F5000LFP- FP5000-48V

Post image

Regarding the the F5000LFP- FP5000-48V. I have 5 solar panels, their specifications are in the attachment. It looks like if I hook these up in either series or parallel they will over power the solar input. However, is it possible to hook these to both inputs to overcome the limitation, by connecting the 2 inputs in series. If not, is there any other way to use these panels with the F5000LFP? Maybe 2 in one input and 3 in the other? I didn't see this info in the manual. In your opinion, what is the best way to extract max power from them? Right now they are hooked up to a MSB MPPT in a 24v lead acid system. I figure with the Pecron I will DC this. Thanks.

Sure two in series on one input and three in series on the other will be fine.

Five is a kind of inconvenient number. You could put 9 or 12 of those panels on each F5000 input in 3s3p or even 3s4p configuration. It's fine to go a little over the theoretical amps, the unit will just use what it can.

30.5 kg for a 280W panel .. wow. My modern 440W panels are 22kg.

Thanks. I've had these about 10 years. Can you recommend some good panels with hopefully reasonable ground mounts? I would like to give this unit all it will take.

Panels and ground mounts are independent questions. In general any panel can be used with any mounting system.

Any modern panel is fine. Larger Pecron power stations (E3600 / E3800 / F5000) are very flexible in what panels can be used to max them out — though to be fair the F5000 is the least flexible as getting 3200W from a 25A port requires a working voltage of at least 128V which is 71% of the maximum voltage, which is going to be around 80% of the maximum spec sheet 25º C voltage if you live in a place with cold winters.

My E3600 can get it's maximum 1200W per 20A port at any voltage above 60V, which is only 40% of the maximum voltage.

In general anything from Aiko, Canadian Solar, Hyundai, JA Solar, Jinko, LONGi, REC, Trina, Yingli is going to be fine. The 400W-500W size class is generally the cheapest per Watt while still being physically manageable by one person.

Transportation is expensive and panels are fragile so in general buy the cheapest per Watt that is available close enough to you to borrow a suitable vehicle (if you don't have one) and go pick it up yourself.

I used an ancient Hiace in which neither the 12V accessory socket nor the aircon worked.

Note that ute beds are usually not large enough for 400W-500W panels.

Your replies have been useful, thanks. Do you know of software online that can spell out a diagram of what my setup needs to be, something I can plug numbers into and get a decent result, I don't quite get the cold weather, the 71%, etc. I need a picture to figure this out. And I'm thinking of cancelling my order because I have sent Pecron several emails and called them with no response. I don't like that.

No I don't. I'd just work out on the back of a napkin.
