Solar water pump controller inverter 11kw 15kw for solar pump system
MPPT introduction MPPT means Maximum Power Point Tracking; it’s a special function for solar system, which is used to get the maximum possible power from one or more photovoltaic devices, typically solar panels. Solar panels have a complex relationship between solar irradiation, temperature and total resistance that produces a nonlinear output efficiency which can be analyzed based on the I-V curve. It is the purpose of the MPPT system to sample the output of the cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions.
By adopting this technology in the solar pump inverter, it increases the working efficiency of solar panels, and also adjusts the output frequency of solar pump VFD based on the sunshine strength; make sure the system always works at an optimum condition.
Electrical Specifications and Power degree
Noted: We suggest solar panel power should be 1.3-1.4 times higher than solar pump power , And solar pump inverter power should be higher level than solar pump. When solar pump distance to inverter higher than 100m, It should be equipped with Output reactor or higher level power inverter. For Solar panel,total VOC less than Maximum DC voltage of inverter and Solar panel vmp is recommend 530V for 380V pump and 305V for 220V pump.
VEIKONG VFD500-PV solar pump inverter Features:
1. Cover voltage levels 220V AC and 380V AC. Support single-phase 220V and three-phase 220V/380V pumps,the power from 0.4KW to 37KW.
2. Easy to use The inverters automatically start or sleep only after being connected to solar battery panels without any parameter setting.
3. Highly reliable for using multiple protective measures Including PV over-voltage protection,PV polarity reverse warning,and auto derating against over-temperture,which extend product life.
4. Use advanced MPPT algorithms,ensuring that the solar power tracking efficiency reaches 99%
5. Models of 2.2kW or lower can be configured with boost module,meeting low-voltage work requirements.This reduces the use of solar battery panels and therefore the cost.
6. it can implement auto switch between solar input and grid input by configuring the boost or auto switching cabinet(meeting lightning protection requirements),implementing 24-hour unattended work.
Product Application Quality Control VEIKONG solar pump VFDs have passed comprehensive test process
during manufacturing.
R&D test: test the hardware and software performance, to make the design more optimization, makes sure the products have excellent performance before production;
Board test: test the performance of every board in our products, to reduce product defective rate; IQC: take strict quality inspection for every income components, to ensure every income components are qualified.
Aging test: make the solar pump VFDs at run status, put them in the aging test house at 50°C for 48 hours, to remove every unqualified products.
Load test: the last and the most important test, add different load to the solar pump VFDs, test their input and output value, to check their working performance. unqualified products will be removed from the team. By applying such strict testing process, VEIKONG ensures every outgoing solar pump VFD has excellent quality. FAQ 1. How to achieve Automatic start after stop? If it is controlled by keyboard no need to set any parameter. If
you want to control by external switch As the default control mode is keypad control, First set P00.06=1
and use a wire or switch to connect com and DI1,When the switch is closed, the drive run, when the switch is open,
the drive stop 2. How to design solar PV water pump system? Key point: the rated VOC and VMP and power of the PV Array need to
match the input range of the inverter. If needed, we will provide technical support online. 3. How to use a float in the water tank to stop the pump if the
tank is full? If your float signal is digital signal Use float switch to short DI
3 and com ,see diagram 1.3 4. How to set minimum frequency ( for example) 30hz and maximum 50HZ Set P47.05=30HZ and 47.06 to some time and 47.07 to some time.
Please refer to details of P47.05-47.07 5. If pump is 60HZ frequency, how to set max frequency? Notice: If your motor rated frequency is 60HZ First solution for
you, P01.06=P01.08=P11.05=60HZ. Quick setting and easier way: you should set P00.11=02 If your
motor is three phase; if your motor is single phase with capacitor ,set P00.11=22;If your motor is single phase
without capacitor ,set P00.11=32 6. How to make the water pump system work without sunshine? Usually, solar PV water pump system can meet the needs of pumping
water.
7. How to check and solve basic problem of inverter trips and error a:Check the total vmp and voc of solar panels ,solar panel
technical data b:Check motor pump power and rated current c: Check the distance between motor and inverter d: Check trip record r25.00 r25.01 25.02 25.03 r26.00 r26.01 r26.02
r26.03 e: Check troubleshooting fault and find relevant solutions f : Check if motor insulation has been damaged or motor is blocked
