The SAJ 30K On-Grid Solar Inverter has an integrated maximum DC power input of 39600 Watts. The maximum DC voltage by the PV inverter is up to 1000 V. The voltage range of the MPPT module as input is from 180 – 900 V. On the other hand, the nominal DC range voltages are 600 V. The minimum DC voltage for suitable operativity is 180 V. The maximum. DC input current as per PV1/PV2 is 22/22/22.
The DC to AC conversion efficiency of the solar inverter is up to 98.8%. Likewise, the euro efficiency at 600 VDC is 98.5%. On the other hand, the accuracy given by each MPPT module is 99.5%. The rated output AC power of the model is 30000 VA. Likewise, the maximum AC apparent power generated can reach a highest of up to 33000 VA. The standard AC current integrated is 45.5 amperes—but the maximum reach of AC current is up to 50 amperes. On the other hand, the nominal AC voltage range of 3/N/PE, 220/380 V, 230/400V, 240/415V; 180V-280V/312V-485V.

The protective features of this model make it the best solar inverter in Pakistan—thus, allowing better use and ensured durability. These are;
As many of the ordinary inverters are reported to face damage due to over-voltage flow in the circuit. The internal over-voltage protection allows extended life expectancy of the solar inverter by protecting the circuit from the damage due to over-voltages flow.
The solar inverter connected to the grid requires to be monitored constantly as any problem in the system will be immediately notified to the user. thus, the solar inverter model is integrated with the grid monitoring to accomplish static outcome from the Grid Tariff.
In case of any AC short circuit, the SAJ 30K On-Grid Solar Inverter is integrated to shut off the flow of power through the circuit—this will prevent the system to face any relevant damage.
The overheating in electrical devices is a common cause that usually led to system failures. The solar inverter model has featured thermal protection so that in case of device being overheated, it tolerates efficiently. On the other hand, if the system gets heated over tolerated ratio—this feature is responsible of shutting down the power to protect from damage.
The solar power inverter is not limited to these protective features only—as Maxpower offers an extended durability, thus, it has;
For the DC connection to the solar inverter—the MC4/H4 port is intended in the model. on the other hand, for the terminal block is featured for the AC connection. It has integrated LCD display of 3.5 inches—the user can look the stats of currently working of solar inverter with Wi-Fi / GPRS and optional feature of ethernet.
