Quick Overview
Industrial and Commercial three phase PV grid-connected inverters are mainly used in commercial rooftop PV grid system, to turn PV DC current into AC current for equipment in factories or sell to power grid. Suntrio Plus 12-20K is characterized with high efficiency, convenience in installing, stable and reliable. It’s preferred inverter for commercial PV investment.

The SAJ-R6-20KW Grid Tied Inverter 2MPPT Three-Phase Solar Inverter comes with a warranty of up to 5 years. This solar inverter model is considered super-efficient as the DC to AC conversion ratio is merely up to the mark. The recommended accessed DC power is up to 24200 Watts. Likewise, the solar inverter MPPT module is able to handle a maximum DC voltage range of 180 – 900 V. The voltage required for the starting of the solar power inverter model is up to 200 V. On the other hand, the minimum DC voltage as the input is 180 V. There are two MPPT modules installed in the solar inverter for better conversion efficiency.
The maximum efficiency of DC to AC conversion is up to 98.5%—the MPPT module has an accuracy of >99%. The rated AC power generated out by the solar inverter model is up the 20000 VA. Here, are some of the important outputs working factors;

The protective features of the solar inverter allow the device to be safe from imminent damage—this can be because of many reasons. Some of the protective features are;
This might be important when you are not leaving the place—keeping the solar inverter turned on all the time does not get to lose the AC power, thus, the appliance won’t lose any certain settings. In case, if the user is leaving the place, then he/she must turn off the solar inverter.
The solar inverter without any load or appliances to operate—usually consume 0.1 – 0.2 amperes per hour. On the other hand, the larger models consume 2.0 ampere per hour.
As the solar plates capture the sunlight and generated energy in the form of DC power—but the standard home appliances are required AC power to be operated properly. This is where solar inverters bump in. They take in the DC power generated by the PV plates and invert them to the AC form.
Using any of the best solar inverters to charge the solar batteries is considered safe for usage—as the simple solar chargers for the batteries are likewise a good option for them but solar inverters being connected for too much might cause any damage.
