Hi All,
We have purchased a home that has a QCells system.
QHOME ESShYB-G2:
3 batteries: Q SAVE-g2
Q-VOLT hybrid inverter
Qcells is no longer in Australia, have been told mixed things about whether another inverter/ another inverter brand could be cross comparable with these batteries?
Hoping for help to determine what my options are if the inverter fails/ want to upgrade inverter but retain these batteries. Hoping it’s possible!
Any guidance appreciated.
Cheers
This is a high-voltage battery system (170 to 230V), which is quite common these days. There are several hybrid inverters, including Solax, which might be compatible with this battery. However, you will have to confirm that the battery uses the standard CANbus communication protocol.
Like many other solar panel manufacturers who have released energy storage systems, I suspect this system is just a rebranded version of a more common system made by a well-known brand, such as Solax, Goodwe, or similar.
Thanks for taking the time to respond.
I will reach out to Qcells and try confirm the protocol and do some research into solar and high voltage systems. Gives me some direction which is great!
This is what Qcells have informed me;
Qcells batteries communicate with the inverter through a built-in Battery Management System (BMS), using a digital connection such as RS485 and CAN. This allows the inverter to monitor the battery’s performance and safely manage charging and discharging. The system works together to ensure reliable operation and can also report data to the cloud for remote monitoring and support. Customers can monitor their system using the Q.OMMAND Home app or website.
Please see below for the technical specification:
I admit I do not understand what this means yet and need to research, I am presuming I need to understand if the extent the BMS used would prevent me from using another inverter?
Eg if I can use another inverter but just lose the ability to monitor in the same way?
Hi Matt I am in the same situation and believe that the only option is to replace with a new inverter and batteries.
Would you be open to buying or selling a battery so one of us could upgrade and the other add on?
