What is the application field of your products?
Our current Pmac series , with the flexible expansion ability and allocation capability, can be used in the small photovoltaic (PV) grid power generation systems of family units as well as the commercial photovoltaic system such as BIPV, BAPV and etc. GW10~17kw-DT Series, with the excellent performance, widely used in commercial photovoltaic systems and the constructions of photovoltaic power station.
What kinds of modules do your inventers support?
Our inventers support most of mainstream components and modules in the market. Should you require more details, please do not hesitate to contact our technical personnel.
How to choose the right inverters?
If you have chosen a specification model of solar modules and would like to select the most suitable photovoltaic inverters, please do not hesitate to contact us, and our technical support team will offer you useful advice. However, if you need the whole photovoltaic system solutions, you could also contact us. Our expert consultant teams will provide you with cost-effective solutions at the first time.
How in the stability of our inverters? What authentications we have got?
With ageing time over 12 hours, our inverters comply with the latest VDE-AR-N 4105 standard requirements. It’s MTBF trouble-free operation time is more than 100000 hours and Total Harmonic Distortion (THD) is less than 1% which is the best performance in comparison of the similar products. Moreover, our products have passed the authentication of CE, AS4777, AS3100, G83,and VDE; at the mean time, we are also applying for the authentication of CSA,FCC,ETL,CQC,ENEL Guide and RD1663.
How to correctly install your new inverters?
Please refer to the user manual, and only qualified technical workers are allowed to install these inventers.
Who will supply instant help in the event of a fault?
If a device becomes defective, you can contact the dealer, or directly contact GoodWe for door-to-door service by our technical personnel.
Who is eligible to disassemble and repair inverters?
The inventers can only be disassembled and repaired by professional and technical personnel authorized by Pilotpmac.
How to know the running state of your products?
You will be informed the running status through the inverter’s LCD screen and LED indicator.
Where can you find the serial number on your inverters?
You could find the serial number on the label of the right side of our products.
Why we need to measureharmonic?
Harmonic as noise in circuit, if it too much, will effect power quality to damage equipment reliability and life.We need to measure it, and then do some prevention according the Total Harmonic Distortion(THD).
Why the energy value not display or error display?
A: Check the meter whether or not with Energy function.
B: Check the CT and PT rate setting.
C: Check the CT and Voltage wiring, Stable, correct the Volt phase sequence and CT current polarity
D: Check the device reading mode.
NOTE: Voltage, Current, Power etc., parameter by same check method.
For Voltage measure line, How many Amp fuse we should use?
We need use PMAC770 on 3phase 3wire system, but the PMAC770 have neutral phase terminal? Are the PMAC770 only suit 4phase 3wire?
PMAC770 suit both 3phase 3wire and 4phase 3wire system. You can select the type in setting.
When you use 3phase 3wire, not need connect Neutral phase terminal.
Detail wiring please reference the drawing in use manual.
How about PMAC901 and PMAC903 energy meter’s starting current?
Direct connect mode: 0.1% Ib
CT connect mode: 0.4%In
