Battery maintenance workers must have the skills and knowledge required to carry out this activity.
All the batteries connected in parallel must be of the same model and have the same firmware version. This
problem must be taken into consideration by the designer/installer, especially when replacing the batteries or
when modifying the existing storage system.
The HYD-ES inverter does not have an isolation transformer so the positive and negative poles of the PV string
do NOT have to be grounded, otherwise the inverter may be damaged. All non-current-carrying metal parts
(such as the PV module frame, PV rack, housing of the combiner box, and housing of the inverter) in the
photovoltaic power system must be connected to the ground.
Attention: Do not disassemble or puncture the battery. The electrolytes in the battery may be toxic and cause
damage to skin and eyes.
Attention: during installation and maintenance of the battery, please follow the rules below.
a)
Remove watches, rings and other metal objects.
b)
Only use tools with insulated handles.
c)
Wear rubber gloves and shoes.
d)
Do not place tools or metal objects on top of the battery.
e)
Turn off the HYD-ES inverter and batteries before connecting/disconnecting the battery terminals.
f)
Both the positive pole and the negative poles must be insulated from the ground.
