Hope you can help me on my below inquiry.
We now have an ongoing commissioning of our 16.5kWp 15kVa 27.5kWH system, below are the list of components we used:
a) Multiplus 48/5000/70 : 3 units
Upon reading the notes/references/guidelines from Victron site, i have some clarifications on our installation. I've listed below my 1 set of inquiries:
2) Do i need to wire for Allow to charge and allow to discharge from BYD to Inverter/charger (not familiar on the setup) can you assist me on this ? do i still to add an assistant aside from ESS? so that the BMU has a control on charging and discharging coming from the MPPT.
3) After paralleling the 3 Multis ( using VE bus quick configure), after turning the BYD batteries the system won't start up. But if the inverters were not connected in parallel , system is up and running. Beeping alarm on the BMU 4X see attached screenshot.
