Title: Lithium Batteries that interface w/Rosie CANBUS
Post by: aaapilot on June 28, 2023, 10:51:56 AM
Selecting lithium batteries to go with a Rosie/Hawks Bay combo.  Many rack-style batteries interface directly with newer inverters via Canbus or RS-485, as well as UL9540 cert for markets requiring the certification.  Can anybody comment on plans for Rosie in this regard or is it already capable?  Looking at Pytes E-Box 48100R, EG4, etc.  I realize that just about any battery CAN be used via independent settings, but it would be nice if the batteries were plug and play just like the Rosie/Hawks Bay combo.  Thanks all!

It may come with time, but first Midnite has to get their combox developed since that would most likely be the interface between batteries and controllers and inverter.
As far as I have seen there is no truly plug and play , everything needs to be set up and monitored. Everything can get glitches and needs updates.
With batteries you mentioned then you are relying on their BMS to supply data to Midnite products so it would only be as reliable as the batteries data and communications. Most present bms don't do what they ideally should or would.
If you haven't ever seen it, take a look at Off Grid Garage on youtube. Andy there has played around and installed lots of different products with different lithium setups. He often runs into issues which he tests and describes very well.

Thank you very much for the reference, I'll take a look! Your point is well taken about information exchange w/different manufacturer's gear.  You are just one electron or software update away from trouble.  Programming hard numbers into the inverter/charger leaves no doubt. :)
