Perfect for use on a standby portable generator that doesn’t have wattage or amps meters. Updates once per second over Bluetooth so you can monitor your house load during a power failure. Most important, this provides amps per both 120v inputs so you can better balance loads and avoid generator from tripping both breakers off because only one side exceeded generator breaker rating. Also monitors voltage per each 120v side to also help you lower distortion by you balancing house loads across each 120v leg to reduce distortion and led flickering by managing voltages to be close to equal. A little pricey, but priceless in an outage to let you know how much stuff you can power up to the limit of your generator.
