Inverter for Solar Panel System

700 watt to 6000 watt off grid inverter system

Tips: Can single-phase inverter and three-phase inverter be connected?

A customer who has installed a three-phase 15kW inverter. Recently, 10pcs of 300W components will be added. If he wants to use a single-phase inverter, is it possible to connect the electric system?

1. There is no problem with zero-line system access

According to the current national standard "Design Code for Low Voltage Distribution" (GB50054), there are three grounding modes of low voltage distribution system, namely IT system, TT system and TN system. Among them, IT system has no zero line, TT system and TN system have zero line, and most of them are TN system in industrial, commercial and civil systems. On grid inverters are connected to the grid. Three-phase inverters are three firing lines, one zero line and one ground wire. Single-phase inverters are one firing line, one zero line and one ground wire. If there is a three-phase grid, single-phase inverters can only connect one phase line (that is, the firing line) and one ground wire with one zero line, so there is no electrical problem.

2. It's no problem to use three-phase four-wire meter to measure electricity

Three-phase watt-hour meter is used to measure the power output (or load consumption) of three-phase AC circuit. Its working principle is exactly the same as that of single-phase watt-hour meter. It only adopts the way of multi-group driving parts and multiple aluminum discs fixed on the rotating axle to realize the measurement of three-phase electric energy. Three-phase four-wire active watt-hour meter differs from single-phase watt-hour meter in that it consists of three driving elements and three aluminum discs mounted on the same rotating shaft. Its reading directly reflects the energy consumed by three-phase watt-hour meter. Three phases are measured separately, allowing three phases to be different, so the power of one phase increases without affecting the other two phases.

3. Matters needing attention

When single-phase inverters are connected to the power grid, we should pay attention to two problems. One is the unbalanced three-phase. Therefore, we should try to connect single-phase inverters to the phase with the greatest load. If the three-phase load is balanced, the single-phase power should not be too large, and it is better not to exceed the load power. If the photovoltaic power is larger than the load power, when the photovoltaic system is connected to the grid, if the local load cannot be consumed, it will be sent to the remote load or the upper power grid, which will cause the voltage of the inverters to rise. The higher the power is sent out, the higher the voltage will be. Seriously, it may cause the overvoltage protection of the inverters and shutdown.

Works great
I'll start by saying this 3000w off grid isolar nverter actually does work as advertised. I was able to run an air compressor and other high usage appliances without issue. Highly recommend!

Powerful off-grid inverter
After choosing for a long time, I was still defeated by the texture and appearance of this inverter. It is really beautiful, and the workmanship is good. It can drive anything without picking an electrical appliance; the kettle, hair dryer, power amplifier, etc. are not like other brands. Power comes standard, it is recommended to buy this.

Great! Just what I wanted.
This off grid inverter is perfect so far using my 48V system. It more than met my expectations so far. I don’t have a problem with that, just have the battery power and it will run continuous. I couldn’t be more pleased.
