The Suntrio Plus 20K On-Grid 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.

Working 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 maximum AC apparent power of the Suntrio Plus 20K On-Grid Solar Inverter is—22000 VA.
  • The rated AC current from the solar inverter is up to 29 amperes.
  • The maximum generated AC current from the model—33 amperes.
  • The grid frequency range moves from—50 Hz, 60 Hz/44Hz-55Hz, 54Hz-65Hz.
  • The power factor of the model is 0.8 leading – 0.8 lagging.
  • THDi (total harmonic distortion) is less than even 3%.

Protective Features

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;

  • Internal Over-Voltage Protection
  • DC Insulation Monitoring
  • AC Short Circuit Current Protection
  • Thermal Protection
  • AC Surge Protection
  • DCI/GFCI/ Grid Monitoring

Frequently Asked Questions

Can I Leave my inverter on all the time?

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.

How fast does the inverter drain the battery?

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.

What does a solar inverter do?

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.

Can you charge a battery while using an inverter?

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.
