Hi Jay,
The system feeds the grid through an SMA H-FUS inverter. The Outbacks
are off grid inverters, but are AC coupled to the batteries to provide
power when the grid is down.
The inverters monitor the batteries and go into REFLOAT when the
batteries hit 25 volts. I would like the inverters to go strait into the
ABSORB cycle instead of going to REFLOAT.
The grid tie came after the the Outbacks were already in as a backup
system.
Thank you,
Drake

Hi drake.
You're talking about the inverters charging the battereis, meaning
this is a grid connected system?
Do you have a mate3/s or 1?

Hello Wrenches,
We have a rental property with two, stacked VFX 3524 inverters. In the
winter the batteries don't get an adequate solar charge. I would like
to have the batteries get a bulk charge when the voltage drops to 24
volts, but it keeps hitting refloat.
How do I disable refloat? Can I just set the refloat time to zero?
Thank you,
Drake
