It basically has a hard set limit of 5000w for the 6000w generator, calculates when the correct moment to start the batteries to have them charged at 9pm, then shuts off the genset if the batteries go into absorption mode.
Still testing… but it all makes me think there would be an easier way. Plus, if anyone is listening that can make these changes, the inverter had better control than the venusos, it would start on voltage and stop on absorption. Moreover, a “charge the batteries with the generator” button manual mode would be awesome.
