Smart Home Automation Arduino Mega IoT
Rev87 of C++
Start 4 Oct 2016
Cape Town, South Africa
9 x 305W Canadian Solar PV panels
Microcare 60A MPPT
8 x Sonic 105Ah Gel Batteries
MLT Drives 4KVA Pure Sine Wave inverter
Flat Plate thermo syphon solar collector and GeyserWise
Aduino Mega , sensors and 8ch relay board
.75KW pump with pressure/low level/ overcurrent
Annual average daily power usage before PV 7kWh per day Post installation approx 15kWh per day .
Payback period approx 5years at 7kWhpd then approx 20years “free power”
Work in progress.
Rev 86 of software development
3. Challenges,
1. RS232C comms to MPPT( to download Battery V and Current and PV power)
2. Creating stack to prioritise use of excess capacity automaticlly:
1. Battery boosting at 45V from utility. (if NO utility shed loads) Also for total computer failure, or MPPT or Batteries or Panels.
