@derek-m that's true, but you no matter the battery size you will be limited to 3kw of power at peak - 16amp in EPS mode.
The goodwe inverter also has an EPS switch, but the battery discharge is 5kw Vs 3kw. Therefore I would personally explore a different brand, get more power and more battery capacity for less money.
As I keep saying, all these batteries are the same inside - you are paying for the name/branding.
12kW Midea ASHP - 8.4kw solar - 29kWh batteries
262m2 house in Hampshire
Current weather compensation: 47@-2 and 31@17

@kev-m Inverter is an inverter - so pop it on the wall. The batteries are 440 x 750 x 270 and you've probably stack two on top of each other or place them facing upwards.
You obviously need the batteries next to the inverter - so you'd need a cupboard sized space and you'd put the batteries on the floor.
This is my battery setup - I've since tidied up those earth leads
Would be a garage job for me, lots of space there and dry. Thanks.
