Solitec Metering Solution for Home Storage Systems

Comparison of Anti-Backflow Solutions for Home Storage Systems

 

Issues with Traditional CT Solutions:

• High cost: Many external CT devices required, high cost of built-in CT meter devices
• Complicated wiring: External CT installation is cumbersome, affecting aesthetics
• Large space requirement: Traditional meters take up a lot of space, high installation cost
• Low integration, complex wiring: Three-phase systems require three CTs, reducing wiring efficiency
• Risk of incorrect installation: Phase sequence errors in three-phase CTs, single-phase CTs may be wired incorrectly
• Poor compatibility with inverters: Analog signals need to be transmitted to the inverter, which outputs the metering results with poor accuracy, requiring additional power bias correction to compensate for CT sampling errors

 

Advantages of Solitec Smart CT Solution:

• Cost-effective: Combines high reliability with low cost
• Space-saving and cost-saving: Can be directly installed in the original distribution box without additional meter installation
• High accuracy: Provides superior measurement accuracy compared to traditional CT solutions, suitable for modern home energy storage systems
