3 Phase Off Grid Inverter

Three phase off grid inverter convert DC power into three-phase power. A three-
phase power supply provides three alternating currents with evenly separated
phase angles. All three waves generated at the output have the same amplitude
and frequency, but vary slightly due to loading, while each wave is 120 degrees
out of phase with respect to each other.

Basically, a single 3-phase off grid is 3 single-phase inverters where each
inverter is phased 120 degrees apart and each single-phase inverter is
connected to one of the three load terminals

A three phase off grid solar inverter Advantages
The voltage of three-phase electricity is higher, which can drive high-power
electrical appliances, and is mostly used in industry.

Three-phase power can provide a better voltage level and is relatively safe.

The instantaneous power of the three-phase motor is a straight line, which is
equivalent to the average power and is relatively stable.

The efficiency of off grid 3 phase solar power transmission is much higher. At
the same cost, the power transmission capacity of three-phase power is stronger
than that of single-phase power.

Design Considerations for Installing an off grid 3 phase solar inverter
The selected battery voltage must be consistent with the DC input voltage of
the inverter.

The output power of the 3 phase off grid three phase battery storage inverter
must be greater than the power used by the electrical appliances, especially
for electrical appliances with high power at startup, a larger margin should be
left.

The positive and negative poles must be connected correctly. The diameter of
the connecting wire must be thick enough, and the length of the connecting wire
should be reduced as much as possible.

It should be placed in a ventilated and dry place, beware of rain, away from
flammable and explosive materials, and do not place or cover other items on the
machine.

Charging and power solar inverter cannot be carried out at the same time. That
is, the charging plug cannot be inserted into the electrical circuit of the
inverter output during inversion.

Before connecting the input and output of the machine, please ground the shell
of the machine correctly.
