Hi All
Not an electrician and some of this is now going over my head, but new PV install with Solis inverter and Fox battery as above...
Issue is according to Solis cloud data we are seeing energy production but battery is only charging "slowly" and at times most of the energy produced is going to the grid.
We have checked standard setting for self use is set, I have been onto installer and also Solis support and am getting conflicting information.
E.G.
Yield 2.15 kw. Battery 23% and being charged at 0.653kw, house consumption 0.482kw and 1.015kw going to grid.
We have requested system is set to self use - priority - House then battery then grid. This is what we were told it would do but so far has failed.
Since install about 2/3 weeks ago we have exported almost 14kw to the grid and have on average only had a battery charge of around 30 % during the day...
Solis are saying that " the charge limit of battery is 12A . 12A x 50V = 600W limit of charge power. So the rest will go to grid"
This kind of supports the data example above however, I have disputed that as the battery should be able to charge at 3000w I believe looking at information.
Installer says I need to talk to my boss, it shouldn't be doing that
I have in fact seen yesterday BMS Charge current limit was 50 A with a voltage of 52 ? 50 x 52 = 2600w
Does this battery ONLY charge at 600 or so watts ?
Is there anyone who has the same set up and no issues?
Is there anyone who has experienced the same ?
Is this a BMS issue re Charge rate?
Is it the settings on inverter maybe ?
Is this possibly an issue with CT clamps being installed wrong?
Any pointers would be great as right now we are "losing" over 10% yield to grid and then buying back ... and I am getting the run around - just want to be able to press either the installer or Solis to get resolution.
Any help really appreciated!
