Re: Battery Test Procedures, RE800

They went into service March 29, 2017. To your comment below on 4000 watts, even my coffee pot @ 1500w will cause the voltage to drop enough to run the gen. Not good, at 2 years, with a supposedly high capacity type battery bank. Even an ordinary, good conditioned 4-12V VRLA batteries can handle 15...

Re: Battery Test Procedures, RE800

670 Ah. Keep in mind the sun was up and PV's active.In the past I have not had any problem drawing such a load. I have 220 power tools that at start up hit 5000 watts and then run at 3000. and no troubles. Oh ok. I re-read the post, it was after sunrise. So how long have you been using the battery ...

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?

Re: Load Measurement Accuracy under 1Kw inconsistent

And probably on that .1kW reading that you see in MATE3, the load current is shown as 0A :-) That is for another discussion.

Re: Load Measurement Accuracy under 1Kw inconsistent

Thanks. Just to let you know, in my own testing, inductive loads produced lesser load values in MATE3 compared to a real kW/kWh meter.
I got better results (MATE3 kw and kWh) readings when I was testing an Outback system with purely resistive loads, power factor of 1.

Re: Strange efficiency readings

@cflocker, one thing I noticed, your idle no load battery consumption is too high. If you look at hours where there is single light blue bar (from battery), the consumption is .2 kWh, that is 200 watts in a span of one hour. The idle, no-load power consumption as per website is only 34 watts. So, th...

Re: Radian and AC coupling in non Grid Tie mode

As in the previous comment, I think Outback is quietly staying away from AC coupling, as evidenced by non-availability of parts like ROCB. Anyways, who needs an AC coupled system when OB inverters like the Radians and FXRs are already fully interactive? Being battery based inverters, as contrast to ...

Re: AGS behavior

Here's a dissenting reply :-). The Warm-up and cool down settings are only accomplished via a programmed start, example Must Run. If you manually start the Gen via MATE3, the Gen AC input will try to synch with Inverter output and mode will go to to USE, meaning the relay inside the inverter closed ...

GS8048 or GS8048A has two modules (inverters) inside are capable of operating by just one module. By itself (one module) it has already a split phase output of 120/240 and can run independently from the other module. Also, the way this system works, if it is configured for the module control in auto...

Re: Controlling the CC Aux Port

I have verified that the Optics and MATE3 display always align/agree, and provided that the CC display is on AUX screen, the CC will align too. I have measured the OFF and ON voltage as 0VDC while OFF, and ON is 13.5VDC.

Different experience here. It actually works from Optics, provided you put the FM60 or FM80's display screen to AUX screen before making changes from OpticsRE. Steps to reproduce: 1. Locally put the CC's screen to AUX screen. 2. From OpticsRE, go to device map for FM60/Aux Control, then cycle the co...

Re: AC input from outlet tripping GFCI

How long did you put in the 120VAC input from the normal outlet?
The way I understand it, your system is wired for split phase 120/240. And convention follows that If you have to put an AC input (whether from outlet/grid or generator), it has to be another split phase 120/240.

Re: FX Aux mode already occupied

Because AGS functions are mapped exclusively to the aux relay of an inverter. CC has its own mapped functions for its auxiliary output like Low battery disconnect, night light, etc.
