I am using Flextime here so that we are only using Grid Zero mode from
2-6am, when there is no solar coming in. The rest of the time, the system
is in Grid tied mode so that we can take advantage of as much solar as
possible. But the battery bank is two strings of the NSB190 FT
Hello Dave,
Be sure you calibrate the flexnet and the inverter voltage. My gut feeling
is that the Delta voltage you have is too tight. If you have the system on
Optics, I'd set the LBCO pretty low, then observe how much voltage sag (or
where your voltage cliff is) you are getting at the
DaveWhat is the size of the battery bank and what is the typical load, let’s say at night or some other peak time? Bank size, SOC and demand can influence voltage. LBCO at 47.2 could be too high under smaller bank higher load situations. Also, with the AC coupled solar in an off grid case, what is
A minor update here. I had the grid zero DOD volts set to 48, and the low
battery cut out was set to 47.2v. But the homeowner told me that their
loads cut out at some point. Does anyone know whether it is possible that
Outback would be using a temperature compensated voltage for one of those
Maverick and Steve,
Thank you much for pointing me in the right direction here. I was looking
at the Radian setting and not the Mate3S settings. I've decided to use the
flextime schedule to have it go to grid zero mode at night when we will not
be exporting any solar power anyway. It really does
Yes, Grid Zero would work, but the customer wouldn't be selling power to
the utility. You could program the Radan to sell more power by lowering
the sell voltage. I would get aggressive with it for at least 20-30 cycles
to see if you can recover some capacity. Ideally, to recover lost capacity
You can do it in one of several easy ways.HPX mode on the Mate. High Battery transfer. When the battery voltage and/or SOC is above the setpoint drop the grid. When the battery voltage or state of charge goes below the setpoint pick up the grid. This case the Mate is doing the driving. Also
Hi All,
I have an AC coupled Radian that is used to back up certain loads when the
grid is down. It is paired with the Northstar Blue (Outback) batteries. The
system sits in float nearly all the time. During a recent grid outage, the
batteries had less than half the capacity that I would have
