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...

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.

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...

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?

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...

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

I did switch the follower to primary, and the Rosie made a lot of strange unexpected noise! So waiting for more guidance from support.

True split phase dual pole inverters. The two colors represent the different inverters. Bypass is true dual pole L1/L2 for each input. There is a box with a din rail for the breaker & the bypass and it has both ground and neutral busbars .

Sorry, seems I added confusion with the colors. They represent the inverters and not L1/L2. Rosie Inverters. True split phase 240V

It’s a push once for on and hold for 3 seconds for off (or at least it works that way for my inverter version). It’s handy when starting out and working through all the settings.

Yeah, and you see the attraction of buying a "real" Blue Sea t-Class at $16 <sigh>. I was searching for better pricing and google or duck-duck-go send me over the cliff to the fake overstock site. Pretty sure it was a scam since zero email confirmation. Fortunately I used an Apple Card...

I'm trying to figure out if I need 1 shunt or 2, or if I need to change my planned wiring to accommodate a shunt. Current scenario is 2 batteries and 2 stacked inverters connected via a busbar. In this configuration I'm confused if I need 1 or 2 shunts? Or, should I change the wiring...
