Specs below. The readings were taken in midday, direct sun in Greece. Appreciate temperature also has an impact. Max Power at STC: 220W Open Circuit Voltage (Voc): 26.8V Short Circuit Current (Isc): 10.2A Opitmum Operating Voltage (Vmp): 22.7V Optimum Operating Current (Imp): 9.1A...

Hey all. I have a question about an "underperforming" 220W portable panel (Renogy 220 E Flex). I completed a Voc (24.9V) and Isc (8a) test so getting 200W with a short/open circuit. My question is how much does this correspond to actual performance? What would you expect to see...

Has anyone had any more insight regard this? I had a 90amp motor (windlass for an anchor) that was letting chain out (so not much load on motor), registering at 30a max on the shunt yet it still tripped out my 200a JK BMS on SCP (SCP set at 5ms).

Thanks, will keep a lookout the next time it happens.

I have a 100amp fuse on the windlass so couldn't have been pulling any more than this. I guess the only parameter I can change is the SCP delay which is currently set at 1500us. Or is there anything else I can change? I get nervous over changing safety protections 😅

Hi all I have a recent instal of a 300Ah LiFePO4 system with a JK BMS on my sailboat. All has been working fine in the last week but today the BMS went out once on Short Circuit protection. I can't find anything on what causes or triggers this. Can anyone advise? I was running my anchor...

Hi all. I have just installed my DIY LiFePO4 12v 4S battery. I have full Victron charge kit (and SmartShunt) with a JK BMS. I just wanted to check the behaviour when the battery is fully charged. When it is fully charged (via a Multiplus on 230V shore power supply), the JK BMS cuts the...

Thanks all, sound advice all round. As some of you have suggested, it's all about risk, effort and time. In my case, as I am time limited (not got the luxury of managing a dispute), I will go elsewhere for now. However, I do feel Alibaba is suitable for those that are willing and able to...

How should the product be categorised?

I'm based in UK, but boat in Greece so looking for EU stock. Great advice on the paypal/CC option.

Did you just buy and hope for best or did you request anything up front?

What suppliers would you suggest in EU?

Hi all, I am a newbie to Alibaba. I have been lurking on this forum for some time. I was looking for some advice on what I should request from the supplier to minimise the chances of issues upon receipt. I appreciate that by purchasing from these suppliers, there's usually an element of risk or...
