my Multiplus-II GX, combined with 2 Pylontech US2000 (new) and an EM24 is configured as a grid tied ESS system (AC IN connected only). There's also a grid tied PV micro inverter (Hoymiles). The Multiplus II GX detected the batteries correctly. The Discharge Current Limit (Pylontech battery -> Parameters) is 50.0A.
The batteries are connected to the Multiplus-II GX via the supplied wires, there's a DC circuit breaker (80V 63A, CBI Electric QYD18U263B0) in the positive connection.
Today there was a higher load (baking oven), the Multiplus-II GX supplied power. The circuit breaker tripped, what surprised me. The Multiplus-II GX does not seem to obey the Discharge Current Limit. Is that the normal behavior?
If that's the case, why is there no Limit discharge current setting?
What's the maximum power the Multiplus-II GX will deliver (if there's demand) in a grid tied ESS configuration (AC IN connected only)? The peak power of 5500W?
So the workaround seems to be activate Limit inverter power and set the Maximum inverter power to 2000W?
(expected dissipation of about 200-250W and a safety margin; https://www.victronenergy.com/upload/documents/Output-rating-operating-temperature-and-efficiency.pdf)
I read that Victron recommends a 125A circuit breaker, but I want the Multiplus-II GX not to exceed the Discharge Current Limit of 50A (recommended by Pylontech).
Thanks in advance for your answers.
