Did any one have any luck repurposing these batteries.? I have been given 2 x 2.5Kw Sonnen batteries which I have added to my Growatt battery system. Problem is they don't stay on! My Growatt batteries are connected to Growatt inverters and Communicate perfectly. The Sonnen Batteries have all...

Hi All, Have an existing system that functions well with 3.5KW solar array, 5KW growatt inverter (SPF5000ES) and 5KW Lifepo4 Batteries. Would like to add more Solar Panels (another 3KW) but the current array is on a roof that has no space left (North facing), so will need to install a new...

Yes. After the 2 output breakers (25amp) into 1 breaker (63amp) that supplies my house.

Yes, both inverters need ac input with earth and both inputs should have seperate breakers. There are 2 cables for each inverter for parallel setup. 1 is data communication and the other (red and black) is named current sharing but due to their small wire gauge they can not share much current...

The diagram for connection is shown in the back of the instruction leaflet. It’s quite straight forward. The connection cables come with both units, 1 set in each box and both are needed. If you don’t have the instructions you need it for the rest of the setup anyway. It’s downloadable from...

Reply I got from growatt which i followed: 1. I believe both neutral are connected before each individual breakers. 2. Yes you can start them up withouth AC in connection.

Hi All, Have been running 1 Growatt SPF 5000 SE off 5400W of panels now for over 5 months. Have decided to expand my system to 2 inverters in parallel and have some questions that I can't find answers to. New system: 2 x Growatt SPF 5000 SE both powering same loads using parallel kits, 16 x...

I have 13 set to 54v and 12 set to 50v. Both these settings at irrelevant for me. My system is sufficient for my power usage so while I am wired to Utility power the breaker is switched of. I have only used utility once to recharge my battery when I accidentally left my freezer open over night...

No Problem. Do I understand you correctly.. You have removed your BMS? and operating without it? I think you should set your "20" float voltage at least 1v lower than your "19" charge voltage. Otherwise you risk micro cycling your batteries which is not good for them.. If you want to charge...

thanks

Thanks...Where did you get the ISPtool?

The Growatt SPF 5000ES will not communicate with the Daly BMS. I have my Growatt Battery Type (05) set as "US2" Then use the settings in 19,20 and 21 to regulate the battery. The most important settings are 19 and 20. I ended up buying 16 x Eve 230Ah batteries with 250Amp BMS. (Screen shots...

sounds good. Are you able to upload the .bin files here?

Hope its not an April fools joke :) F030_SK041.06_20220104_A.bin

You are correct. My inverter tops out at 18Amp. Voltage floats around 190-200Vdc. This is why the highest Watts I have seen is about 3500-3600W (200x18). Like I said before, this won't be a problem for me when I install a second inverter, but this is about 2 months away while I am building...

Interesting.. Doesn't show that in my manual. (attached, on page 39, same table) My panels are 540w and have 10 so max 5400w. Highest watts I have seen on the inverter is 3500w but I am in Thailand and have not seen summer on these panels yet. Have not been looking at the Amps on the inverter...

Where in the manual does it state the Amp limitation? I'm sure I saw it when I installed mine 4 months ago, but my PV array is 5S2P, each string is 230Vdc and 12.97Amps so total Amp input is almost 26 Amps, well above 18 amp or 22 amp.

mine is on the same version. installed about 3 months ago. no idea how long the seller had it in stock. All the internet searches I did a month so ago say it is the latest version.

Have been in contact with the Lazada supplier and he has told me that there is no software provided with the purchase. Is there a generic software for communicating with BMS's? or Does anyone have a contact for support at EVE Energy Co., Ltd?

I am in Thailand so this is the website I will buy from https://www.lazada.co.th/products/batterylithium-lifepo4-48v100ah-i3136810461-s11685251041.html?spm=a2o4m.searchlist.list.1.78796fa3ogwTId&search=1

Has anyone had any experience with an EVE48100 server rack mount battery pack? They are made by EVE Energy Co., Ltd same company that make the EVE cells. Unable to find much info on the EVE website but did find a PDF instructions with an internet search. (attached) Would like to know if anyone...

Hi All, About to order the components for my first battery build and want to make sure I am ordering the correct BMS. Inverter/Charger Growatt SPF5000SE (Spec pic below) Its maximum solar charge current is 100a and is connected to 5400w PV Array. So should get 100a @ 48v in full sun...

Hi All, Have recently installed solar 5400w PV array with Growatt SPF 5000 ES inverter. System has been running well for 2 weeks without batteries. Now looking for some battery storage. I live in Thailand so options are limited. But looking for a power wall at a reasonable price. Ones...
