With modular design and IP65 protection, VEICHI SI30 synchronous photovoltaic pump inverter is highly praised by customers. Compared with SI20, the SI30 series inverter enhances the overall performances both in hardware and software. SI30 Video: https://youtu.be/eS5JCRXyUcI
Solar pump IOT system
Real-time monitoring, remote expert consultation, large data automatic calculation of energy-saving status and support PC and mobile APP query.
IP65---360 degrees waterproof and dustproof
SI30 adopts specialized die-casting aluminum Ai-Si-Cu alloy as the shell material, with the high-end protection of IP65: waterproof panel, waterproof joint and waterproof enclosure.
AC/DC automatic switch
Basing on the customers’ requirements, the AC and DC power supply could be automatically switched by software.
There are complete and enhanced protections in SI30, such as the dry run, dormancy, water fulfill, phase failure, OC, OV, OL, OH and so on.
AM and PMSM Motors
Same as SI20, the SI30 series solar pump inverter could perfectly work with AM and PMSM motors.
Bluetooth keyboard is firstly adopted in SI30 series by scanning the code to meet the on-site requirements. In addition, there is also external keyboard which is available for customers.
One Key Start and Stop
The human computer interface in the pre-cover support end users "one key start and stop".
