Hi ,
I have had the above equipment installed for a month. Its retro fitted as ac coupled because I have an existing solar panel installation with 2.4 wp solar panel and a 2kw Solis inverter, operating under the FIT tariff. The fox equipment is installed on a separate circuit between the house consumer unit and the house meter, controlled with a ct clamp on the main house load. There's no second ct clamp monitoring the existing solis inverter. its been left on self use since installation.
I'm experiencing multiple issues including the fox system importing from grid when there's lots of battery power available - for hours albeit at c 200 - 500w, exporting to the grid when the battery is low on charge for hours, and also apparently going completely haywire discharging the battery at 6kw exporting 2-3kw to the grid and seemingly inventing house loads. These are all apparent and recorded on the v2 web app analysis graph. Its does operate relatively normally as well !
I have occasionally tried to correct its errant behaviour using the work mode schedule for forced charge and discharge but it generally just ignores the schedule. Its had its firmware updated by fox support twice, doesnt seem to fix anything.
Has anyone else this style of installation, where the system either operates correctly or incorrectly? Any ideas/feedback gratefully received.
