I have added a second multiplus 24v 70a 230v device in parallel to an existing multiplus.
I was expecting to see at least 100+ amps of charging when in parallel.
1 / Both devices are the same
2 / Both devices have the latest firmware
3 / Both devices are set up in to run in a Master and Slave configuration
4 / They are charging two Victron Lithium batteries (2 x 200AH 24v)
5 / The system delivers the correct passthrough current (now 32 amps)
6 / Inversion works at full capacity 5K+
7 / All settings are set to max charging 70a each (140a total)
8 / The original single multiplus delivered 60amps continuous charging from 50% to 99% seamlessly
9 / Tests have been run when all devices are cool
The two together will not deliver more than 77 amps in parallel. While I don't expect it to deliver 140amps I would have expected at least 100+. Lithium technology is capable of accepting more current than this. I added the second unit to help increase charging capacity as well as inversion capability
Can anyone shed any light on why this is happening.
Thanks in advance
