I'm of the opinion that you should add BSL to you list.. IMHO the best off all batteries support wise I Bought 1 new BSL in 2020 and have been adding 2nd hand batteries as I go along I paid R25k new and 8k 2nd hand, all where recently remotely inspected by getoffgrid as they are still under warranty

I paid 10K for a used one 6 months ago inc Dongle..

Requirement Fullfilled Thanx

Get the CBI ASPI Astute Device and install in DB Board// Then Connect S1 to Escom / GRID and S2 to Inverter Load Side or Aux It is also a Wifi Device so then you can program the other devices based on its status

I came right thanx, not needed anymore..

I'm in the market for a Good Used Deye / Sunsynk Hybrid 10kw/12kw Single Phase Inverter An 8kw may be my plan B as well If I dont find one.. If youre an Installer, even better so as I need to upgrade my 5Kw Sunsynk Hybrid Centurion Area pm me

I have a 5kw Sunsynk (5K-SG03LP1) In existing use, no problems whatsover, bought and installed DEC 2021 via a reputable installer. I want to Sell. Also Included: 2x Hager 2P 40A MCB Breakers (M240Z), 1x Hager 2P 40A ChangeOver (STFT240) , 1x 12way Eurolux Surface PVC DB, 1x 1P 40A CBI Breaker Also included: Custom 12V blower 3x fan assembly via temperature controller I want R13 000 for the 5kw Inverter inc Breakers & Fan I reside in Centurion close to the SA Mint

I will try to be Practical by my own example.. What works well for me as that I have the AUX port Wires going to a CBI ASPI Wifi Clever Non load switching Device.. Via Sunsynx Aux Settings, When SOC is 90% and PV PRODUCED is set to eg 2200W, this device activates an indicator light and activates a Tuya Device Status Called Alternative On. The CBI ASPI Device also has an indicator light Called Mains On . The Tuya Device Status is Called Mains On. (Fed From Escom Grid Connection) I then have a Tuya Automation Scene (GeyserWise ASPI ON) that Activates my Geyserwise Wifi Keypad to push Expected GeyserTemp to 70 Deg C and Switches Geyser On.. Via Sunsynx Aux Settings, When SOC Drops to 80%, the port Voltage then drops and the Tuya Device Status Called Alternative goes Off. A 2nd Tuya Automatiom Scene (GeyserWise ASPI OFF) that Sets Geyser Temp back to 50 Deg C and Switches Geyser Power Off This way I am able to dump backfeed AC to my 2 Geysers on Non Essentials when battery full and PV is generating without ANY Additional AC Wiring to the 2 Geysers.. It can thus also activate any other TUYA Device via the Scene, either Essentials or Non Essentials as it is thus software based. What is not foolproof is that if the PV Produced is also used internally and then you dont actualy have 2200W of free power to use, but the SOC is still a very good indicator together with Scene Automation and Weather Accessed Algorithm.. With Enough PV in your system you could still even wire the AUX port Directly to a device eg Pool but then it is soley dependant on the port, unless you also have a Contactor on the port As I am also feediing the grid, I prefer to first Dump my PV power Internally before exporting, a difference of about R1.50 / kw I am in the process of Getting a larger Inverter to have more PV to Feed and Direct. https://cbi-lowvoltage.co.za/aspi https://play.google.com/store/apps/details?id=com.tuya.smart&hl=en_ZA https://www.geyserwise.com/our-products/geyserwise-electronic-thermostats/geyserwise-tse1-with-tuya-module/

I also use the 5kw BSL with 5.5kw Sunsynk Its very important to set them up correctly to get full utlitzation. I find very few installers I have spoken to does anything else than a "Safe" installation which means one can potentially lose up to 40% utilization.. My Batteries never used to go below 60% SOC where now I hit 30% daily Could one easily add a 2nd 5kw BSL Battery after 6months or so ? And Adding a 2nd hand one ? I may juts be in the market for another one

Please PM Contact Details

Maybe in conjunction with a cutt off type controller as below Adding a Diode will also be a good idea to stop backflow It is uncertain what the Max Amps is even though relay handles 20/30A Maybe an all in one Buck/Voltage Switch is available ? I would also be interested https://www.robotics.org.za/XH-M603 https://www.robotics.org.za/XM-M604

@phidzHave you configured Aux before for GEN/MicroInverter/Output ? Do you know if one can feed 800W in via 2nd Inverter through Gen port configed as MicroInverter ?

I suspect Setup of BMS, PM supplier with Screenshots..? My LBSA DALY 100a 4S 12V LiFePO4 Smart BMS with Bluetooth works 100%

IMHO There are 2 reasons for bonding panels to shortest path to ground earth: To attempt to neutralize static build up on Solar Panels, which in turn attracks lightning To Dissepate energy to ground incase of a lighting strike, via shortest route and away from electrical equipment, Grid and infrastructure

My Electrician and HOA insisted my Panels get earthed directly to under 10 Ohms They both say it is the new SANS requirement, so I had to do it to get signoff That resulted in 4 Rod positions being drive into soil. 2 sets of 3x 1.2m rods and 2x 1.2m rods bonded on 16mm earth wire over a distance of about 12m away from where it exits builing The DB earth and PV Box Surge Protector Earths are joined but may not touch the Solar Panel earth

Hi Glad you are finally getting somewhere, it can be so frustrating.. So you now bonded Neutral and Earth coming out of the Sunsink Load Port ? (I'm setup Like that) Are you now feeding the Sunsynk Inverter from Generator via the Gen Port ? What bonding did you do on the Generator Side ? Do you think reducing Gen Input load below 5kva wil work ? See My post where I am trying to get info:

Has anyone ever done something similiar as above or fed Micro Inverter into Gen Port ?

Currently running a Sunsynk 5Kw Inverter and 5Kw BSL battery and Its fed by 4.5 kw Panels facing North on a Flat roof Typical Config is feeding Essential DB Circuit and rest of DB via backfeed and Ct Clamp Monitor In the mornings I end up with 60% Battery Power Left and my typical consumption is 1000 kw per month, 30kw ish per day of which I buy 25% Als have a mostly unused ready to go Camping/Backup/STHF Inverter setup worth almost 20k 800W/12v Phoenix Inverter a DIY LithiumSA 12V Lithium Battery Bank with BMS (8 Cell 120A), thus about 2.5kw and Bluetooth Kit a Victron 100/20 MPPT 1x 290W Roof based Solar Panel topping up the battery on its own 12V 20A 3, port 12v Victron Charger (Offline) I also have 2x 160w panels (top one Active) on my 4x4 with 1 Extra High Cycle Battery running a Ctek Vehicle Solar Charger This is handy for camping Question: Will it be wize to feed my Victron 800W/12v Phoenix Inverter on the Generator Port Benefits I can count on ? How to configure ? If I can adjust my seconday camping setup, what should I do? Other advice ? Hope I can get some advice, thanx in advance..

I dont seem to find anyone who stocks this at the moment here in Centurion Please let me know if you definitely know of one or have one https://citel.fr/en/photovoltaic/type-2-pv-surge-protector/ds50pv-50051

Thanx for the feedback .. Im either feeding a 12v Inverter for my study servers or using it for my shacks Ham Radios. I need to ensure that I have a 2nd working system even though the house is on a 5Kw Sunsyk, 48v system In the past Ive also tried using a 24/12 DC to DC Converter but there are issues.. When Camping my vehicle etc is already setup for 12v so easy to stay 12v Looks like Im going to have to just bite the bullet..

Background Study use: 2x 330w x 38v Panels in Series I propably did a calculation error using 2x 330w x 37.83v(Vmpp) BYD Panels in series and acquired a Victron SmartSolar 100/20 MPPT (2 weeks old) According to Victrons calc 'n could be losing 30% +. Im now getting 20A in at best loooking at the Victron Connect App If its in fact true, Id like to charge my 12v 240A Lithium battery quicker during loadshedding, even add a 3d panel later on.. Camping: 2x 160w x 18.6v Panels in Series I also want to utlize this 100/20 MPPT when camping with 1 x 160w x 18.6v panels or 2 x 160w x 18.6v in series and might add 2x more panels later... Question/Advice Will a Victron 100/50 MMPT Controller (Or bigger) produce 30% more Power ? Trade if my theory is correct Id like to see if someone wants to trade in my 100/20 on a new or good used 100/50 or bigger without me taking too much of a knock Perhaps sell mine for R2500 if there is interest any Advice/Offers will be considered I do hower need the SmartSolar/Bluetooth feature else im running blind I am in Centurion Tx in advance
