Hello all. Complete newby here… so please put replies in very simple language please
My installer has been less than useless as I had an issue with my Solax system. After speaking to solax over a number of days they determined my battery was faulty. The battery was 4.5kwh and as they stopped manufacturing those batteries they sent me 2x 3kWh batteries.
The installer very reluctantly came to fit them but there has been silence from them since.
The system I believe I have is:
I have 5kw panels on my roof
I have a solax X1 AC inverter
I have 2 x solax 3.1kwh batteries (T4)
I have a growatt inverter (the installer said I have 2 inverters… one for the batteries and one for the solar)
The issue:
Since the batteries have come on line I have been using 50% MORE energy. As an example, on 2 similar days in terms of weather and usage… on day 1 I had no working batteries (prior to installation of replacement) my energy use was 14.08kwh that day. On day 2 the day after my new batteries were fitted I used a whopping 24.68kwh!!
I was in self use and to my little brain it appeared that the system was contestants charging my batteries to the grid. Spoke to solax and they said my inverter wasn’t online and they did something and put it into the correct mode which the installer hadn’t done.
Fast forward a week to today… energy still high, but now my issue is that I’ve managed to put it into force time to match my octopus flux tariff (it force charges my batteries at 2am to 5am to 100%).
My question is how to I prioritise battery use over grid as I am still using the grid despite having full batteries ? I haven’t got a pic but an example was my load in my house was say 2.5kw, my panels were generating 500w, my battery was at 98% providing 500w and the grid was providing the bulk?!
Thank you so much everyone
