Once a fortnight or as directed in your battery manufacturer, check the
specific gravity (SG) of each battery cell using a hydrometer, to ensure that
all cells are performing correctly and are properly charged. Any serious
imbalance should be reported to your system designer in case remedial
action needs to be taken.
Maintenance
Inverter
Periodic maintenance of your LD350-24 inverter involves little more than
checking for any obstructions to the black cooling heatsink at the rear of the
inverter. The heatsink must be cleared of any accumulated foreign matter that
may have lodged itself between the fins since the last maintenance check, e.g.
insect nests. Also verify that airflow around the inverter has not become
restricted.
Handy Hints
It is very important that you become familiar with the
functioning of your inverter. From a distance, it is not always
easy to know what if the inverter is On or in Sleep mode. An
easy way to determine this is to plug a small child's night-light
(neon type) into a power point that is easily visible, or replace
this power point with a safety type with a neon indicator. This
will indicate the inverter's operation by flashing when the
inverter is in SLEEP mode and remaining ON when the
inverter is brought ON by a load.
Batteries
1.
Every week, carry out a thorough visual inspection of all battery
wiring, taking particular note of the condition of inter-connections
between cells. This maintenance should be carried out in conjunction
with the battery manufacturers recommended maintenance.
Safety Hint
When working on batteries of such high capacity it is
essential that you wear protective clothing, some form of eye
protection and rubber-soled work boots. Please regard your
batteries with a great deal of caution, and if in any doubt,
entrust this work to your supplier / installer.
2.
Check that the stainless steel inter-connecting bolts are tight and have
no corrosion. If corrosion is evident, carefully follow the following
procedure.
•
Disconnect the system battery fuse before working on the battery
bank.
•
Unbolt the stainless steel bolts and nuts of any corroded
connections and thoroughly clean the joint with a wire brush or
file, taking extreme care not to short circuit any battery cells with
any tools.
•
Re-assemble and smear a small amount of Vaseline or similar
grease over the surface of the joint to slow down any future
corrosion.
