Posting my first pictures of a couple of Stacked Rosies. (no solar yet, just whole house battery) I nervously turn off the AC Input to run the puppies on Battery. I saw a slight dip in lights, but everything kept running WooHoo!. But, I still cannot figure out how to get the second Rosie...

After a couple of different calls and emails to Midnite Rosie support, I'm HAPPY to state that my stacked Rosies are talking! I need to do some further testing, but we discovered 2 possible issues. a. It's Midnite recommends that the stacked Rosies AC are wired together in a specific...

So I’m added a Class T fuse to my battery. Made sure the master switch was off of my monster 600V power switch. And as I was tightening the bolts, my knuckle touched the negative wire and I got a minor zap. 😳😳. So I stopped what I was doing, brought out my volt meter and sure enough...

Here you go. This is Rosie running 12kW at 255A battery draw. There is no inverter noise, just fan noise. And the case being open is making it louder. https://1drv.ms/v/s!AhJrl5-Da3WVjKRZ1nUcj7xDPUqSYw?e=5puizc

There is no sound at 2kW load. Maybe a slight buzz and no fans running. Here is me running 4kW into the batteries with zero noise.

Look at EG4's chargeverter. This doesn't connect directly to the inverter, but can be connected to the battery and you can control voltage and current for the charging. I'm using this for the same purpose as OP wants. (extended outage without grid as the backup).

Yes, it only has power when the air conditioner is running. I have it on my 5 ton and that’s exactly how it functions and I think there is a YouTube video that also states that.

I'm not sure this is a "real" stress test because I didn't break it, but wanted to share my results from my stress teset today. I was impressed with Rosie. Load: 13859W on AC, 12370 on Battery (something finished or turned off) Things providing the load. 2 4gal bosch water heaters (1440W...

Yes, looks like same company(or at least similiar model #), but in vertical configuration. It said it has a JBD BMS cut-out. (Pretty funny that this was just posted a couple of days ago). Totally different power connector, BMS and power cut-off switch on the vertical model. (IE, it...

Does anyone have a favorite vendor in the greater Austin area for a raceway and related components?

Their epanel for stacked Rosie’s is still not released. (Was supposed to be Feb). Hence the DIY. But. The diagram for the stacked ePanels are still showing separate neutrals out to load panel.

Just received the 2 boxes today. I was pretty impressed with the shipping time. (1/20 - 2/13) Now the fun starts. (the 4/0 cables that I ordered for this build are massive).

Basically that is a "off-grid" scenario or a hybrid scenario that includes batteries and/or generator. There is an offgrid forum on this site that might be helpful for you..

Well I buy BlueSea breakers and Mega Fuses, so not cutting corners on safety. Except maybe this time???? <sigh>. And I “was” buying a BlueSea Class T, so not intentionally cutting corners on quality stuff. When buying fuses I always buy extra because they are once and done. So I was...

You would be surprised. Battery prices have dropped significantly. Just saw a 15 kWh from AliExpress for $2600. To be fully covered, I think you need a battery. What if it’s night and the grid goes down?

MNGP2’s are required to configure Rosie’s, but you only need 1. So if you buy a Rosie and a Barcelona, then only 1 MGNP2 is required, they plug together with CAT5 and they all know about each other. Interesting note. You do not need an MNGP2 to run a Rosie. Once configured you can...

I’m doing something similar. I have 1 main panel and 3 sub panels. In Texas, new homes have 240 breakers outside, so all our big loads including the 3 sub panels are all served from the main. So I’m creating a new critical load panel just for the backup and moving just some key things to...

Yep, wasn’t happy about that, so it clearly stays out of the critical load! LoL. (We debated gas versus electric heater when we bought the house. Regretting the electric choice!

The JKBMS 150a surges for 300a for 2 min.

Answered my own question. The Neutrals are common inside the Rosies, so by following that logic, the bypass would also use the same common neutral.

My research from internet folks was 50/50 for and against and EVE said it was ok to mount this way, so rolling the dice.

After installing the wheels it was unbelievably obvious that this was very unstable. And I hadn’t even added any batteries. I added a wood layer and move the wheels out about 3 inches. The included bus bars for the battery connections were not wide enough to go across the right to left stack...

Regarding your 110V wiring comment, did you not see the pinout diagram on page 2 for the L14-30P using it for 240-V-120? It shows which terminal is not used for 120V.

I've purchased 2 Rosie's and am trying to figure out the battery cable path to the Rosie's. With 1 battery and 1 Rosie, it's pretty straight forward, but when doubling both the batteries and the Rosies, the amperage draw could be pretty significant. So with 2 Inverters and 2 batteries, I'm...

Thanks boB! (my favorite cartoon character when my kids were younger!)

I have question related to neutral wiring using 2 inverters AND bypass switches for each of the inverters. My inverter wiring diagram is straight forward, L1/L2 + neutral in from grid panel, and L1/L2+neutral out to load panel(for each inverter). But when I add the bypass, would I be...

I hope this isn't toooo stupid of a question. <sigh> I'm building my batteries and hooking them up to 2 stacked Rosies. Since I'm working with 48V and potentially 300A, when doing final connections, what is the safe approach so I don't create sparks/arcs in either wire to connections, or...

If kWh = kW * time and is 1 hour, if trying to figure out 1 minute, is it as simple as dividing the kWh number by 60? Yesterday was trying to get amps from Emporia, but that is all in kWh or Watts at the min / sec level. Or, if Emporia gives it to me in Watts, not kWh, then it's watts /...

Midnight Solar Rosie inverter. It’s their brand name. Search Rosie on this forum, and YouTube. You’ll get some entertainment.

I just bought a bunch of these from overstock.com affiliate. Price was $15.95 envyensembleemporium.shop/products/blue-sea-systems-5119-class-t-fuse-051198?currency=USD&variant_sku_code=5601903-0-0-0-0-0-0&msclkid=c9e674219a0c127e46d5121252e47b90
