Re: FW1.5.11 TOU Schedule

Well it looks like my Skybox is working properly with the new firmware, as regards TOU operation. I've set it up to switch to battery at night (after 6:30 pm) until 0900 the next day, and that's exactly how it worked last night. Etn, if you've tried reprogramming TOU, make sure your first time inter...

The GVFX's will not accept anything but a high quality AC source. If it's not an inverter generator it won't connect.

Re: FM 80 firmware

If it's any help, the FM80 I purchased earlier this year (2020) has firmware version 3.3.0.

Also, your best bet for protecting your new batteries is to use the FlexnetDC auxiliary contact. The FNDC voltage measurement is much more accurate than the FM80 for your purpose.

Re: Need some help here.

I don't know how your system is wired but typically the FNDC battery voltage sensing wires are connected at the battery, for best accuracy. Again, if batteries were changed out that's where I'd be looking. Here's an excerpt from the FNDC manual: https://drive.google.com/file/d/1sV5sbc8Tb0bmpfg1G9eSY...

Since the batteries were changed, make sure the FNDC's battery voltage sensing wires are connected at the new battery's positive and negative terminals.

Re: radian 8048

If you're using Simpliphi 48V 3.8 phi batteries, this calculator https://simpliphipower.com/support/system-based-phi-battery-calculator/ indicates 5 batteries is the right size for that inverter (5×75Ah/battery=375Ah), so you're in the ballpark. I think battery size may be somewhat dependent on your...

Re: Optics RE readings not matching up with Meter Readings

My understanding is that the "To Grid" data on Optics RE represents only the power that goes from the inverter that is sold back to the grid. It does not include power going to any other place, such as batteries, or the load to power appliances on the property.  These systems have no way of knowing...

Re: Westinghouse WGen9500DF Dual Fuel Portable Generator

No. The key fob start is for starting the generator from a distance, just as you use a key fob to lock and unlock your car from a distance. You could do this but you'd have to leave the generator connected to Skybox all the time and it would be manual start only, not via AGS. In order to use the Sky...

Raysun mentioned float coordination in an earlier post. I think it might be worthwhile for you to try enabling it (if it's not already) to see if that keeps all your chargers working together.

Re-Bulk Voltage is at the Default: 48 VDC
Since your battery only got down to 49 volts your inverter never reached the rebulk setting. If you want it to charge from grid when battery gets down to 49 volts the rebulk must be at least 49 volts.
