Thanks for your Time

The BMS shuts off at 55.4 V

Just Remember that if you go with SMA the Sunny Boys need to be set to OFF GRID. Also i have found that Trophy Battery (Dan Keaton), has checked with his engineers and tell me that his batteries work with the Sunny Islands Com Protocol in a closed loop.

Awesome Thanks

Looking for advice and may seen like a vary odd question. Would it make sense to combine my three 220 48 v trophy LIFPO (33Kwh) in a closed loop to my 2 SMA sunny islands via a bus bar to my 17 KWH 332 ah 48 v Big Battery kong with a seperate AC dedicated 48 v charger (not connected any way to...

I had the same issue with the Vbat Max. Hedges suggested ti lower the battery setting to 46 volts and it helped as it creates a wave of influx power , the lower voltage give the battery space to keep from hitting the VBat Max. I have a Big Battery Kong elite in open loop and it does not lie to...

I have contacted EG4 several times and they say their EG4 LL work in closed loop with Sunny Islands , just need to download the battery protocol.

Hello Could somebody who is familiar with SMA tell me which of the SMA data manager would be required to monitor your PV input and out put for local only. I just want to be able to see what is going on in my system. I have 1 SB 6.0 US -41 (NO W-LAN) and 2 SI 60/48. Just need to be able to...

I have been looking at the EG4 Pro to work in closed loop communication with my SMA SI 60/48. I did see another member id get them to work with there SI. Is the New Ruixu Lithi 2-16 the same as the EG4 Pro, they look identical. Riuxu did tell me they work in closed loop with SI , just curius if...

I have 2 Sunny Island 60/48 and found Fortress Power have Batteries that they say work in closed loop with SMA I have a Big Battery Kong Elite 17 kwh that does not have closed loop capability and does not work very well as SOC is all over the map. Will have to sell the Kong and get the fortress...

I have a Big Battery Kong Elite 17.5 Kwh 48 V LIFPO that is only two years old for sale.

Not sure i just got mu Sunny Boy set to OFF Grid to supply power to the Sunny Islands thinking that was the issue now the Battery is hitting VMAX.

Awesome thanks

I think the company is GSL direct from china. They have lots of different batteries and is hard to get a straight answer and price and they annot provide doumentation that they work in losed loop with SMA 60/48, only a picture with it connected to the Battery.

LiFEP04 i think its the DC as the Battery is 100 percent and the sunny boy is charging

My Sunny Boy only has Hard wire Etherner (NO WLAN ) capability but it does work ,will keep tinkering would really like to be able to keep this Battery instead of starting over. Thanks for the Input

Looking for some help. I have a new system Completely OFF GRID (Generator back -up )with a sunny boy 6.0US-41 and two sunny island 60/48 inverters. Do i need a grid guard code to set the sunny boy to off grid mode only and is the RS 485 piggy back cards required for both units to communicate...

Awesome thanks ,in prosess of getting grid guard code, Have heard that Fortress batteries work in Closed loop With SMA any knowledge of Fortress

It shows up on the Master but is says S1 which would be the slave ??

I'm OFF GRID and had alot of issues with my Bunny Boy not being set to OFF Grid, Thanks to Hedges it has helped immensely. Now I'm looking at Trophy Battery to do Closed Loop Coms.

I have 2 60/48 and the approved batteries are different on the SMA website, I thought with SMA it would be esier as they are all from one company, but the SMA protocole seem to be a Pain in the A@#.

No i only have the Sunny Portal as now for any Monitoring but when the Generator is connected the charging amp slowly drop as the battery reaches full.

Only Password i know of is the installer one sum of running Hrs

Hello , Would anyone have a SMA Data manager they would be interested to sell, Im looking for the M-lite Thanks

Franken Solar have a RS 485 Core i Module for the US 41 different that the Sunny island glad that they are not required Thanks

332 Amp LIFPO4- 48 volt. Bought in late Sept and installed Dec 18th. One month usage, Too small for my system. My SMA inverters do not communicate with this battery. This Battery will work with Sol-Ark, Magnum, Outback, Growatt and many others. Very large capacity battery at 600 lbs...

In the process of getting a Grid Guard code and will have to sign into the User interface and follow the Promps. Only way i have to access the SB

Thanks for the help i will keep trying but it shouldn't be this hard to get this fixed. Iv tried SMA support but they haven't responded in over three Weeks. So thats why im here with other DIY. Fun Times ..

Hello All Has anyone used Trophy Batteries LFP in a closed loop with Sunny Island 60/48 Inverters. I have contacted Dan at Trophy Battery and he and his engineers said that they just work. As i am aware SMA only have a small list of Litium batteries that are approuved and Trophy are not on the...
