Went to power up my parallel mp units and nothing first thought crap something drained my battery bank grabbed iPad checked shunt voltage is 26.44 double checked with multimeter same so I flipped on my 2 mpp2424mds running on the same bank and they powered right up so now I’m thinking what the heck is going on so I opened my laptop and tried to connect but it had drained its battery so checked the Bluetooth unit on the other mp and it did not give any data so having just done some additional wiring on the system on the output side maybe I screwed up so I double checked my work and all looks good so now back to the dc side checked class t fuses ok pulled front covers check at inverter 26.41 volts all good but will not power up on either unit so thinking I somehow bricked 2 units I figured I’d pull the comm cables and try to bring them up independently disconnecting from laptop did nothing so I pulled the coms from slave 1 which had the com cable to the master and a Bluetooth dongle and they powered up but with a error flashing so powered down reconnecting com cable to master and restarting units power up master on with green inverter light on slave 1 has the inverter on and the charger mains on (alternate green light) this is new shut down system and reconnecting dongle caused original problem any ideas on what has happened I’m confused ?
