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.

DC Voltage Single-Phase AC Voltage

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
Single-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.

Chapter IV: Failure Diagnosis

4.1 Explanation and Solution for Fault Code

BS series solar pumping inverter has complete protection. When system suffers failure, the
inverter will take protective measures: the general protective measures are to stop the output of
drive signal of motor and forbid to re-start within a certain period.

When failure or protection happens, the failure or protection needs to reset the inverter. Power
off input power supply, then power on it. If the failure is not still settled, please contact with
manufacturer to settle it.

The common failures are listed as follows:

 Chapter V Maintenance

5.1 Daily Inspection and Maintenance

Affected by environment temperature, humidity, vibration, and inverter internal component
aging, the inverter may suffer some potential problems during operation. In order to stably operate
the inverter for a long term, conduct periodical inspection once each year.
5.1.1 Requirements of Inspection and Maintenance
1. The inspection shall be conducted by professional technician. When necessary, cut off the
power supply of inverter.
2. Avoid leaving metal components and parts in inverter, or else it may damage the equipment.
3. The inverter has conducted electrical insulation experiment before leaving factory, so the
user needn’t conduct high-voltage insulation test.
4. If you intend to conduct insulation test on inverter, all input and output terminals must be
short circuit reliably. It is forbidden to conduct insulation test on single terminate. Please
use 500V megameter during test.
5. It is forbidden to use megameter to measure control loop.
6. When conducting insulation test on motor, remove the connecting line between motor and
inverter.
5.1.2 Key Points of Inspection and Maintenance
Please use the inverter under the environment recommended in the manual and conduct
inspection and maintenance according to the following table.

5.2 Inspection and Replacement of Quick-wear Parts
5.2.1 Filter Capacitor
The pulsating current of main loop will affect the performance of filter capacitor of aluminium
electrolysis. The affected degree and environment temperature are related to service environment.
Under normal conditions, the inverter shall change electrolytic capacitor once every 10 years. When
electrolyte of electrolytic capacitor leaks, safety valve emits, or capacitance expands, replace it
immediately.
5.2.2 Fax cooling
In BS series pumping inverter, the inverter above BS-22K has cooling fan inside. The service
life of cooling fan is about 15000 hours. If fan has abnormal nose or generates vibration, replace it
immediately.

5.3.1 Storage
After purchasing inverter, if you do not use it temporarily or decide to store it for a long time,
pay attention to the following items:
1. Avoid putting inverter on the places in which temperature is high, air is humid, or places
where there is vibration or metal dust. Guarantee good ventilation.
2. If the inverter is not used for a long term, the internal filter capacitor characteristic will
decrease. Power on twice every two years to recover the characteristics of filter capacitor.
At the same time, check the functions of inverter. During power-on, gradually increase the
voltage through DC power supply. The power-on time shall not be less than 5 hours.
