Ease in Installation

This inverter model is convenient in its installation like they come with an aluminum case design, small in size and light weighted. It also has a DC combiner box which decreases the system overall cost. This inverter provides a separate area for maintenance due to which its repair becomes easier.

The dimensions of this inverter are 800 x 550 x 280 mm with the net weight of 68 kg. This inverter provides an altitude of 3000 m while working. The LCD display size is 3.5 inch with that screens data in English language.

Environment Suitability

This solar power inverter gives the operating temperature ranging from -25 degrees Celsius to +60 degrees Celsius with the ambient humidity ranging from 0 to 100% (non-condensing). It comes with an intelligent fan cooling method which prevents the inverter from overheating. Moreover, the consumption of this inverter at night is greater than 0.6 W – consumption at standby is about 10 or greater than 10 W.

Protection

This inverter model comes with a well-protected body and provides more protection through their intelligent features. It offers an internal over-voltage protection which prevents the inverter from over-burden or sudden switching off due to overheating. This also gives thermal protection, AC/DC surge protection, and AC short circuit current protection etc.
