Generation Wiring

Appliances Automation

Generation Plan

• 10kWp of conventional generation system (1phase or 3phase) with battery connection

• Use of BIPV along with micro-inverter for easy local grid connection

• Communication of home automation hub with inverter to fetch inverter

data

Wiring and Switchgear

• Use of modular wiring with connectors to reduce construction time

• Wiring design to facilitate plug and play modules

• Possibilities of using Flat cabling system to ease future expansion

• Use of smart communicable MCB’s with remote switching if possible

• 3Ph grid to 1Ph distribution to avoid grid unbalancing

• Change over of critical loads from 1Ph to other in case of single phase failure

• Use of services room to place power guzzling appliances at single place

• Communicable touch switches with remote turn on/off and dimming features

• Wall mountable USB, Telephone, TV socket, LAN sockets, etc
