EG4 6000XP vs. 12000XP: In-Depth Solar Inverter Comparison - Find the Best Off-Grid Solution!

[@prepsolar787]

its been a year now with my eg4 6000xp working 24/7 and not a single hiccup

[@MyWasteOfTime]

The biggest thing for me is that the 12000XP allows 35A per solar input. 17A on the 6000XP just wasn't enough for my setup.

[@SolarHomesteadLife]

Good point! The 12000XP’s 35A per solar input can be a game-changer for setups that need that extra capacity. Thanks for sharing your insight!

[@HybridShedIraq]

The issue is with the old panels 400w/300w panels with new panels 580w you can add 7-8 panels in series for each mppt without the need of combiner or parallel. i have the 6000xp eu variant disassembled.

[@MyWasteOfTime]

@@HybridShedIraq Yea I'm running 330W panels since I got them for $0.24/W 2 years ago!

[@HybridShedIraq]

@MyWasteOfTime new 600w panels here now are 85$ a piece

[@MyWasteOfTime]

@@HybridShedIraq Yep Everything has went down besides those damn batteries!

[@wdwtx2.0]

While the 12000XP puts out twice the AC power, it allows THREE TIMES the PV input. Also, while the 12000XP puts out 12,000 watts AC, it can put out 12,000 watts DC to the batteries. AT THE SAME TIME! 24,000 USEABLE watts. That is HUGE. I really wish they would use these features in a hybrid unit.

[@SolarHomesteadLife]

@wdwtx2.0 You’re spot on! The 12000XP is indeed designed to function as a hybrid unit, allowing it to handle triple the PV input and provide that simultaneous 12,000 watts AC output along with 12,000 watts DC to the batteries. It’s incredible how much usable power it offers for larger setups at a very affordable price. This functionality really sets it apart, especially for high-demand off-grid systems. Thanks for highlighting it!

[@fredriebe2487]

Do I need at least 2 EG4 Powerwall batteries to operate the 12000XP Inverter, or can I start with just one of the EG4 Powerwall’s & scale up at my convenience & budget?

[@SolarHomesteadLife]

Hi Fred, great question! For the EG4 12000XP inverter, it’s recommended to have at least 400 amp-hours of battery capacity to ensure stable and efficient operation, which generally means starting with two EG4 Powerwalls. My understanding is that each Powerwall is 48V, 280Ah, and 14.3 kWh (LiFePO4), which is almost the equivalent of three 100Ah server rack batteries at 48V. This setup will provide enough power to handle larger loads and help protect the longevity of both the inverter and batteries. Starting with a single Powerwall might work for light usage, but it's best to meet the 400 Ah recommendation if possible. I’ll also reach out to Signature Solar on Monday to confirm and will update you if there’s any additional information. Hope that helps!

[@ericmatthews7264]

According to EG4 they say 2 power wall minimum

[@hacked2123]

Not sure why but at 8:19 you said 4x 6000xp's in parallel as if it was some sort of limit. Both the 6000xp and 12000xp are able to provide 96kw of power if the system is configured properly

[@SolarHomesteadLife]

@hacked2123 Great catch! You’re absolutely right-the EG4 6000XP can support up to 16 units in parallel, which allows for a total output of 96kW if configured properly. I mentioned 4 units as an example setup, but there’s definitely a lot of flexibility to scale up for higher power demands. Thanks for pointing it out!

[@P81OS2]

Great job on this one, sir!

[@SolarHomesteadLife]

Thanks! Really glad you enjoyed this one. I always greatly appreciate the support!

[@AyushmaanGanotra]

Hey so I live in a fairly large 4 bedroom home. Normal appliances such as laundry, fridge, etc. I'm leaning towards 6000XP, but would you have any recommendations? Don't think we'd peak over 6000 most of the time.

[@SolarHomesteadLife]

Hey @AyushmaanGanotra! The 6000XP is a great option, especially if you’re usually staying below 6000W. To make sure it’ll cover your needs, I’d recommend doing a quick energy study on your appliances, including things like air conditioners, water heaters, and any other high-draw items. This way, you’ll get a clearer picture of your actual energy usage and any peak demands. If your needs are close to that 6000W threshold regularly, it might be worth considering the 12000XP for extra capacity.

[@MrBobSanchez]

Thanks for the comparison! You got my subscription!

[@MrBobSanchez]

Besides the smart load port, do you think there’s any justification for a 12000XP over 2x 6000XPs?

[@SolarHomesteadLife]

Awesome, thank you for the sub! I'm really glad you enjoyed the comparison!

[@johnfitbyfaithnet]

How ​@MrBobSanchez how about wire and connector costs to join the 2?

[@MrBobSanchez]

@@johnfitbyfaithnet Fair point. I already have 2x 6000XPs, just wondering if it's worth making the switch as I could use more solar input.

[@WattsMiner]

Using a chargeverter, or even a few on a load panel, is the best way. It turns the generator into another dc supply and makes everything run better.

[@SolarHomesteadLife]

@WattsMiner Thanks for sharing! Just curious-when you mention a load panel, are you thinking of a DC load panel specifically for appliances that run directly off DC? I know some folks use DC panels to bypass the inverter for things like LED lighting, DC-powered fans, and even battery charging systems. Definitely an interesting setup approach! Let me know if I’m on the right track here.
