For flying a small aircraft, is there any real benefit to having a fuel gauge or is the sound of the engine sputtering enough? 
If you're flying an ultralight you can always glide in for a landing.

Thanks again Gents. I will confirm the configuration on Monday when I get back, and respond to the above. Also, FlexNet Battery Ah was set to 2000 should be 500, reset and SOC is showing 100, for now.
When it restarts it sets SoC to 100%

two flexmax80s:
1. 4k PV and 12x 12V 100Ah AGM batteries in 48V config
2. 3k PV and 8x 12V 100Ah AGM batteries in 48V config

Just got the SOC below 60% alert
There's two separate battery banks and two separate Radians?

All of that is connected to a single Mate/FNDC?

Thanks. Checked those and were/are as you recommend. Charger AC Limit is set to 30AAC and can not be adjusted further up as default has been met. Coincidentally, On the GridZero parameters I have the DoD amps at 30 as well and also can not be adjusted further up on that screen. Just got a "Batt SOC...

Re: Only Charging o 50% SOC

Hi, I have a dual Radian Ac Coupled system with 2 8048s and a 12kwh blue ion cabinet . The cabinet is fed in parallel by the 2 radians. My batteries wont charge above 50% SOC.

Re: Can I use a PSX-240 Autotransformer to step up to run a well pump?

Hi, First time poster and a newbie here. I have a SunRun installed PV system with a backup storage battery (LG Chem RESU 10H SEG).

Re: Mate3 not recognizing new Flexmax 100

I was looking at the manual and it states the FM100 is not compatible with the Mate, Mate2, or Mate3. The Mate3s is required. The manual says on pg. 7, "This product is not intended for use with the previous MATE, MATE2, or MATE3 products." So it all depends on the meaning of "intended." Given that...

Re: Bypassing Solar

Trying to make sense of this, but with little luck. Almost looks like circuits are directly wired into the inverter circuit breakers rather than a distribution panel to the inverter bus bars? My guess is that lacking a wiring diagram, thecover needs to be pulled and everything traced. I had the PS4...

Hi. Here is a picture of my system taken when it was functional. Note that the DC disconnect panel I posted in my first post corresponds to the lower left in this picture. Based on their position relative to the inverters, I believe the panels on the left are AC panels, and by the same logic, the D...

Re: Too much potential?

What happens when a controller is overload depends on the controller design, and the nature of the overload. The controllers don't ignore a current overload, they have to deal with them. "Dumping" extra current in the form of heat is common. Too much can damage most controllers. Another scenario wou...

That's a good observation. A little detail from the above is that I can hit the FLA batteries with a good charge rate. But my discharge rate is really light. But you are still designing. It may not be a consideration depending on the battery type. I’ve pretty much settled on lithium iron phosphate ...

OK. I couldn't read the labels in the first picture from my phone. So those are AC circuits on the output side of the Inverter. All the AC circuits should have been wired into the bypass switch, but I'm guessing some were missed. Without a wiring diagram of the system 'as built', it will be difficul...
