Re: help with 1-line diagram

Adding a 100A disconnect between charge controller and battery is clearly called for. Since the FM100 has built-in arc fault protection, it need not be anything other than a standard 100A DC panel mount breaker. TBH, if there's room in the DC panel to mount another breaker, it will be faster, cheap...

Re: help with 1-line diagram

My take. Everything looks good, with the exception of missing disconnect means between FM100 and batteries. What I recommend is remove the existing breaker that I highlighted and place it between FM100 and batteries. You do not have to physically move the breaker, of course. Just modify the connecti...

Re: VFX2812 Limiting Charging Current?

It is configured to limit AC current to 14A for charging (the maximum) and my current AC input voltage is 108V(this marina is a little low). That should mean that I have about 108A DC that could be given to the batteries if I am charging to 14V. For some reason I am only seeing 40A. The ambient tem...

Re: Shunts & SOC

The shunt readings are showing correct readings. When the shunt on inverter shows positive reading, it means the inverting is charging the battery. When the shunt for the CCs shows negative reading, that means none of the CCs are doing any charge and just showing the idle current consumed by the CCs.

Re: Re-try autostart when genny is cold (second time works, can it be programmed?)

I am confused. Where does Outback gear comes into play in your issues? If you are using AGS on the MATE, the Gen turn ON signal is a constant 12VDC from the AUX output of the inverter. The Gen stop signal is when the AUX output becomes 0VDC.So I'm not clear on your first try and second try situation.

Re: 3 phase stacking GSLC's

Your description of the Multi Phase Coordination feature admits that Outback knows the system should reject incomplete (2 of 3 phases) external AC input, because it would be dangerous to connected equipment to pass that electricity on. In the same way, the inverters shouldn't CREATE incomplete thre...

Re: 3 phase stacking GSLC's

I don't think so on the 4th though. Multi Phase Coordination, at least in the quick setup guide I found a reference to it in, refers to the inverters working together to reject a flawed external 3 ph source. This capability indicates that Outback realizes it's a problem to pass thru an incomplete 3...

Re: Need an advice to select GS4048 or GS8048

What is the brand of your GT inverter? One thing you need to ask around is if your kind of GT inverter plays well with a Radian(GS) inverter. The other thing is, one of the requirements is the Outback inverter must be of higher capacity than the GT inverter. In their application note example,Radian ...

Re: 3 phase stacking GSLC's

Last I heard, the 110v versions of the vfx (I think) and Radian (I'm pretty sure) can't be configured in a three phase stack, so if that's true then your case isn't supported anyway. Either way, "keep supplying partial 3 phase power" should DEFINITELY not be the only way, and shouldn't even be the ...

Jason, this is a reply to your 1:11 pm post. I may have not described my DC connections very clear. The negative and positive bus are actually both have common connections, with the difference that the battery breakers are in the positive cables. The basic GSLC usually comes with 2 shunts, one for C...

Re: 3 phase stacking GSLC's

The safe and official way to connect the DC busses is, from battery bank, run one separate positive cable in series with a breaker to each GSLC. Yes, your negative can be common, and without a breaker. Run one cable to "phase A" GSLC, then make jumper cable to "phase B" GSLC, and another jumper cabl...

Re: Stacking - Other options?

Is there a specific reason to prevent the downstream inverter from back feeding its surplus production to the upstream Radian? Seems to me that the upstream Radian might make use of that surplus power to charge its batteries. Is it because the upstream Radian may not be able to use the power and th...

Yes, Kurt's solution is the best and the "by the book" solution. But if @bear really wants to experiment, the concerns aired can be mitigated, I think. To avoid selling by the downstream inverter, set the sell voltage to an unreal/unreachable voltage, like 60V, or the sell current to 0A, for double ...

Re: Stacking - Other options?

I am rethinking my earlier opinion. I think that set-up where the output of one Radian goes to the AC In of the second Radian is a little more complicated than I thought. We want them to share the load equally, just like 2 paralleled generators, but what if the recipient Radian goes pass-thru? That ...

xxxxxx...If the first option is not possible, then can the one's output act as the grid input for the second? Yes, that should safely work. Once the recipient Radian accepts the other Radian's AC input, you theoretically ties in the AC out (load). The load fed to either Radian is now being fed to b...

Re: Battery Test Procedures, RE800

With 4000w of DC load plus the initial 100W, that seems a lot to handle for your battery bank. It should draw 70+Amps and in no time will bring down the battery voltage from its initial 56.7V.
What is their total AH as per nameplate?
