State of Confusion
Hello everyone hope all is well - first time poster here.
This seams like a good place to learn so I submit to you a project I started.
First - My SolarEdge system inverter is not capable of accepting battery back-up and has 5 more years of warranty. When the grid goes down I'm SoL

So I created a little monster and I don't want to smoke it, the cost is to high.
It's not complete yet but close enough to get me worried. The thought around the design is not all my idea.
Guess it goes without saying I plan to double up a 24v system hopefully for longer runtime.
Yes the input AC cable snakes through the box but holds it steady. (no rubber band or chewing gum on that one but almost)
Yes the duel fuse is mostly redundant .... mostly.
I have tried to draw on all my experience both good and bad to put this together but sometimes I can't trust myself ... lol.

Mainly this unit is a temporarily supply power for some small personal devices, intermittent medical equipment use, 2 small refrigerators, 1 deep freezer and small swamp cooler. I have a duel fuel Champion generator on propane and (4) 200w panels to charge batteries if necessary but intend to keep the unit plugged in most of the time. I am very worried about power failure and when it comes to my family I'll do all I can to prevent an issue.

So .. feel free to dig in and let me have it if necessary I can use all the help/ideas/criticism that I can get before it all goes poof "UP in Smoke"
I'm not even sure about the start up sequence on the LV2424. (I will be reading the forum posts)
I was wondering about the neutral/grounding thing but found a nice explanation that I'll post here.

FYI - My new SOK batteries are talking all the time on Bluetooth, not sure if I like that or if it can be turned off ......

@UpInSmoke, your project design is very much what I imagine our build would look like. It’s off-grid back-up power - check, it’s wheeled/portable - check, it’s an “All-in-One” design - check, it has an AC output circuit breaker-protected distribution box - check, it has some hefty battery storage - check. In summary, it’s what I’m looking for. Very nice!

How many weeks or months have you been engaged with this project, from design concept to now, and if you don’t mind, how much in cost is wrapped up in it thus far?

Thanks for your reply to my ‘newbie’ post. It was my account’s first! :)

Sweet man I'm also building a similar mobile system, but instead of a steel trolley (to lessen the weight) I opted for a printer stand with reinforced wheels.

I'll be using a PDU power strip combo (circuit breaker / surge protector + watt meter) normally used in computer datacenters which I think is quite compact in size.

So where are the solar panels? You need to do a Real world energy audit to see how many Watts you intend to power and your battery capacity.

Hello @crystalForm
I started with the main system then fell overboard ... lol.
Once all the parts were here, build time was about a weekend. Got the main portable idea from hand cart versions I have seen online, then about a month to figure out how big a can of worms I could open.
Putting together a solar trailer to mount the (4) 800w panels on, got a ways to go on that one.
No cost on that yet but seen a little trailer set up on line made to accept (your) panels for around 2900.00.

Approximate cost ... so far
3500.00 / LV2424 Main off grid inverter system with (2) 206AH LiPo's and (4) solar panels.
2000.00 / (2) Extra 206AH LiPo batteries
240.00 / HD 2000lb Hand Cart (batteries are 49lbs each)
200.00 / 70 Amp Midwest panel
200.00 / CE 6532UG 30 Amp power distribution w/GFI
35.00 / Adapter Cord TT-30 Male to L14-30R
90.00 / Ridged 50ft 10G 10/3 In/Outdoor cord (when charging from the grid)
________________________________
7000.00 w/tax give or take

Not included or shown is my Champion Duel Fuel 3800w Inverter generator on propane for Back-up charging the batteries on cloudy days.
(propane is so clean burning - no gas smell)

I probably could have done without some things but ..... naaaa ... it wouldn't be me.
and still not done, remember the solar trailer project ...

If my wife sees this post, she may not fish my corpse out of the water ... I'm dead meat ... lol

"mount the (4) 800w panels"
Correction panels are 200w each x4 for a total of 800w ... sorry

Yes I do. moving slow ... old .... building bracket to hold panels on trailer ... lol
Deep Freezer ran around 14w average and the swamp cooler average was around 550w. First run went about 24 hours before getting down to 23v. Started with a charge of 25.4 with no pre cycling batteries and no charging from the grid during the test.
I'll be more precise next time. My full charge is set to 27.0 @20A from the grid.
