has anyone got any experience running a hybrid inverter and battery ac coupled with a victron inverter?
I do, and probably many others on this forum.
I was wondering how you have it setup? How do you stop the hybrid inverter dumping all its battery power back into the Victron side battery ? Do you have a ct with zero export?
I tested the functionality but I didn’t leave the system operating that way. I put the hybrid inverter into string inverter mode, removed the batteries, and used the Victron system for a hybrid inverter. The Victron software is much nicer than other brands so I have the Victron be the heart of the system and supplement with PV inverters when it makes sense. Sure, putting the other hybrid into zero export is one way to accomplish it. Just make sure the other inverter is capable of throttling back with frequency shifting and make sure you have the appropriate configuration set up on the Victron side to frequency shift when the batteries are getting full.
Ok, currently have a multiplus with pylontech batteries and a solis grid tied inverter ac coupled, frequency shifting all works as it should,
My pylontech’s are getting a bit old and rather than getting rid of them I was thinking of adding a hybrid inverter with new batteries but just thinking about how the two battery systems would work together
I’m running a system with
“old”: SolarEdge 10kVA 3 phase with DC coupled BYD LVS 10kW
“new”: 3xMP2 with DC coupled Pylontech US5000 (30kW) and various MPPT’s
Both systems are integrated into Home Assistant (HA) and I use HA to control the charging and discharging of the batteries. Typically, I put the BYD batteries into “preserve charge” mode and let them charge up occasionally to balance the cells.
Works well - after some tinkering
