Hello i have a question about using parallel victron solar charge regulators in large pv system (20kw) with one battery bank. is there any commercial equipment for the battery discharge protection or management since the regulator control only the charge of the battery
As you have not mentioned the battery type I am presuming lithium Lipo
There are BMS control systems that monitor the the battery cells and thus can alarm when one cells goes low or high or over them.
one such system is 123smart https://123electric.eu/
Hello
Thanks you for your response
my question is about the discharge protection of the battery banc since victron energy have solar charge regulator that can be used in paralelle in large pv system when charging only one batery banc
the loads are not connected to the solar charge regulator (since it is not equiped with this type of input for big power rating )
the battery type is not mentioned it can be lithium or othe type
but my question is not only the battery monitor but also the equipement used to cut the connection betwen the battery and the loads to protect the battery and agin reconnect the battery to the loads once the battery have been charged
is there any commerciale equipement to do that (victron or other )
Thanks again
best regards
How about a Battery Protect? You'll just to have nominate one charge controller to activate the relay. (Or use a battery monitor such as a BMV712)

Hello
Thank you very much for your response
i think the victron battery protect is the most interesting
but , neverthless , it is limted in voltage and current , (48v/100A) , so it will not be the best solution for large pv system (about 20kw pv)
i wonder if it exist another commericale solution , or the installer have to set up a costumezied system for disconectong the loads once the battery discharged ?
Best regards
