I bought this charger over a year ago, but only now I started to test it... I'm still in the process of building a 14s (18650) - so I just made a small test-setup with a 14s2p, just to try. I did try to set the float voltage about 3v lower than the charge voltage, but I think the charger stay in...
(y) glad to help and thank you for bringing this up - I also learned a lot about this charger!
I would like to know how to set the battery correct when using Lithium - I have a 48v 14s but I don't know how to set this so the charger don't go in 'float-mode' - do you know?
Nice! - so we have:
1. PV Voltage 3300 = AA01000203040100E40C5B
2. BAT Voltage 1666 = AA010002030403008206C1
3. Charge Current 2090 = AA010002030405002A0815
4. Load Current 2200 = AA010002030407009808A5
5. Load Voltage 1666 = AA010002030409008206BB
that should be it, I hope :)
Now I think, to set the 3300 the HEX code would be: AA01000203040100E40C5B
Because: AA0100020304 and then 0100 for wPvVoltRatio and E4 0C is 3300 (just reverse 0CE4 is 3300)
If you try this, it's on your own risk - please don't blame me if something goes wrong... ;)
if this: AA 01 00 02 03 04 03 00 6C 06 D7 is 1644.
then you have to change the 9th and the 11th - meaning the 6C and D7
if you add one to 6C then you have to subtract one from D7 ie. 6D and D6 (1645) and 6E and D5
did you try with the 'reset / bug' code?
just to get some standard values in the 5 fields and then try with the
to set your voltage
It would be nice if...
ok, did you also look at #30 - there is a link to a file and in that file there is a document called SolutionsEN.doc - here they write a hex code, looks like a 'reset' code.
#41 'rcuetara' show hexcodes for the voltage.
So if: AA010002030403006C06D7 is 1644 then:
Hi, I just saw this other version:

If you connect a battery, then in the menu - you set it to battery mode and then battery start Volt, battery off Volt and the amount of Watt you want to take from your battery and add to the grid. I am currently playing around with an Arduino / ESP8266 - then it will be possible to add some...
Today I connected the powermeter/limiter to an RS485 -> USB to serial converter on Windows and made quick and 'dirty' C# app. It reads the data and shows the watt in the console. I just want to share this code in case someone can use it to get startet or something like that. This...
This is a reply to your previous post. The idea is good as long as we don't have a smart meter! I'm in Germany too and we still have the old meter with a disc. I looked at the 4 Channel module and it looks good, it collects the values from the 4 inputs and returns the mV (watt) or a int value...
Look at the 4th page - it's from the book 'DIY Lithium Batteries' by Micah Toll - It's a very good book!
ok, so - don't think about the amps when you make something...
I would say that a fuse on the red wires should be small, like milliamps - because you only want to allow a small current for equalizing. I don't know this exactly. This is the boards I was talking about:
In this video he shows his trace-fuses. The cells are in series and he has a SMD fuse...
