Hi, I am looking at adding a victron 100/30 to manage one of my strings. The VOC from my string would be 100.68V. Would that extra 0.68V fry or substantially shorten the lifespan of the controller? The 150V version is almost twice the price!

Hi All, I have a Growatt 5000ES which I have been running with a SOK 48V server rack battery (5kwh) quite happily for 6 months. I recently added a second identical SOK battery and i am now seeing some issues. The batteries seem to sync up and communicate ok. They charge and discharge together...

Hi All, I have ~6kw of panels in 3 strings wired in parallel going into my growatt 5000es. The total voltage of my panels is around 170V. I have noticed recently that i am hitting the 22A limit on the growatt and am therefore losing out on potential power. Wiring more panels in series to boost...

Hi, I have a 48V system with a Growatt 5000ES and a SOK 48V 100ah (5kwh) server rack battery. I have just purchased a second identical SOK battery. I know how to hook them up with CAT 5 cable and set the address etc but I was wondering about the state of charge differences between the two...

Hi All, I have been having some issues using a pair of 48V 5kwh SOK batteries with my Growatt 5000es. The batteries were not balanced and so I removed all coms and ran the system with manual setting values for a few weeks. Things appear to have improved but I still have some issues. When the...

Hi All, I am hitting the Amp limit on my Growatt 5000es so i have decided to move one of my 3 PV strings to its own charge controller. I plan to buy a Victron 150 | 30 mppt charge controller. My Growatt is using ethernet communication with my two SOK 48V server rack batteries. Program 52 if I...

Hi All, I have a Growatt 5000ES which I have been running with a SOK 48V server rack battery (5kwh) quite happily for 6 months. I recently added a second identical SOK battery and i am now seeing some issues. The batteries are frequently not balanced and both charge and discharge at different...

I have 8 panels @ 40V and max 10A and during the day 4 of the panels are likely to become shaded but the other 4 should get full sunlight all day. Obviously if I parallel all 8 panels into a single string then the amps will drop for all panels when the shade hits. However if I split into 2...
