15. Maintenance & Cleaning
Check the following points to ensure proper operation of the solar system at regular
intervals.
Ensure all connectors of this inverter are clean.
Before cleaning this inverter, be sure to turn off all the breakers [AC breaker,
battery breaker / fuse and PV DC breaker / fuse(s) ].
Clean the inverter, during cool times 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 to
service the unit yourself.
Battery maintenance
Servicing of batteries should be performed or supervised by personnel knowledgeable
about batteries and the required precautions.
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
: Batteries present a risk of electrical shock and have extremely high short-circuit
currents.
CAUTION
: Do not dispose of batteries in a fire. The batteries may explode.
CAUTION
: Do not open or damage batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.
