The Sofar Three Phase Dual MPPT Solar Inverter has recommended a maximum power range from photovoltaic input of 19950 Wp. The maximum DC (direct current) power for a single MPPT module is ranged to 11000W/7500W. The DC inserts are 2/1 and the number of trackers (MPP) is two. The Sofar Solar Inverter can intake a maximum voltage of 1K V. On the other hand, the voltage required for smooth starting up is 200 V.

  • The recommended input ratio of voltages—600 V.
  • MPPT operating voltage range is from 160 to 960 V.
  • On the full potential, the MPPT module has a voltage range of 500 to 850 V.
  • The input current range of solar inverter MPPT is 21A/11A.

The short maximum DC input short circuit current per MPPT module delivered ranges from 30/15 Amperes.

Working Efficiency

The Sofar three-phase dual MPPT PV inverter is considered the best solar inverter in 2021 because of delivering a robust efficiency of 98.3%–that is way more than any of the competing models in the industry. The scaling of working efficiency over the European weighted measurement is likewise 98.0%. The solar inverter has a power self-power consumption of below one watt (when no production is in the process—night time). It pushes off an active power-adjustable range from 0~100%.

AC Power Conversion

The solar inverters give off a rated AC power of 15K watts. At the fullest potential, the ratio uplifts to 16500 Watts. The current produced-off with end ratio is merely 3*24 amperes. The voltage inverter has a nominal grid voltage of 3/N/PE, 220/380Vac, 230/400Vac, and 240/415Vac. On the other side, according to the local standard, the grid voltage range is 310 to 480 Vac while having a frequency range of 45-55/54-66 Hz.

Protective Features

The Sofar Solar Inverters are known for their robust grid-tied, and hybrid ranges—but much far, they are appreciable for their noticeable efficiency and protective features.

  • DC Reverse Polarity Protection: The model has DC reverse polarity protection enabled that ensures no damage to the device even if the power supply polarity gets reversed. This is because, it cuts off the power to the electronic circuits in the transmitter and transducer, if the DC polarity is reversed.
  • Safety Protection: The Sofar solar inverters monitor and ping out if there is any anti-islanding, RCMU, or grounding fault.
  • ARPC: In some of the models (optional), the anti-reverse power controller makes sure that solar energy is supplied to the load, by monitoring the voltage and current consumed by the user.


The Sofar power inverter for home or commercial use has an ambient temperature range from -25 to 60° C. The working constituent is based transformerless. The relative humidity range for optimal working is 0~100%. The DC to AC inverter can withstand a maximum operating altitude of 2000m. Although, the given noise range is ≤45dB. Likewise, Max power provides the best solar inverters in Pakistan, here are other efficient models for residential to commercial use; Solar inverters.

Physical Stats

It is a bit heavier than the normal residential inverters but lighter in this power range—55 lbs. (25 kgs). The sofar DC inverter has installed cooling fans to keep a proper airflow and prevent overheating even at the time of longest working. The LCD display is integrated that gives off the operativity status of voltages, power conversion efficiency, any error (if prominent), connectivity, etc.
