Use where Inverter cannot Bleed-Down Caps in 30sec. MNBLEEDER
MidNite Solar Little Shut-Off Box system
Not all grid tie Inverters meet the 30V in 30 second rule. The Bleed down unit fixes that problem for those Inverters that require this time and voltage requirement.For Inverters that require a bleed down time and voltage requirement.
The MNBLEEDER is an outdoor enclosure that has one MNLSOB-T1-AC transmitter and will also bleed down the capacitors in many grid tie inverters. This may be needed to reduce the voltage in the PV output circuit fast enough to meet the NEC 2017 requirement of <30 volts within 30 seconds. The MNBLEEDER will work with one or two PV output circuits and is rated for PV circuits up to 1000 VDC and 12 A each. It does require a 90 volt to 300 volt AC source which is also the trigger for rapid shutdown.
