i admit i have done quite a lot of reading of forums and resources at this site and its left me fairly confused, all i really want is a list of items i am going to need to monitor my household electric and solar PV.
Apologies if this has been asked before, i have read a lot of newbie questions but with information overload i am struggling a bit.
What i want to monitor:
Household electricity (Incoming and outgoing)
(Later in the year i will be adding a battery system but ignore that for now)
The Solar is in the garage, i have 2 strings as i have one solar array on the roof of the main house and one on the garage, both plugged into a single inverter that can handle both strings. The battery will also be fitted into the garage in March.
I do have adequate WIFI available in the garage even when the up and over metal door is closed as i have reliable data from the inverter coming in over wifi.
I do have a spare PI3 kicking around including a case and power, so i dont want to buy another, but other than that i have nothing, though assume i can download images and get the PI3 working.
I assume i am going to need the following hardware:
Inside the consumer unit (Kitchen) mount the PI which will need me to purchase and fit an “RFM69Pi” in order to receive data.
As the Pi and its receiver cannot actually monitor anything directly i am also going to need to add an “emonTx V3” to the equipment to be purchased list.
As far as i can make out that leaves clamps, how many clamps am i going to need to measure electricity in and out of the property and solar produced, sounds like three to me but i am not certain.
and an AC-AC Power Supply Adapter - AC voltage sensor (UK Plug) to power the emonTx
So Bill of materials:
100A max clip-on current sensor CT * 3?
anything obvious i am missing?
am i going to need one emonTX in the house for the grid electric and another in the garage for the Solar? The solar does have a small consumer unit next tot the house consumer unit.
