Power bill from 11 Dec to 10 Jan was $172.05 CR. This comprised $110 for imported energy, $32 for line charges and an export credit of $282.

We had the house (10kw) installed at the end of Nov so this covered the whole month, but the stand alone garage (5kW) only came online on 3 Jan so the bill does not fully reflect our setup yet.

We have an Iammeter 3 phase meter at the grid connection, this showed we consumed 382 kWh from the grid (Night 312, Day 72) and exported 1655kWh. These figures are close to the figures on the bill so the meter is within 1% accuracy.

It's a little hard at the moment to figure out self consumption as most of the load is in the house, except when we charge the car which is plugged into the garage so the consumption figures are not included on the house inverter meter. Although we don't use the car much so maybe 50kWh of charge over the month.

The house consumed 704 and it looks like 377 of that was self generated.  I have not made any effort to move any of the night time loads yet as our export rate and night time rate are very close (17c vs 18.4c).

I am working on some automation for hot water heating and car charging during the day to keep our exports and imports lower.
