Sununo plus 5K-M consists of an on-grid type inverter and comes in single-phase, thus, considered as a suitable solar inverter model for home. This inverter is mainly used in PV grid-connected systems so that it converts DC power into AC, which will be used in residential electrical equipment. This solar inverter price in Pakistan is 214,500 rupees; there are also different solar inverter price-lists for variants having different power ratios.
Some of the important features these inverter offers are;
The consumption of this inverter at night is greater than 2W, at standby its 6 watts. The temperature range required to operate this inverter is -25 degrees Celsius to +60 degrees Celsius. The non-condensing ambient humidity of this model is 0 to 100% and an altitude of up to 2000 m comes without power derating.
The dimensions of this inverter are 454 x 355 x 150 inches. Net weight is about 14.8 kg. This model is considered the best solar inverter 2021 because of its convenient installation. It is small, light in weight, and transform-less. The Sununo Plus 5K-M On-Grid Solar Inverter comes with a special mounting design which makes it easy to install. Real panel types mounting systems are used in this On-grid single-phase solar inverter.
The accessed DC power this inverter gives is 6050 watts. The input (DC) voltage range of this model is;
Coming up to the output (AC) ranges;
The frequency range, this inverter gives is about 50 to 60 Hz. It consists of an adjustable power factor of 0.9 leading or lagging. This model gives the THDi (total harmonic distortion) at nominal power is greater than 3%.
If you are leaving your inverter on, that means it’s using continuous AC (alternate current) power. This will not change any of your settings like clock settings, etc. on devices. You can also leave the solar inverter on while you are on a trip if you want to charge your devices or want them to keep working.
Yes, an inverter can still use a bit of power if no appliances or devices are plugged in with it. If you connected the inverter with your car’s battery and let it stay on, then it will surely use about 10 percent of the inverter’s power.
The charging time of the inverter’s battery is dependent on the battery’s size like small batteries take the time up to 12 to 16 hours and large ones take about 36 to 48 hours. The charging time of a battery can be reduced by using various stage charge methods or higher charge currents.
