Re: Clarify: Radian GS4048a positive DC terminal mounting?

So this is a FlexPower panel, correct? If so, the Bat+ cable connected to the battery disconnect appears to be intended to attach to the battery +. The last doscument posted speaks to that. Finding the other end of that red cable may clear things up. (Don't hold your breath waiting for an OB staffer...

Re: Clarify: Radian GS4048a positive DC terminal mounting?

The 2D line drawing has a flattened perspective. Sort of like those ancient Egyptian hieroglyphs. I don't think ancient Egyptians were really flat, they just looked that way on Pyramid TV. Looking at the drawing and the photo, it looks like a Bat+ cable, and the FNDC b+ lead are installed to one pol...

Re: Prioritise PV vs Grid

This is how I prevent my inverter charger from charging my batteries unless they get very low or I want to manually turn on the inverter charger for a bulk or equalization charge. I set all my settings as desired, EXCEPT, I set the RE-BULK and RE-FLOAT to a low value, in my case 47.2 volts which my...

Re: Not selling, & inverter status says "SellRE"

OK. FWIW, my FM80s have GT mode enabled as well (to support Global Charger Control current limiting). Some other mechanism, in addition to GT mode, must trigger the transition to Bulk for selling. A 2nd example where the Absorb phase terminated in 1 minute. Is that because end amps were reached befo...

Re: Off grid with generator

OK. If strictly off grid, the "grid interactive" operating modes don't really apply, IME. I have my inverter operating mode set to "Support". You can certainly dive into AGS any time you want, but if the generator isn't performing properly with a manual start, it certainly won't ...

Re: Not selling, & inverter status says "SellRE"

Anyway, from event history it appears the system used the FNDC absorb time - absorb started at 1034, CPM @ 1044. This grid stuff makes my head hurt. I'd think Charged Parameters Met flag would be set whenever Charged Voltage, Charged Time, and Charged Return Amps are reached. However, with Automati...

Re: Off grid with generator

I don't use a Radian so am out of my lane here, but the AC Input (lower) line on the Mate is showing grid connection. The radian has two AC inputs - Gen and Grid. For an off grid installation, I'm not sure why Mini Grid would be selected as the Inverter operating mode. Is the system strictly off grid?

Re: Off grid with generator

I'm off grid, but don't use AGS.

Nonetheless, manual start should connect the generator and power house loads at the very least.

When the generator is started, look at the Mate. What is the LED on the AC INPUT key doing?

A passing reference to it. I had a detailed discussion on the subject in my PM, but have since lost it.

Not too long ago,I stumbled across a brief reference in one of the user manuals but failed to make note of it.

Re: Not selling, & inverter status says "SellRE"

Rebulk on the GVFXs is fixed at 25.0V. My system never went below 25.2V overnight, nor did it ever hit rebulk during the day. Current rebulk on VFXRs is set for 24.0V. After completing a charge cycle, Rebulk will subtract 1 minute from Absorb Time for every minute the battery is above the Rebulk vo...

Re: Not selling, & inverter status says "SellRE"

My charge controllers and inverters always had absorb set for 1 hour or more, but when I had the GVFXs the system never (daily cycles) took anywhere near an hour to meet charge parameters. Only time absorb went for an hour was after a grid outage. What was the Rebulk Voltage setting? If the battery...

Both Mates cannot be connected to the hub at the same time. However, the programming for the inverter, charge controllers, and FNDC are stored in those devices. When the new Mate3s is booted up, it will interrogate the devices, and collect their data. The only pieces missing will be Mate specific pr...

Re: Not selling, & inverter status says "SellRE"

That big Rolls battery was probably fine with a long Absorb Time even though it likely wasn't needed. Using the target ending amps will probably result in two changes, a shorter actual Absorb phase, and less periodic water replacement. I'd expect the system would get to selling sooner (if completing...
