2.4kWh is the energy capacity. 1.2kW is the output power.

I would and do set mine to 100% charge and discharge and on grid discharge limit of 10% which gives you the 90% dod.
I totally understand what I mean about sending to grid, I sent about 2000kwh to grid last year.
This year I will be getting a thermal store to soak up as much as possible, as certainly in mid summer, there is just not enough batteries to soak up all the solarWest central Scotland

I would like to use something that powers my radiators in an effective way. and provides hot water for showers without needing to obtain grid power to do that (i only have Oil for my central heating and its so expensive right now that the local provider didnt even give me a price yet other than they dropped off 500ltrs of oil as i needed it but now im thinking its gonna cost a lot of money £1 a ltre maybe ?)
I have looked at the mixergy as a hot water tank replacement as it seems to be efficient and solar compatible so it might help with providing a least cost effective hot water and I can finally get rid of my electric shower and existing hot water tank that uses electric and Oil power——-

I'm hearing from friends in the South East of England that they are paying between £1.60 and £2.30 a litre for oil, so I think £1/litre may be optimistic I'm afraid 😨
Mixergy seems a clever solution, but my problem with mixergy and indeed hot water tanks in general is that you have a large body of water of which the majority is largely stagnant, and I'm not a fan of that.
If its an unvented cylinder you need a pressure inspection every year, if its an vented cylinder, your water pressure is gonna be pretty rubbish.
Thermal store means mains pressure hot water, ideal for a strong shower, or fast filling of a kids paddling pool.
Take the lid of your toilet cistern in Scotland and you see a black band around the water mark, that's all the bugs in the water that have died and floated to the top. Not great.
The bonus of a thermal store is that all the water you run through it for showering and washing hands, or brushing sensitive teeth only ever runs through a copper coil, so it's never stagnant, the mass of water in the tank is seen as dirty water which heats the coil the potable water runs through, so there is a physical barrier between the mucky stagnant water and the clean water that you use.
Something like a coil just at the top of the tank controlled by a mixergy type system would be ideal imo, but no-one seems to make one of those.West central Scotland

Sorry missed the other bit.
I do have a smart meter and am planning to use my cheaper period to heat the thermal store in winter time and have the central heating water then heated with a heat exchanger off the thermal store.
Batteries are great, but you will find next month (April and September are our brightest months) that your batteries will be full and you still send some to the grid, whereas if you could divert some of that to your hot water tank /thermal store then you save the cost of heating the water.
On the flip side in winter you won't have enough to fill the batteries,so definitely not enough to heat the tank, but thats where the cheaper rate of octopus comes in for those of us with a smart meterWest central Scotland

Since you already have an electric heated hot water tank, id suggest looking at solar diverters.
If I already had a tank I wouldn't be looking at thermal storesWest central Scotland
