BPD Series PV Pumping Inverter

BPD series PV pumping inverter Preface
-i-
Preface
BPD series photovoltaic (PV) pumping inverters are developed for outdoor PV power
supply of water pumps based on the core control algorithm of Goodrive series
high-performance inverters and the requirements of PV pumping application and control.
They provide multiple control and protection functions, such as tracking the maximum
power, hibernating at weak light, waking up at strong light, hibernating at high
water-level, and underload protection. The PV power supply can be automatically
switched to grid power supply as required by customers to ensure the proper operation
of the water pumps.
See the commissioning guide in this manual when performing commissioning on the
inverter.
If the product is ultimately used for military affairs or manufacture of weapon, it will be
listed on the export control formulated by Foreign Trade Law of the People's Republic
of China. Rigorous review and necessary export formalities are needed when they are
exported.
Our company reserves the right to update the information of our products without prior
notice.

1.3 Safety guidelines
Only qualified electricians are allowed to operate the inverter.
Do not carry out any wiring or inspection or change components when the
power supply is applied. Ensure that all the input power supplies are
disconnected before wiring and checking, and always wait at least the time
designated on the inverter or until the DC bus voltage is lower than 36 V.
The following table describes the waiting time.
Inverter model
Min. waiting time
220 V
0.75 kW–4 kW
5 minutes
380 V
2.2 kW–5.5 kW
5 minutes
Do not refit the inverter unauthorizedly. Otherwise, fire, electric shocks, or
other injury may be caused.
The base of the radiator may become hot when the device is running. Do
not touch it. Otherwise, you may get burnt.
The electrical parts and components inside the inverter are electrostatic.
Take measurements to avoid electrostatic discharge when performing
operation involved with them.
1.3.1 Delivery and installation
Install the inverter on noncombustibles and keep the inverter away from
inflammables.
Do not operate the inverter when it is damaged or any of its components
are lost.
Do not touch the inverter with wet items or body. Otherwise, electric
shocks may occur.
Note:
Use proper handling and installation tools to avoid damage to the device or
physical injury. Installers must take mechanical protective measures, such as
wearing anti-smashing shoes and working uniforms, to protect personal safety.
Do not carry the inverter by its cover. The cover may fall off.
Do not open the cover plates of the inverter. Only professional technicians are

BPD series PV pumping inverter Safety Precautions
3
allowed to perform such operation.
Ensure that no physical impact or vibration occurs on the product during its
transport and installation.
Install the product in a place that will prevent children or other people from touching
it.
The leakage current of the product may be larger than 3.5 mA during operation.
Perform reliable grounding and ensure that the grounding resistance is lower than
10 Ω. The conductivity of PE grounding conductor is the same as that of the phase
conductor (with the same cross sectional area).
DC INPUT is the PV input terminal, AC INPUT is the power input terminal, andAC
OUTPUT is the motor output terminal. Connect the input power cable and motor
cable properly. Otherwise, damage to the inverter may be caused.
Before connecting the 1PH AC grid cable to the inverter, take protection measures
such as the lightning protection and short circuit protection according to the local
electrical safety standard.
The distance between the DC output line of the PV panel and the DC terminal of
the inverter cannot exceed 10 meters. Otherwise, measures need to be taken to
prevent overvoltage.
1.3.2 Commissioning and running
Before performing terminal wiring, disconnect all the power supplies of
the inverter and wait at least 5 minutes.
The voltage inside the inverter is high when it is running. Do not perform
any operation except keypad-based setting.
The inverter may automatically start when P01.21=1. Do not get close to
the inverter and motor.
The inverter cannot be used as an "Emergency-stop device".
Note:
Do not switch on/off the input power supply of the inverter frequently.
For inverters that have been stored for a long time, check it, adjust the capacitance
and perform a test run before using it.
Cover the front cover plate before the running of the inverter. Otherwise, electric

shocks may be caused.
1.3.3 Maintenance and replacement of components
Only qualified electricians are allowed to perform the maintenance,
inspection, and component replacement on the inverter.
Before performing terminal wiring, disconnect all the power supplies of
the inverter and wait at least 5 minutes.
Take measures to prevent screws, cables and other conductive matters
from falling into the inverter during maintenance and component
replacement.
Note:
Use proper torque to tighten screws.
Keep the inverter, parts, and components away from inflammables during
maintenance and component replacement.
Do not carry out any isolation and voltage withstanding test on the inverter, and do
not measure the control circuit of the inverter by megameter.
1.3.4 Waste disposition
There is heavy metal in the product. Deal with it as industrial waste.
When the life cycle ends, the product should enter the recycling system.
Dispose of it separately at an appropriate collection point instead of
placing it in the normal waste stream.

2.5.3 Instruction of power terminals
1. ①is an AC input terminal and the model supporting mains input provides this terminal.
(Note: For safety, ensure that PE is properly connected.)
2. ⑥is an AC output terminal connected to the water pump motor. When using a 3PH
motor, connect U, V and W of the motor to U, V and W of the inverter, and connect the
motor enclosure to PE of ⑥.
3. The wiring varies with control modes if a 1PH motor is used:
(1) 1PH control: Connect the motor phase line to U and W of inverter terminal ⑥,
connect the motor enclosure to the PE pin. There is no need to remove the starting
capacitor and the wiring is easy. But the starting performance is not as good as that in
2PH control mode, so this wiring mode is applicable only to some motors.
(2) 2PH control: It is necessary to remove the starting capacitor and operation capacitor

(if any). The wiring of a general motor is shown in Figure 2.3: L1 is the running winding,
L2 is the starting winding, C1 is the running capacitor, C2 is the starting capacitor, and
when the motor speed exceeds 75% of the rated speed, the starting capacitor is
switched off through the centrifugal switch K.
