Possible surge loads of one or maybe several high loads cycling in very close time periods while charging batteries at the same time - 3kWh Wh...

Re: Charge Controllers remains in Bulk status

Agree, but I forgot to mention that the equalization was done yesterday around 12:30 pm. Also tonight is still charging the battery from grid (see attached file). This behavior is different compared before the equalization.

Charge Controllers remains in Bulk status

Hi, After doing an equalization, the charge controllers are behaving weird. This morning the controllers remained in Charged status and didn't produce solar energy.

Equalization

Hi, Today I performed a battery equalization. After more than 1.5 hrs the Mate3S shows 6 minutes remaining (for more than 30 minutes), the Flexnet light is green and blinking, one controller shows MPPT EQ, the other controller shows EQ Done. Is this behavior correct? I was expecting to see EQ don on...

Device map

Hi,
Looking at my device map, shows "3 devices looking" good but my system has 6 devices. All six devices has a green checkmark. I think in the past showed "6 devices looking good".
This could be a bug in Optics?

VFXR3648A DoD amps

Hi,
I need guidance in how to set up DoD amps in my system for Grid Zero. I read the FXR operator manual but still I don't understand how to calculate the right size. Any help is welcomed.
