Yeah I'm not an electrician, and unless you are one I'd say you should probably have one install it for you if you want it to feed directly into your home circuit.
There's a few other components to it though, like an inverter basically takes the DC output from the batteries and converts it to AC at the right specs for your home circuit. So really you just need that to be installed properly, and then I'm pretty sure the batteries are plug-and-play.
Also an MPPT is important for solar batteries because it controls the flow from the panel to the batteries, which improves efficiency as well as battery health and safety.
The smaller modular batteries though, they can be rated for over 3500W continuous output. That should be enough for a heat pump, especially because I'm pretty sure that's for each battery.
But if you're running stuff from outlets, you can also look into portable batteries, sometimes called power stations. Some of them come with built-in inverters and MPPT controllers so you can charge them with solar panels and run AC devices on them without any additional peripherals.
