Firstly, looks like the new boards has broken the table formatting. Anyone have a link for formatting posts - even changing font, etc? - edit: used a 'code block' to get fixed width formatting.

In terms of the month - it was not great, 100kWh down on the last 3 months - and if it was not for last week it would be have been in March territory - that said, I had the lowest import so far, partly because i was away for a few weeks. My batter gets me to about 1-2am every night, so I only buy 1-2 kwh a day to get me to about 6-7am when the solar kicks in.

August 410kwh generated from 5kw array. 75% average usage rate

Best 13th 12.8kwh

August Stats

6.2kWp (2.8 south/3.4 west), 20kWh battery, Zappi & Eddi – Donegal

Generation – 556.3kWh (down 2.8% from last year)

Export – 52kWh (down 64.6%)

Import – 128.9kWh (down 57.4%)

Best day - 24th, 29.3kWh

Worst day - 29th, 5.3kWh

First month with the home build battery and the change is clear. Slightly less generation than last August, but a 64% drop in import and 57% less exported.

It would have been better too, but I had a few tweaks to make when putting the battery together and had to manually charge it a few times to set the top level, plus that resulted in unnecessary export.

I'm pretty fed up with myenergi. The signal keeps dropping between the various bits and it's blind luck these days whether it properly charges on excess.

August 582 kWh

Best day 24th 28.5 kWh

Worst day 20th 4.7 kWh

Total since install 2.36 MWh

Total for August 235kW drop down from 330 in July June and May were 335, so far since install in April to now 1330kW

Best day was 13.2kW 24 August

Worst was 4.2kW on the 5 August

2.5kW based in northeast Louth and ssw

Bill just in for July/August - €93. Same period pre-solar was €271. July was pre-battery increase.
