I know someone here is doing DIY power wall using 18650 battery, not sure how is their progress now.
I dont think powerwall is sold in lazada/shopee. All DIY.
My own power rack (not powerwall), i build using large square prismatic LFP cells(100AH and 400AH) instead. No time to test and group so many small 18650 3AH cells.
Cheap PWM charge controller only rm25.
Inverter will be more expensive especially those that can power up aircond's inductive load.
You can do away with the inverter if you are willing to convert your electrical system to DC, but it will be a really big project to cover whole house lor.
If someone plan to build a solar house then maybe they can consider adding DC ports.
If you want to play with DIY solar, you can start with replace garden light, car posh light etc. Those items are easily replace with DC equivalents.
Where do you source such parts from?I dont think powerwall is sold in lazada/shopee. All DIY.
