Hi, Thought I would post a quick update on my whole house system in case anyone is considering taking the plunge. I installed 10kW worth of solar panels last June. I also installed a Growatt 12kW Inverter, and 55kW of Batteries from Signature Solar in Texas. So far the system has performed as...

Well the beast is on the wall. I will update with a picture later in the week. I mounted it with 6 3/8 x 4" concrete lag bolts to make sure it does not come off the wall. I also added 3/8 Chains to Eye Loops and a 4x4 just to make the wife feel better. Overall the Grow Watt unit is built very...

Hi, I have a 10ft basement, and in order to route circuits from existing panel I raised the sub panel, and Inverter to allow me to not have to splice with for each breaker circuit I am moving. The main panel was at about 4-5 feet on the wall when I built. I have a wireless monitor so I can get...

I bought one from dreamsourcelab.com. It works very well, and is built like a tank. I will capture some data traffic on the Battery Comm. interface when I get time and post it.

Thanks Steve_S for providing the information. I will dig into it. I am still trying to digest why some system configurations will only run with PV inputs 100-300VDC. I realize the obvious that higher voltage means small wire coming in, but I would not think most would be more than 100-200ft from...

Thanks a bunch for the input.

Hi All, I finally bit the bullet and ordered a couple GYLL Batteries, 25 REC 315W Panels, and a Grow Watt 12KW 250V Inverter. I am still in the process of installing everything, and trying to figure out how to mount this 12KW on my basement wall. It weighs 165lb., and feels like it could start a...

Hi, I realize that there will be 60-80A coming in. Most likely I will need 6ga for my distance. I just got a quote from a guy in Texas that seems pretty knowledgeable on stuff, and seems to carry decent stuff. Has anyone ever heard of signaturesolar.us? He gave me a quote for a 12kW Growwatt...

Hi, Sorry for the late reply. I ended up having to update my Firmware via my laptop to fix a few issues. the version they provided from Signature solar was GW511.03 from back in 2021. I would check to see if there is a update newer before I tried to update my unit. I must say after I did the...

Anyone looked at the new Communications Hub EG4 is selling to handle battery Management yet? Maybe this would solve the communications issues between the Growatt unit, and the EG4 batteries. I am going to reach out and discuss it with them...

Hi, I have a existing system that I installed two years ago. I have 5 groups of 5 panels each that each panel is 40V VOC. This creates a 200V input per group which keeps me under the 250V MAX on my Growatt 12KW Inverter. I have room in my cabling system to add one more group. Signature Solar...

Thanks Guys for the feedback. I am using a pulley system and carabines for climbing. To hook it all up I used 3/8" chain. So far the Math works out so hopefully this weekend when I get some Muscle I can get this bad boy on the wall.

Hi, I am planning on using the 12kW Grow Watt unit. It peaks at 36kW they claim. I am still digging into MeritSun just because I really want a plug and play system. Not sure I want to tackle building my own batteries. Thanks for the feedback.

Has anyone else had a issue getting technical Support at Signature Solar on the phone? I have been trying for a week and a half to get someone on the phone to help me with getting my Inverter back online. I have also sent a couple support emails as well. I had a Lightning strike that I believe...

Hi, Thanks for the responses. I have also been waiting about 10 days for a request to get a firmware update. I had to replace my controller with the backup I bout a while back. The firmware is older and not working correct so my system is crippled at the moment. When I first purchased my...

Well I am not the sharpest tool in the shed, but I know my way around Engineering and Electronics being a Hardware Design Engineer. I also have a degree in Computer Science as well. All I need is where to find the firmware updates and I can handle updating the TI DSP. I have spent about 35K...

Thank you all for the suggestions. I am still looking into the issue. I also have noticed that since I added more batteries the low voltage trip does not engage when some of the batteries fall below 10% threshold because others are still above the trip limit. I am not sure how to make them all...

Thanks schmism, I have no issues doing a battery build myself. The newer 12kw growatt unit is suppose to handle AC load startups better now. I am still researching it. I had not planned on using the AC on my system, but if it can handle it that would be a plus. I have a 3ton and 2.5ton split...

Hi, I have been pouring over different Inverter/Charger units, Batteries, and other hardware trying to get a feel for what I would need for a whole house backup system in the event I loose my grid. I can't seem to get a clear idea on what is needed besides the Inverter/Charger...

Hi, I have a whole house system I am still working out the details, and ran into a issue with one of my batteries. I have 12 EG4 batteries and a 12KW Growatt Inverter. Ten of the Twelve batteries are GEN2 with a display. One the last three I purchased back in July I noticed that one of them...

Thanks for the feedback. Aren't the 15S more for battery storage? I guess I am not sure the difference between 15S and 16S. Will have to look into it.

Imagine this stackup lying horizontal. MIT came up with the idea in 2012 on stacking vertical, but I have seen a few installs where they lie the other way. My thought was to mount rollers on the sides of the panel and put it in a rail system. That way I can drop them flat if need be...

Hi, Thanks for the suggestion. My Inverter is a Growatt 12KW Off Grid unit. I doubt EG4 has what I need but I will look. Tom

Hi Guys, I am debating mounting my panels on the ground in a Zig Zag fashion. I have seen this done around here, and I guess it is a new concept. The issue I am worried about is I get high straight line winds in the fall when storms come. I was thinking about mounting rollers on the panels and...

Hi, Thanks for all the replies and information. In looking over the documents I found yesterday it seems to indicate that the PV panel input must be at least 60V. I plan on using 48V PV panels so I was wondering if anyone knew 48V panels would also work or if they had a work around. Just seems...

Hi Guys, Thanks a bunch for the help and suggestions. Attached is a picture of a cheap Inverter I found. Although I will go with a better quality unit the picture represents what I am trying to accomplish. The picture does not include my sub panels I will have to put in, but it shows the power...

Hi, I am in the process of getting a whole house backup system installed in the next few months, and was wondering if anyone had some input on the equipment listed below. Any thoughts or suggestions would be greatly appreciated. My goal is to run 90% of my home off this setup excluding the AC...

Hi, I was wondering if anyone had any experience with this manufacturer, and if so how well do they work. I was also wondering if there might be a manual available somewhere as well. I am looking for a simple solution I can mount on the wall, and not have too much maintenance. Any thoughts or...

Hi All, I am new to the forum, but have many years experience in Electronics and Engineering. I am looking into purchasing a full home system to supply around 10KW if needed. I would like to minimize my space and clutter in the basement so I started looking at all in one units. I found this...

Hi, Meritsun got back to me. They have been very responsive so far. Below is the battery information they shared. Wanted to post it in case someone else was interested. Overall I think their system would fit my needs, and the cost/Kw seems reasonable. It came out to about .265/W if I do the math...
