The SAJ-R6-25KW is an on-grid three phase type inverter. This DC to AC inverter comes with a 5 years warranty. The working technology is smart as it has built-in independent RTC chip which supports data storage of about 25 years. The solar inverter model is safe, reliable as it comes with a surge protection system which guarantees system safety. Likewise, it has an anti-PID module that protects the solar panels from PID damage.
The output (AC) has the various ranges of voltages which are;
Coming up to the input (DC) ranges;
This solar panel inverter has the maximum efficiency capacity of 98.6% – the euro efficiency at 600VDC is 98.4%.
This inverter for solar systems comes with an AC short circuit protection system which will cut off the power automatically if any short circuit takes place. It gives thermal and internal over-voltage protection to the solar panel system which allows balance in the current voltage ranges.

This inverter works in a suitable temperature range from -25 to +60 degrees Celsius, with the humidity of 0 to 100%. The working altitude is about 3000 m which is less than 2000 m plus it is power derating. It comes with an intelligent fan cooling method which prevents overheating.
This inverter dimensions are 700 x 530 x 260 mm with a net weight of 48 kg. The specifications of this solar inverter include a 3.5-inch graphic LCD display which shows data in English language.
The inverters are basically known as power adapters, so they cannot store power in them. The solar inverters main work is to convert the DC power into AC power – also changes the voltage during this process.
Total 2 batteries of 12 volts are needed for a 5kW inverter which will have an input requirement of 24v DC. There are some models of inverter which come in a 48V DC system, that require four 12 volt batteries.
Solar panel systems do not really need maintenance in their lifetime and they can work for about 25 to 28 years or more. If something wrong happens to the parts of the inverter then they have a warranty through which you can replace the parts without spending money on it.
