SYC

Hi, Welcome to a wealth of knowledge. Sounds like you want to be where I am😉 🤔You are correct 8k Sunsynk with atleast 2 x UP5000 and build from there in my opinion (Warning!!! its a rabbit hole financially but well worth it) Put heat pump on Aux port when you installed solar

Being an installer I have 1x us2000 2x us3000 1x us3000C and 2x UP5000 all in one bank working fine see pic below From the pylontech manual verbatum: 15) Compatible with the US3000C, US2000C, US3000, and US2000. *Mixture using master battery priority: UP5000>US3000C>US2000C>US3000>US2000 For same type of module always use the latest production unit as master. *Mixture using battery deployment option: Master battery (1st) UP5000 Slave 2nd ~8th UP5000/US3000C/US2000C/US3000/US2000 Slave 9th ~16th UP5000/US3000C/US2000C Please take note of order of batteries above if and when stacking. They all are 15 cells i'm pretty sure Only down site is the you need to limit your draw to the smallest battery in your bank Mine the max I can draw is 1.9kw continuously because of US2000 (FYI lithium batteries work well between 95%-35%) 1st ALL Batteries "HAVE TO BE Balanced" or else you will get an alarm on batteries Inverter MUST communicate with Master batteries BMS

@PowerUser https://www.victronenergy.com/upload/documents/Wiring-Unlimited-EN.pdf Please read documentation above will give you all you need to know,as well as technical explaination for all our esteemed professionals🤔

Yes,same length (shortest as possible if makes sense) and size

Your plan/steps taken sounds spot on Great choices, I would get the 8kw machine once off coz if need be for more power (budget depending of cause rather save up) I have the sunsynk version and they work excellent

Hi, Location please Is icc bought from iccsoftware Manie or other

🙈 Thanks man just just figured that out

Hi, Could someone please assit me with comms cable pinouts for Sunsynk and Hubble AM-2 to communicate with each other Please state wether its for CAN or RS485 Thank you

Hi, I have the same issue, if you don't mind sharing the pinout on comms cable

Just my hummble opinion if i were you,i would build a structure on the wall (from wall to wall) and lay my panels flat In other words raise them

My opinion/What i've done: Would be to install a 3kw heat pump it uses on 750w to get job done and it has a timer,so can set when it goes on and off

Firstly buy the exact same panels a stated above. Your 150/100 MPPT can take 5800w of solar = 14 x 420 Improtant just keep your 2 string configuration as to not exceed 150v

Apologies I'm not very fimiliar with solis, if you don't get an answer here You will need to contact installer/supplier

Switches off Don't know Yes.Thats why I suggested ICC so that you can automate the process (setup once and than it does it by itself there after) Yes and he needs to start with 2 Modules Automate change from utils to battery and back to utils

Yes 10yrs warranty Correct FYI Lithium batteries need to used daily irrespective of loadshedding or not (if memory serves me correct by 20%) if not used warranty will be come void IMO 2 x US3000C Modules would be safer as to not void warranty on battery and I would leave the fridge/freezer, inverter serves as protection from surge as well I would get pi with ICC and pylontech BMS cable (https://iccsoftware.co.za) to manage SOC of battery correctly

Ok than you should be fine The pylontech is extremely cheap at that price (think that was a mistake or priced for black friday😉)

FYI the Fusion King will do the same thing

@Jaco Kotze Might be your dip switch settings are wrong put the master battery on 1110 and slave to 1111 Important for US3000C DIP switch has been deployed reversely. ON is down, OFF is UP. If DIP switches need to be 1000 then set it to 1110. MAX DISCHARGE AND CHARGE RATE IS ONLY APPLICABLE FOR +- 60 SECONDS

Yes and much more in terms of utilization of PV for essentials and none essentials Hope it makes sense Daytime used Night time used

Sorry made a typo meant he WONT look back Use a busbar for battery/mppts and check out https://www.victronenergy.com/upload/documents/Wiring-Unlimited-EN.pdf for correct cable sizing

Hi, IMO best choice your friend has ever made and he would look back Warning becomes costly maar Goedkoop is Duurkoop!!! Depending on his setup/needs GX device Cerbo or Venus Multiplus II 5 kva or Quattro MK3 cable ET112 with RS485 to USB Cables to connect MPPT's to GX device/Multi to GX And cable to connect battery to GX (https://www.victronenergy.com/live/battery_compatibility:solar_md) FYI get someone that is victron certfied to install not simple as voltronic and other setups Not to worry Victron is very versatile that way, works intelligently

Can you please PM password to extract

👍 Might be firmware related the drop to zero or mppt is faulty @Coulomb will be able to assist further

From @Coulomb grand masters signature: If using 72-cell panels with a 145 V max solar charge controller, always wire 2S! Never 3S! Your machine has 3 x 145V mppts
