2.5 Capacitor discharge
The unit contains capacitors that remain charged to a
potentially lethal vo ltage after the MAI NS and PV supply has
been disconnected.
RISK OF ELECTRIC SHCOK!
Hazardous voltage present for up to 40 minutes after disconnection
Powfuture Science &Technology Co., Ltd
User Manual V2.0 11
from power supply.
CAUTION – Risk of electric shock from energy stored in
capacitor, never work on the solar inverter couplers, the MAINS
cable, PV cables or the PV gene rator when power is applied.
After switching off the PV power and mains, always wait for 15
min to let the inte rme diate c ircuit cap acitor s dischar ge bef ore
you unplug DC input and MAINS couplers, when access to
internal circuit of solar inverter, It is very important to wait 40
minutes before working on power circuit or demounting the
electrolyte capacitors inside the device. Do not open the device
before hand since the capacitors require this long to discharge
sufficiently!
Measure the voltage between terminals UDC+ and UDC with a
multimeter (impedance at le ast 1 Mohm) to ensur e that t he de vice i s
discharged before beginning work (35VDC) inside the device.
This waiting period can be reduced by shorting the input terminals with
a 10 Ohm/10 W resis tor.
If the device is failed to discharge, do not use, call manufacturer.
Only trained and authorized professional personnel were allowed to
perform, installation, servicing and maintenance works.
The unit stop functi on does not r emove dange rous vol tages from the
unit, cut off the MIANS and PV input supply to the end use equipment
incorporating the unit.
The capacitors may fail to discharge, or be prevented from being
discharged by a voltage applied to the output terminals. If the unit has
failed in a manner that causes the display to go blank immediately, it is
possible the capacitors will not be discharged. In this case, consult
POWFUTURE or their authorized distributor.
WARNING! Do not work on the s olar inverter when the device
is running.
Never touch either the positive or negative pole of PV
connecting device. And never ever touch both at the same
time!
2.6 PE connection and leakage current

(RCD) with rated fau lt cur r e nt Ifn ≤ 30mA which automatically
disconnects the device in the case of a fault.
DC differential currents are created (caused by the insulation
resistance and through capacities of the PV generator). In order to
prevent unwanted triggering during operation, the rated residual
current of the RCD has to be min. 30mA。
The device is intended to connect to a PV generator with a capacitance
limit of approx. 300 nF
HIGH LEAKAGE CURRENT! EARTH CONNECTION ESSENTIAL
BEFORE CONNECTING SUPPLY.
Incorrect grounding can cause physical injury, death or
equipment malfunction and increase electromagnetic interference.
Make sure that grounding conductors are adequately sized as required
by safety regulations.
Do not connect the ground te rmina ls of the unit i n ser ies in case o f a
multiple installation.
This product can cause current with a d.c. component. Where a
residual current to operated protective (RCD) or monitoring (RCM)
device is used for p r o te c tion in c a se o f dir e c t or indirect contact, o nly
an RCD or RCM of Type B is allowed on the supply side of this product.
2.7 Safety Check
The following safety checks should be performed at least every 12
months by manufacturer’s qualified person who has adequate training,
knowledge, and practical experience to perform these tests. The data
should be recorded in an equipment log. If the device is not functioning
properly or fails any of tests, the device has to be repaired.
1. Inspect the equipment and accessories for mechanical and
functional damage.
2. Inspect the safety relevant labels for legibility.
3. Inspect the fuse to verify compliance with rated current and
breaking characteristics.
4. Verify that the device functions properly as described in the
instructions for use.
5. Verify that the current/voltage sensors functions properly.
Powfuture Science &Technology Co., Ltd
User Manual V2.0 13
6. Verify software or firmware that performs safety critical application
functions properly.
7. Check earth connection, retightening of terminals.
8. Check interface protection and inverter setpoints functions
properly. Refer to section” Interface protection and Inverter set
points;
9. Measurement of insulation resistance, consult manufacturer.
10. Measurement of earth resistance, consult manufacturer.
11. Mounting structures: Verify tightness and integrity of bolts and
other fastening devices; Verify if there is significant corrosion.
12. Using manufacturer’s procedures and/or technical data on an
“as-needed” basis when performing periodic component
calibrations.

VOLTAGE power generation device, the installation
must be performed by qualified personnel only in
compliance with national and local standards and
regulations.
Installed to be clear of obstruction. The enclosure must never be
covered.
The equipment is classed as one not accessible to the general public.
A suitable guarding which is keep min. 1.5mm distance around the
perimeter of the device is mandatory to prevent against access to
general public, especially for children or infirm persons when the
device is located in an unprotected area.
Make sure that dust from drilling does not enter the unit when
installing.
Do not place flammable materials near the unit. Failure to observe this
warning may result in a fire.
3.6 Mounting Sequence
1. Read the manual, pay special attention to the section on safety.
2. Install the inverter according to 《Installation Guide》.
3. Turn on PV by turning the DC switch on.
4. The inverter is now ready for operation.

User Manual V2.0 21
The unit shall be installed in accordance with national wiring
regulations. Compliance with safety regulations depends upon
installing and configuring system correctly, including using the
specified wirings . The system must be ins talled only by pro fessional
assemblers who are familiar with requirements for safety and EMC.
The assembler is responsible for ensuring that the end system
complies with all the relevant laws in the country where it is to be used.
The individual sub-assembly of the system shall be interconnected by
means of the wiring methods outlined in national/international
regulations such a s the Natio na l Ele ctric Co de (NFPA ) No . 7 0. o r VDE
regulation 0107.
Power to the unit must be turned on only after installat ion work has
been completed. All electrical connections must be carried out by
qualified personnel in accordance with legislation in force in the
country concerned.
Before connecting, disconnect the connection between solar
generator and inverter and locked it to the open position during
installation. Place a warning sign “do not turn on – maintenance
in progress” on the external disconnecting switch when it is
shut down, and make sure that on-off remote controls are
inhibited. Refer to this manual, section 3.Safety instruction and
EC Directives – isolation device.
The open-circuit voltage of PV generator under worst case
conditions of ambient temperature, irradiance, etc. shall never
not exceed 500V, failure to observe this, it may cause elctric
shock hazards or completely damage of the inverter.
WARNING: HIGH LEAKAGE CURRENT, EARTH CONNECTION
ESSENTIAL BEFORE CONNECTING SUPPLY.
For the cables connected to PV inverter and Grid, choose the
appropriate wires according to the capacity of the inverter and PV
components.Calculate the max. input current and max. output current
of The inverter according to the actually system , inverter rating Label

“Grid volt. Fault”
The gird voltage has exceeded the
permitted range according to local

• Check the grid voltage.
• Check the grid connection
of the inverter.
If the grid voltage exceeds the
permitted range because of
local grid conditions, pl ease ask
the utility operator if the
voltage can be adjusted at the
feed-in point or if changes in
the values of the monitored
operational limits are possible.
If the grid vol tage tha t checke d

“Grid volt. 10min Fault”
The average gird voltage over 10
minutes has been outside the

Following causes might lead to
error 0 or error 1:
• Grid volt
age is too high at the
point of common coupling to the
inverter.
• Grid impedance a t t he ter mi nal
of the inverter is too high.
For safety consideration, the
inverter will disconnect itself from
the grid for a short period of time,
and it will reconnect to th

“Grid Frequency Fault”
The grid frequency has left the

For safety consideration, the
inverter will disconnect itself from
the grid f or a short period of time,
and it will reconnect to the grid
