So sorry to hear about your problems. Sadly I am now seeing often seeing "installers" that will not do aftersales service. . Name and shame them! Also what area are you?

Just some feedback.... I switched off the AC supply to Slave inverter for weeks with no problems. But that was because my 14kW bank always make it through the night. Last night I forgot to switch off my borehole pump and at 2am the system tripped when the battery got to cut off voltage. The Master can not switch to utility if the Slave does not also have AC supply. @Calvin I remember you mentioning that you would be surprised if this works. You were right, it does not. If one is off grid, both are.

You can bet on it!

You cant bring into account degradation of the battery but over the same period exclude Eskom tariff increases. (On average 11%p.a over the last 10 years)

Did you ever pair it with another phone? I think I have read somewhere that it can only pair with one device.

I am running 2.49 and 71.93 and no issues with the bluetooth. It must be something else. Are you trying to use the watchpower app?

What was the issue with the Bluetooth? Are you using an iPhone?

Yes you must. Upgrade the MCU first then DSP. Good luck with this. It can be frustrating for some.

Seeing that you dont want any sort of backup a Grid-tie setup would probably be best suited to your needs.

On the OG models it is Menu 28. Just change it to "SIG". (The inverter must be off when changing this)

Yes I heard the same when I installed the second but it works. Does not seem to matter which one or in fact both have Grid or not.

You asked the question. This would be directly related to you settings.

None of this is charged? What do you mean? What is your settings, SBU,SUB, USB?

I must say my system is running flawlessly. I run them SBU. Slave utility supply switched off permanently. Only master allowed to charge from Utility at Max 2A. Both not allowed to BYPASS. I have no issues starting 2.2kW pump even with 2kW loads on. Also no problem boiling kettle with 4kW loads running. Battery full by 16:00. Surviving every night with bank still at 24-30% SOC. Back to grid set at 48V. Not using Watchpower, ICC or any software at this stage. Although I use watchpower app to check things from time to time. I am very happy.

What monitoring software are you using? I suspect that it goes to Line mode, charges the battery and is back on battery mode when you wake up and thus you assumption that it does not go to utility.

I seriously doubt your batteries would survive a night. You only have 4.4kW of usable storage. So at some stage, pending your settings, Grid would start charging your battery + take over the load duties. At best you can set the maximum Utility charge to 2A (Setting 11) and hopefully the batteries wont be fully charged by sunrise. Also remember that on battery mode you should not be using more than 50A or 3600W

What panels are you using and how is it connected? Fuses? DC breakers? Did it work before or is the a new install?

Hi Where is the store/stock? Which area?

Do you maybe have link where I can buy this cable?

😀 My life story.

I am running 330W in 3S4P. Yes I sometimes go over 130V but that is rare occasions with cloud edge or cold wind, maybe.

You can also add another 3 panels and wire them 3S3P x3. Pending your roof or space, consider doing one of these arrays facing east. You always need that early morning power for the batteries. Get a extra set of Pylontech cables and wire the bank from "both sides" (Using opposites for each set) You don't set the slaves or master, it is randomly assigned. On my system it seems like you can manipulate the assignment by starting the master a couple seconds before the slaves. (might have been random luck on my side) Otherwise you just start them all, check which one is the master and plug Pylontech comms into that one. The slave will give 61 errors. Make sure the cables are the same length & Spec for each inverter.

In a bank master is 1 0 0 0 and slaves 0 0 0 0 That is how mine is and it works

I'm pretty much off grid. The only way we know its loadshedding is the messages on the community group. That's why it is becoming more difficult to expand the system.
