Hi, Also if available in Joburg will need those please to equalize batteries. Willing to collect or even pay for courier costs if not in Joburg

Hi, Sent PM

@John Know Hi, Just as a maybe please check dip switches on batteries 1st/master 1 should be on and 2nd/slave 2 should be on

Dip switch on master battery only needs to be 0001

Hi, Does not have to be even. Main thing is DO NOT exceed 450v per sting

Just my 2 cents worth put 4 North facing, 3 West Facing and 3 East facing, connect 2 north facing with 3 east and the other 2 north facing with west coz it's what i did and works perfect

From what I know they cannot be paralleled, they are stand alone machines but stand to be corrected O!! Im glad your issue has been resolved.

IMO I would install 5x 600w and 5x 600w to make both mppts work equal, this way inverter will b more efficient and sell the 2 x250w

https://powerforum.co.za/topic/4839-axpert-error-04-with-pylontech-batteries/ check link above. Hope this helps and you come right

Should be fine, if done correctly

I think : Microcontroller Unit IMO Don't fix whats NOT broken

@Andry91I would like to welcome Tom Cunliffe to the Sunsynk UK Team Maybe contact this guy and see if they can assist with a sunsynk solution for you

Don't know much about deye, however sunsynk is the same inverter with different software.I'm guessing for offgrid you would need to connect your micro inverter on aux input and control it from there Check out: https://www.youtube.com/watch?v=oWnrFQqLJ74 And for ongrid check: https://www.sunsynk.org/post/ac-coupling-must-watch Hope this helps and solves your problem.

IMO As long as equalization voltage is 52.8v, bulk 53.2v or below and float 52.4v you should be fine.

See manual in previous reply for pinouts . The cable you need is a RJ11 to RS232 USB and is made by Diverse Solutions. I'm pretty sure there are people that have made there own just need to find the correct RS232 USB,if you search for other threads you will find

All pylontechs have RS485 port which is RJ45 and as far i know the RJ11 port is only used with Pi with ICC/Battery viewer not connected directly to Inverter. See manual for US3000 and pinouts US3000-Product-Manual-18BQSV0801.pdf

If you had bought a pylontech cable kit the comms cable comes in it. Its simple for RS485 Inverter RJ45 with pinouts 3 and 5. Battery RJ45 pinouts 7 and 8. (5 to 7 and 3 to 8). Hope this simplifies things.FYI If you are based in the South of JHB I will supply you one for free

Yes they are different slightly. If you have UP5000 why are you looking at pinouts for US3000.... I have not tried it using RS458 only CAN and that works fine. The side that plugs into the batterry is the side you have NOT connected pins 123 and the other into the inverter

I can asist with this the dip should be ONLY on master but on UP5000 its inverted so it should be 0-0-0-1 see pinouts below for UP5000

Hi, Normally paralled inverters use only one battery bank Yes. if you intend on splitting your loads not master and slave

Hi, In my opinion heatpump and Yes. With a heatpump connected, 3.6kw heatpump with loading valve uses 860w only and with correct heat pump installed hot water wont be an issue for all. FYI. If you have a problem of unequal pressure,you should install a cobra master flow kit at your feed.
