Thank you! Can you please help clarify though if my single string system really needs a fuse as the panels are in a single string outputting 13 amps vs series maximum fuse amps on the panel specs is 25 Amps and do the fuses help in arc issues?

Here's my Solar panel specs. I guess it won't hurt to go with a fuse. It's putting out 12-13 amps so 16 amp fuse or 20 amp fuse rated @ 1000 Volt should do?

I need a Solar/DC Disconnect Switch for my single string system; as per the VOC and ISC Amps, I should rate it @ 1000 Volts DC with 16 amps. My inverter is pulling between 700-800 volts with Amps between 10-13. As per spec on IMO website, I can go with either SI16-PEL64R-4S or the SI25-PEL64R-4S...

Unfortunately, over here in our country, while shift to solar is rapid, the safety requirements are really zero and every installer or company is just using Chinese two pole DC breakers as DISCONNECT! No known name brands either, they are knock off Schneider mostly here. The DC cable used in...

I'm assuming RSD will be very expensive...

Appreciate your response. Can you please confirm though if I really need a fuse or a breaker other than DC Isolator/Disconnect Switch because Maximum Series Fuse Rating for my Longi Explorer 585 W is 25 Amp and since all are connected in series, entire string is generating about 12-13 amps. I...

Thanks, I don't want to go with the solar connector ones while the one you mentioned from IMO is model no. SI32-PEL64R-4; if you see the list I have uploaded above. There is no rating for even this particular model under UL508i rating while under the DC21A rating, it is fine for 13 amps @ 1000...

My residential 10kw system went live today, with Growatt on-grid inverter using Longi Explorer 585 watt panels x 17 so a total of 9,945 watts in series. The installers set it all up as a single string with the inverter so the voltage is peaking at around 730 volts with ampere between 10-13 amps...
