MICRO-GRID-2

After spending considerable time trying various settings and operating strategies, I now have the inverter working, after a fashion.  Princeton Power has been only marginally helpful during the process, given that this is an old unit, out of warranty.  On thing they did tell me is that normally a 100kW inverter is connected to a battery bank of capacity around 200kW-hours.  My bank has capacity of only around 15kW-hours, or 7.5% of “normal”.  So I should expect some challenges. Knowing that my batteries were somewhat discharged, I decided to bring them to a full state of charge.  This would make my battery voltage as high as possible, and possibly avoid a low battery trip and allow the inverter to run.  Success!  The inverter locked into run mode!  Makes lots of interesting noises. Neither charging or discharging, the inverter claims a steady draw from the batteries of 4-5 amps.  Princeton says …

Experiences with the setup of a micro-grid at TBEIC

I have been engaged over the last 2 months with the setup of a small micro-grid at TBEIC, to be used for testing customer components that might be used in such grids. We have one customer who expects to test their intelligent breaker in a month or so using our setup. The three primary components that define our micro-grid are: – Powerhouse 25kW Load Bank, 480/3phase, load selectable in 5kW ranges, intended to represent a critical home or business power load that we do not wish to be disturbed when the utility grid fails. – Battery Bank for storage, includes safety, disconnect, and metering functions. Generously donated to us by a local firm who wishes to remain anonymous. The bank is made from 12 volt lead-acid batteries, 40 amp-hour rating, 32 total, about 1000 lbs of lead. Nominal bank voltage is 384 volts. Nominal storage is around 15 kW-hours. – …
