Upgrading to Pylontech 3000c


Recommended Posts

Hi guys , hoping someone could offer some help.

Currently have 2 Axpert 5ka (MKSII) in parallel. 6 Canadian solar panels on the roof(but seldom turn the solar on now because of error 72 which does not seem to go away).

I have a BMV 702 for monitoring and looking into getting ICC as well.

I only have 4 200ah Gel 12v batteries connected and use this just as a back up during load shedding. 

My setup has fuses for batteries and solar.

50mm2 battery cables running to each inverter from the battery fuse.


I'm looking at removing the 4 gel batteries and upgrading to 2 x Pylontech 3000c.

So far my shopping list includes

1. Pylontech batteries x 2

2. Pylontech cabinet

3. ?Spare pylontech battery cables


Would I be able to link the 2 pylontech batteries in parallel and connect it to the battery fuse box , or will the battery fuse box cables need to be changed?
