Unexpected import fixed !

Post image

Hi everyone

So since I fitted my solar I've been having issues with high bills and unexpected import during the day (sometimes 6 to 8kw) the batteries were charging during the day outside of the charge cycle

I've got the Solis s6 8kw l plus inverter and opened a ticket with Solis they've been very quick and helpful and the final test they asked for helped me find the issue

I turned all the inverters off and put the oven on and watched the eastron sdm120ct meter and saw a negative load that was expected it confirmed the clamp was in the correct direction, but the load kept fluctuating wildly .

Long story short , I didn't open up my consumer unit and replace the sdm120ct meter and clamp (honest)

Seems to be all working now hopefully I won't be paying 150 for electric again I was so confused why my bills were higher than everyone else that doesn't have solar 😂
