Pete adds an extra Pylontech US2000B to his solar system and thought he might as well film it. Mixing the US2000B with US2000C Pete shows the configuration and how position in the sequence does matter. Please note that although only about 50V, this can source a lethal current, ensure you know what you are doing AND SWITCH OFF.

Ballancing is needed when expanding the pack. The instructions from Pylontech are "When parallel different SOC/Voltages of modult together, please maintain the system in idle for more than 15 mins or until the LEDs become similare (less than or equal 1 dot difference) before normal operation". In idle essentially means don't operate from the inverter - just disconnect comms cable before you do the power on sequence. BUT the ballancing condition is met without this faf if you charge/discharge the existing stack to 50% before installing the new module because it is suipplied at 50% - If you want to double check you can just power on and start the new module before installation to check the LEDs - just don't touch the dangerous bits!!.
