Auto Grid-Tie is disabled
I have multiple systems running same configuration with no issues.

It is anomalous data as it shows selling 2x the battery capacity with no change in V. What the cause is, I do not know.

Re: The Right Way to Ground

Turns out my well is actually plastic I guess? For most wells the top 20-30 feet in our area is steel, with newer wells using PVC casing below that. They used to use PVC cement to bond the sections, but that creates some excitement when a spark ignites the contained vapors. Our local well driller, ...

Re: Issues with Grid Tie and Time of Use

Anybody have any insight on why the heck it looks like the system dumping a boat load of power back into the grid at midnight but the battery level doesn’t change and obviously no solar... I generator either. I’m baffled. Started showing this 3 nights in a row.... Check your firmware level on the M...

Re: Bypass 600v Ground Fault fuse

So if the array is on a structure, you want to be careful given your remote location. The fuse is for the Ground Fault portion ...

Its more than enough to drive the charge controller and charge the battery to 60V if specs call for it. @raysun, unfortunately it is a 24V inverter.

Re: Issues with Grid Tie and Time of Use

Are you using FLEXtime tab on the Mate3s to change the Radian's operating modes? If so what modes are you using? Should be Grid-Tied during non-peak charge period and Mini-Grid or GridZero during peak periods. On the Mate3s Global Charge tab, make sure to disable "Auto Grid Tie Control." I...

Re: Outback communication cables

...the conductor is not copper. For comparation I took the picture next to a proper CAT6 shielded cable.

Re: Questions about Flexmax 100 screen on Mate3s

Your picture is of the FNDC's Relay tab. Nothing to do with your FM100s. My guess is that you are not using the FNDC relay and can ignore the yellow boxes or change them to the default values.

Thats good to know. Someone should tell Outback. They wire the FlexPower panels with those breakers and bare wire. Granted, it isn't that fine welding wire, but cable made from what looks like 18GA strands. What tool do you recommend for 2/0 ferrules? I know that Outback uses ferrules on the pre-wi...

Re: Off Set Enable Question.

Then as the chargers complete their times, they can go into a SILENT mode in which case no PV is harvested in the bright sunshine. This SILENT mode as I understand it is the period of the timer being completed and then the voltage drop from ABSORB to FLOAT and FLOAT to RE-BULK or RE-FLOAT. The 3 ch...

Re: Parts Support for GS8048 after fan failures

I have seen reports of issues with that PCB assembly on the original Radians. Your right fan is only going to come on when the temps of the components are high enough to require the fan. It could be during your test, that the power being inverted did not require the right module or not enough power ...

Re: Aux fans keep dying?

This is setup as 'vent fan' to vent the battery when the voltage reaches a certain level. (I think it is set to around 54v but I am away and cant double check) Set your voltage to 56.8V as this is approximately the voltage at which the batteries will start off-gassing hydrogen. At 54V your fans are...

I put a system that matches your 8048A and Mate3s into Minigrid from 4pm to 8pm and Grid-Tied with offset the remainder of time. It is also on OpticsRE. If I forget to update you in a couple of days, send me a PM.

Re: Power outage...

from the comments I assume a 90ADC breaker and 2 gauge wire would be optimal. Hi Peter, your 4 gauge wire is adequate. Considering your use profile of only occasionally getting to 80+ amps, it is more than adequate. What is optimal is always a question of the cost/benefit ratio. A 2 gauge will give...
