1、 How should new energy supporting instruments be selected?

1. First, clarify your specific application for the scenario (household, industrial and commercial, photovoltaic, energy storage, charging station).

2. Regarding parameters, focus on key indicators such as accuracy, communication methods, and response speed.

3. After reviewing the certification, select products that meet regulatory requirements based on the location of the project.

IIThe selection of supporting instruments for new energy needs to be based on the specific application scenario to choose the appropriate instrument type and parameters. The following are the key selection points for the main scenarios:

1. Household photovoltaic/energy storage scenarios

Instrument model:

ADL400N series or ADL200W series

Core requirements:

Requires milliampere level accuracy, supports phase sequence self adjustment, prevents equipment from being damaged due to reverse phase, anti backflow function: (prevents reverse power transmission from the grid), and has MID/UL/CE certification.

The advantages of ADL200W series products include WiFi/LoRa wireless communication, 50ms fast response, anti backflow control, bidirectional metering, and support for self diagnosis. Easy to install, suitable for low-voltage scenarios such as home roofs and balcony photovoltaics, simplifying wiring.

ADL200W series models

2. Industrial and commercial energy storage scenarios

Instrument model:

DTSD1352 Quick Flash Version or ADL200 Quick Flash Version

Core requirements:

50ms fast response, real-time blocking of reverse current with Class 1 accuracy, supporting RS485 communication, ensuring time of use electricity price settlement

3. Charging pile scenario

DC charging station:

DJSF1352-D300 型

(Supports DC current up to 300A)

Compact size (only 1/3~1/4 of traditional split type), suitable for charging station space

Integrated design of splitter, supporting DIN35mm rail installation

Key indicators for selection

Accuracy level: Class 1 accuracy is required for industrial and commercial scenarios, and milliampere level accuracy is optional for household use

Response speed: Industrial and commercial energy storage requires a quick response time of 50ms to prevent backflow risks

Certification standards: VDE certification is required for exports to Europe, and MID/UL/CE certification is required for domestic exports
