Aims Battery Charger 12V & 24V Smart Charger 75 Amps

[rdolinski]

Hi All, hoping someone can help determine the Power Factor (PF) of the Aims CON120AC1224VDC. This is the 12/24v 75A smart charger.



If you have one of these units and a Kill-A-Watt can you please measure the input current, input voltage, wattage, VA and P.F. while charging a battery at 50% and 100% charger output.

​

TIA!

I just got this charger wired up this afternoon. I am getting my batteries down below 12v and will do a charge test for you.

Love the rig! Looking forward to the results!

Charger set to 100%. Using the 0/1 charing profile (Generic Flooded) as despite the manual voltages - I find this best matched for my batteries (28.8 bulk & 26.8 float) which is almost perfect for my Firefly g31 carbon foam batteries (https://azimuthsolar.ca/wp-content/...ed-2020-Firefly-Users-Manual-G31-4V-450Ah.pdf)

In moving the currnt control dial to 50% - it seemed to drop the current to close to 10A on my clamp meter. PF went to 0.993.

Wow, that’s a fantastic power factor! Im really glad to see that! Must be some active correction.

What do you reckon is the overall conversion efficiency?
1131watts in and 1123 out (28.8v x 39A) seems a little off.

I'll have to play around a little more to see. Keep in mind, both my kill-a-watt and clamp meter are cheap amazon purchases

 

[rdolinski]

Well based on your power factor measurements I think I’m going to get one of those chargers.

So far I am super impressed.

Great units from all I have heard but watch out for this seller... https://diysolarforum.com/threads/a...deal-with-aryaco-on-amazon.20614/#post-241282

I have to say over the last few days it contiunes to preform fantastic for it's price.
Tho, I may end up selling my unit.

I ended up buying a Victron Multi-plus 24/3000/50 this week.... So I won't have much use for it anymore...
