Remote Area Solar Mini Grid Standalone Three Phase Prepaid Energy Meter
This standalone three-phase prepaid energy meter is specifically designed for remote area solar mini grids, offering reliable and efficient energy management solutions. It features a robust design suitable for off-grid applications, ensuring accurate measurement and secure prepaid functionality.
The meter supports high-power solar mini grids, with a three-phase four-wire configuration capable of handling currents from 10A to 100A and a voltage range of 230V (60%~120% Un). It operates on a 20-digit STS token system, automatically shutting off power when credits are depleted. Additionally, it includes tamper detection and event recording features to enhance security.
With its keypad interface, users can easily manage prepaid operations, while the optional RF communication module enables remote data collection and monitoring through an AMR (Automatic Meter Reading) system. This meter is ideal for remote areas where traditional grid infrastructure is unavailable, providing a sustainable and user-friendly energy solution.
