On a recent installation Victron Smart batteries are being charged by Victron MMPT solar controllers and a Balmar alternator though a Cyrix Li-Charge 230, the latter is controlled by a VE Bus BMS. This is an installation exactly as per the schematic diagram supplied by Victron.
The problem is that the Cyrix Li-Charge is opening, (disconnecting) the battery almost exactly every 60 minutes for a few seconds then closing again. This is causing significant problems for the Balmar alternator regulator.
My understanding is that the Cyrix needs 13.7V on the charge terminal in order to close. The only way I can see this working is if any charging source is set to a minimum float voltage of 13.7 which according to the Victron charging recommendations for their LFPs is too high.
It is worth mentioning that the charge connect circuit from the BMS is always high, as it should be under normal operation.
On another installation I have done I have used a Battery Protect as the HV disconnect device but I gather this is not now recommended.
What is the solution to this dilemma? It is not acceptable for the Cyrix Li-Charge to open every 60 minutes when the charging sources drop into float mode.
