First trip with our complete electrical system

The system, as I've built it over the last 6 months:
2 200 watt flexible solar panels
Renogy 30 amp MPPT charge controller w/ Bluetooth

2 100 AH BattelBorn lithium batteries
Xantrex Freedom XC 200 watt pure sine wave inverter/charger
Victron Battery Monitor with Bluetooth

Everything worked great. Early spring sun wasn't enough to put a lot of charge in the batteries after being down 100 AH over night and early morning, but they kept up with the day use and put some charge back in.

It's pretty cool to to see the output for the 2 panels in series, and the see the step-up in current and reduction in voltage that the MPPT charger does, compared to 25 years ago with 100 watts of panels and a PWM controller.

It's freaky the first time to see 147 amps streaming out of the batteries when the microwave is on.

As one who, in the past fretting with the interminable time it took to put 100 AH back into flooded batteries, it's equally freaky to start the generator, and see the Xantrex pumping 103 amps back into the batteries, giving a full charge (100AH replaced) in an hour.
