I'm not so sure 250 watts in 4s will not exceed the 150V voc of the CC. Perhaps a nameplate of your panel posted here may help or those with idea of the voc of 250 watts panel can help.

Your present 3s config seems to provide adequate headroom for your CC to handle the 48v charging and additions should be more of parallel going forward. I don't have much knowledge of the Fangpusuns though, but that's what I think obtain for most MPPTs I've encountered.

Edited: I see @ kardozy has same opinion as this.

ojeysky:


When I was using a 250w Panel max I got was 34v so I think you should be fine with 4S3P but 3S4P is certainly safer incase your Panel voc is higher than mine

who is using the UKA rechargeable fan?
bought it for my people some moons ago, now the switch has developed issues.
how were you able to repair the switch?. youtube is just showing how to replace the faulty switch

ojeysky:
Interesting sunny day, did over 3x of my array capacity, funny enough i didn't achieve any record instantaneous hervest but the cumulative is fantastic!

If the switch is mechanical, I think it should make it the more easier to replace, right?

Or maybe I'm just assuming sha.

Oshomo12:


My brother, pls never use that figure to work. Use the VOC on the name plate. If and if u just for a second or two, u see 38v, what happens after that?
I have seen that quite well on 255w trina

Users of inverter ACs here, your input may be required.

FrustratedMonk:

Chris is right. That AC only cools on cold nights. I had to give out mine and use a non-inverter AC for peace of mind.

So I got to confirm the consumption. It only has DC to DC cables included. It does not come with AC power pack included unlike the Qasa AC/DC standing fan (the type Ojeysky has in that picture) that has both AC power pack and crocodile clips to DC plugs included. So I used the power pack included in the latter. It's rated 230vac 12vdc 2amp plug.

At speed 1 - 9 watts
At speed 2 - 11 watts
At speed 3 - 15 watts.

It blows air impressively down a 9 feet ceiling at all speeds.

How many pieces will give a 24v setup. Gud morning.

Earthrealm said his works just fine.

This one we are getting different reviews. Na wa o.

odimbannamdi:


Which app/software is this? And how does it sync to your components (batteries, inverter, panels, etc)

kadorzy:


Simply install your inverter AC in an enclosed space you will sure achieve the balance between optimal cooling & lower power consumption.

If you need more cooling, you have the remote to switch to full power mode.

(From Thermocool 1hp user perspective).

Price and source of purchase?

ceaser:


Thanks.

What's approximate size of the room d'you use it for?

ojeysky:


It's the mobile version of emoncms that basically reads data from the emoncms on on my raspberry pi, the emoncms receives data from solpiplog for processing which inturn hervest the raw data from my pip inverter and BMV.

ojesymsym:
How do you set up this raspberry pi, I get idle pi 4 when de idle that I can deploy. Any link to a tutorial?

I hope I don't get picked up by NL bot here is the link to the solpiplog with all the instructions: https://github.com/njfaria/SolPipLog

Good day guys, I have LiFePo4 battery, I want to ask how many watts solar panel will charge this battery efficiently even while I use it and it will still be charging

I like the fact that the inverter did not seem to increase its fan speed at that load, though since it's 5kva, the load would be about 30%, nice to have inverter I must say!

Dam5reey:


What is your Daily usage in Watt hours?

Example mine is 4kwh, So I must be able to generate 5-6Kwh daily if I rely only on Solar.

Penuelseun:
What is the capacity and voltage of the battery?

ceaser:


Is that battery LiFePO⁴ or Li-ion 18/650/s?

Other specs of the pack?
