A Superior Engineered Solution

Unmatched Solar Harvesting

The Must inverter's Dual MPPTs are a game-changer. You can install solar panels on two different roof sections (e.g., east and west) to capture sunlight throughout the day, maximizing your energy production and ensuring the high-capacity Deye battery is charged quickly and efficiently.

Intelligent & Communicating System

With CAN bus communication, the Must inverter and Deye battery "talk" to each other. This allows the inverter to intelligently manage the battery's charge and discharge cycles based on its precise state-of-charge, significantly extending the battery's lifespan and ensuring system safety.

Frequently Asked Questions

What is the main advantage of the Dual MPPTs?

Dual MPPTs allow you to connect two separate solar panel arrays that can operate independently. This is ideal if you have roof sections facing different directions, experience partial shading on one part of your roof, or want to use two different types of solar panels. It maximizes your total power generation.

How many solar panels should I use with this 6.2kW combo?

To maximize the inverter's 8000W PV input, we recommend an array of 12 to 16 high-quality solar panels (e.g., 550W panels). You can split these between the two MPPTs (e.g., 6 panels on one and 6 on the other) for optimal performance.

Is this system powerful enough for a small business?

Yes. With 6200W of continuous power and a 12,400W surge capacity, this combo is an excellent choice for small offices, shops, or workshops to power computers, lighting, refrigerators, and even some light machinery.
