We are trying to use a BMV 700H as current and voltage transducer for a PV system directly powering air conditioners, i.e. in a system without batteries. Someone told me that would work together with a CCGX for remote monitoring of that system, which sounded feasible. But for some reason, the BMV does not power up and do not provide any signals. Is there a fundamental difference between connecting them to a battery system and a direct PV system respectively?
The PV array is a series connected array with 8 pcs 275W panels connected in series, delivering a voltage in the range of 240-275VDC and a maximum current in this application of approximately 4-5ADC.
