Are you putting together a battery to connect to a grid tie inverter?
Does the BMS have to talk to the inverter for charge control?
This is something I'm looking into. The cheap BMS can generally communicate on serial interface (RS485) The inverters seem to use MODBUS. If I can find out the protocols it should be possible to use an Arduino to link them together. All the inverter really needs to know is the SoC. Error states would be good as well (eg outside temp and current limits).Yes, I am. Hopefully two Lux hybrid inverters running in parallel.
That's the big question.
All the Lux inverters for sale in the UK seem to specify that you need the Pylontech batteries, which are too expensive for me.
But the Lux manual states it will run any lithium or even lead acid.
The lithium option does seem to require a comms cable.
But if lead acid is connected then all is required is a temperature sensor. So it doesn't need communication to function, but I don't know if it'll cause me problems if it doesn't communicate with a 3rd party lithium battery.

if you're quoted DDP then there should not be anything more to pay. VAT and duty will have been "paid". Say no more.Did Amy add a percentage on to the base price for taxes to be included?
The extra for DDP is not much. That tells you all you need to know about whether the VAT has really been paid.Did Amy add a percentage on to the base price for taxes to be included?
What's a brexit surcharge and who applied it? Sounds a bit bogus to me.I also got hit with a $24 brexit surcharge due to the extra paperwork, I bought mine start of December so don’t know if it’s any different now.
