Hello,
Newbie here. Just upgraded my existing 14 year old grid-tied array (SMA inverter) to a Sol-Ark15Kw inverter with 3 eFlex batteries.
I was thinking about adding a Solar Assistant Pi unit to the mix, to better monitor my system (although it’s a bit disappointing that for the Sol-Ark15, it is read only).
All my equipment is outdoors. The Sol-Ark is in a custom made steel cabinet, and the eFlex batteries are in a DuraRack enclosure.
I was going to put the Raspberry Pi in the steel cabinet, next to the inverter, but it’s too hot in there for a Pi to survive for long.
I was wondering if the following is a solution:
I currently have the Sol-Ark wifi dongle wired with an ethernet cable (coming from inside the house). If I put a RJ45 splitter on the can-bus, put the eFlex BMS on one leg of the spliitter, can I use the existing ethernet cable (disconnect it from the dongle, since the dongle can use wifi), connect it to the other leg of the splitter, and then couple that ethernet cable to the proper (RJ45 to USB) cable, to plug in to the Pi? Essentially, I’m trying to use the existing ethernet cable as a long extension cable, so I can run the Pi inside the house.
Would this work?
Thank you all!
