I am trying to add Fronius Primo 3.0 to my EasySolar 3000 (multiplus). fimware “almost” all at update versions.
Primo will only output 350-600watts before throwing a 453 Error. It also causes flickering of lights. Primo version is 3.30.1.3 - almost latest release..
The 453 error suggests a hardware fault, my gut says it is a integration error..
Primo is set to MG50. Invertor has the PV control ESS installed. VenusOS (on rpi) sees the fronius..
Do you have grid? Can you check if the Fronius is running normally on grid?
This is an Of-grid system. No grid here :).
The Primo sustains the higher power (500-600w) when I’m also drawing that power elsewhere. I just noticed the power output at Victron fluctuates 223-244v As load stops exceeding power generated by the Primo.
Wondering if the MP simply isn’t absorbing the extra power quick enough, causing the V spike, in turn causing Primo protection to trip.
