Thanks for the detailed info! A couple of questions if you have a sec:
1. I assume the yellow readout is cumulative, not current usage?
Yep it was probably 0 when you got the solar installed. so spreadsheets out and record time of reading.
2. So if the LEDisn't blinking it means I'm generating enough from the roof and not buying power?
not 100% sure i would need to google for the manual but yes if you don't see a blink and the arrow is going the other direction your exporting.
3. Is there another way to gauge current usage other than counting LED blips?
not without extra hardware
What I was hoping to do was gauge what each device group uses and calculate how much each group is eating up. Lighting, fridge, pool, computers/TVs, kettle, and so on. I can't get my head around how I could do that with LED blips. I wanted to start with everything off then switch things on and off one at a time, noting the readings.
Thanks for the quick reply. Just had a longer look at the metre based on your explanations.
I just calculated that the LED is blinking 21 times per minute, 1260 per hour.
Did you say that 800 per hour is 1kWh, meaning we are currently using about 1.5kWh? Or do I have that completely wrong?
Looks like we have exported 6,858kWh and imported 36,224. Am I right in saying that we first use the solar, export any excess, and import any deficit? In other words the solar that we immediately use does not appear in the export because we didn't sell it back?
We have two inverters and when I combine their total output since the start it's about 27,000kWh. Does this mean we used about 20,200 and sold back 6,800?
not sure about the led blink... i actually couldn't read your picture 100% of the writing under the led so if you could read it again for me.
yes solar generated 27 000 kwh you sold 6858 kwh back to the grid. so you used around 20,200kwh yourself so you count that as electricity not purchased ! so times that number by how much you pay 20-30c kwh and that's how much your solar has saved you $6k.
I thought some got lost along the way, I forget what percentage, but not quite all you appear to generate on your inverters is usable electricity. I had never found a cumulative reading on my inverters before (I only knew the daily reading), but when Jim metioned in this thread I went and had a look and now I've found it, Eall is the cumulative reading and Etoday is the total for today, so we are both learning a lot from this discussion, Jim
