I pulled the trigger on this one after a lot of research. I'm designing the rest of the system to maximize the 12000XP's strengths. I can't wait to have my own real power plant... being grid-tied was cool, but I want more.
Maybe a stupid question, but if I have three equally sized 9 KW arrays, one facing southeast to catch the early morning sun, one facing south for the midday sun and one facing southwest for the late afternoon sun, can they all be efficiently connected to this unit ? It only has 2 MPPTs ?

What specific question do you have about your solar power setup?

It only has 2 MPPTs ? ChatGPT said: ChatGPT Not a stupid question at all! When using arrays facing different directions, you’re right to consider the impact of the MPPT (Maximum Power Point Tracking) inputs. MPPTs adjust voltage and current to maximize output, but they’re optimized for arrays with similar orientations and sunlight exposure. With only 2 MPPTs on your inverter, here’s how your 3 arrays would work with this setup: Group Similar Orientations Together: Since you have three orientations, you’d ideally group two arrays that have the most similar exposure patterns onto one MPPT. For example: Connect the southeast and south arrays to one MPPT. Connect the southwest array to the other MPPT. Potential Efficiency Impact: By combining two arrays with slightly different orientations (e.g., southeast and south), there might be minor efficiency losses due to the mismatch in sunlight exposure. However, if the orientations are not drastically different, the impact should be limited, especially if the voltages between arrays are similar. Alternative: If you want to maintain maximum efficiency with each array’s unique orientation, using an inverter with 3 MPPTs (or adding a small secondary inverter for the third array) would allow each direction to have its dedicated tracking. This would ensure optimal energy harvesting from each orientation.
Sounds like you might really want more MPPTs to maximize your PV array outputs. The 12000XP is particularly better suited for long strings of big panels pointed in no more than two positions, as the PV inputs are just paralleled into their respective MPPTs. Only two real inputs/MPPTs, but massive current capability.
It is not. If you have any questions or concerns about the warranty, please don't hesitate to reach out to the manufacturer at support@eg4electronics.com

The only product left to develop and add to their product line is a cost competitive heat pump water heater that absorbs the heat off their indoor inverters.
The inverter circuitry, switchgear heat sinks, and MPPT circuitry in this cheap inverter doesn't weigh 104 Lbs. No way! This Chinese manufacturer simply used heavy gauge steel in the construction of the inverter's box to fool consumers into thinking that they're getting more value (a heavier product) for their money. LOL!😂
Too bad it's storm season. The 12000XP high-frequency inverter is far more susceptible to damage from lightning strikes than low-frequency inverters. Don't take my word for it. Google " Are high-frequency inverters more susceptible to lightning strikes?"
The 12000XP still offers one of the poorest surge capacity ratios on the market and it can damage your appliances because it's designers went on the cheap and failed to use an output transformer to provide galvanic isolation. No thanks. Not in my home.
Too bad this cheap inverter doesn't use an output transformer to protect your appliances from potentially damaging exposure to DC current from its DC boost stage. No thanks.
I have the coolest video planned for this thing
looking forward to watchin git.
Can’t wait!
Oh nice 👍
In regards to a solar car port from your video, signature solar has some nice units
I’ve been checking your page for it!
Will this handle an EV charger?
Definitely feel like this will be the flagship. Even over the 18.
@@Dmkjr I agree. It seems to hit all the right notes.
Been waiting for you to drop this video Kelly. I think this inverter is going to be a big winner. Great video.
Thank you!

Ordered early this week and its like having ant in my pants. Huge upgrade from my 5k 110v inverter. Now I can really get ready for the next hurricane.
Congratulations on your purchase! Please don't hesitate let us know if you need any support!
I'm excited to test this out!
Very excited to add this to my lineup
This is a game changer

I also wonder about the 5 year warranty. Is it possible to purchase an extended warranty?
It is not. If you have any questions or concerns about the warranty, please don't hesitate to reach out to the manufacturer at support@eg4electronics.com
Can the 12000xp and the 6000xp be parallel together.
No, they cannot.
Hello Signature Solar,
Here in Peru we have 220V. 60hz.
Can I use the full 12kw with 220 voltage on this inverter?
Thanks,
Peter
Estoy seguro que si. EG4 tiene muy buenos sistemas.
It is a split phase 110/220v inverter
Does the transfer switch automatically switch from battery to grid when the battery pack is empty?
It does it out of the box but it will switch to bypass AC power once the batteries reach the set V/SOC

@SignatureSolar so.. china? Any chance for a Taiwanese or American made version at a higher price point?
can it work with my 2 6000XPs ?
You cannot parallel the 6000XP and the 12000XP
🔥🔥🔥
Is this a LUX unit?
Kelly, Kelly, Kelly, Kelly, Kelly, Kelly, Kelly, solar power yay!!

Yes, no problem!

would have liked to see the inside of the box. maybe down the road?
Can you use the 12000xp with a 6000xp. I have a 6000xp but need more power. Should I just get another 6000
Either would work, but 3x 6xp would give great redundancy!
@@SignatureSolar just to clarify here, the 12000 will communicate with the 6000 xp?
I’d love to see a toroidal transformer based all-in-one low-frequency inverter.
This seems like a way better inverter than the 12KPV and 18KPV.... My 12k has been great
I was really excited until I heard "5 year warranty". That doesn't say much about the build quality to me.
Only a 5 year warranty???
