PVMARS solar Factory -100% Lab

100% EL TESTING, 100% IV TESTING, 100% DIGITAL WORKSHOP

In strict accordance with the German 5S technical standard, our production workshop has marked the production time, model, quantity, and other information for each raw material. Successfully ensure the high quality and efficiency of finished products.

Global authoritative certification

PVMARS solar products have passed TUV, IEC, ISO, CE, and RoHS quality certifications.

Before leaving the factory, our testers will perform no less than 120 extreme impact tests, and all kinds of inspections in order to get your approval.

Safety reminder for solar system

With PVMARS solar IoT, through your phone or computer view real-time performance data of your solar system, such as solar panel power generation, battery capacity, etc., and receive timely maintenance and safety alerts to extend the life of your solar system.

At the same time, your dedicated engineers will help you adjust the data through IOT. Double protection!

Can power supply 220v and 380v devices at the same time?

As the name implies, 3 phase AC voltage has at least three fire lines, and in these three fire lines in physics, we simply give different characters (there may be some differences between different countries, but generally defined as R, S, T).

R+ S + T = 380V or 400V (±5%-10% floating, can be customized for special voltages 180Vac/200Vac, etc.)

If you also have a 220v device, it is usually achieved by a zero line, and in logistics, we assign the character N

R+ N = 220v, S + N = 220v, T + N = 220v

We can use both three-phase and single-phase devices together in one Three-phase solar power system

For most 220VAC appliances, the voltage is single-phase. Such as air conditioners, fan, light, TV, and so on.

For most 380VAC-450VAC appliances, the voltage is three-phase. Such as motors, power pumps, central air conditioning, industrial equipment, and so on.

Your dedicated engineers are ready to start customizing your solar clean energy system!
