Maintenance 

 

3.

 

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. 

Inverter 

Periodic maintenance of your LD450-12 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.
