Most of the time a DIY powerwall will be lithium-ion, but the charge controllers will support several battery chemistries so it's important to make sure your charge controller is set to the right one before attaching it to your battery. Another thing to check for is the current setting.
You now have a UPS providing battery backup. Inverter is single phase 120VAC. You can use half the sub panel. You can wire to both legs of the sub panel. You can install a 120/240V transformer. You can install a manually interlocked backfeed breaker. Main panel feeds 125A to the 125A main breaker in sub panel.
Arrange the cells in a configuration that suits your load requirements. Weld or Attach Cells Weld or attach the cells to each other to form a battery pack. Add the Battery Management System (BMS) Attach the BMS to the battery pack to monitor and manage the battery's health and performance.
Main panel feeds 125A to the 125A main breaker in sub panel. Next to that is a 30A breaker (fed by inverter), and sheet metal interlock prevents both from being on at the same time. "can you run output from the inverter to the subpanel while it has input power from the main panel?" Run to a breaker which is off (and interlocked).
Add the Battery Management System (BMS) Attach the BMS to the battery pack to monitor and manage the battery's health and performance. Attach Connectors and Wrap the Battery Connect the charge and discharge connectors to the battery. Securely wrap the battery pack to ensure it is protected. Connect BMS to Inverter Input
Now that you have determined your energy needs, you can choose the appropriate size of the battery bank. A larger battery bank will provide more power storage and longer run-time, but it will also be more expensive and take up more space. Therefore, it is essential to strike a balance between your energy needs and the size of the battery bank.
How to Install Solar Panels — Charlie DIYte

Let''s Learn About Super Capacitors! (A Practical Guide to Super ...
The 9v 300mA MAX solar panel is charging a set of three super series super capacitors. The 1N5819 diode blocks power from entering back through the solar panel. The charge off the super capacitors enters into a 3v regulator that powers the load (Load circuit not seen here). When using solar panels, you don''t necessarily have to limit the charge ...
75/15 mppt charge controller panel sizing
Generally it is safe to charge most AGM batteries with a current of up to 20% of their C20 capacity/AH rating, so ~20A max for a 100AH battery bank. Your MPPT charger having a 15A …
Critical Loads Panel Install (Extending Existing Circuits)
Here is an easier way to do it: Make the former main panel a subpanel/critical loads panel and remove any N-G bond. Install a new panel and it becomes the main panel. Install a transfer switch, can be 2 pole depending on inverter and how N-G bond will be done, but I prefer a 3 pole so neutral can be switched and inverters bypassed ...
