Can you recommend a good home hybrid inverter?

Fingers

Hello, Can anyone recommend a good hybrid system for my UK house?

There are so many out there and I have so little time, so if you could point me in the right direction I would be grateful.   

I'm looking to lower my electricity bill

What I require:

The ability to use off the shelf lifepo4 batteries.

Not require specialist BMS.

Mains as a backup when batteries & solar are low.

Use solar on a sunny day when the batteries are charging.

No exporting to the grid.

Wire direct to the house fuse box, and without running new sockets in to the house.

It must be able to power my house & charge from solar in a power cut.

I have tried SMA but it's requirements are way too expensive and it doesn't do what I want.

I'm holding off buying new solar panels until I know what the requirements of the inverter are.

I can fit 6 panels 2.4kw total with minimum 9amp, or 5 panels 3.2kw total with minimum 17.2amp (big panels).

While I'm here, I'd like to ask another question.

Some inverters require separate earthing from the house earth. Apparently this is due to some UK electric companies grounding neutral at some substations. Do I install an earth rod? Include the earth rod with all earths, mains and inverter? Keep separate the existing earths from the inverter's.

I'm hoping technology has rolled on to avoid this problem, but doubt it.

Thank you for your help.

Can you tell us a bit more of what your electrical loads may be (Watts Peak, WH or kWH per day, etc.)?

Any plans/ability for backup genset (petrol, diesel, natural gas, propane)?

And your rough location (Plymouth, UK?)?

More or less, a first planning, point, your 3.2 kWatt array would suggest a "maximum practical/useful" AC inverter of ~3.2 kWatt maximum for longer term off grid function.
