eah, I've had troubles with this bank. I would've gone with SimpliPhi but can't because I am the dreaded self installer. That voids the warranty 'cause I don't have a license.
I missed your latest discussion with raysun and sodamo in the other thread.

Yep, that Controller <-> Battery disconnect needs to be added.
Also increase the wire size to preferably #2 AWG. Breaker should be a 125A 300V which is the standard Outback FM100 GSLC configuration as I noted earlier along with the application note.

Re: backup generator died, portable generator install

With the Champion, limited to about 7kW continuous output, I would use the settings you have shown for the master inverter and set the slave to 0A for charging and AC input. For the long run: Is that Kohler 14 RESA recommended over a Generac Ecogen? I have a Kohler 14 RESA that is lightly used (I am...

Re: help with 1-line diagram

With the built in GFI or AFCI, the breaker on the output must be rated for 300VDC and the standard size is 125A.  fcwlp - Good to see we are in agreement on most, but why is 300V rating needed when voltage level there is only around 48 volts? My understanding is that if a fault occurs there is a po...

Re: help with 1-line diagram

You are correct, there is no GSLC. On the transfer switch, the breakers will trip if there is an overload but there is no automatic transfer function. Starting at your PV array: The combiner box currently has 3 30A breakers. Per CSUN 390 datasheet the maximum size should be 20A and based on the Isc ...

Re: Recommends for "putting system to bed" for the summer

Hi Jim, I know you have had challenges with your FLA batteries and trust your new SimpliPhi's will reduce your battery challenges. My advice was based on him needing to water his batteries every couple of weeks which suggests to me that either the absorb voltage is too high or the absorb time too lo...

Re: help with 1-line diagram

Does your system have a GSLC (GS Load Center) below the Radian? As you have a FNDC, my guess is that you do have a GSLC. Within the GSLC there is breaker for the PV + input to the CC and a breaker for the Batt+ coming from the CC. The FM100 is a 300V capable CC, so the breakers must be rated for 300...

Re: SOC keeps dropping

Also, I never see the FM100 with a solid green second LED, which would indicate "float". Day or night. At night it's solid amber, as I explained above. During the day it's flashing green indicating "GT Mode". Not sure what that is telling me. On the FM100 a solid amber just means you are => 1.91V/c...

Re: SOC keeps dropping

The absorb timer for the FM100 is set to 1.0. I'm guessing that's hours? On the inverter charger, both absorb and float times are set to 1.0. As per your earlier detailed instructions, I checked the inverter charger AC limit and it is indeed 15A. Any additional tips based on my answers to your ques...

Re: backup generator died, portable generator install

There are two parameters to set: Generator Input AC Limit. This should be set to the maximum continuous rated output. I believe that is 62.5AAC for the Ecogen 15kW. Inverter Charger Input AC Limit. Set maximum below the Generator Input AC Limit. If 24AAC is maximum, set the parameter to that. The M...

Re: SOC keeps dropping

The sell voltage is 52.8V (Not sure why as Lifeline recommends 52.8V. Is that a problem?) And what should I drop that rebulk voltage to? Thanks. My Lifeline manual does not give a sell voltage. The 52.4 sell voltage I recommended in the previous post was based on running 0.8V below the desired floa...

Re: Recommends for "putting system to bed" for the summer

Slight correction to otherwise good advice: High water consumption would be associated with end amps being too low, as that would prolong the absorb cycle. If it's high, absorb will end before it should and use less water. FWIW - Mike Mike thanks for the correction. I had had my evening bourbon whe...

Re: backup generator died, portable generator install

Pardon me for stepping in and being the contrarian. The generator needs to be able to handle house loads and charging simultaneously, otherwise it will see a pattern of DROP and USE events from the inverters. This is always a hard condition for generator and transfer switches to handle. It may have...

Re: Recommends for "putting system to bed" for the summer

Interesting question. My recommendation is to make no changes to the settings and to not to put an additional load on the system. Your friend will probably learn that there is no water consumption as there will be few full charging cycles. If you have been putting water in every few weeks while you ...

Re: backup generator died, portable generator install

The Champion generator can be used in place of the Generac. I am not sure if the Champion can use the AGS function but since you use it so seldom you can easily run it as a manual system. Make sure to disconnect the N to G bond that is likely present in the Champion. In manual mode with Mate3: 1) St...

Re: SOC keeps dropping

Raysun did a very good job of explaining why we normally set the CC and inverter V set points 0.4V apart. absorb = 57.2V float = 53.6V refloat = 50.0V rebulk = 52.8V The sell voltage is 52.8V While they set the float 0.4V higher than Lifeline recommended, I do not have a major issue with it.

I guess this means I'll still need a N-G bond in the Skybox.
Check the generator first. If you have not modified it, the N&G are likely already bonded there.

The readings on the Mate3 itself are correct. I am running the latest firmware on my Mate3 and I got the same result that you did. Someone else will need to confirm if it shows up on their Mate3s. If your Mate3s is on your network, just type the Mate3s' IP address in your browser. IP address shows u...

Re: Why does is my End Amps reading on the IP address ten times higher than it shows on my Mate 3?

Hi Cisco Ken, your not the only one. I had never logged in to my Mate3 directly in the past, only going through OpticsRE. You are correct that the End Amps shown are 10x. I also see some other A values at 4x which is probably related to a firmware change last year. The image below is from the "Setup...

The inverter mode is GRID TIE
Have you confirmed on the Mate3s that there are no FLEXtime changes to Mode?
Are you selling back to grid? Based on your location I assume you are with APS. What rate plan are you on?
What are your float and sell voltages set at?
