Check the following points to ensure proper operation of whole solar system at
regular intervals.
·Ensure all connectors of this inverter are cleaned all the time.
·Before cleaning the solar panels, be sure to turn off PV DC breakers.
· Clean the solar panels, during the cool time of the day, whenever it is visibly
dirty.
· Periodically inspect the system to make sure that all wires and supports are
securely fastened in place.
WARNING: There are no user-replaceable parts inside of the inverter. Do not
attempt
Battery Maintenance
· Servicing of batteries should be performed or supervised by personnel
knowledgeable about batteries and the required precautions.
Figure 16.1
·When replacing batteries, replace with the same type and number of batteries or
battery packs.
·The following precautions should be observed when working on batteries:
a) Remove watches, rings, or other metal objects.
b) Use tools with insulated handles.
c) Wear rubber gloves and boots.
d) Do not lay tools or metal parts on top of batteries.
e) Disconnect charging source prior to connecting or disconnecting battery
terminals.
f) Determine if battery is inadvertently grounded. If inadvertently grounded,
remove source from ground. Contact with any part of a grounded battery can
result in electrical shock. The likelihood of such shock can be reduced if such
grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
CAUTION: A battery can present a risk of electrical shock and high short-circuit
current.
CAUTION: Do not dispose of batteries in a fire. The batteries may explode.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to
the skin and eyes. It may be toxic.
