This strategy will off course restrict the use of
the battery and drive the user to reduce his
consumption or to increase the production (by
an additional charger
backup generator for instance).
When the battery voltage is higher than
1.08*Unom (13 V, 16 V, 52 V) during 2 hours,
the LVD is progressively stepped down by a
decrement of 33 mV/cell (0.4 V @ 12 V). This
process insures that the average charge of
the battery is sufficient (over 50 %) to assure its
optimized lifetime.
This function is particularly useful in solar home
systems where the battery is sized in 3-5 times
the daily average production. For instance a
200 W solar system producing 800 Wh/day
connected to a 200-300 Ah / 12 V battery.
If the battery is sized so as to be fully
discharged and charged every day, it may be
possible that the restriction of use implied by
the permanent increase of LVD is not wished.
We recommend then to deactivate the
Battery Lifetime Optimizer.
Maintenance
The inverters of the AJ series do not need any
special maintenance. The casing may be
cleaned with a damp cloth (not wet).
In the case of malfunction or mechanical
deformation, the inverter should be sent back
to the manufacturer for control carefully
packed in its original packing.

Before deciding to send back the inverter,
check the following points:
• The battery
is
accordance to the nominal input
voltage of the inverter.
• The consumer devices do not have
any defect or overload for the inverter
BLO
(to make sure, disconnect them).
Should you contact your salesperson, note the
following points before calling:
(You will find this information on the label
underneath the inverter or at the cable side)
• Exact model
• Serial number
• Power of the inverter
• Nominal input voltage of the inverter
In case the inverter should not be sent back in
its original packaging, it should be packed in a
a
stiff carton box and be well protected on all
sides by means of an anti-shock and isolating
layer of min. 5 cm thickness. A weak
protection may cause damages to the
inverter during transport and are not covered
by the warranty.
