Hello everyone,
my mobile installation has the following setup:
4x Victron 200Ah NG 25.6V batteries
Lynx Smart BMS 500 NG 4x Orion XS1400 (2x charging from the vehicle, 2x as a constant voltage source for 12V and 24V)
various SmartSolar Chargers
Quattro II 5kVA connected to shore power via AC1 IN
Smart Phoenix 5kV connected to AC2 IN of the Quattro
Ekrano GX
Both inverters are connected to the same battery bank.
The reason for this configuration is:
I need to be able to limit the shore power down to 6A. As far as I know, this isn’t possible with larger Quattros or parallel-connected MPIIs. Furthermore, standby power consumption is significantly higher with parallel systems. That’s why it’s cascaded with the Phoenix as support when needed.
The concept is that by default only the Quattro is active. If more than 5kVA is needed, the Phoenix should be manually activated and support the Quattro via PowerAssist. This works well so far. However, the Quattro then also wants to use AC2 IN to charge the battery, which of course doesn’t make sense. If I set the Quattro to Inverter Only, it no longer uses PowerAssist. The only option I’ve found so far is to set the maximum charging current for the Quattro to 0. However, this seems to only be possible via VE.Configure and not something you can quickly change on the go. Setting the charging current to 0 also means it won’t charge via AC1, even if that’s available.
Is there any way to configure the charging current for each AC input or to prevent the Quattro from using AC2 for charging?
Alternatively, is there an easier way to limit the charging current than via VE.Configure? Node-RED is installed on the Ekrano, but I haven’t found an option there either.
I know that the Phoenix can also be switched on via the relay and a wizard on the Quattro, but currently, manual switching is sufficient for me. However, I need to find a solution for the “charging loop.”
Any ideas?
