I would like to monitor a generator that outputs 3 phase to a 200A panel. I only need to monitor the mains and I do not need to monitor individual circuits. Will a North American v4 IoTaWatt work for this application by enabling the derived 3 phase option or do I need to order the newer version with the additional reference voltage ports? I’d rather not use two AC reference transformers, finding a home to plug one into near the panel will already be a challenge.
Which CTs would you recommend for monitoring the 3 phase mains on a 200A panel?
