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

3 phase AC voltage drawing details

Three phase: 380Vac/400Vac±10%(customized 190Vac/200VAC)

The three phase solar inverter of connection in actual picture

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 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!

PVMARS-BMS-system-for-battery
Heating, ventilation, and air conditioning (HVAC)

Heating optional, we will need to install other ventilation and air conditioning systems.

To dissipate heat generated by the lithium battery and PCS inside the BESS.

To avoid thermal runaway caused by the high temperature in the room, it will eventually result in a devastating explosion.

HVAC
Fire suppression system + Dynamic environment monitoring system

It is equivalent to adding a firewall, which is real-time video monitoring of all equipment inside the BESS.

For example HVAC, internal humidity (curve display), fire protection system, and intelligent control of BESS machine room access (providing security, anti-theft).

During 24-hour monitoring of multiple BESS operations, any abnormality will trigger an alarm, and technicians will be notified via dialing, SMS, email, and wireless modems.
