Inquiry about 48V DC generator set for base station NEW

I need to purchase two 48V DC generator sets (model ZF12/MC48-200) with Kohler KD477-2 engines for integration into a 48V LiFePO4 battery system at a base station. The generator will be controlled by an external battery management and energy management system, so I require the following technical capabilities: - Remote automatic start and stop via dry contacts or digital inputs. - Communication support: CAN bus, CAN J1939, RS485, or Modbus. - If CAN or RS485 is available, please provide the full communication protocol, register map, and technical manual. - Ability for the external BMS or energy management system to control the generator charging current (e.g., 50A, 100A, 150A, 200A) and DC charging voltage (approximately 48–59V). - Automatic reduction of charging current when instructed by the external BMS. Additionally, I need a silent enclosure for the units.
