Hello, I'm experiencing a very odd behaviour of my Skylla-i charger and nothing seems to help.
I got a replacement Skylla from Victron as the assumption was that my Skylla was defective. Now I'm again experiencing such problems.
I have made sure that all configurations and settings are correct. I have spent a lot of time going through the manuals of each of my system components and nothing explains this behaviour.
I have resorted to using a separate controllable power supply for charging the batteries at this point.
This happens quite often:
Skylla outputs voltage, but not current. I have read all of the datasheets and manuals of the used Victron devices and couldn't figure out what could be wrong. Sometimes Skylla wouldn't charge the batteries even when the battery voltage is at 24V. Sometimes it wouldn't charge at 25.6V.
Sometimes when disconnecting battery negatives from the system overnight and then re-connecting them, Skylla would suddenly start charging my batteries.
I have tried connecting Skylla directly to the batteries, removing all other system parts and it still wouldn't work. Then it sometimes would work again.
Is it possible that the batteries communicate with Skylla somehow? Like over the Vbat+ wires?
My setup:
2x Victron (LiFePO4) Lithium batteries 25.6V/200Ah in parallel.
1x SmallBMS connected to the batteries and controlling the relays (low voltage shutdown and charge relay activation).
1x Skylla-i charger 24/80 (1+1).
1x BMV702 - for SOC, current and battery voltage measurements.
1x CerboGX connected to BMV and Skylla.
I appreciate any kind of help that could solve my issue or better explain the situation.
