Products Description
What are advantages of Solis 3-6K Low Voltage Inverter?

1. Maximum Power Generation, Night and Day
Don't just generate energy; start maximizing your energy independence.
Dual-MPPT Conversion Performance: Our optimized technologies safeguard the unused portion of your solar array and continually run the remaining elements at maximum output, even partially shaded or facing a different direction. By remaining longer at maximum orientation, you ultimately produce more energy from the morning sun to the horizon at dusk.
Best-in-Class Conversion Efficiencies: Our inverter converts more of the leisurely produced, clean DC power into usable AC power for your home. This means creating less heat energy loss and most of that clean sunlight can better power your appliances and reduce your electric bill.
Wider Operating Voltage: Our inverter can make power earlier in the day and later into the evening hours, during low-light conditions. All of this translates into productive hours of operating for every ray of sunshine.60% PV input capacity
2. Smart Control & Effortless Monitoring
Stay connected and in control of your energy with powerful next-gen smart features.
Integrated Smart Energy Management: This future-ready inverter integrates seamlessly with battery storage systems. It intelligently directs the energy flows for you so you can store extra solar energy for later use when the sun is not shining-at night or during power outages-providing you true energy independence.
Real Time Remote Monitoring: Monitor your system's performance from anywhere in the world. Our simple monitoring platform is easy to access on your smartphone or computer and shows clear data, in real time, about the energy you produce and use, with valuable insights at your fingertips.
Proactive Diagnostics & Updates: The system constantly monitors its own health and can proactively notify you of problems before they become real problems. With over-the-air system updates, your inverter can stay optimized and secure with zero effort from you.


3. Built for Durability and Peace of Mind
We build durability and safety into the design of our products so that you can trust they will last.
Durably Designed for Longevity: The fully sealed (IP66), enclosure of the Solis S5-EH1P is made to be durable for harsh outdoor conditions, whether it is driving rain, dust, or extreme temperatures - this allows for dependable performance for years.
Comprehensive Built-in Protection: Your home's safety always comes first. The inverter is equipped with multiple layers of protection against grid anomalies, lightning surges, and internal faults whilst ensuring automatic safe shutdown & operation to keep your family, home, and utility grid safe.
Silent and Inconspicuous Operation: Designed with a quiet fanless or ultra-quiet design, the inverter will never disturb your clean energy experience at home. Enjoy reliable, clean energy without disruption.
