Above is the PVMars inverter production video.
We always follow the German 5S technical standard, and our 7s production management system:
1- Raw Materials Supply System
Our attitude towards raw materials is that we would rather spend money and time purchasing different brands on a large scale for testing, rather than sacrifice users’ trust in us and take the risk of using raw material suppliers that have not been tested.
Through our testing and application over the years, here are the brands we often work with:
MCUs come from well-known brands such as TI, NXP, ST, Microchip, Infineon, and Renesas.
MOSFETs are from American brands such as Infineon/IR.
2- Production System:
We use an automatic machine plug-in for the PCB plate of the inverter to improve efficiency, reduce loss, avoid manual errors, and strengthen stability.
3- QC System:
AOI equipment and ICT are used to detect the state of each PCB board, whether there are cracks, pinholes are aimed at the PCB board, all lines are checked, and the failure rate is reduced.
The PCB board with problems is automatically summarized into the wrong box, and the PCB board with passed quality will be installed in the next round of accessories.
In addition, our production department will prevent AOI equipment omission. Manual spot checks are also conducted to ensure quality.
4- Factory Inspection System:
We generally use no less than 100 times the limit failure test.
Through user feedback statistics, 100% of the tested machines can work stably
5- Packaging System:
All our packaging and products are OEM customized and can be silk screen printed or stickers exclusive to your company logo.
Plywood wooden box packaging, containing pearl cotton. One piece in one package.
MW-level projects will be transported in ESS containers, and the interior will be upgraded and reinforced. We will have professional engineers ready to answer your questions about MW-level solar energy storage systems.
6- After Sales Service System:
Different from batteries, there are different PCB boards inside the inverter.
We have corresponding maintenance mechanisms for different PCB boards.
Within 2 years of warranty scope, after IOT data or online remote detection, you can find which PCB has a problem.
We will send the corresponding replacement of a new PCB board or more spare parts for free, and PVMARS has operation videos to replace different inverter parts so that you do not have to worry about maintenance problems.
