Spare MPPT I've had on the shelf for a bit. Still taped up in the original plastic/box. $200 picked up or how about $220 shipped ground in the US. In Lafayette, CO

You need to understand the function of the BMS. It should be monitoring individual internal cell voltages. If a cell is going too high or too low, it'll cut out charge or discharge respectively. Once you give up on the company, you may want to consider adding a different BMS. Either way, I'd at...

Still available.

Yes, I'm around! I'll PM you

I can check the charge state if you're actually interested. They had a nice charge but have been sitting.

I still have these and just moved. $1500 to get them out of my shop. The description was a bit off, I have four. 3x are perfect, the fourth has the corrosion. I may just turn them into a power wall, dunno.

Enjoy.

You know what, sure. I'll be one less thing in my pile of stuff. Paypal or venmo works. Let me know and I'll pm you details

For the JR2, I'd go for 300 shipped CONUS.

The JR2 I have is model J2BMS16C. 500a hall effect. Harness connectors are all there, but you can get replacements from orionbms.com if you want to re-cut them. I mostly kept things intact since I kept messing with my physical install for a while. I paid $656 for it in Jan 2022.

I'll go look in a bit. I just moved but I think I know where I shuffled things around to. Yes it has the hall effect sensor, amps are dependent on the contactor. The hard lesson I learned there was to make sure you buy one with the economizer.

The rec needs to be configured via firmware to talk victron compatible canbus sentences. In theory you shouldn't need additional software other than the can driver to get it to work. I use a cerbo on my boat with my REC. For me it's worth it to run the cerbo since I also have a WS500 alternator...

I see you already mentioned the solar breaker... so let's say that you need to consider your schematic the source of truth. Mark that you have mulitple, etc. Note that things are simplified or whatever or we can't really give you complete feedback.

OK, let's talk about this a bit. I don't know what's being added vs augmented here. It would be a good idea to identify existing/new so that you can determine if something should be replaced or re-sized. A 50A breaker behind a 15 amp MPPT is wrong. You should have a breaker that matches the...
