What “Dry-Run Protection on Solar Pump Inverters” means on an RFQ
Dry-run protection is a trip philosophy: minimum-power detect, flow/pressure switch, or both — decide before you quote BR500-P / BR600-P macros.
RFQ data that locks voltage and power class
RFQ must state probe type (float, flow, underload current) and whether the pump may restart automatically after water returns.
Control functions that change field behaviour
Enable dry-run / underload and a restart delay that matches well recovery time; do not leave only a thermal overload as “protection”.
Site, EMC and protection notes
Borehole and surface sites both need the probe cable protected from sun and rodents; sealed glands matter as much as the IP rating on the drive.
How Boray series map to this topic
Map to BR500-P / BR600-P pump macros first; FS300 if the same site also needs constant-pressure PID on a grid-fed booster.
