A1 Hybrid 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.
Battery Safety Instructions
►
A1 Hybrid Series inverter should be coupled with a high voltage battery.
The battery must comply with UL 1973 and must be intrinsically safe.
For the specific parameters such as battery type, nominal voltage and nominal
capacity etc., refer to Section
4.3.
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 should carry out the maintenance of
accumulator batteries.

2.2 Explanation of Symbols
This section gives an explanation of all the symbols shown on the inverter and on
the type label.
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.
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!
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.

Battery Status.
Danger to life due to high voltage.
There is residual voltage existing in the inverter after powering off
which needs 5 minutes to discharge.
Wait 5 minutes before opening the upper lid or the DC lid.
Warning!
When a ground fault is indicated, normally grounded conductors
may be ungrounded and energized or normally ungrounded
conductors may be grounded.
