If I have a nearby lightning strike that creates a voltage spike in my PV cables I assume that connected devices that are rated for a maximum voltage of 250VDC will be destroyed if my SPD has a Uc above 250V. If I understand this correctly then I thought I should have an SPD with something just...

I looked at the specs from Midnite but I don't think it will protect my MPPT. If I understand SPD's correctly I believe I ideally need a Uc <250V.

Hello all. I am struggling to find a suitable DC SPD that will work well with Victron 250 series of MPPT. My PV panel string voltage open circuit is 212V and expected max cold temp open circuit 235V. Victron 250 series MPPT's have a hard voltage maximum limit of 250V. Can anyone suggest a...

I think you need to look at the 250v line of victron mppts. 5S2P setup if you want a single device.

I looked at dc rated NH fuse disconnect devices but in the end settled on a 600amp meadotech switch to isolate the 3 victron multiplus. The multiplus's will connect to the top distributor. The switch fits perfectly with the lynx bus bar setup. The switch cost was £470.00.

Hi. I have 30kW of pylontech that will I connect through Victron Lynx devices (power in, shunt and distributors) for a home ESS. Each of the 6 batteries are wired to Lynx power in individually. I have a class T fuse between lynx power in and lynx distributors at the shunt but still need to find...

Should the red SW on a Pylontech US5000 battery pop out after being pressed? Mine stays in. Is that normal? I thought the SW button was used to switch a unit or group off before using the master toggle switch.

I hit post tooo early... wiring unlimited page 27 illustrates the correct lynx device order.

This image illustrates the communication and wiring to create 2 battery banks. You could also have turned this into 8 separate banks as was discussed. The comunication wiring remains the same. Here's the link to the topic at Victron...

It would seem that there ought to be a compliant anti islanding anti export hardware device that could be installed upstream if Victron can't get their larger Multiplus-II certified. I saw the Ziehl UFR1001E device but unfortunately I don't see a Danish certificate, yet other Nord Pool countries...

Thanks for all of the info. Your setup is impressive! I was in looking at the Multi-II 48/8000 or 48/10000 in 3 phase. I wonder why the apporoval list stops at the 5000. Do you know, If I do not allow export then are those lists irrelevant?

Hi da9el84 Is your system up and running? Which components did you install for the mppt and inverter/charger? ..any great photos? I am also in DK. I am building a home solar system with the aim to keep all generated power on-site by charging up a battery bank first and then afterwards extra...

Well good news has arrived. BLS Battery Industries has wrote to me that there should be no problem installing on side for their cells.

Well I have decided to shelf my overkill bms's and I will buy a REC active bms (victron compatible model). It is able to communicate with the victron gear thru the canbus and external relays can be used as well.

It's interesting because some "drop-in" 12v LIFEPO4 battery companies allow for any position mounting and others have restrictions. I just wish the manufacturer would provide a data sheet with their recommendations. I can live with a reduction in cycle count but if for some reason it's a safety...
