Hi to the all members of this amazing community.
I would need to know please if I can connect 2 Smart Battery Protect SMP 220A in parallel.
I need to drain up to 250A from my battery Bank. Occasionally with peaks of 400A. So it is not possible to go through a single 220A SMP, although I could connect 2 of them in parallel, but I don`t know if it is feasible.
Thank you in advance for your support.
Im not sure if this is possible, it should be, but at the very least its not supported by victron.
However, i have succesfully used Kissling 30series (30-311-12/30-511-12) relays in the past. You can get them in all sorts of configs, ive used monostable (the contact is closed as long as theres voltage on the control cable) 300A to switch 24VDC and bistable (it needs a pulse to switch on and another to switch off, kind of like a remote battery disconnect, the coil uses no current in either state, only for the switching) 500A.They are chonkers, but IP67 and also available with magnetic blow out on the contacts for voltages above 40VDC. Ive used them to disconnect load from Lifepo and as a remote battery disconnect, the starting current of an 18l engine goes over the 500A. Even the NO/NC variant has both contacts rated at the full current
