Hello Solar Geniuses, So one of my Growatts isn't using all available solar and I can't figure out why. You can see on the main window that it's showing 1749w solar, an 1892w load and it's pulling 412w from the battery. But if you look at the info window at the bottom, it's getting 3190w from...

I have the Eg4 6500 and it's been issue after issue with this thing, including this terrible app. I guess I'm spoiled by Shinephone but this Watchpower seems to lack basic information. How do I see how much power is being drawn from the grid? It shows voltage and frequency but these values are...

So what kind of settings do you use them? Specifically 12, 13, 19, 20, and 21? I have the 48v model. Do you have separate charger rates for 19 and 20? Right now I have them both at 56.5. The other day I changed 13 (when inverter will switch back to battery?) from 53 to 55 and t seemed to...

Excellent! Thanks for that.

I haven't had a laptop to flash them until recently so I still have to try that option. I've been trying to work with Signature Solar on some solutions but I just can't deal with their lack of customer service.

I'm using us2 at the moment.

Thank you guys for the input. It is a 48v CC. I'm just worried that the extra charge controller might cause a conflict with the existing inverter.

I have a couple of the Growatt 3000lvm inverters in series with four 48v 100a batteries. Because I'm using DIY batteries they don't communicate with the inverters and it ends up using some battery power during the day. I've gone around and around with this issue and, long story short, I have a...

The inverters can be glitchie if they aren't communicating with the BMS. I have a few of the Growatt inverters with DIY battery packs and no BMS communication and they are constantly using my batteries during the day when they aren't supposed to. A BMS that was communicating with the inverter...

Yes, I've seen people discuss this as a possible resolution for the issue. I saw someone mentioned in another thread that switching to USE allowed them to set #19 & 20 at different levels and they set #20 at .5v less than #19, which seemed to work for them. I tried it once before but it got...

I have the same setup as you describe with the two 3000s in split but they both have to be reset every morning to get them to detect the panels and then one of them starts using the battery once it's charged. It's extremely annoying. I decided to try going single phase thinking maybe the...

These inverters are supposed to be able to use solar to power loads as first priority, while charging the battery with secondary solar, then saving the fully charged battery until solar runs down. The whole point in having batteries is to power loads without the sun, but we can't do that if the...

I am having this same issue. I haven't solved it yet and it's super frustrating. I don't think it's a settings issue. It might be a firmware issue. You can contact Growatt America and they'll send you the info to do a firmware update. I haven't done my update yet. I'm scared...

Okay. And it looks like it's hard to find a single phase panel to use for the ac output so you said I can use the split panel and a jumper? I use 8awg stranded wire for the ac output. What do you think?

Okay. Just checking. So single pole input for single pole output and split pole for split pole. Thank you

It would be so much simpler This is good stuff! Thanks. So should I be coming in from the same pole even if I stay in split-phase output?

I don't suppose anyone on here lives near Tucson? :)

I knew someone would ask :) I'm not going from 240. I'm going from split phase 120 to single phase 120. One of the reasons is so I can jump past the 3000w point and not have to worry about the surge. The other reason is because my inverters are glitching in ways that Signature Solar hasn't...

Wait, I currently have each inverter on it's own ac input coming from two 30a breakers. Those two breakers are on alternating poles at the main panel. What needs to happen here? I need to feed them both from a single 60a breaker and 6ga wire? Or do I just need to move both breakers into the...

Hey Bud, They are the spf3000tl lvm 48p models. They're made to connect in parallel split phase, single phase or three phase. The technique to combine them for single phase should be pretty standard, I just don't know what it is. The manual just shows a stick diagram of the two output lines...

Hello Again Folks, I'm going to wire two 3000w 120v growatt inverters into a parallel 6000w 120v unit. What does that wiring look like at the ac output breaker box? I currently have it in split phase with each unit powering one busbar in the breaker box, with two 15a breakers going out of each...

Also, this is basically what my multimeter does, right? But the multimeter only goes up to 20a and the clamps use a different method.

What would short circuiting them look like? What do you mean?

I have another 7s2p system that puts out about 230v and 15a in the sun. I know this because when I put my multimeter on the terminals it ALWAYS reads what the panels are producing, regardless of what the inverter is using. If it's pushing 15a but the inverter is only using 6a, the multimeter...

No that's not what I'm saying. I can put the clamp on the cable and see what the SCC is drawing. I don't want to know what the inverter is drawing, I want to know what the panels are producing. What I'm saying is the inverter is pulling 9.3 amps total (7 amps to power the fans and 2.3 amps to...

It does show total voltage being produced but not total current. If it's using 9.3 amps to power the load and charge the battery it's going to read 9.3a from the panels. It will pretty continuously read the full 100v throughout the day but the amperage reading will fluctuate based on the load.

Yeah it's an ac/dc meter. By active current I mean it's only reading the current my inverter is using. I'm referring to that as active current. As opposed to the total current my panels are producing. So if my panels are producing 45a, but my inverter is only requiring 10a to power the load...

It's the spf3000tl lvm and it shows the voltage and current being used. It doesn't tell me how much is being produced (that I know of).

Hello Again Folks, This is one of the most knowledgeable groups of folks around so I'm back with another ridiculous question. How do I measure the total current my panels are producing if it's over 20 amps? I picked up a clamp meter that reads up to 600a but from what I can tell it only...

Sorry duplicate message I don't know how to delete. Please ignore

I am currently dealing with this same issue and I'm wondering if you were able to resolve it and how?

It's the second. The BMS comes programmed with the AH size set to 50 and I can't get in to change it. I don't know if that has any effect out not. I have two packs with simple Daly BMS and two with the ANT BMS. The ANT both connect to Bluetooth but the app will only connect to one of them...

Hello Again DIY Community, If a BMS is reading a 48v 100a battery at 50a, will that prevent it from fully charging the battery? I have a stack of 4x48v 100a lifepo4 batteries (19.2 kwh) and I can't get one of the ANT BMS to connect to it's app and it comes default set at 50a. My inverter says...

Okay. So I hooked up the charger to all 4 batteries and the inverters fired up. I removed the charger and everything stayed on and the inverter is charging. Thanks for the guidance!

I'll give it a shot. Thank you
