What Makes the Solis Hybrid Inverter Stand Out?

Among a sea of inverters available in the market, Solis Hybrid Inverter stands head and shoulders above its competition. But why is this inverter unique?
The answer lies in its impressive ability to handle both solar and battery storage. The Solis Hybrid inverter has been designed to efficiently manage and regulate the conversion of DC power from solar panels and energy storage into usable AC power for your home.
It’s like having two devices in one, ensuring an efficient, streamlined solution that optimizes both the performance of your solar system and the use of battery storage.

Efficiency and Reliability

At the heart of the Solis Hybrid Inverter’s functionality is its remarkable efficiency. This device features an impressive maximum efficiency of 97.8% and a European efficiency of 97.2% at full load. With such high efficiency, homeowners can extract the maximum possible energy from their solar panels and storage system, thereby ensuring better energy savings and return on investment.
Reliability is another key strength of the Solis Hybrid Inverter. This robust device is designed for longevity.
It has an IP65 rating, meaning it’s dust-tight and protected against water projected from a nozzle. Its build quality and durability make it an ideal choice for the harsh and diverse climate conditions we encounter in our installations.

Features and Functionality

The Solis Hybrid Inverter is loaded with features that make it a smart choice for any solar installation. One key feature is its ability to function both on-grid and off-grid, providing homeowners with the flexibility they need to manage their energy use efficiently. In the event of a power outage, the inverter can switch to off-grid mode, using the power stored in the battery to keep essential loads running.
Further, the Solis Hybrid Inverter offers dual MPPT (Maximum Power Point Tracking) inputs.
This means it can handle inputs from two separate solar arrays, each operating at its maximum efficiency. This is particularly beneficial for homes with multiple roof orientations or shading issues, ensuring optimal solar energy harvest regardless of the sun’s position.

Monitoring and Control

User-friendliness is another major plus of the Solis Hybrid Inverter. The device comes with a built-in monitoring system that allows homeowners to keep track of their system’s performance through a simple and intuitive interface.
Through the Solis app, users can monitor real-time data, check historical records, and even receive fault notifications, making it easy to stay on top of their solar energy production and consumption.

Battery Storage with the Solis Hybrid Inverter

Battery Charging

One of the crucial functions of the Solis Hybrid Inverter is its management of battery charging and discharging. Integrating a battery system with your solar panels can significantly enhance your energy independence, allowing you to store excess solar energy produced during the day for use at night or during power outages. Here’s how the Solis Hybrid Inverter helps optimize this process.

Optimized Charging Strategy

The Solis Hybrid Inverter employs an intelligent strategy for charging batteries. This ensures maximum usage of solar power and increased energy savings.
During the day, when your solar panels are generating more electricity than your home is consuming, the Solis Hybrid Inverter directs this surplus power to charge your battery storage system. This means that instead of sending excess power back to the grid, you’re storing it for future use.
This charging strategy allows you to make the most of the solar power you generate and reduce your reliance on grid electricity, saving on your energy bills and increasing the overall efficiency of your solar system.

Load Shifting and Peak Shaving

Battery charging managed by the Solis Hybrid Inverter can contribute significantly to two effective strategies for energy usage optimization: load shifting and peak shaving.
Load shifting involves charging the batteries during off-peak times when electricity costs are lower (such as during the day when solar power is abundant) and using that stored power during peak times when electricity costs are higher (like in the evening).
Peak shaving, on the other hand, is about using the stored energy in the batteries to offset high power usage during periods of peak demand. By doing so, you can avoid or reduce higher energy rates during these times.
Both strategies can lead to substantial energy cost savings and are made possible thanks to the efficient battery charging process offered by the Solis Hybrid Inverter.

Seamless Switching between Power Sources

Another great feature of the Solis Hybrid Inverter is its ability to seamlessly switch between power sources. If the power stored in the battery is depleted, the inverter will automatically switch to draw power from the grid (or a generator if available). Conversely, once the battery is charged sufficiently, the inverter will switch the power supply back to the battery, minimizing your use of grid power.
This feature ensures a reliable power supply, whether you’re self-consuming your solar energy, using battery power, or drawing from the grid when necessary.
In conclusion, the Solis Hybrid Inverter offers a sophisticated and efficient solution for managing battery charging in a solar-plus-storage system. It ensures that homeowners can make the most out of their solar energy, leading to higher energy independence and significant cost savings.
