what are advantages of Solis 7-8kw High-Efficiency Inverter?

1. High-Efficiency Performance
The inverter was designed to deliver the best possible energy conversion performance under the harshest circumstances by having the highest efficient use of solar energy in all conditions. The intelligent thermal control design of the system provides stable operation under extreme temperature conditions, while the enhanced MPPT (Maximum Power Point Tracking) ability will allow for ongoing alterations in solar input levels. Through constant adjustment, maximum energy production and extreme low energy losses can be achieved. Additionally, increased profitability will be realized for the entire system.
2. Smart Grid Integration
The inverter has been specifically designed to integrate into today's energy networks easily. It uses a two-way communication protocol to connect to the solar system and energy storage battery. Thanks to the inverter's adaptive technology, users can switch between being grid-tied to being off-grid seamlessly. This makes the inverter particularly useful for situations where users want to take advantage of both modes simultaneously.


3. Robust Build Quality
This inverter has been constructed of heavy-duty materials designed for operation in a wide variety of environment. The enclosure has IP66 rating so dust cannot enter into the enclosure and be damaging to the inverter. The inverter also has a precision-sealed (dustproof) design which allows the heat from the components to be passively expelled through the enclosure, eliminating the need for forced air or other active means of cooling. Because of the passive cooling method used, there will be reduced mechanical stress and wear on the inverter's components over the long term. Also, there are redundant circuits located within the inverter, which will provide protection from damage caused by incoming power surges, high temperature, and short-circuited connections. Therefore, this inverter can operate efficiently in harsh conditions for many years.
4. Versatile Applications
This inverter is designed to meet a variety of requirements from home rooftops to business solar facilities. This inverter also works with battery storage systems providing homeowners with the electricity they need even if their local utility company cannot supply them due to an outage. The ability of this inverter to be used with many different types of solar panel configurations and grid standards makes it a great option for both installers and users.


5. User-Centric Features
Easy to Monitor: The built-in connection options allow users to view energy generated, consumed, and the condition of the system from both their smartphones or computers and in real-time.
Less Time to Repair: A simple inverter design means less complexity, which means a reduction of time and money out on repairs and/ or downtime.
Ultra-quiet: State-of-the-art sound-dampening technology offers the end user the silence they expect from a solar installation.
