Regarding the system configuration consisting of 2 x Quattro 48/15000 units operating in parallel, 4 x Victron Lithium 25.6V / 200Ah batteries (arranged as 2 series x 2 parallel for a total capacity of 51.2V / 400Ah), a VE.Bus BMS V1, an MPPT 100/20 charger, and a Fischer Panda 15000x Generator, the client's requirements include limiting both AC input currents to 16A, with the grid connection and generator operating at a maximum of 16A and 8000W (equivalent to 34A at 230V), respectively.
Question 1:
The Quattro AC input currents appear to be limited to a minimum of 28.5A, with attempts to set lower values automatically corrected to this threshold by the VE.Config system. Is this lower limit a hardware constraint inherent to the Quattro units? Are there alternative methods or configurations to achieve the desired 16A limitation? Additionally, could the VE.Bus BMS V1 be influencing these limitations?
Question 2:
The client seeks to cap the generator output at 8000W while allowing PowerAssist to function above this threshold. However, clarification is needed on the calculation and application of the boost factor. Existing documentation offers limited insight, suggesting further inquiry with Victron engineers. Could you elaborate on the boost factor calculation and recommend the appropriate value for implementation? Moreover, inconsistencies in PowerAssist activation have been observed, sometimes initiating for brief durations (2-3 seconds) or failing to engage within a 3-minute timeframe, resulting in the generator supplying 12kW, which is undesirable. How can we ensure the correct operation of PowerAssist?
Question 3:
The client requires a 230V AC to 48V lithium adaptive battery charger. However, the only 48V charger offered by Victron, the Skylla-TG, is incompatible with lithium batteries. Are there alternative charger options compatible with lithium batteries, or are there potential workarounds to adapt the Skylla-TG for lithium battery charging?
