Module interconnection

A project log for A 110 kWh Powerbucket

The lead-acid batteries of my off-grid solar system are dead. I will replace them by a 18650 batteries stack housed in a big wooden box.

The modules will be interconnected as shown here:

Thanks to the Weidmuller ZB35 bus bar clamp, module interconnection will be made easy. This clamp is perfectly suited to the 10x3 mm copper bars I use as collectors.

To remove a module, a 10 mm wrench will be sufficient.

The clamps will be directly soldered to the BMS pcb (in blue in the drawing).
