be kept in a cool, dry, and ventilated environment.
Battery maintenance operators shall have the knowledge and technical skill for battery maintenance;
All batteries connected in parallel should be of the same model and have same firmware version. This pay
attention to this requirment particularly when replacing batteries or modifying an existing energy storage
system.
HYD-ES inverter is transformer-less, therefore the positive and negative pole of the PV array are NOT grounded.
Otherwise it will cause the inverter to fail. In the PV system, all non-current carrying metal parts (such as: PV
module frame, PV rack, combiner box enclosure, inverter enclosure) should be connected to Ground (PE).
Warning: Do not disassemble or break the battery. The electrolyte inside is toxic and can cause damage to skin
and eyes.
Warning: follow the following rules during battery installation/maintenance.
a)
Take off your watch, ring, and other metal objects.
b)
Only use tools with insulated handles.
c)
Wear rubber gloves and shoes.
d)
Do not put tools or metals above the battery.
e)
Switch off HYD-ES inverter & batteries before connecting / disconnecting battery terminals.
f)
Battery positive/negative poles should be isolated from ground.
