Is it 120a charge and 8kw input capacity?

Your solar input is limited by the inverter AC load and charging limits. Any excess solar would be clipped.

Unfortunately the lower temperatures and sun angle are preventing me from retesting this.

This time of year, my solar array tops out at 6,000 watts and my strings are exceeding the 480v mppt limit.

Makes sense. That’s where my 120a question came from as I thought you were hardware limited to 6000w dc in but it’s the season.
 
I feel like I'm in the right place for asking this question. I'm going to put the 6000XP in my 50A RV.

When I'm connected to 50A shore power (120/240), everything should work as planned when connecting my L1, L2, N, and G to the XP.
However, if I pull up to a 15-30A site and use a dog-bone that takes 120V singe phase and spreads that phase between L1 and L2 (Not split phased), would that cause an issue?


The manual says it can take grid input between 120-240 volts so I messaged signature solar to inquire. Below is my question and their response...

ME: Is it theoretically safe to connect inverter to 120v Single Phase shore power (15-30amp) that is spread evenly between L1 and L2 via a Dog bone adapter. (see below)
  1. Of course I would disable the Ground/Neutral bond on the inverter
Signature Solar: It's not safe, we advise running it through the breaker panel, treating it like its another load. That Plug would not work for this application.
Why would this cause an issue? I need to be educated.

Thanks!
BONUS... While I'm here I might as well share the other questions I asked since I'm crossing my fingers that the answer they gave me is False. Some of the above comments in this thread support the answer that I want to hear.


ME: When the inverter is connected to shore power via a 120/240 50Amp outlet. Does the Inverter “pass thru” the full 12,000Watts if needed? (50 amps at 120V on each Leg). If so, does the output limit of 6000Watts only refers to how much total power the inverter can supply when inverting from DC to AC?

Signature Solar: Its actually 25 amps per leg for a total of 50a for both legs. 25x120=3000x2=6000w for pass through, I don't know why its phrased "Rated Output current @ 240v....25a" but i checked with two colleagues including my team lead and they confirmed its 6000w total at 3000w each leg. From DC it has a maximum of 8000w with 4000w per MPPT. Whereas AC to AC is 6000w.

Can anyone confirm the accuracy of this answer?

The answer to the first question is I’m sure correct, but the answer re: pass through power is definitely mistaken. The pass through power is twice what the inverter supports. It will pass through 50 amps on each leg. Mine passes through ~30 amps per leg on a regular basis when I run my dryer combined with other loads at the same time.

Pass through is rates at 50 amps per leg. Psst the breakers are actually rated for 63 amps. (I have no idea what the relay is rated for) side note 63 x 80% = 50

No the inverter will not allow an AC grid connection on a single 120v leg...I don't recommend bridging L1 with L2.

Great news regarding the pass thru. I've had 4 separate people at Signature Solar tell me the grid pass thru limit is limited to 3000W on each leg. Sounds like you and @AZ Solar Junkie above have both tested it first hand. Thank you!!!!

Yeah I don’t know what someone was smoking. It’s clear even in the specs in the manual…

EG4 6000XP Neutral-Ground Bonding

Let's start with a snip from the EG4 6000XP manual. What I'm getting at here, is a lot of people, including @Will Prowse in his latest video (8:03) are mistaken on how the 6000XP handles neutral and ground bonds. The inverter does NOT dynamically bond. This means that if you plan to put an...

I don’t recommend this inverter in an RV whatsoever. Furthermore it cannot accept just 120v input - it must be split phase 120/240
 
I haven't seen anything posted on the AC grid feed to the inverter and the manual isn't clear. What size breaker is needed in the main panel: 40a or 50a?

Thanks, @ChrisG and @AZ Solar Junkie. That's what I thought. Going to replace a 6000ex with the 6000xp, currently using a 40a breaker. Looks like another part of the upgrade.

I just installed mine. Bought two 50a breakers one for main panel and one for critical loads. Think I got them both for $32.

50a and 8awg thhn wire.
Click to expand...
Utilizing 8 AWG copper and 6 AWG aluminum conductors is generally not recommended, even though they fall within the 50 AMP to 60 AMP capacity range. This is because, as per the National Electrical Code (NEC), the maximum operational load of an electrical circuit shouldn’t surpass 80% of its capacity. 6 AWG copper is the recommended wire size for a 50 amp circuit.

Hmm. Doesn’t say that in the manual, I’m using 10ft of 8awg copper thhn for each run. I’ll never have 12k passthrough anyway, don’t have the loads to support it in sub panel. Would have gotten a larger inverter if that was the case. Guess to be compliant I could downgrade the breakers to 40a.

Yeah if your loads aren’t going to be demanding the 50 amps of bypass you should be fine eh. Downgrading the breakers is a good idea though to protect the 8 gauge wire… every situation is unique.
 
Out of curiosity, looking at the specification, it appears the 6000XP has an AC input limit of 37.5amps (9000W). So I can account for the 25amps (6000W) going to the loads with the remaining 12.5amps (3000W) charging the battery. So how does one make use of the remaining 12.5amps (3000W) of the 50 amp by-pass specification?

Is this a buffer for intended overload operation?

When it’s in bypass mode, it can pull up to 50 amps and pass them directly to the loads, minus any power being used for charging the batteries. If you’re not charging batteries either because they are full or AC charging is disabled, the full 50 amps could go to the loads.

@AZSolarJunkie, Thanks for your assessment of the 50amp bypass, I follow and agree.

However, my curiosity is more focused on how a home system could be designed to make use of the full 50amp by-pass. While being limited to the 37.5amp AC IN specification. I feel I'm still mis-understanding something.
