Right now I'm at C. Solar then grid then whole house gen. Guess I need to step up my game. Oh wait. I have a Miller Bobcat 250 that outputs 50a so that's plan D! But man, that thing loves the gas. We used it to run the house for 12 days after hurricane Ike and it was about a gallon an hour.

Hybrid D + A.
Miller generator recharges batteries, then shuts off.

It's actually C + A. The plan is run the NG genny and charge the batteries since it's already connected and is cheaper to run. But yeah, backup plans for backup plans is the way to go.

We are in the middle of a barndominium build. Efficiency considerations in mind when building. Slab foundation, wood stove in middle of house, fans in every room, mini split head in 3 bedrooms and great room (6k, 6k, 9k, 15k) n/s build with 12ft overhang on south wall, N/S breezeway thru center of house. In the worst of days the mini splits will only be used maybe 4-6hrs. Most of the year it’s comfortable without them, could probably make due if I had to conserve
Propane (500gal) a dedicated generator and I have 2-5500w champion dual fuel inverter generators as well, gas range for tertiary heat. Gas dryer
Spray foam insulation, light tan roof. 500ft well, 2500gal above ground storage, float pump, pressure tank, and 14 IBC totes plumbed for roof rainwater runoff.

Goal was solar and battery for A, propane B, wood natural breezeway and lighting C, Stone Age with steel walls and pockets of brass for plan D

Power pole is 3 miles away so I need plan A and B to go dead nuts. Plan C for good weather and easy meals, no big deal or
Plan C for the times I screw up and forget to have the propane filled, can’t get the propane filled, can’t start any of 3 generators, the relabeled wish . Com inverters broke and system is down, and it’s either a fluke heat or cold wave.
Although the wood stove will be often used in most situations because we like them and cut a few cords per year.
Plan D is reserved for any plethora of fanatical post apocalyptic situation that I manage to escape ?

Maybe I should just suck it up and take the luxpower unit more seriously in my considerations.
At least that somewhat bridges the gap between the 2-3000 dollar range and the 10k + range of dual schneider/Outback/midnite units.
Idk if it’s functionally more reliable than the GW or not, but it’s bound to have 10x the user base so I imagine issues are more likely to be resolved.

Take a close look at the spec sheet.

Note power ratings such as UPS. 12Kw off battery. Next is peak power with PV, we see the 5 minute and 10 min ratings and a 13.5Kw rating without PV.

I would say it is actually 12Kw or less off battery continuous. I haven't seen anyone test these on video as battery only power, always seems with PV input and even grid hooked up. I mentioned the continuous rating on battery only to James and he ignored it. Which tells me I might be correct in my suspicion about the actual rating. SolArk gives a continuous rating off battery of 12Kw. Don't you think this might be important once the sun goes down?

Don't you have one of these @Quattrohead ?

24/7/365 rating, is the only one that matters to me.

I agree on all aspects. Which seems similar to the Growatt on battery, 2-schneider on battery, 2-6048 on battery etc. (within 1-3kw) so about 50a ac available on battery only? Seems reasonable and kinda what I was felt I was facing regardless of decision as dual 15k or quad schneider is simply not in the cards. I have no grid so pass thru doesn’t seem relevant as my generator is not larger than the inverter (hoping I’m understanding how it all works together)

I agree and the 5 minute and 10 minute ratings are marketing. Gavin ran a loads test and it failed the loads test because it shut down in less than 5 minutes. I mentioned it in this post here.

It was glossed over having not failed because the unit did put out close to rated power but certainly not the length of time. Adam noticed it. Latest comments from those closely connected to Lux is there are some firmware updates to give max output under battery power. My thoughts are to accomplish this is to raise the shutdown temp thru firmware. This can't be good for the unit long term.

This could be a good unit as long as it isn't pushed hard. If it gets pushed on hard long term, it most likely will not last long. If one needs to load it down daily, then 2 units would be a better choice. This increases cost considerably.

Yes I do but I have not pushed the power output yet, I was more into voltage stability and backfeed issues.
However, I have now reconfigured it and moved all loads to it, even my power ho dryer. I was going to keep just the dryer on the SP6548 pair but that is a lot of standby power for occasional use load, so I'm gonna see how the EG4 18k handles the full house load. Shit or bust ?

It actually runs hotter with less loads on it because the fans don't even startup til around 6kw of PV input or/and 6kw of output. Then the internal temps drop by a considerable amount. The unit runs scary hot in my stupid hot garage, has been uncomfortable to keep my hand on it sometimes.
Example - this morning it was charging the batteries from grid at 3.5kw for 2.5 hours before the fans kicked on, temp went from 140F to 104F in 9 mins. Garage temp was around 88F during this time.
All of my equipment will be in conditioned space in the home I am building.

The lvx6048 has an input rated for 450vdc, range of 120-430, 27a input current, 100a to battery. The new UL-WP version has a 600vdc dual input 15a per, 60ax2

These two units are completely different models (not related in any way). I have no idea why MPP Solar kept the same naming convention for both, as it confused the heck out of the market.

Just saw this post. https://diysolarforum.com/threads/wire-trough-wireway-for-multiple-18kpv-inverters.63648/post-826318 It is as I expected, these units seem to miss the mark on just battery power.
