New Options for Balcony Solar Power Systems

Residential solar power refers to small-scale photovoltaic power generation systems installed on household rooftops, balconies, and other areas, providing electricity for the residents themselves. These systems can be connected to the grid or combined with energy storage for off-grid emergency power, making them a mainstream solution for household energy self-sufficiency.

Optional Configurations:

* Energy storage battery: Stores excess generated electricity for peak-shaving or emergency power during outages.

* Monitoring equipment: Acrel ADL200W/ADL400W electricity meters, used to measure power generation and consumption.

* Anti-backflow device: Required in some countries to prevent excess electricity from being fed back into the power grid.

Compared with traditional anti-reverse current meters, the new series offers the following major advantages:

Compact structure: 1P, 18mm standard DIN rail design, supporting four application scenarios: one-way single-phase, two-way single-phase, one-way three-phase, and two-way three-phase.

Plug-in current transformer: The current transformer adopts an integrated design with an RJ11 interface. Plug-in installation with the meter and three-phase yellow-green-yellow color coding reduces the risk of incorrect wiring, such as reversed current. Furthermore, if the current transformer and meter are installed far apart, a standard RJ11 extension cable can be used.

Plug-in voltage terminals: The voltage terminals are pluggable for easy installation, and the terminal wiring uses a press-fit design, reducing wiring difficulty and improving efficiency.

Fast electrical parameter updates: Real-time capture of voltage and current changes, updated every 50ms. Wireless Communication: Supports 485 and Wi-Fi communication. 485 supports the Modbus protocol, allowing all required electrical parameters to be read with a single data request.

Wi-Fi communication supports Modbus TCP or HTTPServer protocols, with built-in or external antenna options.

Phase sequence diagnosis: Supports wiring diagnosis, identifying abnormal wiring situations and providing adjustment suggestions.
