Removed from working system, now surplus to requirements. May be suitable for a DIY battery system. I also have some single pole from the same range, contact me if interested. Can post in UK for free. £90 ono

slightly off topic but shouldn't that isolator be after the smart meter?

According to that diagram, the Solax inverter needs to monitor both the grid import/export and the other inverter, so it knows when to charge and discharge the battery. They are proposing to use 2 of those CHINT meters with a RS-485 bus (parallel connection). So assign a Modbus address of 1 to...

Just signed up for Flux. I only have PV at the moment but the increased export rate will outbalance the extra cost of import during peak times for me. Once I get a battery I will re-evaluate. As I don't have an EV, I don't have access to Octopus Go or Intelligent.

if you have a measurement showing 8000W then it's likely above 30A, yes. Divide power by voltage to get approx current.

kA rating is not relevant to the tripping, that's the maximum short circuit current the MCB can handle. 8000W is about 33A so although the MCB shouldn't immediately trip unless the current is much higher, it is undersized. I would ask the electrician to run the correct diameter cable and...

thanks! I am holding off contacting them as they are still working on my meter export MPAN and don't want to mess that up. It's taken 2 months already!

My grid voltage is fairly high - approx 245 V to 250 V overnight is common. On some sunny days my inverter trips on AC10M error, which is 10 minute average voltage too high. There is the option of increasing the trip limit in the inverter. I think it's currently set to about 255V. Question is...

codes disabled on those products still i think?

that's a great setup - do you have a wiring diagram?

That's super interesting, I will wait then!

I phoned SP Energy Networks (I'm based in Glasgow) to ask about charges for processing a G99 application (I currently have G98 for PV and want to add AC coupled battery, 3.6kW output) and the guy said 'there might be a charge, maybe a few hundred quid but you have to submit an application to...

It is X1 Boost and that second pinout matches the manual. I will check inverter settings to see whether Meter or CT is configured.
