- 7Hello. I have a Smart solar mppt 100/20,also a Blue solar 100/15 with a Bluetooth ve direct dongle. Also aBmv 721 smart and a smart battery sense dongle. Is it possible with these components to get the regulators to synchronise as a master/slave to charge one 12v battery bank.
At the moment the blue controller goes into float mode very quickly and the smart controller seems to stay in absorption mode for a long time.. Also the blue controller wont come out of float until the voltage parameters are met leaving the smart controller still in absorption mode.
Any help would be appreciated and thanks for your time.
