normal range.
Wait until the battery voltage reaches the
correct level.
Push the ON/OFF button to reactivate the
inverter. 1.25*Unom
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
inverter.
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%).
