Safety
A1-HYB-G2 series
inverter is designed and certified to meet stringent Ul1741/IEEE
1547 and ANSI/IEEE 62.41/62.42 lighting and surge requirements.
However, every PV installation is unique. Thus, additional external UL/NEC AC and
DC surge protection and solid grounding practices are recommended.

A1-HYB series only supports a certain type of lithium-ion battery!
(Manufacturer certified battery)
CAUTION!
Risk of electric shock from energy stored in the capacitor. Never
operate on the inverter couplers, the Mains cables, battery cables, PV
cables when power is applied. After switching off the PV, battery and
Mains, always wait for 5 minutes to let the intermediate circuit
capacitors discharge before unplugging DC, battery plug and Msins
couplers.
CAUTION!
The unit contains capacitors that remain charged to a potentially
lethal voltage after the
, battery and supply have been
MAINS
PV
disconnected. Hazardous voltage will be present for up to 5 minutes
after disconnection from the power supply.
CAUTION!
When accessing the internal circuit of the inverter, it is very important
to wait 5 minutes before operating the power circuit or demounting
the electrolyte capacitors inside the device. Do not open the device
beforehand since the capacitors require time to sufficiently
discharge!
CAUTION!
CAUTION!
Possible damage to health as a result of the effects of radiation!
Do not stay closer than 7.87in/20cm to inverter for a long time.
CAUTION!
Danger of burn injuries due to hot enclosure parts!
During operation, the upper lid of the enclosure and the enclosure
body may become hot.
Only touch the lower enclosure lid during operation.
Authorized service personnel must use insulated tools when installing
or working with this equipment.
CAUTION!
NOTE!
The inverter is heavy. Use of lift equipment is recommended.
NOTE!
Make sure that existing wiring is in good condition and that wire is
not undersized.
NOTE!
Measure the voltage between terminals UDC+ and UDC- with a
multi-meter (impedance at least 1Mohm) to ensure that the device is
discharged before beginning work (35VDC) inside the device.
Keep away from flammable and explosive materials to avoid fire.
Do not install application in a corrosive environment where it may be
exposed to ammonia, corrosive gases, acids, or salts (eg: chemical
plant, fertilizer storage areas, tanneries, near volcanic ash eruption).
WARNING!
Never touch either the positive or negative pole of the
connecting
PV
device. Never touch both poles at the same time.
WARNING!
A1-HYB-G2 Series inverter should be coupled with a high voltage battery. The battery
must comply with UL 1973 and must be intrinsically safe.
As accumulator batteries may contain potential electric shock and short-circuit
current dangers, to avoid accidents that might be thus resulted, the following
warnings should be observed during battery replacement:
1: Do not wear watches, rings or similar metallic items.
2: Use insulated tools.
3: Put on rubber shoes and gloves.
4: Do not place metallic tools and similar metallic parts on the batteries.
5: Switch off loads connected to the batteries before dismantling battery
connection terminals.
6: Only personnel with proper expertise
carry out the maintenance of
should
accumulator batteries.
