I though about the same at one stage. What if you take a normal 48V lithium charger and attached that directly to your battery buss bar. You connect that to your 1kw generator With that you can go up to around 20A charging. Maybe just as a backup to keep the batteries going through the night until solar pickups again.

I think the installer was in the wrong here to install 4mm2 cable. Thus limiting the inverter and any future upgrades to save R700 on the cable costs. I agree not to pass the COC on this but for the installer to fix. From the quotes I have seen a lot of installers asks design costs but in this case there was no design done.

The problem is not about getting 10KW out of the inverter. The problem is 10kw into the inverter. The inverter above have a 120A AC charger for the battery. That is 120 x 54v for charging is already 6.5kw. The inverter has a maximum AC Input Current of 40 A . 40 x 240 which is 10kw. So 40 is above the rating for a 4mm2 cable

Does your inverter stop suppling power to the plugs and lights when it charges the battery?

How much will that inverter pull if loadshedding stops? Charge batteries - 120A - 6kw Running everything in the house that is connected. - 4kw. As now people start cooking and using the plugs. That is 10kw on a 20m 4mm2 cable.

What if you use micro inverter on the GEN input leg?

A quick solution for real time monitoring is a cheap 485 converter en raspberry pi zero w. And you install node red with a light dashboard on and then on your home router you just forward your port to access the dashboard externally. Then you can see it both internally and externally. I can get the reading but from those docs I don't know how to set change a setting. I ideally just want to change the use timer setting if I see loadshedding will catch me out.

I hope they have a exchange policy for the people that bought the old logger and now wants the new Sunsynk one.

Is this for a completely off-grid setup? And is there backup generator if it is cloudy for a few days?

Another one, did you imports someone else's code? Try and delete everything and setup just an injector switch a function and modbus flex getter node with debug.

This is my settings that is working. Node-red version : 0.20.8

I have heard numerous problems with those cheap ones. Best would be to try one of these. https://www.robotics.org.za/RS485-3P?search=485

What RS485 converter do you use? Might cause a problem. I run mine on a raspberry pi zero w without any problems. I go from (inverter)RJ45 -> rs485 to usb converter -> usb extention cable -> usb to micro usb cable -> rpi zero. And also use a cheap usb power adopter without any problems

What is your guys polling timing set to? I have mine on 15sec. But don't want to overload the inverter data side.
