Precautions
The safe operation of the product is subject to correct transportation, installation, operation,
and maintenance. Before conducting these tasks, please pay attention to relevant safety instructions.
The warnings related to safety in the manual are listed as follows:
Grounding Wire of Equipment
AC Value
DC Value
Phase
Before operating inverter, please read the instruction.
5minutes
In order to avoid electric shock, breack off machine with PV terminal and
AC terminal for at least 5 minutes, then contact the wire of machine output
terminal and input terminal
Warning: when machine works, the temperature of metal shell may be
very high.
u Procurement Inspection
Warning
1. If the inverter is found to suffer damage or lack in component and part, do not
install it, or else it may cause accident!
u Installation
Warning
1. In order to guarantee good effect of convection cooling, the inverter shall be
installed vertically. Keep at least 10cm space between upward side and downward
side.

2. Try to install it in the indoor place with ventilation opening or air interchanger. It is
forbidden to install it directly under sunshine.
3. During installation, do not discard residue of drill hole into inverter cooling find or
fan, which may affect heat dissipation.
u Wiring
Danger
1. The wiring shall be conducted by qualified electric technician, or it may cause
electric shock or fire disaster.
2. Before wiring, please confirm that the input power has been cut off, or else it may
cause electric shock or fire disaster.
3. The grounding terminal must be grounded reliably, or else the inverter shell may
have electricity.
4. The solar array, motor load, and inverter model selection shall be reasonable, or
else it may damage equipment.
Warning
1. Please use specified moment of force to tighten terminal, or else it may cause fire
disaster.
2. Do not connect capacitance or phase advance LC/RC noise filter in the output end
of inverter. When the distance between inverter and motor load is over 100m, it is
advised to use output reactor.
u Operation
Danger
1. Power on after confirming that the wiring is correct, or it may damage inverter or
fire disaster.
2. During electricity, do not change wiring, or else it may cause electric shock.

Operation Instruction of AQUAFLOW Series Solar Pumping Inverter Precautions
IV
Warning
1. Before the first operation, please adjust some control parameters according to
operation instruction. Do not alter the control parameters of inverter at random, or
else it may damage the equipment.
2. During operation, the temperature of radiator is very high. Do not touch the
radiator, or else it may scald you.
3. When height above sea level exceeds 1000m, the inverter shall be used under rated
power. If the height increases by 1500m, the output current shall decreases by 10%.
u Miscellaneous
Danger
1. Assign qualified electric technician for maintenance and inspection.
2. During power-up state, do not remove the inverter. After outage, wait for 5 minutes
at least, then conduct maintenance and inspection, so as to avoid that the residual
voltage on electrolytic capacitor of major loop may cause damage to people.
3. It is forbidden to transform the inverter without authorization, or else it may
damage personnel or equipment.
4. When handling scrapped inverter, please dispose the inverter as industrial waste.
The inner electrolytic capacitor may explode during burning. Some components and
parts may generate hazardous and harmful gas during combustion.

Chapter I Product Introduction
1.1 Introduction to Solar Pumping System
Solar Pumping System is widely applied in domestic water, agricultural irrigation, forestry
watering, desert control, grassland animal husbandry, island water supply, water treatment project,
etc. During recent years with the enhancement of new energy utilization, solar pumping system is
widely applied in the landscape and water spray system of municipal works, urban square, garden
sightseeing, tourist resort, hotel, and residential community. The system consists of solar cell array,
pumping inverter, and water pump(figure 1-1). Based on the design philosophy of saving water first,
the system omits energy storing device such as accumulator.
Figure 1-1 Structure of Solar Pumping System
The solar cell array is made from the series connection and parallel connection of several solar
cell modules, which absorb solar radiation energy and transform it into electric energy, so as to
supply electric power for the whole system. The pumping inverter controls and regulates the
operation of the system, transforms the direct current of solar cell array into alternating current to
drive water pump. In addition, according to the change of sunlight intensity, regulate output
frequency timely, to realize MPPT (Maximum Power Point Tracking). The water pump is driven by
three-phase AC motor. It pumps water from deep well, river, and lake, then inject water into water
storage tank/pool, or directly connect with irrigation system or fountain system, etc. According to
actual requirements of system and installation, different types of water pumps such as centrifugal
pump, axial flow pump, mixed-flow pump, or deep-well pump can be used.

check or control the running status and running mode of the system in a remote place.
u The design of AQUAFLOW solar pumping inverter selects electric supply or diesel
generator as standby inverter power supply, so as to meet the comprehensive requirements
of water supply.
u AQUAFLOW solar pumping inverter has complete operation protection mechanisms,
including output short circuit protection, IGBT module overcurrent protection,
acceleration/deceleration/constant speed overcurrent protection,
acceleration/deceleration/constant speed overvoltage protection, input

overvoltage/undervoltage protection, motor overload protection, inverter overload
protection, output side phase loss protection, inverter module overheat protection,
grounding short circuit protection, and underload (anti-dry pumping) protection.
u The main circuit uses power module (PIM), and the reliability is higher.
u The small-power model uses completely-new aluminum shell, LCD display operation
panel, and directly-insert connection terminal. The appearance is beautiful. The heat
dissipation effect and protective properties are good.
u Upper and lower water level detection and control circuit are optional.
u Protection grade IP65 (rated power is less than 22kW); temperature of service environment:
