I got away from battery communications between my Growatt 12k and my 4 Lifepower4 batteries since the Growatt was raising an 04 error and shutting down whenever my 4-ton HVAC turned on. My EasyStart 368 app shows 63A inrush @240VAC, which is about 15kW for one second. This translates to about...

Sometimes their website has the shipping wrong. You should contact them by phone to verify.

I would imagine that the Sol-Ark is ignoring the GEN input since it sees power from the grid. Have you measured the voltage at the Gen input to the inverter? If there's voltage present, there might be an inverter setting you need to change to set gen priority over grid.

You would think there would be a market for a portable generator booster which could plug into any generator output and serve as a passthrough unit until such time as a short term boost is needed. Then, an included battery/inverter combo could provide the boost and then return to...

Looks like there is room for this bracket to be changed to a "C-channel style" for added strength in the next production run. Or just use thicker gauge steel.

It's a 4-ton unit, with a EasyStart 368 soft starter installed. Peak inrush is down to 55A from 129A.

These are HF inverters. Is there a published surge rating? I would need 2 units for split phase 240V output, so if I buy 2 inverters and match them with 3 or 4 Lifepower4 rack mount batteries, can they start a large HVAC condensing unit...say 55A inrush at 240VAC?

With these high tech, multi-function inverters and rack mount batteries all connected and communicating, shouldn't stuff just work? You'd think in this day and age, with a laptop or smartphone that you could just run through a simple setup wizard where you select the battery model, split phase...

Yes. This is all driven by the WEF. I've been down the rabbit hole and it is deep. Literally hundreds of hours reading factual testimony and evidence of fraud. The best analogy for those of us who are awake see the production for what it is...think of The Truman Show, where we are the audience...

With regards to power in a prolonged grid down scenario, some people are saying that many secondary utilities will no longer be available. My primary emergency backup power is batteries and an inverter, but I also have a tri-fuel generator for recharging. I have natural gas to the property and...

If it doesn't work, you can always get a Chargeverter to put between the generator and batteries. This is what I use, otherwise the house would attempt to run on the generator since the inverter would want to pass through that power to the loads. My generator isn't large enough to run the larger...

I have an older 4-ton HVAC and even with an EasyStart 368 soft starter, the inrush current can be as high as 63A @240VAC. My Growatt 12k inverter can start it, but it is a low frequency model and has a large transformer. If you have other stuff running when your AC turns on, you might be limited...

No, the one I'm talking about is in a different league:

Don't forget you can parallel two inverter generators if you think you will need a lot of continuous power for longer periods but don't want to run the machines at a high % load. You can get clean, quiet power but it is going to cost you: This guy has two Honda EU7000is paralleled in an...

For anyone new to this...the battery to battery connections are using VDC where the voltage is lower (typically 48V), so the corresponding current at any particular power level is higher, requiring thicker wire. Wiring to the Smart Home Panel is VAC (typically 120V for each leg) where the...

You suffer from projection. You create scenarios, make assumptions and then deliver your verdict. You must not actually be on Twitter since you believe experts cannot make their wisdom available there. You should know that actual experts reside there and they not only post their thoughts, but...

Will just did a video on the 1200W 12V version: It is a LF inverter with a large transformer. Short term peak output is listed as 2200W. https://m.media-amazon.com/images/I/81+JTuz21sL.pdf

I would take the credit for any new purchases and/or additions to a system and if the IRS doesn't like it, they can tell me where I went wrong.

What you can try is disconnect one of the batteries and connect it to the Chargeverter. Then power the Chargeverter from your LV6548 (running on the other battery) and see if it charges the disconnected battery as expected. If it works, then maybe your Honda is putting out questionable power or...

That's what I did...replaced the original cap and contactor at the same time. Here is an excellent video of a technical discussion with the designer of the Easy Start...they go into great detail about the benefits to your system:

Based on the OP's post history, he has had various previous issues related to neutral ground bonding, use of auto-transformer, and various BMS problems. While it is possible that 4 inverters simply failed, it is also possible there is something not quite right with the setup...or the...

Two Sol-Ark 15k units would be my choice if I could afford them.

My system is for emergency backup only. I went with a 20kWh rack mount battery system and a 12kW all-in-one split-phase low frequency inverter. I don't have solar. For recharging, I have a Honda inverter generator (converted to tri-fuel) and a Chargeverter to convert that power directly to DC so...

Embarrassing: Glad I have the original/yellow rack setup.

Once a person (especially an engineer) has put so much time and effort into a plan, they tend to be determined to carry on with it despite the clamor from others. It is a natural human characteristic we all struggle with. Been there.

Watch the movie "The Road" (2009). A memorable experience to say the least. They kept their "food" alive in the basement until it was time for processing... Also, in your scenario I highly recommend blackout shades and/or black plastic contractor bags taped on the inside of the windows.

As for the wife and the views from the house, you can plant some 6 FT Leyland Cypress trees to grow into a privacy wall over the next 5 years. Plant a line of them just before the first ground mount array from the house. The Leyland I planted about 5 years ago is already 25 ft tall and about 10...

I do the same thing with my system. I have a 12k inverter with 20kwh of rack mount batteries for emergency backup only. I connect to my interlock via a generator cord and input box. The system is off and disconnected unless there's a power outage and I hook it up just like a generator. If an...

Not too familiar with those batteries, but I think you need to raise your charge voltage a bit.

Hmmm...first post attachment indicates L1, L2, N on the diagram.
