Battery Self install of battery storage

[littlespark]

I’ve been doing a fair bit of research on adding battery to my own house… there has been mention of it on other threads, but I’ll start a new one just for this.

Have been asking the “experts” in the local wholesalers, but I know they are salesmen first, and experts second.
However, saw this advert…



I’ve already got PV, with a good FIT price, so don’t want to affect that in any way.

The guy in YESSS said replace my existing inverter, and mount the battery’s next to it in the attic, but someone else has told me they are not to be in an attic for fire risk.


Can I fit the new inverter and battery’s separate to the PV? And not be limited to the <4kW?

The house heating is gas, but we can fit a few electric heaters to back that up…. Same with changing the gas hob to electric.

Great stuff ! Any chance you could post a diagram of your setup ??

Yes.. I’ll get one made up… but I’ll make sure it works first.

This morning brought overnight consumption of 4 units. FIT meter hadn’t gone up at all, which is expected with no sun.
Battery’s have remained at 100%…. So it appears the battery isn’t feeding the house load when I want it to.
Maybe just a simple mistake with the settings… will have a look tonight.

I might just have to get this other CT and meter to monitor the PV production after all… although don’t think it should be needed.

Still thinking of extending the PV cables down to the new inverter and taking out the old one.
Adding 10m of the same size DC cable to the string shouldn’t be a problem, should it?
The panels can only produce so much voltage… and if that’s 2 or 3 volts down because of the length…. It won’t cause a problem.
