I am working on a project with a customer who wants to have 2 x Smart Battery protect 48V-100 in parallel because his solar panel MPPT load is higher than the 100A capacity of the switch. The MPPT's are not Victron and cannot be controlled with a GX product to stop the charge if required. Each Switch input is going to separate MPPT controllers group, the output connected th the BMS Load side bus.
The BMS only has one normally open contact output used as an Allow to charge signal. We normally use this contact to drive the Remote Signal of the Protection relay. In this case can we drive both remote signal with a single contact and in effect paralleling the two control circuits or do we have to use a relay with multiple sets of contacts?
