As I've said before the cheapest thing for you to do is for You to purchase another 6 string combiner box so you can split your array up into two strings 1 for each pv input on your 12kw Growatt inverter. 1 combiner box would have 2 panels in series and 5 strings going to it and the other...

You should purchase another 6 string combiner box so you can split your array up into two strings 1 for each pv input on your 12kw Growatt inverter. 1 combiner box would have 2 panels in series and 5 strings going to it and the other combiner box would have 2 panels in series 4 strings going...

With a quick glance you can see for instance that at 0*C you should assume 110% of your arrays rated open circuit voltage, and at -25*C you should assume 120% of your arrays rated Voc.

Do you have the 150vdc pv array version of the 12kw Growatt or do you have the 250vdc PV array version like I have . I talked directly with the Growatt customer service office in California and they confirmed to me that my 250vdc PV array max voltage is per string and not a combined max voltage...

I might consider it

I never got any help on the bad charger I just put it back in the box and put it away

I'm getting 25 to 30 KW of solar a day pretty regularly now with my 6.2 kw's of solar panels. So hopefully I will see 50 kw and above pretty regular after I get the other 8 kw of panels installed.

Yea I don't see the 6000 watts very often it normally peaks at 5000 to 5500 watts for a brief time during the day if I have no clouds and my 600 ah battery needs a good bit of charging and I have a decent load on the inverter. Adding this new array should give me a possibility of up to 14,000...

The combiner box gives a good place to tie all of the strings into one place with a breaker on each string and then leave with only 1 run from the combiner box at the pv array to the inside pv breaker before going into the inverter pv input.

According to Growatt USA and Signature Solar I only have my 12 kw Growatt inverter running at about half capacity with my currant solar array. I have 24 - 260 watt panels running to my growatt inverter now 12 panels 3s4p on each pv string. I currently have it set up as 12 panels 3s4p on each pv...

On the Growatt if you have the Wifi dongle plugged into the USB port on the bottom of the Growatt inverter, the dongle covers the printer port where the cable plugs into from the raspberry pie with the Solar Assistant software. So I use a USB ext. cable to plug 1 end into the USB port on the...

Both working side by side

Here's a little extra information for our Growatt users that I thought some of you may be happy to hear, I have figured out that if you want to see both the shine Wifi app on your phone or computer along with the solar assistant app for your phone or computer, all you have to do is get a Usb...

thanks for your reply did you read this or do you have one of these and have it actually running it that way above 150 to 250 on each string I would love to have proof that someone has theirs up and running with 200 plus on each string. I don't want to burn my inverter up not knowing for sure.

Have you got your Growatt 250V Dual PV Input – 48V 12000T DVM-MPV 12kW Split Phase inverter and solar panels installed and up and running yet. I have the same inverter connected to 6.2 kw of solar panels been up and running for about a year and a half now. All is working very well except now I...

Ok thank you for pointing that out to me. I'm glad I ask before following thru with this idea. My Growatt inverter has 2 PV strings I was told that the specs were for both strings combined. I called Growatt this week and they informed me that the specs were for each string not the combined 2...

Yes I believe the HVAC contactor would work just fine. I don't know why I didn't think of that. And I don't think the Growatt is set up for AC coupling. I'll have to research that to make sure. I didn't think about that issue so if the Enphase is producing 240v power to my distribution box...

I am not grid tied so I will have to have somewhere for the solar power from the Enphase system to go. once the battery gets fully charged the Growatt will stop charging the battery but then the Enphase inverters want have anywhere for the solar power to go if there isn't enough ac load to take...

I am using a Batrium for my BMS on my batteries, I'm using the watchmon core with two K9's I know the Batrium has relays that can be programmed to do what I'm wanting to do but I need a good switch or disconnect that can be turned off and back on by the Batrium I would like for it to be able to...

I think all it has is a dry contact for starting a generator when voltage is low.

Hi I have 6.2 kw's of solar panels running to my 48v 12KW Growatt inverter and 600 ah of lithium batteries, it has been working very well for a year and a half now. But now I'm starting to run out of solar power to keep my batteries charged back up every day. I've purchased a little over 8 kw...

price on the batteries and can you post some pictures of them

Thanks for your reply I haven't changed any settings with the Victron connect app and I haven't changed any wiring on it. I got a good full charge on my batteries Sat.

Hi I am having some issues with my Victron 500a shunt, It has been working fine for about 6 months now. I have it connected to my 48v battery module and I have a cable going from my shunt to a Raspberry PI that has the solar assistant software on it to monitor my solar system and my battery. A...

Try changing browsers I was using safari on my IPhone and it did the same thing I downloaded chrome on my Iphone and logged in to solar assistant in chrome and it worked great.

Sold Thanks

It is a 15s bms but I have been using it as a 14s bms because they did not have a 14s at the time I think I either contacted battery hookup or JBD and they told me how to make it work but I haven't been able to get any information from them on it now

You may can but it has to be wired correctly with the bms wires for it to work right

Hi I've been using one of the JBD 100 a smart 15s BMS that I purchased from battery hookup. I was using the bms as a 14s configuration and it has always worked very well. But now I am wanting to uses this 15s bms as a 12s bms and I cant find any information on how to change this from the 14s...

What kind of issues were you having with your 12kw Growatt, I was losing data on my computer Growatt dashboard mine would not show any storage production anymore it use too but it stopped about 6 months ago, so my system would only show discharge which means mine was counting backwards on my...

Hi Dan I wanna say thank you and this forum for posting your experience about the solar assistant software and the raspberry pi. I just purchased the software and a raspberry pi, and I have now got the system up and running with my 12kw growatt and I also connected my victron shunt to it that I...

Hi Dan I just purchased the solar assistant License but haven't downloaded it yet, I wanted to ask you a question about being able to view my solar from my phone or my computer is there a app to download on my phone and computer or how do you view on other items like my phone and computer

Hi Dan will the raspberry pi work with the victron shunt connecting with the ve direct interface cable without any software added to the pi
