We have just had a PW 2 installed along with a 5kw solar system.
The app is showing that during the day the solar is generating around 3kw which is feeding the house, or feeding the mains - but it currently doesn't seem to want to charge the PW. Earlier it was charging and it got up to 86% but for the past couple of hours it is sending most of the power out to the grid (and we aren't on a buy-back tarrif yet so this seems a little pointless).
Also, even though the battery charge has been above 75% for the past 48hrs it hasn't yet actually supplied any power to the house... when there isn't enough/any solar then the power comes from the mains instead of the PW.
Our installer says there it will take a week for the system to "learn" and it won't work as we expect until that time.
Is that true? Will it be a week before we can actually use any power from the battery? And how can to force the surplus power to feed the PW instead of the grid?
Thanks for any advice.
