I am running a 24v DC system with a 240 - 24v power supply and wish to add a Bluesmart to maintain the battery bank properly and give the system black start capability, a couple of questions: can the bluesmart operate as a power supply if the battery bank is switched off without interruption or does it drop supply then re power the loads. are there any concerns with the parallel sources, I am totally comfortable with the two supplies in parallel but the customer wants to hear it from the manufacturer
