Tried searching for previous discussion on this but perhaps I'm using the wrong search terms.
Recently I purchased a portable power station for my wife's business as she is a musician and often needs to run her PA with no mains power available. I was really impressed by the quality and price of the new Lifepo4 portable power stations. It got me thinking about my own home power set up.
I currently have a 7kw system mains connected on my home. I've been considering a battery but the large upfront cost might be hard to get signed off the with wife.
I work on software and one general theme of the last 6 or 7 years is the migration of monolithic to microservice architecture. Where large platforms that speak to most of the broader system are being replaced with purpose built distributed microservice. The advantages of this approach include the following:
- easier to test, POC, and implement MVP
- dedicated specialisation and sizing for the task
- easier to scale
- easier to decomission
- greater flexibility in vendor negotiation
When I think about this with respect to battieres in the home I wonder if I should consider independent batteries in my home in the appliance groups I need them. I.e:
- kitchen group (oven, fridge, dishwasher)
- living room (tv, lamps, router)
- laundry (washing machine, dryer, heatpump hot water).
The rest of the house can run off mains as the remaining draw is minimal.
Pros and cons of this approach vs a single battery connected to my house-wide fusebox:
Pros:
- lower unit cost allowing me to take phased roll-out approach
- modular design means upgrading certain parts can be provider and type agnostic
- plug and play design using wall plugs and networked switches for load shifting
- portability of batteries as stand alone power stations. I could take them with me or use for other things.
- local DC current available for appliances that can use it rather than losing efficiency when converting to AC.
- less insurance liability (when DIY) as no house wiring needs to be changed.
- ability to have isolated redundancy for critical systems like fridge. In other words your kids can leave a resistance heater on and drain all power for critical systems overnight.
Cons:
- likely a higher cost per Kilowatt hour as the cells would be purchased in smaller amounts.
- 3x cost of (BMS, case, inverter etc). Albeit smaller
- less ideal ability to monitor the group in aggregate (though I suspect I could overcome this with the right power stations).
Interested to hear the communitie's thoughts on this
