The first video there is actually recorded coming back up river from Steveston. You can tell because we are having to use from left to right in the video 49 amps for the port motor/generator 49amps for the starboard motor/generator and we had on the last shunt gauge some inbound solar power to offset the 100amp current draw of the tow motors like around 17 amps or something.
The wind was blowing back up the river and even though we have a very low profile we are going to be taking a more serious approach to the wind in the future and will be acquiring a wind instrument.
The other gauge on the bottom row reads voltage and any inbound charge current from the two shore battery chargers obviously disconnected. All the top readings on the gauges measure voltage. When the system is disconnected via the contactor disconnect switch on the bottom right panel the top right voltage gauge will display the voltage open circuit of the solar array.
We have port and starboard generators wired to the shunts and could effectively drive the boat utilizing gasoline power if necessary as each of the generators will make 60amps but in this case we did not need to. So from a voltage perspective in the first video you can see we are sitting at 51.2 volts. In our case we need not worry about a low voltage situation until under 49 volts. We had still over 50 volts when we tied off at the slip.
