Battery and Inverter communication

Featured Replies

Depends on the inverter you use... I have seen inverters that only utilize CAN or RS485 but others that can use both. Would you mind clarifying which inverter and battery you are using so I can hopefully offer accurate advice?

Luxpower SNA5000 and Bluenova BN53 batteries, what I understand from the manuals both can do both, so not sure if I should connect both or just use CAN or RS485

i would like to know if any inverter has a RS485 port and the battery has the same and you know the pinouts for inverter and batter with that work communication  ?

Ok, so it looks like the BlueNova would prefer the use of CAN communication protocols:

However, you can wire both the RS485 and CAN cables since the inverter have both spread over a different pins:

On the brighter side, BlueNova seems to provide all the relevant charging parameters as shown on page 4 of the manual.

And the Luxpower manual shows these can all be configured via the relevant software, see page 20 of the manual:

Hi Guys

 

Found this website that lists some inverters that are compatibile with certain batteries. Also a Section on Learning about Installing solar systems in South Africa.

Let me know if it was a good recommendation.
