3 eSite x10

3.1 Overview

eSite x10 can be provided with AC power supply from genset and grid and with DC power supply from solar arrays. The supplied power is used to support customer load and to charge a battery bank. The AC power supply is converted into -48 V DC through rectifiers in the Main Compartment. The DC power supply is converted into -48 V DC through solar converters in the Main Compartment. Switching between the connected power sources is automatic through the patented silicone controlled rectifier (SCR) functionality. eSite x10 sends start and stop commands to the genset(s) automatically when required. If solar arrays are installed, they are under regulation from the internal solar converters at all times and will supply power when the weather conditions are favourable.

The Main Compartment contains:

Rectifier x 3
Solar converter x 3
SCR (replaces standard ATS)
Current, voltage, frequency and temperature sensors
Wi-Fi
GSM
Main Controller

🚨 Caution

The Main Compartment must be connected to the Connection Compartment only, unless a written statement from eSite Power Systems permits other connectivity devices. No third party connection device can be used without explicit consent and approval by eSite Power Systems. The Connection Compartment and the power connectivity is subject to regulatory control by eSite Power Systems.
