Hi Folks, I've currently got a 5 kWp PV mated to a 3.68kw SolarEdge Inverter. Also have optimisers so can't really change inverter without spending a whole lot more on getting rid of the optimisers.

Also have a myEnergi Zappi EVC

So the plan is to buy an EP12 Plus and just set it up as an AC-coupled system, mated to a Fox Inverter.
In the future, when the SE inverter packs in and I'm ready to upgrade the PV array, I could hook it up to the Fox Inverter.

Which series of Inverter would be suitable?
I'm currently looking at the F6000 as it seems good value for money and is a Gen3.

As I will be buying the battery and Inverter myself (I've seen good deals) I intend to employ the services of a competent sparky on day/job rate. Haven't started searching yet but other than NAPIT/NICEIC and asking them some basic questions about their experience of installing inverters/battery are there any questions you think I should ask for an install only job?

They will of course need to supply their own cables and isolators etc.

I was having a read of the manual myself, it looks relatively simple for a competent spark

For CT clamps I will use Pin 1 to go on meter tails (to monitor import and export) and Pin 2 to go on the PV cable (to monitor generation)

have I missed anthing?

The EP12 is just a high voltage LFP battery with BMS, it needs to be connected to a Fox hybrid inverter to operate as the AC coupled system, at a later date you can connect your PV strings (DC only) to the same inverter if required.

The F6000 is a solar only inverter it will connect to a DC PV string but cannot be connected to a battery.

You should be looking at an H1-6.0 which can be used as an AC coupled system with the EP12 connected to it - and then if you want to connect a DC PV string to it you can as it has 2 MPPT inputs.

As an AC coupled system it will have a CT clamp connected on the live cable of your supply meter and it will be able to detect any excess power being generated by your existing inverter and use that to charge it’s battery, or if there is no solar it can supply your house load as a hybrid inverter from the EP12 battery.

There are some larger domestic single phase systems such as the KH inverter which starts at 7kW (going up to 10.5kW) and that has 3 independent MPPT’s, going up to 4 MPPTS on the KH9 or above.

Thank you so much Dave. Seems I was barking up the wrong tree with the F series. Is the H series only available as a Gen 1/2?
Also for clarity, are there 2 versions of the H1 as I’m seeing variation of H1 and H1/AC1
