Hey everyone,
I need some help and advice. My Solis Inverter still draws minimal energy from the grid even though my solar panels are generating enough energy for use and storage. The problem is that this minimal amounts are costing me almost £1 a day, around £30 a month.
Is there anyone of fixing this issue? Solis says there is nothing that can be done at the moment but have raised a ticket that has not been allocated to anyone. Would this be the same issue with all inverters?

Hi
Welcome and I hope below answers your question:
Yes the PV systems all draw (at times) an amount from the grid.
I have been monitoring mine for weeks and can confirm there are times there is :
A) a trickle from the grid, a cloud can drop PV suddenly and if charging a battery the grid may step up while the battery charge is adjusted
B) a trickle TO the grid, this happens most when PV panels suddenly gain more sun, or when battery is charged.
C) when the battery falls to 4% on my system the trickle to the grid is used to maintain the management of the PV system.
Pretty sure the net benefit of solar far exceeds this gain/loss scenario but it appears to be just the way it is.

+9Well yes but in various ways. If the communication to the inverter is not good enough, then it will not know how much power to supply to the house.
If it is just low output (as the warning suggests), then there may be a wiring or intermittent problem.
Alternatively as I mentioned to begin, the inverter may be exporting rather than supplying the house - that again could be caused by several things including configuration
