I have added a 9.5 kw battery to my solar system which was installed 9 years ago
The FIT meter is now adding KWH when there is
no solar even overnight
Also the isolation switch for the solar array will not turn off the system
The solar inverter has a lower reading to the FIT meter
Any ideas as to why this is
Thanks
If you have a FIT system and want batteries added you have to have the inverter for the battery downstream of the FIT meter. With an AC battery system like AiO that’s easy as the Solar inverter generates, goes through the FIT meter and the batteries are charged, when they discharge the built in inverter is connected to your distribution board, therefore not affecting the FIT meter.
I suspect you charge the battery which when it discharges somehow uses the same inverter that the solar panels use, ie. upstream of the FIT meter. I would suggest you need a second DC to AC inverter that the battery discharges to that is connected to your consumer unit?
I might be completely wrong as I base this on being an AiO user.
My first installer of GivEnergy batteries was a complete incompetent - he subcontracted the work to electricians that appeared not to have been trained on Givenergy kit, and used his brother who was not even an electrician to supervise their work. This shower installed the wrong meters which could not record generation properly.
I had to get in a completely different GivEnergy electrician in at additional cost to sort it out.
Im having similar problems. I have an old fit system (15 years) and decided to renew the inverter and have a battery.
Advised to go with a hybrid inverter and change the generation meter to a bidirectional net meter and was assured i would track my generation from the panels and still get my fit payments. 6 weeks on and still trying to get sense out of the net meter reading, while ot is increasing it is not tracking what i generate, even the installer is puzzeled.
Anybody out there who has tried to combine a hybrid system with an old fit? I would love to hear of their experiences good or bad
