Upgrading Old Huawei Inverter Without Replacing Current System

Many homeowners invested in string inverters for their solar panels, like the Huawei. However, these older inverters often cannot integrate with modern EMS solutions or connect to batteries. This means that when homeowners want to upgrade and add a battery, they face a tough choice: Replace their existing inverter—which was once a costly investment.

• In the worst case, they face replacing both the inverter and solar panels—an expensive and unnecessary solution.

When house doesn’t have a battery, these are these limitations:

❌ You can’t store energy when electricity prices are low and use it when prices are high.

❌ You rely more on grid electricity when the sun isn’t shining.

❌ You can’t take the advantage of savings and cash earnings with MarkeDroid.

MarkeDroid’s Unique Solution

✅ Save on energy bills through battery arbitrage and make cash with participating in the grid.

Real life Customer case

One of our customers with a Huawei SUN2000-20KTL-M wanted to install a battery but couldn’t due to compatibility issues. Instead of replacing everything, we integrated a hybrid inverter — Solax X3-ULT alongside their existing inverter. This allowed them to:

🔹 Add a battery and store excess solar energy.

🔹 Use MarkeDroid’s HEMS for smart, AI-powered energy management.

🔹 Optimise their system without costly replacements.

1. Battery Arbitrage is essentially storing energy when it’s cheap and using it during expensive peak hours. The amount shown is the customer’s total savings.
2. Grid Balancing refers to buying energy from the flexibility market, using the battery’s energy in monetary terms. The amount shown is the customer’s total cash earning.

When we say MarkeDroid is the world’s most adaptable home energy management platform, we mean it! MarkeDroid helps both installers and homeowners profit from turning traditional energy systems into smart, AI-powered solutions.

With MarkeDroid, upgrading doesn’t mean starting over. It means making your solar investment work smarter.
