hello
this is my system witch is not the most simple !
i used somme old panel , my homme is in the forest so it’s not easy to found some place with full sun and my roof is not the most easy to!
i have 2 mppt 150/35, one mptt rs450/100, one fornius galvo 1.5, one multiplus II 5kVA, a victron battery bank 330Ah with a lynx bms and a EV charging station. i added one orion 48/24 for my water pump, one orion 48/12 for my internet box and a gx tank for my tank level.
as it’s a test and training system i often make some modification so there’s some cable witch could be organise beter
the protection was disign after discussions with the consuel (french control organisation) to ensure that the system complies with legislation
i used this systeme for testing beta firmware,for node red and modbus demonstation, and for training to show the different possibilité of the victron systeme !
all line connected to the dc bus need to be cut and protect (- and +) so you can used breaker or fused witch switch but you need to resp.ect the max Icu and most of time, a mega fuse is not enough.
in my case i use schneider breaker 20kA !
Thanks. I think it is well known that the Mega fuses are not suitable for LIFePO4 batteries. In my case I have class T fuses (only +), which are suitable for the Icu.
@thierry_cortassa you wrote “all line connected to the dc bus need to be cut and protect (- and +)”. Is this applicable for the battery and PV or only battery or only PV?
both, but the battery switch and pv switch are considered as emergency disconnections and must therefore be accessible. The other disconnections may be at the back of a cupboard for exemple !
